C H A I M S: Compiling High-level Access Interfaces for Multi-site Software Towards the Science of Component Engineering

Ongoing Work Winter 1998

Minimal infrastructure

The most urgent goal for the quater winter 1998 is to get a minimal infrastructure running which takes a CHAIMS-megaprogram, compiles it and runs it (only CORBA, blobs are still strings). For this, the following things need to be finished:

• Wrapper:
  - adding missing parts, code of Steve (Pankaj, Catherine)
  - consolidating interface with output of compiler (Woody, Pankaj)

• Compiler:
  - clean up code (Woody, Catherine)
  - output to files, repository (Woody)

• Integration and Test: maybe with mathmegamodule (Pankaj, Woody, Catherine)

Basic infrastructure and prototype/demo

A further goal of winter/spring 1998 is to have a basic infrastructure that allows us to experiment with further features of the CHAIMS-language like estimation and optimisation. This basic infrastructure includes the ability to mix megaprograms that speak different protocols (CORBA, DCE, DCOM, RMI) and the encoding of blobs as ASN.1 data. Furthermore we will need a demo by the end of June 1998.

• Wrapper:
  - ASN.1 converter (Hao)
  - wrappers, bridge or compiler enhancements for RMI (Catherine, Mehul)

• Compiler:
  - mixing CORBA and DCE (Woody)

• I/O-megamodule:
  - displaying ASN.1 data (Kazuki, Hao, Dorothea)
  - entering data (???)

• Demo: - ???

Other activities

• Paper for IEEE Software (Dorothea, Catherine), deadline Febr,15
