I've just put up the April edition of the Ada project catalog. Thank you all very much for the numerous additions and corrections; I think I've processed them all. I've also added internal links to make the catalog easier to navigate.
As you can see from the description below, I've decided to stay with my original concept. I'm cataloging applications for as many domains as possible - with no preference for size, open-source vs. proprietary, military vs. non-military, etc. On the other hand, tools for use by software developers are catalogued quite well elsewhere and I do not wish to duplicate those efforts.
Thanks again for your continued assistance!
"Who's Using Ada: Real-World Projects Powered by the Ada Programming Language"
What this is: This is the most comprehensive known catalog of systems, in operation or under active development, in which Ada is used at least to a significant degree.
What this is not: This is not a catalog of Ada-oriented software tools, libraries, bindings, and the like. The emphasis here is on applications designed for some end-user community, not for software developers. There are many, many Ada developer artifacts, and several excellent developer-oriented catalogs, including the Ada Information Clearinghouse, AdaPower, and (especially for open-source projects) the Ada section of SourceForge; these catalogs are all actively maintained and it is unnecessary and undesirable for me to duplicate those efforts.
The Ada community has much to gain from a comprehensive list like this; I need your help in maintaining it! Please e-mail additions or corrections to me -- including web links for the unlinked projects -- at the above address. I respect the confidentiality of my sources.
