SRU/CQL Standardization in OASIS

OASIS Search Web Services Technical Committee

July 2009 Drafts | 2008 Committee Drafts 

TC Page  | Call for Participation  | Join the TC | Comment | DLIB Article, January 2009

The OASIS Search Web Services Technical Committee has drafted an Abstract Protocol Definition (APD - see document 1 in the table) providing the framework for the definition of "Application Protocol Bindings".  These bindings may be static or dynamic.  A static binding is a human-readable document, essentially a profile.  A dynamic binding is a machine-readable description of a server, written in a description language that the Committee is also developing (described in  Annex B of the APD).

The premise behind dynamic bindings is that any search engine, even one that existed prior to development of the standard, need only to provide a dynamic binding -  a self-description. It need make no other changes in order to be accessible. A client will be able to access any search engine that provides a description, if only it implements the capability to read and interpret the description and use it to formulate a request (including a query) and interpret the response.

Committee drafts include  bindings for  SRU 1.2 (2)  and openSearch (5) as well as a specification of CQL 1.2 (4 ).

The current phase of work is the development of an SRU 2.0 binding, CQL 2.0, Explain, and Scan.
