1 Introduction

The IWF Metadata Harvester is a package for extracting data from servers, writing it to databases, and displaying it.

Numerous libraries, archives, and other institutions provide data publically or on a restricted basis on servers dedicated to this purpose. For example, many libraries make bibliographic data on their collections available on a server, for use by other libraries. Another institution or private person who wishes to access this data does so by means of a client application or client. Such a client initiates a connection to a server over a computer network and requests that the server send it particular data by means of one or more queries. If the data is available, the server then responds by sending the data over the network to the client. After the client has received the data, and has no further requests to make, it terminates the connection with the server.

1.1 Standards and Protocols

In order for the communication between client and server to function, both must adhere to a common set of standards and protocols. There are many standards governing the communication of clients and servers over computer networks, old and new, for various purposes, and development in this area continues apace.

These standards and protocols and their implementation is a complex subject, and different standards and protocols are not always directly comparable. It often useful to speak of the “kind” or “type” of a server, but it can be difficult to define precisely what this means.

Currently, the IWF Metadata Harvester can access two “types” of server: “OAI servers”, i.e., ones using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), and “Z39.50 Servers”, i.e., ones using the Z39.50 protocol.

The IWF Metadata Harvester contains two programs, ATest and ZTest, whereby ATest accesses OAI servers and ZTest accesses Z39.50 servers. Of the two protocols, the OAI-PMH is much simpler, more straightforward, and more modern than Z39.50, which seems unnecessarily complex and old-fashioned in comparison. Nonetheless, Z39.50 does have some advantages over OAI-PMH, and is still widely used, especially by libraries.

1.2 Retrieving Data


Next: , Previous: Retrieving Data Introduction, Up: Retrieving Data Introduction

1.2.1 OAI

Retrieving data from an OAI server is no problem, because one simply uses the Hypertext Transfer Protocol used in the World Wide Web (WWW) for transferring data in HTML (Hypertext Markup Language) format, such as web pages. Microsoft Visual C++ provides library functions for accessing servers using HTTP, as do other implementations of C++ libraries.


Previous: Retrieving Data OAI Introduction, Up: Retrieving Data Introduction

1.2.2 Z39.50

Ultimately, data is retrieved from a Z39.50 server using TCP/IP, but ZTest does not use these protocols directly. Instead, it uses the YAZ library supplied by the Danish company Index Data.

1.3 Data Formats


Next: , Previous: Data Formats Introduction, Up: Data Formats Introduction

1.3.1 OAI

The data supplied by an OAI server is in XML format. XML has become a popular format for exchanging data in several different areas within the field of computer and database programming. It is a very clearly structured format and allows for a hierarchical organization of data. Because of its popularity, documentation is easily accessible, code samples and software for processing XML data is widely available, and the relevant standards committees are active. The use of such a popular and well-supported format for data exchange makes it easier to use OAI interfaces, because established methods can be used for accessing and manipulating the data. In fact, it was unnecessary to program an XML parser in ATest, because Microsoft SQL Server 2000 provides a system stored procedure for representing XML data in tabular form.


Previous: Data Formats OAI Introduction, Up: Data Formats Introduction

1.3.2 Z39.50

Z39.50 servers, on the other hand, can provide data in several different formats. The most popular is USMARC, formerly known as MARC. However, the IWF Metadata Harvester currently cannot process records in USMARC format. It does process records in PICA format, which is used by the GBV in Germany. The PICA format is much more concise than the rather verbose XML format, and Pica records are correspondingly more compact. However, it is very complex, with nearly 400 categories, each of which has at least one, and possibly several, fields. Since PICA format is little-used, outside of Germany and the Netherlands, ZTest includes a specially-written parser for parsing PICA records. However, it does not yet process all of the categories and fields, and the PICA database does not yet have database tables and columns to correspond to all of the PICA categories and fields.

