Web services

SPARQL endpoint

The Nomenclature SPARQL endpoint allows exploration of the dataset and output in a variety of formats. Sample queries are provided as examples to get you started using SPARQL.

API (coming soon)

Embedding Nomenclature concepts in your website

Some museums or collections management software vendors may wish to embed a view of the Nomenclature concepts within their own online tools, using stylesheets (CSS) to match the look and layout of their own web pages. To do this, web developers need to:

Several calls can be combined on the same HTML page.
For example:

The phrase "Please wait for content to load…" has been included to let users know that it may take a moment for the external Nomenclature data to load into the page. This phrase can be customized as needed.

Note: the render of the page will require your customized CSS to make it look like your own site.


Semantic model documentation

The Semantic model documentation is relevant for audiences interested in using the SPARQL endpoint of Nomenclature, or downloading the full dataset in RDF/XML, Turtle or JSON-LD format.

Descriptive information about Nomenclature

Machine-readable information describing the Nomenclature dataset and ontology is provided to allow semantic agents to more easily find, register, summarize, analyze, and consume Nomenclature linked data. Information on Nomenclature’s content, structure, licensing, access, properties and classes, and basic statistics are included. The main ontology used in this descriptive file is the Vocabulary of Interlinked Datasets (VoID). The Data Catalog Vocabulary (DCAT), the Asset Description Metadata Schema (ADMS) and others are also used.

This file is updated nightly to refresh dynamic information such as number of concepts, number of triples, and date of last update. It is provided to facilitate automatic discovery.

The following files contain the same descriptive information about Nomenclature, but in different RDF serializations. The Turtle (.ttl) version includes comments and arrangement that make it more human-readable.

The following link will re-direct to either a Turtle, JSONLD, or RDF/XML file, depending on your HTTP header request. By default, the semantic HTML view will be returned.


Downloading a current version

Nomenclature is continuously updated, and will no longer have named versions, as the printed volume did. The filename contains a date to help you identify when you last downloaded it. Data model information is provided in the Web Services and Documentation section below.

Downloading a conversion file

This file is not needed for new implementations. It may be useful as an interim step for those who previously implemented Nomenclature (e.g. Nomenclature 3.0 or 4.0) in their systems. Since the current version of Nomenclature excludes inverted order for terms made up of single words, this file containing all inverted-order terms (both single- and multiple-word terms) matched to the new Nomenclature IDs may help with conversion from systems that rely on the inverted order. After using this file to add the new Nomenclature IDs to your system, you will be able to use the IDs to update to the current version of Nomenclature.

If you are implementing Nomenclature for the first time, use one of the current versions provided above, instead of this conversion file.
