Federated Search

This is the starting point / index for resources related to the Federated Search working group.

There is a rather comprehensive discussion paper under: FederatedSearch/docs/FederatedSearch.docx​
that tries to collect all the previous information, and has been circulated and reviewed within the group in the period Feb - May 2011. However this document is almost 50 pages, with many comments and open questions yet and - being a Word-document - difficult to edit collaboratively, thus in the next phase (starting with the Nijmegen workshop 2011-05-09), we want to transfer parts of this document into (separate) wiki-pages, to then continue developing this material collaboratively towards a more concise specification.

Following are the main sections:

FCS-spec

Specification of the interface that Content Provider willing to join the federated search have to implement. This builds upon the SRU/CQL protocol, but concentrates mainly on the specific agreements on top of the protocol.

Query Language

a separate page should elaborate on the query language (CQL) as provided by the protocol, plus the discussed extensions. There is an old page to this topic (QueryLanguage), but it has to be reviewed and updated.

FCS-Aggregator

Specification and implementation-related notes for the aggregating (metasearching) component/service.

RepositoryRegistry

a separate page should be devoted to the issue of announcing the Repositories and their capabilities (Feature Matrix)

EDC-Workbench

This page shall collect ideas about the web application (web user interface), that allows the user to interact with the FederatedSearch and other related components, with the core use case being a combined metadata and content query. There is already an external wiki-page about this topic (​vronk.net EDC-Workbench). It is slightly outdated, but a good starting point.
