Does anyone know of any other vocabulary popularly used to describe projects besides DOAP and Project Vocabulary.
If you are innovating in your project (which I bet you are ;)), then see below:
The first vocabulary we produced did assert equations between FOAF projects and innovation, but we dropped these due to domain/range issues on certain FOAF project terms.
However it is strongly compatible with FOAF Agent, Groups and People since we use these terms as substitutes for Collaboration/Collaborator concepts.
Baetle Ontology from Henry Story captures some aspects of project related to issue tracking. It links to DOAP ontology.
If you need funding in your project (which I bet you do) and it's an academic project, then try the Academic Research Project Funding Ontology (ARPFO) by Ben O'Steen.
