Datasets include full text files on digitized documents, metadata from library databases and vocabularies. Application programming interfaces, APIs, provide access to the data. APIs are specifications for how software can make requests and communicate with each other.
License: You can use this data freely for your research and applications.

Data sets
FulltextOur fulltext data sets contain both the complete text (often digitised and OCRd) as well as metadata about documents. |
MetadataOur metadata repositories contain records that describe documents, but the actual documents are stored elsewhere. For electronic or scanned documents, we provide a link to the document content. |
VocabulariesControlled vocabularies such as thesauri, ontologies and authority files are referenced from metadata descriptions. We provide access to controlled vocabularies mainly through the Finto service. |
OAI-PMHOAI-PMH is a protocol for harvesting metadata descriptions of records in a repository. We provide OAI-PMH access to several document and metadata repositories. |
RESTREST is n API implementation style that provides web services using the HTTP protocol. Our REST services provide access to system-specific functionalities for which no standardized protocol exists. |
OpenSearchOpenSearch is a collection of simple formats for the sharing of search results. Our OpenSearch endpoints can be used to search for entities and retrieve the results as an XML document. |
OpenURLOpenURL is a format for encoding a description of a resource within a URL, intended to help Internet users to find a copy of the resource that they are allowed to access. Our OpenURL services provide access to individual pages of scanned documents. |
Linked DataLinked Data is is a method of publishing structured data so that it can be interlinked and accessed by both humans and machines. Our Linked Data services provide access to bibliographic data as well as controlled vocabularies. |
Z39.50 and SRUZ39.50 is a client-server communications protocol for searching and retrieving information from a database. SRU is a successor protocol that is based on HTTP but provides the same facilities for searching. Our library systems support access via Z39.50 and SRU protocols for retrieving individual MARC records or relatively small batches of records. |
Digi download toolDigi download tool enables downloading material from Digi via its search URL to own machine. Inspection tool can be used to view, comment and delete downloaded material. |
