IVOA建议:SimpleDALRegExt:描述简单数据访问服务

IVOA Recommendation: SimpleDALRegExt: Describing Simple Data Access Services

Raymond Plante, Editor Jesus Delago, Paul Harrison, Doug Tody, the IVOA Registry Working Group

摘要:

查询或使用VO资源描述的应用程序必须能够识别资源对标准IVOA协议的支持。本规范描述了如何使用VOResource XML编码标准来描述支持四种基本数据访问协议(简单锥形搜索(SCS)、简单图像访问(SIA)、简单频谱访问(SSA)、简单线路访问(SLA))中任何一种的服务。该规范的一个关键部分是一组VOResourceXML扩展模式,这些模式定义了特定于这些协议的新元数据。本文档特别描述了在IVOA注册表和数据发现以及VO标准接口(VOSI)和服务自描述的上下文中描述此类服务的规则。特别是,本文档详细说明了标识对标准协议的支持所需的基本标记,以及访问支持该协议的接口所需的基本URL。

英文摘要:

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 markup needed to identify support for a standard protocol and the base URL required to access the interface that supports that protocol.
