Lessons Learned Using VOResource v0.9
- This document describes in part the changes to be recommended for VOResource v0.10

Proposed VOResource V0.10 XML Schema and Extensions

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

Ratified decision of previous videocon to switch from substitution group based inheritance to type-based
Types are defined in RM
Documents are defined in RI
Logical-id will be defined via a second relationship (rather than via direct attribute)
Level of hierarchy will be as in RM v1.01 (except as resolved otherwise here)
Service types as a sub-class of Resource (rather than extending Capability)
Organisation type will be defined in the base VOResource definitions
Referred resources will be via xsi:type of RegisteredResourceType and UnregisteredResourceType
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

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
The metadata describing a registry will include a flag indicating whether it is a full or publising registry.
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
An IVOA Registry must support the Keyword Search as specified in the RI document
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

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