## What it is
A JavaScript implementation of the JSON-LD 1.0 and 1.1 W3C specifications, providing expansion, compaction, framing, and RDF dataset conversion APIs. It lets developers add linked-data semantics to JSON in Node.js and browser environments.

## Use cases
- process and expand JSON-LD documents in JavaScript
- convert JSON-LD to RDF datasets and back
- compact JSON-LD with a context for compact output
- frame JSON-LD documents to a desired shape
- add linked-data semantics to existing JSON APIs
- store linked data in JSON document databases like MongoDB

## When to choose
- you need a spec-conformant JSON-LD processor in JavaScript or TypeScript
- you are building verifiable credentials or semantic web tooling in Node.js or the browser
- you need interoperability between JSON APIs and RDF/linked data

## When to avoid
- you only need plain JSON parsing or serialization without linked-data semantics
- you need streaming JSON-LD processing (use jsonld-streaming-parser/serializer instead)
- your primary environment is not JavaScript-based

## Facets
- artifact type: library
- maturity: active
- function: serialization, parser, json
- domain: web-development, apis
- platform: browser, cross-platform
- tags: json-ld, linked-data, rdf, semantic-web, w3c-standards, data-engineering, nodejs, javascript
