我们描述了简单数字图书馆互操作协议(SDLIP),它允许客户端以统一的语法查询信息源。该协议是斯坦福大学、加州大学伯克利分校、圣巴巴拉分校、圣地亚哥超级计算机中心和加州数字图书馆合作开发的。除了介绍协议之外,我们还描述了一些设计选择,并将它们与其他搜索中间件方法中所做的选择进行比较。该协议允许有状态和无状态操作,支持多种查询语言,并定义了一个简单的基于 XML 的返回格式。 SDLIP 中包含的默认查询语言遵循不断发展的 IETF DASL“basicsearch”。这是一种 XML 编码语言,让人想起 SQL,但经过调整以在全文环境中使用。 SDLIP 可以与 CORBA 或 HTTP 一起使用。
We describe our Simple Digital Library Interoperability Protocol (SDLIP), which allows clients to query information sources in a uniform syntax. The protocol was developed in a collaboration between Stanford, the Universities of California at Berkeley, and Santa Barbara, the San Diego Supercomputer Center, and the California Digital Library. In addition to introducing the protocol, we describe several of our design choices, and compare them with the choices made in other search middleware approaches. The protocol allows for both stateful and stateless operation, supports multiple query languages, and defines a simple XML-based return format. A default query language that is included in SDLIP follows the evolving IETF DASL 'basicsearch'. This is an XML-encoded language reminiscent of SQL, but adjusted for use in full-text environments. SDLIP can be used with CORBA or HTTP.
