Below is earlier versions of VOResource and supporting information that are deprecated by the proposal above. The 2nd schema below holds metadata (roughly) specific to the SIA protocol.

• VOResource.xsd: Versions: 0.1

• VOStdService.xsd: Versions: 0.1, 0.2, 0.3

To help folks interpret these schemas, I've prepared some additional resources:

• An overview document that explains the major components and structure of the schemas; you may find the XMLSpy diagrams particularly helpful. It also gives a summary of the overall approach used to define metadata within XML Schema.
• A sample XML instance document shows how to describe an organization, a data collection, and services using this schema. It shows how metadata from different schemas can be combined into a single document. (See overview document for more description.)
• A Metadata Dictionary generated automatically directly from the XSD file using an XSL stylesheet.