3 Databases


Next: , Previous: Databases General, Up: Databases General

3.1 Association Tables

The databases which are included in the IWF Metadata Harvester make heavy use of “association tables”. These are database tables that associate entries of two or more other database tables.

Association tables are needed when a data record can contain multiple items of information of the same type. For example, a book may have more than one author. It would be possible to define a “Book” database table with a column “author_name”, but then it would only be possible to store the name of a single author in a line of of the Books table.

A better approach is to define a second table “Authors”. Both the Books table and the Authors table should have a column containing a unique, numeric identifier, book_id, and author_id, respectively. These columns should each be associated with primary key constraints for their table. Let us further assume that the Authors table has a column “author_name”.

Now, a third table, “Records_Authors” can be defined with the two columns “book_id” and “author_id”. These columns should be associated with foreign key constraints referencing the Books table and the Authors table, respectively.

Consider the case that a book has three authors. First, an entry is created in the Books table, and it is assigned a book_id, say 1. Then, three entries are created in the Authors table, and they are assigned author_ids, for example, with the values 1, 2, and 3. Then, three entries are created in the Books_Authors table as follows:

book_id author_id
1 1
1 2
1 3

Now, the names of all of the authors associated with this book can be found by using the following Transact-SQL query:

     select A.author_name
     from Authors as A, Books as B, Books_Authors as BA
     where
     A.author_id = BA.author_id
     and
     B.book_id = BA.book_id
     and
     B.book_id = 1


Previous: Association Tables, Up: Databases General

3.2 “Continuation” Columns

When strings are too long, they are not written to the database correctly, but no error is signalled. However, CDatabase::ExecuteSQL or CRecordset::Open throws and exception, when trying to read the string out of the database: Error Code 1021 ``Daten abgeschnitten'' (``Data truncated'').

This shouldn't happen, because enough space should have been allocated in the database table definitions. However, one never knows what a record might contain, so it's entirely possible that one might contain more text than expected. In order to account for this possibility, some of the tables in the PICA database have continuation columns. !! TODO: Explain.

4 Multi-Threading

Currently, neither ATest nor ZTest uses multi-threading. However, I have made an effort to ensure that it will be possible to do so, if need arises. I avoid the use of static non-constant variables in functions, and static variables local to files, in order to ensure that all functions are thread-safe. There are still some static variables left, but I am in the process of eliminating them.

8 ATest

ATest is a package that retrieves records from servers using the OAI (Open Archives Initiative) interface. The Open Archives Initiative is a body that develops and publishes standards, protocols, etc., for the interchange of data. One such protocol is the OAI–PMH (Open Archives Initiative–Protocol for Metadata Harvesting).

Institutions that wish to make their archives publically available may set up an OAI server. Users can connect to the servers using The records are transmitted over the internet using the Hypertext Transfer Protocol (HTTP) in XML format. The OAI–PMH specifies the XML tags that can be used in the metadata made available via the OAI interface. They are based on the Dublin Core fields.

These are the steps that ATest performs:

  1. Connect with an OAI server and send it a query. If the query is successful, the OAI server responds by returning an HTTP packet containing a set of metadata records in an XML structure.
  2. Write the information returned by the query to a file. Special characters are converted to a coding that Microsoft SQL Server 2000 can handle.
  3. Process the file of XML code. Extraneous information is discarded, and individual records are extracted and processed sequentially. Information is extracted and Transact-SQL commands are executed, in order to write this information to the appropriate tables in the dc_test database.
  4. Once the data have been written to the database, other functions can be called to search the database and display its contents using various options.

17 ZTest: Z39.50

ZTest is a package that retrieves records from servers using the Z39.50 interface, extracts information from these records, writes it to a database. It also provides various ways of searching and displaying this information.

Z39.50 is a set of standards, protocols, etc. It is used by many institutions throughout the world, especially libraries. It is a rather old set of standards, and quite complex.

