The collection of Fotopersbureau De Boer is particularly notable for its abundance of subjects and size. It contains valuable material for research on current topics such as environment, energy, and social inequality, and provides a glimpse into the everyday lives of people.
The 'FAIR Photos' project has enriched the metadata of the collection by linking them to thesauri of locations, persons, and keywords in order to further open up the collection for use in research and the cultural heritage sector. This newly added information is reintegrated into the archive's collection management system to ensure long-term storage sustainability. This data deposition contains the enriched metadata in both CSV and RDF formats.

Data
The data are available in CSV and RDF Turtle format. Due to their abundance, the HisVis AI tags are only available in the RDF. Please note that at the moment of deposit, the URIs prefixed with https://data.noord-hollandsarchief.nl/ are not resolving and it is unclear if this will be made possible in the future. The UUIDs are however stable and should be able to be used to retrieve the resources in the future.
Almost all resources are modelled in the schema.org vocabulary (https://schema.org), with exception of person observations and reconstructions (cf. roar vocabulary, https://w3id.org/roar), and person names (cf. pnv vocabulary, https://w3id.org/pnv). To indicate the certainty of an AI tag, the rico:certainty property from the rico ontology (https://www.ica.org/standards/RiC/ontology) is used.
Where the schema.org vocabulary is not specific enough, other vocabularies are used to attribute a concept from the AAT (https://www.getty.edu/research/tools/vocabularies/aat/) or GTAA (https://www.beeldengeluid.nl/kennis/kennisthemas/metadata/gemeenschappelijke-thesaurus-audiovisuele-archieven) is attributed using the schema.org/additionalType property.
Only person data (observation and reconstruction) from 'public persons' are included. It may lead to URIs in the report data (via a schema:about property) that do not carry any other information. These can be filled in later (once the person is set to 'public', e.g. through disambiguation).
See the example below for an example of the RDF description of a single photograph and related resources.
CSV
The CSV files are generated from the RDF with the SPARQL queries in the queries folder.
photographs.csv - Each line is an individual photograph with its attributes and relations to other entities (e.g. reports, persons, locations) through one or more uuids. Information is given on:
