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.
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.
This document defines a set of metadata that can be used to describe graphical images (e.g. JPEG, GIF, etc.) used for astronomy public outreach. It was developed via the IAU Virtual Astronomy Multimedia Project (VAMP) with input from the broader astronomical outreach community. The AstroVisualiztionMetadata page covers discussion of this document as a candidate IVOA standard.
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.
A working draft of a document defining the extension schemas for describing standards (including the ability to define IVORN-identifiable properties) is under development at VOStandard.
A working draft of a document defining the extension schemas for describing SIA (schema), SSA (schema), and ConeSearch (schema) is under development at RegSimpleDAL.
A working draft of a document defining the extension schemas for describing applications is under development at RegDMApplications.
The VOResource has been designed to allow new metadata to be defined as an extension on the core. The VOResource specification recommends how to create extension schemas. Additional information about extending the VOResource schema, consult the VOResource page.
