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
typed 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 rules for describing such services
within the context of IVOA Registries and data discovery as well as the VO
Support Interfaces (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.
