Linked Data Lookup Field
This module provides an autocomplete field widget that allows users to select suggestions and URLs from authoritative external data sources. It supports various data formats and can be extended to include custom endpoints, with built-in examples for services like Library of Congress Subject Headings. The field can then be displayed as a link to the source or using a custom formatter.
Provides an autocomplete field widget that pulls suggested matches and URLs from authoritative sources.
The module lets you configure your own endpoints, as long as they output JSON-formatted data, you should be able to create an autocomplete field that draws from it.
Out-of-the-box examples include support for Library of Congress Subject Headings, Global Research Identifier Database (GRID) entries, and Australian and New Zealand Standard Research Classification Fields of Research identifiers. New configurations that you add can be exported as configuration entities.
Plugins provide support for requests with a query as part of a URL, and also lets you create endpoints with custom SPARQL queries.
The field is then rendered as a link to the authoritative source, or a custom field formatter can be used.
This module is a generalization of the LC Subject Field module.
We encourage and look forward to contributions that add support for other sources.
