Apologies that this has been so delayed. Use Case: A teacher wants to find some learning materials for his class. He is using a recommended website providing descriptions of learning materials and does a search, chosing the general subject area, student learning level and giving some keywords. The results include materials returned from multiple learning repositories, where the subject and learning levels have been matched across multiple educational metadata vocabularies. Motivates: Design Object 4.2 Provenance http://www.w3.org/2001/sw/DataAccess/UseCases.html#d4.2 Design Object 4.5 Aggregate Query http://www.w3.org/2001/sw/DataAccess/UseCases.html#d4.5 I think 4.2 probably should be a (candidate) requirement, not an objective. At least if it is replaced with something more specific such as enabling the returning of the Source URI of the document that contained the trible. it probably motivates a new potential requirement: Free text searching of literals It should be possible to perform free text searches of RDF literals in the query. Free text search at the minimum means allowing substring searches of literals or could include more powerful matches such as regexs or full-blown matches with stemming etc. Dave
