As for me, I will be participating in the one that is listed last :-), with Amanda Vizedom. But, I have to warn you that the name is a bit overwhelming ... "An ontological catalogue of ontology and metadata vocabulary characteristics relevant to suitability for semantic web and big data applications". Whew!
Really, it is about creating simple sets of concepts (i.e., a "catalog") to characterize vocabularies, models and ontologies. The catalog will be created in GitHub as a publicly available, open-source ontology (collaboratively developed and extensible over time). This Hackathon project is all about the problem of reuse ... You can't reuse something unless you understand not only what its contents are, but the intent behind creating the thing, how it was designed to be used, etc. This is summarized in the following quote from the Summit's Track A synthesis:
Documentation must include the basic details of the semantics, but also the range of conditions, contexts and intended purposes for which the content was developed. It was recommended that standard metadata for reuse be defined and complete exemplars provided.If you are interested in participating, the kickoff is 10am EDT tomorrow using Google Hangout. Working materials are available at https://github.com/ajvizedom/vocref. If you are interested, have a look at the GitHub site, "watch" the repository, and become a contributor by adding yourself to the team roster on the project's wiki page.
Looking forward to working with you tomorrow!
