# SSI Contexts

[JSON-LD context][] files related to [Verifiable Credentials][], [Decentralized Identifiers][], and [Linked Data Proofs][]. These contexts are used in [`ssi`](../README.md) but are packaged separately because their licenses differ from `ssi`'s license.

[JSON-LD context]: https://www.w3.org/TR/json-ld11/#the-context
[Verifiable Credentials]: https://www.w3.org/TR/vc-data-model/
[Decentralized Identifiers]: https://www.w3.org/TR/did-core/
[Linked Data Proofs]: https://w3c-ccg.github.io/ld-proofs/

## Updating

Sometimes context files change over time. This crate aims to keep up to date with upstream changes in the context files it contains. To manually re-fetch the context files, run the script [update.sh](./update.sh) in the source directory.
