Resource Metadata

Standard Specifications

The standards for metadata used to describe resources in the VO come in two forms: prose documents that define the metadata concepts and XML Schemas used to encode them.

Metadata Definition Documents

IVOA Recommendation

"Resource Metadata for the Virtual Observatory" v1.01
Robert Hanisch, Ed.

This document (euphemistically referred to as "RM") defines standard metadata concepts that describe resources, independent of any particular encoding format. It also describe the general resource model upon which the concepts are based.

This document is intended primarily for developers of new standards for encoding resource metadata. The latest work on the RM standard is tracked via the RWP03Specs page.

XML Schemas

IVOA Working Draft

VOResource v0.9 core schema and standard extensions
RayPlante, Editor

VOResource in general refers to a set of XML Schemas that includes a core schema (VOResource-v__X.X__.xsd) based on the RM Recommendation and a set of standard extension schemas that define particular types of resources.

These schemas are intended for use by VO XML-based applications. In particular, these schemas are used for supporting interoperable communication with resource registries.

The latest work on the VOResource schemas is tracked via the RWP03Specs page. This includes the latest emerging drafts:
