Simply use anys or strings to identify for now. Allows an external service to manage identity separate from Map service. Barber of NCGR notes that Baron's EDS proposal will address their needs. NCGR notes need to integrate Maps submission with Sequence Analysis submission. Noted earlier in our discussion, will try to address integration as much as possible at this time.
Comment also applauds involvement from so many groups in the submission.
Some doubts about scalability to complex queries. Nothing to preclude this. Query supports recursion depth. Would like additional information or use cases for this requirement. Also, consider role of ontologies in submission.
