As well as being available through a browsable UI, HASSET is available as RDF data via a number of endpoints. HASSET is modelled primarily with SKOS but a small number of additional properties are used from other vocabularies e.g. Dublin Core (e.g. license) and XKOS.
Namespace and URIs
The base URI for all HASSET concepts is https://hasset.ukdataservice.ac.uk/ Note that the URL for the Skosmos platform on the Apache web server at the UK Data Service is https://vocabularies.ukdataservice.ac.uk . We have a number of internal redirections configured to handle HASSET URI requests, so that they land at the correct location. All identifiers for concepts are GUIDs (in the canonical format 8-4-4-4-12 for a total of 36 characters - 32 hexadecimal characters and 4 hyphens) and are unique and persistent.
The URI for any concept can be found on the detail page for the concept:
The URI for the HASSET concept scheme is https://hasset.ukdataservice.ac.uk All HASSET concepts are retrievable online as RDF data with a machine-actionable query; however, because of the size of the concept scheme (approximately 80,000 triples), we do not make the whole thesaurus available as a direct RDF query. If you need a copy of the complete HASSET as linked data, it can be downloaded from https://vocabularies.ukdataservice.ac.uk/downloads/HASSET_20210819.zip which contains RDF/XML, JSON-LD and Turtle representations of the thesaurus.
Methods to retrieve Concepts as RDF data
(1) Interactively in the Skosmos UI
RDF data for each concept can be retrieved by clicking on the relevant link in the Skosmos UI. RDF/XML, Turtle or JSON-LD formats are available. For example, entering the URI for the concept GAMBLING (https://hasset.ukdataservice.ac.uk/ee6df6e1-bd41-4d92-aa5f-6b0b8a7c0d8e ) into a browser will redirect to the relevant HTML page. RDF data for the concept can be retrieved by clicking on the relevant links in the detail pane - see below:
