Subsequent to the day-long session in Woods Hole, where I presented a candidate data annotation ontology. The FilteredPush (FP2) project met several times with Paulo Ciccerese and discussed whether AO Annotation Ontology would work for data annotation as well as document annotation and still meet therequirements met by the ontology I presented... Paolo thinks yes, with only the subclassing of what AO calls a Selector. From a lot of experience with XML, I have a natural skepticism that modeling documents and modeling data are the same thing, but part of my ontology work in the FP2 project is to try to use AO, and I have been working on Paolo's challenge to model our use cases with it. Curiously(?), one simple one needs no Selector at all and I can't tell yet whether the extensions I had to make to AO got simpler or more complex because of that. When I get a little farther, I'll report on it here. -- BobMorris - 15 Jan 2011

The Filtered Push project had another meeting with Paulo Ciccerese to discuss two examples of Biodiversity data annotations I coded with a small extension of AO. We now believe that AO can be extended to the model I presented at Woods Hole and expect more collaboration with Paulo. Since the W3 Incubation Group that gave rise to AO for documents is at the end of its life as an Incubation Group, Paulo is setting up a proposal to W3C? for a full working group to proceed toward a W3C? Recommendation, including extensions for data annotation.

Examples of annotations of biodiversity data expressed in the data extension of AO are illustrated at: http://etaxonomy.org/mw/AOD_Extension_of_AO_for_Data#Examples. -- PaulJMorris - 06 Jul 2011