!! TODO: Check the information in this paragraph. A Z39.50 interface can provide data in a number of different formats. Currently, ZTest can only process data in the PICA format. This format is widely used in Germany and the Netherlands, but not much elsewhere. The most commonly-used format is USMARC (formerly known as “MARC”). It would be desirable for ZTest to be able to process USMARC data as well.

The term PICA actually refers to a a pair of formats, Pica+ and Pica3. Librarians who catalogue data and prepare it to be made available via a Z39.50 interface use Pica3. This data is then converted by a computer program to Pica+ format. Pica+ is thus the format of the data retrieved from the Z39.50 interface and is what ZTest processes.

18 How ZTest Works

When ZTest is started, a dialog box is displayed. This dialog box is associated with the class Dialog_Z_1, which is described in Dialog_Z_1 ZTest. Clicking the “OK” button will cause the event handler Dialog_Z_1::OnOK to be called. See Event Handlers. Dialog_Z_1::OnOK, in turn, calls the global function zoomtst2. See Global Functions. Assuming all of the options are checked, zoomtst2 performs the following actions:

  1. Create a ZClient object.

    An identification number, the name of the server, and, optionally, a port number, are passed to the ZClient constructor, e.g.,

              ZClient z(ZClient::GBV_GVK_ID, "z3950.gbv.de:20010/GVK");
         

    See ZClient; Constructors. ZClient::GBV_GVK_ID is the identifier for the the German Gemeinsamer Verbundkatalog (GVK, engl. Union Catalogue) of the Gemeinsamer Bibliotheksverbund (GBV, engl. Common Library Network). See ZClient; Static Constants. The corresponding server, i.e., z3950.gbv.de:20010/GVK, is so far the only one addressed by ZTest.

  2. Initialize ZClient::category_map

    ZClient::category_map is a protected data member of ZClient, and is of type Category_Map_Type. The latter is a type definition (or “typedef”) for map<string, Category_Container*>. See Category_Container.

    Initialization is performed by the function ZClient::init_category_map. See ZClient Initialization.

  3. Search

    The search query in the edit box will be sent to the Z39.50 interface.

  4. Write records file

    If the search is successful, the Z39.50 interface returns a stream of data containing bibliographic records in Pica+ format. This data is written to the file records.txt.

  5. Clear database (only if parsing)

    The function ZClient::clear_database causes the Transact-SQL stored procedures delete_tables and regenerate_tables to be executed in the PICA database. See ZTest; Database Stored Procedures.

  6. Parse records

    The function ZClient::parse_records is called with the string "records.txt" as its argument. Parsing is somewhat complex. ZClient::parse_records is described in ZClient; Parsing.

  7. Display records

    An object of type DB_Display called db_display is created. See Displaying Database Contents (DB_Display). Then, the functions DB_Display::open_html_file and DB_Display::display_records are called on it. See DB_Display; Output. They cause HTML code to be written to the file whose name is passed as an argument to DB_Display::open_html_file, currently, "records.html".

  8. Clean up and exit

    Call ZOOM_resultset_destroy and ZOOM_connection_destroy to clean up. !! TODO: Document these functions! LDF 2006.09.11.

20.2.7 Parsing

— Public Functions: int parse_records (const char* in_filename)
— : int write_field_data (string& category_id, string& repeat_code, char field_id, string& field_value, Pica_Record* pica_record)

Together with Pica_Record::write_to_database and other functions mentioned below, they implement a lexical scanner a.k.a. a low-level parser. See Pica_Record; Writing to Database.

parse_records first opens the file whose name is passed as the in_filename argument for reading. Assuming this file exists, it then reads its contents character-by-character. It thus uses the “category code” approach to scanning, as in Donald Knuth's TeX and METAFONT packages, and in the author's GNU 3DLDF package. A more common approach to lexical scanning uses regular expressions. Lexical scanners using regular expressions are often programmed using the lex or Flex packages.

Assuming a successful search, the input file will consist of one or more records in Pica+ format. (If the search was not successful, it will contain an error message). A record consists of one or more non-blank lines. A blank line marks the end of a record. Each line begins with a category id, which consists of four characters. These may be letter, digits, or the commercial “at”-character: @. Typical category ids are “001@”, “021A”, or “045G”.

A category id may be followed directly, i.e., with no intervening whitespace, by a repeat code consisting of a slash, followed by two digits. Typical category ids with repeat codes are “029F/01”, “045Q/02”, or “028C/03”.

A single space character follows the repeat code, if if present, or the category id otherwise. The rest of the line is occupied by one or more field ids followed by their associated field values or arguments. A field id consists of the special character octal 237 (decimal 159) followed directly by a single letter or digit. Octal 237 isn't a seven-bit ASCII character, so there's no universal standard for representing it. It is displayed as “$” in the GBV online-catalogue. However, the dollar sign is represented by a seven-bit ASCII character, namely octal 44 (decimal 36), and this character may also occur in field values, so this convention is potentially confusing.

The field value is at this point simply treated as text. It is terminated by the next field id, if any, or the end of the line. The end of the line also indicates the end of the list of fields associated with the category id at the beginning of the line.

A given category id may be occur multiple times within a single record. Sometimes, subsequent occurrences are marked by using a repeat code, but not always. On the other hand, a repeat code doesn't always indicate multiple occurence of a category id within a record: Some category ids are always used with a particular repeat code, or one of a number of repeat codes. Within a line, a given field id may occur multiple times. There is no repeat code for fields.

parse_records can be in one of four states. It keeps track of this in an unsigned short variable called state. The values are constant unsigned shorts called OUTSIDE_RECORD, COLLECTING_CATEGORY_ID, and COLLECTING_FIELD.

Before it starts reading characters, state is OUTSIDE_RECORD. That is, the state variable has the value OUTSIDE_RECORD. It so happens that OUTSIDE_RECORD = 1, COLLECTING_CATEGORY_ID = 2, and COLLECTING_FIELD = 3, but the actual values don't matter, as long as they differ.

Characters are read within a “while” loop. Before the loop starts, the variable Pica_Record* curr_pica_record is declared and initialized to 0. That is, curr_pica_record is a pointer to a Pica_Record object, but starts out pointing to 0.

At the beginning of each iteration of the loop, a character is read from the input file. The actions performed in the loop are determined by what character it is, and the value of the state variable. This is controlled by a fairly complex conditional construction using if, else if, and else. Much of the complexity is to ensure that all characters are processed correctly under all circumstances, even if the structure of the input file differs from what we expect. However, parsing Pica+ records is usually straightforward.

  1. Skip Whitespace
    There is normally no whitespace at the beginning of an input file, but if there is, it's skipped.
  2. Collect Category ID
    A line always begins with a category id, so the first non-blank character at the beginning of the input file, or at the beginning of a line, is interpreted as the first character in a category id. state has the value OUTSIDE_RECORD; it is now set to COLLECTING_CATEGORY_ID. Memory is now allocated for a new Pica_Record object, and curr_pica_record is pointed at it. In addition, a counter called record_ctr, that keeps track of the number of records we process, is incremented. It will now have the value 1.

    The current character (curr_char) is placed onto the empty string curr_category_id. parse_records now continues to collect characters and add them to curr_category_id until it reads a whitespace character. The category id is now complete. It should consist of four characters, optionally followed by a repeat code. A repeat code consists of a slash followed by two digits, e.g., /01, /02, etc.

    If a repeat code is present, it is now removed from the category id and stored in the string curr_repeat_code. state is now set to COLLECTING_FIELD.

  3. Collect Fields
    The first character following the whitespace that follows a category id or a repeat code should be octal 237, which should be followed by a letter or digit. Each category has a set of valid fields associated with it. These are documented in the cataloguing guidelines (germ. Katagorisierungsrichtlinien) of the GBV: http://www.gbv.de/vgm/info/mitglieder/02Verbund/01Erschliessung/02Richtlinien/01KatRicht/inhalt.shtml Field ids are only unique with respect to a given category id! That is, the same field id may have a completely different interpretation with respect to two different category ids.

