---++ Meeting outcomes
---+++ Resolutions
(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
   1 Types are defined in RM <br> Documents are defined in RI
   1 Logical-id will be defined via a second relationship (rather than via direct attribute)
   1 Level of hierarchy will be as in RM v1.01 (except as resolved otherwise here)
   1 Service types as a sub-class of Resource (rather than extending Capability)
   1 Organisation type will be defined in the base VOResource definitions
   1 <span style="text-decoration: line-through">Referred resources will be via xsi:type of _RegisteredResourceType_ and _UnregisteredResourceType_ </span>
   1 <span style="text-decoration: line-through">The element name for a referred resource identifier will be *ResourceRef* (instead of Identifier which was confusing) </span>

<span style="font-size: 80%">Note: Decisions on referred resources were reversed in Session 3</span>

---++++ 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
   1 The metadata describing a registry will include a flag indicating whether it is a _full_ or _publising_ registry.
   1 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
   1 An IVOA Registry *must* support the Keyword Search as specified in the RI document
   1 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
   1 Will promote v1.1 of Identifier spec to PR status thence to REC
   1 Implement owned/managed authorityID to cater for Publishing/Full registries

---+++ Actions / Timetable

| *Action* | *Who* | *When* |
| Revise schema definition v0.10 | Ray | _done_ |
