We have collected Identify, ListSets, ListMetadataFormats, and sample records from all of the OAI compliant repositories we could find from various sources, added the data to a database, indexed them, and made them searchable. We have also created several reports from the data. This system is driven entirely from database queries against our database, and not from live queries to the OAI repositories. Therefore, at any given time the data will be out-of-date by some period of time. The data in our database will be periodically refreshed from the original OAI repositories, plus new repositories will be added as they are found. For an XML report of all the repositories from which we have data, access our Friends List. This collection is also harvestable via the OAI protocol; the baseURL is http://gita.grainger.uiuc.edu/registry/px/oai.asp.
For anyone wanting to track the latest changes to this registry, an RDF Site Summary (RSS) is found at http://gita.grainger.uiuc.edu/registry/rss.asp. This RSS will list the repositories which have been added or modified in this registry in the past 30 days. Newly added repositories will have [NEW] prepended to their title for easy identification.
There is also an SRU (Search and Retrieve URL Service) available for searching the registry. The base URL for the service is http://gita.grainger.uiuc.edu/registry/sru/sru.asp. SRU allows client applications to perform basic searches against the registry. The service supports a subset of the CQL (Common Query Language), allowing either the repository name, repository base URL, repository identifier, or the full text of various OAI responses to be searched. Booleans are not yet supported. Records can be retrieved in either Dublin Core or ZeeRex formats. Some sample queries following:
