VOResource v0.9 and its Standard Extensions

VOResource, in general, refers to a family of schemas that includes the core schema (VOResource-v0.9) and a set of standard extensions.

New as of 18 Nov. 2003. Developers have identified a few mistakes in the schemas; as a result, the following files have been updated:

Be sure to download these updated versions (or download the complete set from the tar-ball/zip-file links below).

New as of 5 Nov. 2003. Updated WD versions of the schema are now officially available. Developers should be sure to download the latest versions from the table below (or all of them together: tar-file, zip-file)--even the version number appears unchanged--as the namespace names have all been updated. These are the schemas to be used for January 2004 demos.

The schemas are:

Schema Description Versions Documentation
requires VOResourceRelType-v0.2.xsd and VOResourceRelType.xsd which handle extensible relationships
core resource metadata 0.9, 0.8.3, 0.8.2, 0.8.1 (see also older deprecated versions) VOMDoc

(XMLSpy   xs3p)

VOCommunity-v0.2.xsd extensions for describing organizations and projects (formerly VOOrg) 0.2, 0.1, VOOrg-v0.1 VOMDoc

(XMLSpy   xs3p)

requires VODataServiceCoverage.xsd and VODataServiceCoverage-v0.2.xsd which contain temporary coverage metadata
extensions for describing data collections and services 0.4, 0.3, 0.2, 0.1 VOMDoc

(XMLSpy   xs3p)

VORegistry-v0.2.xsd extensions for describing registries 0.2, 0.1 VOMDoc

(XMLSpy   xs3p)

The following two extensions are examples of extensions that define two standard tabular sky services. They include the elements necessary for decribing the tables returned by the services (using VOTable tags). These are included for indicative purposes only.

ConeSearch-v0.2.xsd extension for a Cone Search Service 0.2, 0.1 VOMDoc

(XMLSpy   xs3p)

SIA-v0.6.xsd extension for a Simple Image Access Service 0.6, 0.5 VOMDoc

(XMLSpy,   xs3p)

Download all schemas in one go; two versions are available below. When these packages are unpacked, all files will be put in the current directory.

VOResource-v0.9 (tar.gzzip)
the official schemas from the table above.
VOResource-v0.9-local (tar.gzzip)
the official schemas with "schemaLocation" set to look for imports on local disk. This version enables a verifier to look for schemas in the current directory instead from the IVOA site. Use this version when developing off-line or with tools that have trouble finding imported schemas.

More supporting material is coming soon!
