5. Session 1: Registry Standards for Extensions StandardsRegExt ready for TCG review (Ray Plante) –Open for comments until end of next week –Cool feature... this allows standards definitions to add key terms related to the standard without required controlled vocabulary –Compliant Standards will be registered in RofR (central Registry of Registries repository) SimpleDALRegExt for describing SIA, SCS, SSA, and now SLA too!(Ray Plante) working draft in RWG review period needs some additional work for handling standards versioning TAPRegExt (Markus Demleitner) working draft near stable human readable elements for the content of TAP capability productive discussion details,output format and upload methods 20 May 2011IVOA Interoperability Meeting -- Naples

6. Session 2: Service Validation Two viable full registry validators presented! Live demo for DAL registry validator (R. Savalle, P. Le Sidaner) Paris Observatory –Uptime of services, interactive and scriptable interfaces to running this system VAO Service Validators in practice (T. Dower) –validators usage: service deployment, publication, and polling –working on system for setting validationLevels in resources VODataService - take-up/pep talk (M. Demleitner) –Data Collections scenarios (GAVO) lensed quasars –Needs TAP to deliver data models which is supported in VODataService, use of VOSI to take advantage of table setup 20 May 2011IVOA Interoperability Meeting -- Naples

7. Registry Apps and Future Directions Rekindled discussion on AppRegExt (G. Greene) –need to establish use cases and requirements –update earlier model (P. Harrison) for new framework models such as App Store, Services that don't always fit neatly into standards, FASE REST interface for the Registry –clearly interest in more simplified model than the current SOAP interface –adapt the Registry Interface to the BWSP standard –NVO implementation as example IVOA level effort cross compare Validator service Results –concern on maintenance of our primary registries –need TAP validators! 20 May 2011IVOA Interoperability Meeting -- Naples
