Oasis Metadata Registry

This repository contains an off-chain registry of signed statements about various entities that may exist on the Oasis Network. Each statement is self-certifying and should be independently verified before being used.

For tooling that can be used to verify and access the signed statements programatically see the metadata-registry-tools repository.

Contributing New Statements

New statements can be contributed by opening a pull request.

To create an entity metadata statement using metadata-registry-tools, use the following steps:

  1. Create an entity-metadata.json file describing the metadata statement, for example something like (most fields can be omitted):

      "v": 1,
      "serial": 1,
      "name": "My entity name",
      "url": "https://my.entity/url",
      "email": "",
      "keybase": "keybase_handle",
      "twitter": "twitter_handle"

    Note that keybase and twitter fields should contain handles (usernames) not URLs. See ADR 0001 for the description of all the field formats.

    In case you are updating an existing entry, you must bump the serial number.

  2. Fork this repository.

  3. Use the oasis-registry command to generate a new signed statement. The command must be run in the directory where you cloned this repository. This will require the use of an Oasis Core signer (all the same signers and configuration flags are supported). For example, using a file-based signer:

    oasis-registry entity update \
      --signer.dir /localhostdir/entity \

    This will create (or update) the registry entry.

  4. Commit your changes in the registry/ directory and create a pull request. Make sure to NOT commit the plain entity-metadata.json file in case you created it in the same directory. The same metadata can be extracted from the generated signed entity statement.

  5. Automated checks will make sure that the signed statement is valid and that the update has been performed correctly.

  6. If all checks pass your pull request will be approved and merged. Once this happens the updated entity metadata will be available for queries.