    An arbitrary number of characters, including whitespace, may following the field id. These characters comprise the field value. The field value is terminated by a new field id, or the end of the line.

  4. Write Field Data
    When a field value has been collected, parse_records calls the function ZClient::write_field_data, passing the current category id (curr_category_id), the (possibly non-existent) repeat code (curr_repeat_code), the (possibly non-existent) previous field id (prev_field_id), the current field value (curr_field_value), and the pointer to the current Pica_Record object (curr_pica_record) as arguments.

    write_field_data checks whether the current category is one which is handled for this particular ZClient object. Whether a ZClient object handles any given category is determined by the function ZClient::init_category_map. See ZClient; Initialization. Currently, there is only one version of this function, and it is designed for use with the Z39.50 server for the GVK database of the GBV. When ZTest is adapted for use with other servers, it may be possible to use init_category_map unchanged or it may have to be modified. Alternatively, other, similar functions may be defined for use with other servers.

    If a category is “unknown” to this instance of ZClient, the field id and field value we've collected is simply discarded. Otherwise, write_field_data checks to see whether a Category_Container object for the present combination of category id and repeat code has already been created and placed onto the Category_Multimap_Type categories data member of the current Pica_Record object. If so, it will be used for any further actions. Otherwise, it will create a new Category_Container object, if the current field id is also known.

    The next step is to check whether this is the case. If the field id is unknown to this instance of ZClient, no further action is taken, and write_field_data exits. Otherwise, a new Subcategory_Container object is created, and it together with the current field id are placed onto the Subcategory_Vector_Type subcategory_vector data member of the current Category_Container object. (Subcategory_Vector_Type is a type definition for vector<pair<char, Subcategory_Container*> > Subcategory_Vector_Type). Please note that a new Subcategory_Vector_Type is always added to Category_Container::subcategory_vector; A given field often occurs more than once within a record line.

  5. Write Record Data
    A record ends with a blank line, or an EOF (end-of-file), which also indicates that the current record is the last one. parse_records now calls the function Pica_Record::write_to_database on *curr_pica_record, i.e., the Pica_Record object referenced by the pointer curr_pica_record. At this point, the Category_Multimap_Type categories data member of *curr_pica_record contains all of the information for the categories and fields that parse_records has collected in the previous steps. Category_Multimap_Type is a type definition or “typedef” for multimap<string, Category_Container*>.

    A pointer to the current ZClient object is passed to Pica_Record::write_to_database, along with a pointer to a CDatabase object that references the PICA database. See Database Tables for ZTest, and a reference to Output_Stream_Type used for accessing a log file. write_to_database now iterates through the Category_Multimap_Type Pica_Records::categories data member, referencing each Category_Multimap_Type (i.e., pair<string, Category_Container*>) object on categories in turn. categories is a multimap rather than a map, because there can be multiple lines for the same category within a single record. It's convenient to use a multimap in ZClient::write_field_data, but in Pica_Record::write_to_database, the order of the categories doesn't matter, so it just iterates through them from beginning to end, as though it were a vector.

    write_to_database now extracts the category id from the current Category_Multimap_Type object, and looks it up in the Category_Map_Type category_map data member of our ZClient object. This is the map that's initialized by ZClient::init_category_map. If a Category_Map_Type (i.e., pair<string, Category_Container*>, just like Category_Multimap_Type) object correspoding to the current category id is found on ZClient::category_map, then write_to_database exits. Otherwise, it iterates through the pair<char, Subcategory_Container*> objects the Subcategory_Vector_Type subcategory_vector data member of the Category_Container objects referenced by the pointers to Category_Container in the current Category_Multimap_Type object. (Subcategory_Vector_Type is a type definition for vector<pair<char, Subcategory_Container*> >.)

