3. Definitions Definition: The IVOA Registry will allow an astronomer to be able to locate, get details of, and make use of, any resource located anywhere in the IVO space, i.e. in any Virtual Observatory. The IVOA will define the protocols and standards whereby different registry services are able to interoperate and thereby realise this goal. Publishing Registry – A Registry that holds xml resources managed by your authority id’s. And is harvestable by Full Registries. Does not require a Query interface, but typically has one. Full Registry - A Registry that holds all xml Resources. Has a Query and a Harvest Interface.

9. Future Work Harvesting Services Not just Registries. ValidationLevel in the schema but not handled in the Astrogrid Registry. Xforms at the Service level. Could that be the END? Just Maybe.
