API

The library exports the following properties:

• CONTEXT_URL
• CONTEXT
• constants: A Object that maps constants to well-known context URLs. The main constant CONTEXT_URL may be updated from time to time to the latest context location.
• contexts: A Map that maps URLs to full context data.
• appContextMap: For use with cborld library.

Developing

WARNING: The .jsonld in contexts/ is auto-generated by the npm run build script, each time you run the test suite.

DO NOT edit it directly (or your changes will be quickly overwritten). Instead, make all context changes to js/context.js.
