Open Tasks for EDMA

There is still a lot of work to do on EDMA. The system needs a lot of testing in order to correct bugs and extend facilities. We now list some of the tasks to be done. If you are interested in collaboration you can contact us at dmartin@tsc.uvigo.es.

Main System

This section covers tasks in the main EDMA system. This is being worked on mainly by David Martínez Oliveira, who wrote it.

• On-demand Interface Load: The current version loads all the interfaces when the system starts up. Future versions will load interface information only when objects are created.
• Error Management: This includes Multilanguage error message support and the full specification of the EMI subsystem.
• Dynamic Object-Orientation: This includes a more suitable interface for managing dynamical inheritance relationships, and SIU subsystem integration with the object-oriented facilities (SIU PROXIES of level 3). The final task in this area will be the specification of what we call Loosely Coupled Object Oriented Systems (LCOOS).
• Dynamic Invocation Interface to allow some languages to use EDMA
• New primitives such as clone, shallow_clone,...

Porting

EDMA works on GNU/Linux systems as well as Windows 95 systems. We would like to port it to systems such as OS/2 and other Unix flavors. Any help towards this will be welcome.

Sergio Costas is working on porting EDMA to OS/2

Interpreted Systems

There are three main projects here:

• GUILIAN: This project's goal is to create an interface to the GNU Guile extension language. This would allow Guile applications to use EDMA facilities and EDMA applications to use classes written in Guile.
• JANE: The same as GUILIAN but for the Java language. There is a simple and still incomplete version for Windows 95.
• EVELIN: This will be a C-like interpreted language with special constructors to use EDMA. The project includes an interpreter, a byte-code compiler and a virtual machine.

Some tasks are oriented towards develop SIU PROXIES for using other technologies.

Interpreted systems fall in this section too.

• FAYE: EDMA remote object facilities. This system requires full pack/unpack code as well as bi-directional implementation, that is, you can use a remote object from your local system, but this remote object can't see local objects.
• SHARON and PENNY: This system will provided shared object and persistent object facilities for EDMA. There is no current development on this.
• CONNIE: This SIU extension will integrate CORBA with EDMA, allowing you to use CORBA objects from an EDMA application or EDMA objects from a CORBA application. There is no current development on this.

This covers the development of EDMA classes for programmers' use.

• PORTABLE/1: This will be a set of low level classes which provide a portable interface to machines and operating systems, so as to make EDMA source code portable.
• IRINA: This will be a set of classes for Graphical User Interface development. The goal is to develop a powerful widget set that is fully customizable, that is, to bring EDMA dynamic facilities to GUIs.
