The image bank of Heritage Leiden and Surroundings contains a wide range of images: from original etchings by Rembrandt to born digital material of today. Partners, application developers and other interested parties can query the data in the image bank via an opensearch API (Application Programming Interface). For example, to use metadata and images for apps and web applications. The set currently consists of just under 80,000 records, but is continuously expanded and updated. These changes and additions are immediately available via the API. You can find the description document of the API at http://www.archiefleiden.nl/api/opensearch/description-document Below is an overview of the fields to be queried and the associated Dublin Core mapping: opensearch.mapping.Beschrift=dc_description opensearch .mapping.Copyright=dc_rights opensearch.mapping.CityName=dc_coverage opensearch.mapping.Technique=dc_type opensearch.mapping.Create_Date=dc_created opensearch.mapping.Maker=dc_creator opensearch.mapping.Format=dc_format opensearch.mapping.Keyword=dc_subject opensearch. mapping.Date_period block=dc_date opensearch.mapping.collectionname=dc_isPartOf opensearch.mapping.Sort_document=dc_type Example query specific field: ?q=City name:leiden Questions about this dataset?
