In that case, I've got a few more that I'll be posting to this list over the coming weeks. > From the point of view of the HTML5 effort, what is needed is use cases, > scenarios, and requirements, that don't in any way imply a particular > solution, as in the list I posted, so that solutions can be evaluated. Then, I hope this helps... I'm trying to keep the same format that you posted: ======================================================================== Validation of Expressed Micro-data USE CASE: Expose machine-readable documentation of micro-data vocabularies so generalized validators and authoring tools can be written. SCENARIOS: * Echo would like to write a generalized software tool to help page authors express micro-data. One of the features that she would like to include is one that displays authoring information, such as vocabulary term description, type information, range information, and other vocabulary term attributes in-line so that authors have a better understanding of the vocabularies that they're using. * Thundercleese would like to ensure that his indexing software only stores type-valid data. Part of the mechanism that he uses to check the incoming micro-data stream is type information that is embedded in the vocabularies that he uses. * Sephiroth, harvester of souls, would like to provide warnings to the authors that use his vocabulary that certain vocabulary terms are experimental and may never become stable. REQUIREMENTS: * There should be a definitive location for vocabularies. * It should be possible for vocabularies to describe other vocabularies. * Originating vocabulary documents should be discoverable. * Machine-readable vocabulary information shouldn't be on a separate page than the human-readable explanation. ======================================================================== More on this particular use case can be found here: http://rdfa.info/wiki/rdfa-use-cases#Publishing_an_RDF_Vocabulary_and_Validating_Usage -- manu -- Manu Sporny President/CEO - Digital Bazaar, Inc. blog: A Collaborative Distribution Model for Music http://blog.digitalbazaar.com/2009/04/04/collaborative-music-model/
