The University Library strives to make its collections as open as possible, including the data and metadata required to access these, and to make the products of education and research of the institutions of the University of Amsterdam (UvA) and of education and research institutions across the globe as accessible as possible.

The licences and user rights referred to here, relate only to the Library's collection metadata, and not to the collection objects described by that metadata. Different regulations apply to these.

This concerns the data and metadata that provide access to the collections. The standard/default licence governing the Library's collection metadata is subject to an Open Data Commons Public Domain Dedication and License (PDDL). In summary, this means:

It is permitted, without attribution, to:

  • copy, distribute and use the data;
  • reuse the data to create new works;
  • modify the data.

There is one exception, in that the metadata originating from OCLC WorldCat are subject to an Open Data Commons Attribution License (ODC-BY), according to the WorldCat Community Norms (PDF, 2 pages). This concerns in particular part of the records in the Central Library Catalogue and the Image Repository. In summary, this means:

It is permitted to:

  • copy, distribute and use the data;
  • reuse the data to create new works;
  • modify the data;

provided that provenance is attributed to ‘OCLC WorldCat’ and that any use conforms to the WorldCat Community Norms:

'This license allows the data to be used for study and research, among other things, with attribution in derivative works produced from the dataset. If you plan to use the bibliographic data for other purposes, whether or not you are an OCLC member, we ask that you review and comply with the community norms.'

In practice, the citation requirement is met by using WorldCat URIs in the data. In the open datasets of the UvA/AUAS Library, these WorldCat URIs are present, if applicable.
