+= OAI - Open Archives Initiative =
+The open archive initiative deals with the dissemination of metadata
+and connection of electronic repositories. An institution publishes
+its catalogue via OAI-PMH so that others can search it. On the one
+hand there are providers who provide the metadata of what they have in
+their repository, on the other hand are the harvesters who provide a
+search interface to metadata repositories.
+
+== Providers ==
+Although you can use several types of metadata, [http://www.openarchives.org/OAI/2.0/guidelines-repository.htm#MinimalImplementation-DC unqualified Dublin Core should be used first]. Moreover, the metadata does not have to be
+stored in DC, but could be converted to it upon request by the
+harvester. But we consider using DC anyway.
+
+eSciDoc and formerly eDoc are capable of providing OAI-metadata, how
+to enable OAI-PMH for eSciDoc is described on the [https://www.escidoc.org/JSPWiki/en/OaiPmh escidoc-Wiki].
+
+The Data Provider is a server that can process the 6 OAI-PMH requests.
+PMH means Protocal for Metadata Harvesting.
+
+== Harvesters ==
+Harvesters are Service Providers. They can search an OAI-metadata
+repository for you. Harvesting is not crawling: the metadata are
+retained in their original form, which makes sense. To make oneself
+known to harvesters, one should register the repository.
+
+== Search capabilities ==
+According to eSciDoc, you have advanced search capabilities via (in
+the case of eSciDoc) CQL (Common Query Language): Boolean, String,
+Phrase, Fuzzy and Near.
+
+=== Register your repository ===
+The existence of the repository can be made known by registering the
+repository on the [http://www.openarchives.org/data/registerasprovider.html OAI site]. It is required that the repository
+conforms to some rules:
+
+The requests that the repository gives out are to be in XML and they
+have to comply to an XML schema. And it is helpful if the metadata
+output is in oai_dc, that is, dublin core.
+
+Every metadata record has to have a unique identifier. It is only
+mandatory that the identifier is unique in the repository itself.
+However, it is also possible to turn this into an OAI identifier in
+the OAI namespace.
