Each implementation must provide the version metadata endpoint, which must use the dspace-version Well-Known Uniform Resource Identifier at the top of the path hierarchy:
/.well-known/dspace-version
The contents of the response is a JSON object defined in the Dataspace Protocol.
Note that if multiple Connectors are hosted under the same base URL, a path segment appended to the base well-known URL can be used, for example, https://example.com/.well-known/dspace-version/connector1.
All requests to HTTPS endpoints should use the Authorization header to include an authorization token. The semantics of such tokens are not part of these specifications. The Authorization HTTP header is optional if the Connector does not require authorization.
