Meeting outcomes


(I would ask people who actually understand what was decided in the meeting to flesh out the following: TonyLinde )

Session 1

  1. Ratified decision of previous videocon to switch from substitution group based inheritance to type-based
  2. Types are defined in RM
    Documents are defined in RI
  3. Logical-id will be defined via a second relationship (rather than via direct attribute)
  4. Level of hierarchy will be as in RM v1.01 (except as resolved otherwise here)
  5. Service types as a sub-class of Resource (rather than extending Capability)
  6. Organisation type will be defined in the base VOResource definitions
  7. Referred resources will be via xsi:type of RegisteredResourceType and UnregisteredResourceType
  8. The element name for a referred resource identifier will be ResourceRef (instead of Identifier which was confusing)

Note: Decisions on referred resources were reversed in Session 3

Session 2

  1. An IVOA Registry must support OAI-PMH protocol for harvesting via HTTP GET, returning at least oai_dc and ivo_vor metadata formats using standard data criteria
  2. The metadata describing a registry will include a flag indicating whether it is a full or publising registry.
  3. The standard IVOA Registry Harvesting specification will be web service-based and will conform to the full OAI-PMH specification: details will be worked out on the mailing list
  4. An IVOA Registry must support the Keyword Search as specified in the RI document
  5. An IVOA Registry must support a Full Query (interface tbd) using the WHERE clause of the ADQL schema with fields specified using non-namespaced XPath directives (simple, ie no [...] options), and returning full resource entries

Session 3

  1. Reversed Session 1 decisions re Referred resources
    • Referral will be via ivo-id attribute
  2. Will promote v1.1 of Identifier spec to PR status thence to REC
  3. Implement owned/managed authorityID to cater for Publishing/Full registries
