OpenArchives.gr is the largest portal providing a single point of access to Greek scientific digital content of high quality.
It harvests the metadata of collections in Greece that are OAI-PMH compatible. Content providers are libraries, archives, academic and research institutions from Greece and Cyprus.
ΕΚΤ has recently migrated OpenArchives.gr into a new aggregation infrastructure offering new and improved search and browsing facilities and a more user-friendly interface.
Also, OpenArchives.gr focuses mainly on scientific and academic content. Cultural collections are available through .gr, the Greek Aggregator for Cultural Heritage Content.
OpenArchives.gr now has two new ways of publishing data. The Web API allows third-party applications to search for and display data aggregated here. Linked Data is a publishing approach which allows data integration and use.
EKT enriches and homogenizes the aggregated content against a hierarchical bilingual Vocabulary of Types that has been created.
Therefore, the content of OpenArchives.gr is been classified to a compact and balanced set of types which gives it semantic cohesion and improves its searchability, presentation and multilingualism.
