Navigation and service



The TELplus project represented a further stage in the creation of the European Digital Library, significantly expanding its range of services as a result of the following improvements

  • Text recognition (OCR) of more than 20 million pages, previously only available as image files
  • Data which hitherto could only be accessed via a Z39.50 interface was made OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting) compatible
  • In addition, the national libraries of Bulgaria and Romania were integrated into the European Library as full members

The German National Library contributed mainly to the WP3 "Improving Access" work package. This was aimed at raising access numbers and improving user-friendliness by means of automatic vocabulary links and improved full-text indexing.

The final version of the prototype consisted of 700,000 full-text OCR-captured pages which can be searched using the Subject Headings Authority File (SWD), the Library of Congress Subject Headings (LCSH) and Rameau. In addition, all subject headings were converted into the Simple Knowledge Organization System (SKOS). The results of this prototype will be the basis for overhauling the European Library's portal interface during next year.

A further task was research in the field of automatic vocabulary links. Here, the subject headings linked in the MACS (Multilingual Access to Subject Headings) project were converted into SKOS. These results were also used as the basis for a prototype.