    Now, write_to_database extracts the field id from the current <pair<char, Subcategory_Container*> > and looks it up in the Subcategory_Map_Type subcategory_map data member of the current reference Category_Container from the ZClient object. If no corresponding <pair<char, Subcategory_Container*> > is found, then write_to_database ignores this field and continues. Otherwise, it cycles through the vector<Database_Command*> database_commands data member of the Subcategory_Container pointed to by the Subcategory_Container pointer in the pair returned. If Subcategory_Container::database_commands isn't empty, it will contain pointers to objects of type Database_Command. A Database_Command object contains a data member called function, which is a pointer to a function taking the following arguments:

    1. CDatabase* database
    2. long record_id
    3. Category_Container* category
    4. Subcategory_Container* subcategory
    5. Output_Stream_Type& log_strm
    When write_to_database cycles through the database_commands vector, it calls the function referenced by the function data member belonging to each Database_Command object. These Database_Command objects are on the reference Subcategory_Container object, which is on the reference Category_Container object, which, in turn, is on the ZClient object. In other words, they have no connection with the current Pica_Record object that contains the Category_Container objects that contain the Subcategory_Container objects that contain the field ids and values that we've collected from the records in the input file. Therefore, pointers to the current Category_Container and Subcategory_Container from the current Pica_Record are passed to function as arguments.

    These functions are all static member functions of Subcategory_Container and have names corresponding to the Pica+ category and field ids, e.g., f_001A_0, f_011_AT_b, f_047I_a, etc. They all have the same return type and arguments (otherwise it wouldn't be possible to refer to them all using Database_Command::function). However, they fall into two different types, according to the way they function. Where the information in a field value conceptually “stands alone” and can be processed without reference to the values of other fields, the function can simply cause the appropriate Transact-SQL code to be executed in the database. Sometimes, however, fields are related, and the way they're processed depends on their order, what other fields are present, or other conditions. In this case, the current field id and value are pushed onto the vector<pair<char, string> > database_command_arguments data member of the current Category_Container to be processed in the next step.

    Once all the Subcategory_Container objects for the current Category_Container object have been processed, write_to_database checks the database_commands vector on the current reference Category_Container object. Since many fields are processed by the corresponding Subcategory_Container functions alone, not every category requires database commands for the Category_Container. Some do, however, and these have non-empty database_command and database_command_arguments vectors. The latter contain the field ids and values from the Subcategory_Container objects from the current Category_Container object's subcategory_vector data member, as explained above. The Database_Command objects referenced by the pointers on Category_Container::database_commands are just like the ones on Subcategory_Container::database_commands, except that function points to a static member function of Category_Container. These functions are similar to the field-handling functions of Subcategory_Container, except that their names begin with F_ and are otherwise derived from the category ids alone, e.g., F_001B, F_041A, F_209A, etc. They take the same arguments as the Subcategory_Container::f_* functions, but the Subcategory_Container* subcategory argument is always 0 when they're called. Declaring them to have the same arguments makes it possible to use the Database_Command type both for Category_Container and Subcategory_Container. The Category_Container::f_* functions process the field data stored in Category_Container::database_command_arguments and cause the appropriate Transact-SQL commands to be executed in the database, like the Subcategory_Container::f_* functions.

    Category_Container::database_commands and Subcategory_Container::database_commands are vectors, so that any number of functions could be called for a given Category_Container or Subcategory_Container. However, currently, only one function is ever called for each Subcategory_Container, and either no functions, or only one function is ever called for each Category_Container.

22 Pica Formats and Records

22.2.1 Repeat Codes for Categories

Where consecutive lines belong to the same category, repeat codes may be used, but aren't always. Used in this way, any category code can be followed by a repeat code. 1

On the other hand, specific repeat codes change the meaning of the associated category. In this case, the Pica+ category code may correspond to different Pica3 categories, depending on the repeat code.

!! TODO: Add example.

