2 IST Uwe Müller, , Les rencontres d'Aliénor: OAForum - A European view on the Open Archives Initiative Agenda 1.Open Archives 2.The Open Archives Initiative 3.OAForum: The European View 4.Open Access to Museum Information

3 IST Uwe Müller, , Les rencontres d'Aliénor: OAForum - A European view on the Open Archives Initiative Open Archives Different types of archives scholarly publication server (pre-prints, e-prints) libraries (OPAC, e-journals) museum databases (object metadata) archives (historical documents) and cultural heritage education Origin self archiving unclosing existing databases establishing new databases open archives approach gains popularity cross archive access low cost dissemination of previously hidden resources building of new service provision

4 IST Uwe Müller, , Les rencontres d'Aliénor: OAForum - A European view on the Open Archives Initiative Open Archives: Problems Problem: lacking interoperability different metadata standards Different terminology different languages different access strategies different interfaces / transfer protocols different copyright regulations Difficulty to establish new services cross archive access approach: Z39.50 protocol search distributed databases homogenously mainly used for bibliographic data

5 IST Uwe Müller, , Les rencontres d'Aliénor: OAForum - A European view on the Open Archives Initiative Open Archives: Problems (2) Metadata different formats (DC, MAB, MARC, …) different interpretation possibilities (Creator: Author vs. Artist vs. Photographer) Transfer protocols libraries: Z39.50 NCSTRL: DIENST protocol harvest systems: HTTP based Search methods database based vs. file system based DB: real time, ODBC, SQL, PHP, Perl etc. FS: no real time, index file, SOIF

6 IST Uwe Müller, , Les rencontres d'Aliénor: OAForum - A European view on the Open Archives Initiative Agenda 1.Open Archives 2.The Open Archives Initiative 3.OAForum: The European View 4.Open Access to Museum Information

7 IST Uwe Müller, , Les rencontres d'Aliénor: OAForum - A European view on the Open Archives Initiative The Open Archives Initiative (OAI) Main ideas world-wide consolidation of scholarly archives free access on the archives (at least: metadata) consistent interfaces for archives and service provider effortless implementation based on existing standards (e.g. HTTP, XML, DC) Basic functioning HarvesterRepository Requests (based on HTTP) Metadata (encoded in XML) Metadata (Documents) Metadata Service ProviderData Provider Service

8 IST Uwe Müller, , Les rencontres d'Aliénor: OAForum - A European view on the Open Archives Initiative OAI: Organisational Structure Steering Committee general policy of OAI 12 members (USA, United Kingdom, Germany) Executive Committee operational decision Carl Lagoze (Cornell University) Herbert van de Sompel (Los Alamos National Laboratory) Technical Committee formulation of the OAI protocol specification contact with OAI community Executive Committee + 14 members (USA, United Kingdom, Denmark, Switzerland)

9 IST Uwe Müller, , Les rencontres d'Aliénor: OAForum - A European view on the Open Archives Initiative OAI: General Assumptions 2 groups of participants Data Providers (Open Archives, Repositories) free access of metadata not necessarily: free access to full texts / resources easy to implement, low barriers useable for small institutions Service Providers use OAI interfaces of the Data Providers harvest and store metadata may select certain subsets from Data Providers (set hierarchy, date stamp) may enrich metadata offer (value-added) service on the basis of the metadata

10 IST Uwe Müller, , Les rencontres d'Aliénor: OAForum - A European view on the Open Archives Initiative OAI: Technical Model Service Provider e-print Data Provider e-prints e-print Data Provider Images e-print Data Provider OPAC e-print Data Provider Museum e-print Data Provider Archive Requests: Identify ListMetadataformats ListSets ListIdentifiers ListRecords GetRecord Responses: General information Metadata formats Set structure Record identifier Metadata Data Provider Harvester Repository

11 IST Uwe Müller, , Les rencontres d'Aliénor: OAForum - A European view on the Open Archives Initiative OAI: Protocol Basics and Details Basics of OAI-PMH protocol based on HTTP request arguments as GET or POST parameters six request types e.g. responses are encoded in XML syntax supports any metadata format (at least: Dublin Core) Details of OAI-PMH logical set hierarchy (definition: data providers) date stamps (last change of metadata set) error messages flow control

12 IST Uwe Müller, , Les rencontres d'Aliénor: OAForum - A European view on the Open Archives Initiative OAI: Protocol Basics and Details (2) Metadata sets (Records) 1.header unique identifier (key for further archive requests), e.g. oai:HUBerlin.de: datestamp, e.g logical sets in which the record is contained 2.metadata metadata prefix metadata set (at least: Dublin Core)
