An application that queries or consumes descriptions of VO
resources must be able to recognize a resource's support for
standard IVOA protocols. This specification describes how to
describe a service that supports any of the four fundamental
data access protocols--Simple Cone Search (SCS), Simple Image
Access (SIA), Simple Spectral Access (SSA), Simple Line Access
(SLA)--using the VOResource XML encoding standard. A key part
of this specification is the set of VOResource XML extension
schemas that define new metadata that are specific to those
protocols. This document describes in particular rules for
describing such services within the context of IVOA Registries
and data discovery as well as the VO Standard Interface (VOSI)
and service self-description. In particular, this document
spells out the essential mark-up needed to identify support
for a standard protocol and the base URL required to access
the interface that supports that protocol.

Description:
This document describes an XML encoding standard for IVOA
Resource Metadata, referred to as VOResource. This schema is
primarily intended to support interoperable registries used
for discovering resources; however, any application that needs
to describe resources may use this schema. In this document,
we define the types and elements that make up the schema as
representations of metadata terms defined in the IVOA
standard, Resource Metadata for the Virtual Observatory
[Hanisch et al. 2004]. We also describe the general model for
the schema and explain how it may be extended to add new
metadata terms and describe more specific types of resources.