Currently, in ZTest, an object of class Category_Container is created for each line in a Pica record, unless two or more lines within a group of lines of the same category either have no repeat code, or share the same one. The field codes and their associated values are stored in the same class Category_Container and they are processed as though they had all occurred on a single line. It would be possible to change this behavior, and force lines of fulfilling these criteria to be handled separately. Alternatively, it would be possible to continue to use a single Category_Container, but to handle the groups of fields belonging to each lines separately. One way of implementing doing this would be to push an ASCII null character ('\0') onto the list of field codes. This character isn't used as a Pica field code.

Some of the field values in a Pica+ record contain information that should be unique for that record. For example, a record should have only one Pica Production Number, only one Year of Appearance, etc. The Records table in the PICA database contains columns for this information.

However, many other categories and fields can occur in a Pica+ record multiple times. It is therefore not possible to store all of the information for a ZTest record in a single table in the PICA database. For example, a resource may have one, two, three, or any number of authors. On the other hand, a resource may have no author at all. This is frequently the case for audio-visual media, where other categories, such as “contributor” are used for the names of the creators of the resource. If the Records table contained a single author_name column, only one author's name could be stored in a line of the Records table. If the resource referred to by this record had no author, the column would have to contain NULL or a default value. On the other hand, if it had two authors, one would have to be left out. Nor would redefining the Records table with multiple columns for authors, e.g., author_name_1, author_name_2, etc., solve the problem. With this approach, there would always a fixed limit for the number of authors' names that could be accommodated, and space would always be wasted, if fewer authors were present in a record.

For categories and fields where a variable number of entries are possible, the PICA database uses a combination of foreign key constraints and association tables, as explained in Association Tables.

This implies that the data for a given record will be distributed over a number of different tables in the PICA database. Therefore, display_single_record must first find all of this information in order to display it.

Once the information is gathered, there are many possible ways of displaying it. The form of display performed by display_single_record is designed to be simple and complete, and reflect the structure of the PICA database. The code in display_single_record could be used as the basis for fancier and more complicated displays.

display_single_record writes HTML code to the output file. Each table which contains entries for the current record is represented by a ruled HTML table with fields for the names of the columns and their contents. If the database table has too many columns to be displayed comfortably across the breadth of a browser window, the names of the database columns may appear in a column on the left of the HTML table, with the values in fields to the right. If a database table contains more than one row for the current record, an additional HTML table will be created for each database row. Otherwise, display_single_record will create a single HTML table with the names of the database columns names in a row of the HTML table with the corresponding values in one or more rows beneath them.

The first table displayed is Records table. There is no difficulty in extracting this information from the database, since there will only ever be one row in this table for a record by definition. For the subsequent HTML tables, the entries that correspond to the current record must be extracted from the corresponding database table. This is done in one of two ways, depending on whether the connection between the database table and the entry for the record in the Records table is created by means of an association table or a foreign key constraint in the current database table.

The database table Content_Summaries uses a foreign key constraint. For example, Record 23 may have a content summary, which is stored in the Contents_Summaries table. The value in the content_summary_id column for the entry in the Contents_Summaries table may have the value 92. The Contents_Summaries table also has a column record_id, which references the column record_id in the Records table. Its value will therefore be 23 in this entry. The following Transact-SQL query will return this row from the Contents_Summaries table:

          select * from Content_Summaries where record_id = 23 order by content_summary_id
     

The Authors database, on the other hand, doesn't have a record_id column with an associated foreign key constraint, but uses an association table, Records_Authors, instead. For example, Record 48 may have three authors, and the entries for these authors in the Authors table may the values of 104, 105, and 210 in their author_id columns. The Records_Authors table has only two columns, record_id and author_id, whereby the former references the record_id column in the Records table, and the latter references the author_id column in the Authors table. The following Transact-SQL query will return the data from all the rows in the Authors table that correspond to authors of the resource referenced by Record 48. Please note that select * cannot be used in this query, and that the columns of the Authors table must be named explicitly, because the Records_Authors and Records are both named in the “from” clause of the “select” query.

          select A.given_name, A.surname, A.prefix, A.id_number_ppn
          from Authors as A, Records_Authors as RA, Records as R
          where
          A.author_id = RA.author_id
          and
          R.record_id = RA.record_id
          and
          R.record_id = 48
          order by A.author_id
     

Whether a column with a foreign key constraint or a separate association table is used, Transact-SQL queries similar to the ones described above are used to extract the information for a given record from the various database tables in the PICA database where this information is stored. The Transact-SQL query is passed to the Open function of an object whose type is an class derived from CRecordset (an ODBC class) that corresponds to one of the database tables. See ODBC Classes for ZTest.

ZTest contains an ODBC class corresponding to each of the database tables in the PICA database. For example, class Records corresponds to the Records table, class Authors corresponds to the Authors table, etc. display_single_record declares an object of each of these types. When its Open function is called with a Transact-SQL query, and this query is successful, i.e., it returns one or more rows of data from the database table, the data members of the ODBC class object are “filled” with the data from the first row from the set of rows returned by the Transact-SQL query. That is, the data members of the ODBC class object are assigned the values from the corresponding columns of the first row of data. The order by clause in the Transact-SQl queries ensures that the rows are ordered correctly. display_single_record now uses the “navigation functions” CRecordset to iterate through the rows. Each time CRecordset::MoveNext is invoked on an ODBC class object, the data members are assigned values from the next row of data from the database, until there are no more rows. display_single_record then writes this data to the output file, along with the appropriate “boilerplate” HTML code to format it.

— Public Function: int display_records (
[CString search_command_str = "",
[const unsigned int start = 1,
[const unsigned int end = 0 ]]])

display_records displays a range of records from record number start to record number end. Both of these arguments have default values. The default for start is 1 and the default for end is 0.

If end = 0, either because it was passed by the caller explicitly, or because the default is being used, then display_records starts with record start and continues until display_single_record returns unsuccessfully (return value 1).

Otherwise, if end > 0 and end < start, then a warning is issued, end is set to 0, and display_records proceeds as above.

Otherwise, display_records starts displaying records from record number start, and continues up to and including record number end. It will continue to call display_single_record, even if the latter returns unsuccessfully for some record number. This is because there may be gaps in the sequence of record numbers because of deletions, or for some other reason. This isn't likely, but it is possible.

These rules imply that a call to display_records with no arguments will display all of the records in the PICA_DB database.

31.22 Physical_Descriptions

The following PICA categories used all used for the physical descriptions of resources. Unfortunately, some are used for more than one physical feature, so they are ambiguous. For example, the English description of the PICA3 4060 category is “Size or Range, Specification of Material, Technical System”. In addition, these categories all have only a single field, namely “Text”, so that unlike other categories, the ambiguity cannot be resolved by the use of fields.

PICA3 PICA+
4060 034D
4061 034M
4062 034I
4063 034K

!! TODO: Add cross-references and index entries!

The number of different features that can be described using these classifications is large enough to make it impracticable to have a column for each one in the Physical_Descriptions table. Due to the above-mentioned ambiguity, it would also be impossible for a program to determine which column would be appropriate for a given entry. The Physical_Descriptions table therefore includes a pica_category_id column, so that users may at least see how the data was categorized in the PICA source.

With respect to these categories, the pica_field_id in the Physical_Descriptions table is redundant. I have added it in case other categories are used for physical descriptions.

31.30 Subject_Types

This table stores information about the classes of subjects specified in the “Indikator/Indicator” field of Pica+ 041A/Pica3 800; 5100–5199. This is the S field in Pica+ 041A. See 041A Subject, 041A Fields, and 800; 5100–5199 Subject.

The Subject_Types table is referenced by the ODBC class Subject_Types. See Subject_Types (ODBC Class).

The indicator column (see below) must contain one of the characters used as values in this field.

The following table shows these values. Some are only used with Pica3 5100–5199.
