基于开源PostgreSQL ORDBMS的异构数据档案元数据综合查询接口
Comprehensive Metadata Query Interface for Heterogeneous Data Archives Based on Open Source PostgreSQL ORDBMS
摘要：
我们使用PostgreSQL DBMS存储XML元数据，由IVOA特征数据模型描述。PostgreSQL中的初始XML类型支持最近已经实现。我们大量使用此功能，以提供对表征元数据树的全面搜索。我们建立了一个特征化元数据查询服务的原型，实现了两种访问方法：（1）基于HTTP-GET/POST的接口实现了几乎直接将查询参数名翻译成XML序列化中的数据模型元素的后缀;（2）基于Web服务的接口接收XQuery，也直接翻译成后缀。这项服务将用于ASPID-SR档案，其中包含俄罗斯6米望远镜获得的科学可用数据。
英文摘要：
We use PostgreSQL DBMS for storing XML metadata, described by the IVOA Characterisation Data Model. Initial XML type support in the PostgreSQL has recently been implemented. We make heavy use of this feature in order to provide comprehensive search over Characterisation metadata tree. We built a prototype of the Characterisation metadata query service, implementing two access methods: (1) HTTP-GET/POST based interface implements almost direct translation of the query parameter name into XPath of the data model element in the XML serialisation; (2) Web-Service based interface to receive XQuery which is also directly translated into XPath. This service will be used in the ASPID-SR archive, containing science-ready data obtained with the Russian 6-m telescope.
