The Europeana Business Plan 2014 was published on 12 March 2014.

Three of the Key Performance Indicators in the important Product Development section (see p.30) are being implemented by Ontotext within the frame of the Europeana Creative project:
•An OAI-PMH service to allow others to use EDM data in bulk
•Semantic repository (triple store), synchronized with the EDM data
•A SPARQL semantic querying endpoint

OAI and SPARQL access will be key new interface services in the upcoming Europeana Labs, complementing the existing Europeana API.

Additional notes about these key services:
•The Open Archives Initiative Protocol for Metadata Harvesting (OAI PMH) is the fundamental protocol for aggregating data from repositories. It is used by Europeana to ingest data from aggregators and providers. However, Europeana itself does not provide an OAI server until now, which is an important omission. The Europeana OAI server will be useful to keep the semantic repository up to date with new Europeana data; and to other large-scale consumers and aggregators
•Ontotext developed and hosts the Europeana semantic repository on OWLIM at http://europeana.ontotext.com. It allows display and downloading of RDF triples and custom views for each Cultural Heritage Object: portal view and graph view. We are currently working on the task of synchronizing through the OAI protocol.
•The repository provides complete SPARQL 1.1 support and a Full Text Search interface. While more Europeana objects are being semantically enriched, this querying interface will be useful to pose graph (relation-oriented) queries that cannot be answered through the existing Europeana API.
