Two great frameworks. One provides seamless extensions of Foundation and AppKit. The other has everything you need to deal with mail and news messages. Both are released under a BSD style Open Source license.

The origins of the EDCommon und EDMessage frameworks date back to 1997 and the original NeXT implementation of the OpenStep standard. Most of their components have been thoroughly tested and refined through years of use in Open Source as well as in commercial projects. EDCommon also has full Apple-style reference documentation for all classes and other APIs.

EDCommon EDMessage

The EDCommon framework extends Foundation and AppKit in a natural way. It contains common methods you always need, like removing whitespace around a string, special collection classes such as stack or object pair, an object-oriented API for socket programming, some widgets, a parser for markup languages and other nifty stuff.

The EDMessage framework contains classes to parse and create Internet messages with MIME extensions. It also contains a ready-to-use email client class that suports TLS, authentication, and a few other useful extensions.

Finally, the license in the source files stipulates that if you use the frameworks you have to mention the authors of the frameworks at an appropriate place in your application/documentation. This would be Erik Dörnenburg for all frameworks and, additionally, Axel Katerbau for the EDMessage framework. If you feel like it display one of the logos and/or a link to Mulle Kybernetik. This is not required, though.
