I have a couple related questions, on publishing a new RDF vocabulary - 1) What is the correct procedure for subclassing an existing vocabulary that I don't maintain? For example, in the annotea schema, http://www.w3.org/2000/10/annotation-ns "The 'related' property is expected to be subclassed by more specific relationships." - and I'd like to create some subclasses, such as isLocalizationOf isPersonalizationOf isExampleOf implements followsUpOn corroboratedBy contradictedBy But, I'm not sure how to go about subclassing a property if I don't maintain the namespace? I'd rather build on the existing wherever possible, it would seem just much better practice, no? 2) I know I've asked before, but do we have anything equivalent to http://Freshmeat.net for rating, commenting on, discovering by searching human readable text, etc on vocabularies? Mike Hausenblas gave me a good list of sites - [1] http://olp.dfki.de/ontoselect/ [2] http://www.schemaweb.info/ [3] http://www.sindice.com/ [4] http://pingthesemanticweb.com/ [5] http://swoogle.umbc.edu/ [6] http://esw.w3.org/topic/TaskForces/CommunityProjects/LinkingOpenData/Sem anticWebSearchEngines and I've spent several hours searching around on them, but it seems to me that for an initial search of the type 'Has anyone already done what I'm thinking of?', a human-annotated and human-ranked list of vocabularies would be more useful. Anyway after my bit of clumsy searching around, I didn't find what I wanted - a vocabulary for grassroots annotations of URLs - but later browsing on the microformats site I came across TDL, the Thread Description Language that has respondsTo, respondsPositivelyTo and respondsNegativelyTo. I wouldn't have guessed those terms, but they make sense after seeing them. Still, I'd like to know how widely used they are before adopting for my purposes. I guess what I'm getting at, is I see a need for human-readable comments, ratings, and discussion of vocabularies organized by category, and I haven't yet found it. Does anyone else feel the same, or did I just miss something when looking around? 3) While I'm bothering folks, does anyone else have a suggestion for a grassroots annotation vocab in additon to these three I'm looking at now? I am planning to use Danny Ayers and Tom Heath's Review vocabulary at http://danja.talis.com/xmlns/rev_2007-11-09/index.html Annotea http://www.w3.org/2000/10/annotation-ns# and possibly TDL http://www.schemaweb.info/schema/SchemaDetails.aspx?id=199 The idea is to record annotations and assertions that may not be reviews or ratings, and to let users make assertions about two URI's they may not have created. May need terms such as (listed above) isLocalizationOf isPersonalizationOf isExampleOf implements hasFollowUp corroboratedBy contradictedBy and also perhaps isResponsibleFor inspiredBy hasAnecdotalEvidence / hasPersonalAccount hasFirsthandAccount hasSecondhandAccount which brings up another thing - best practices for reification especially when making non-authoritative assertions about two things I don't own. But that's another email.
