4. Sakaibrary Agreements It’s common for Repository implementations to make use of Out Of Band Agreements to describe: The type of Repository Examples: Metasearch, DSpace Ways that data can be found Examples: Keyword search, by content type The nature of the data available Examples: Date, author, URL

5. Sakaibrary Agreements Additional agreements were suggested by our use of asynchronous meta-search technology. We need to exchange information regarding: Metasearch access Location and Authorization details Display properties Page size, sorting Search status Global details: total hits, total records fetched, etc.

6. Sakaibrary Agreements Additional agreements (continued) Search Syntax We support only one type of search. Search criteria are provided using CQL (the Common Query Language): Well known syntax (defined for use with SRU/SRW) Expressive (a superset of the capabilities currently available via our meta-search technologies) Error handling Java Exceptions are used to signal specific types of problems: No more results available Meta-search session timeout End of merged record set
