The project is to extend [mod_dav] to implement [CalDAV]. I have included a PDF file that gives a good overview.
It must be written in C, autoconf and libtool. You may use any open source code in compliance with their licenses. The ability to run on Windows as mod_dav presently does would be nice. User guide and installation documenation is required. You may propose a schedule for deliverables.
You be given credit as the author. We will maintain the copyright. The license will be a modified Apache license as required by the mod_dav license.
1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables):
a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment.
b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request.
3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement).
Windows would be good, but not required.
