Add support for links to resources

Add an e.g. `deepLink` property to the schema that allows generating links to a resource given `identifiers`. This is useful for the console.

Start with the resource schema and the console use case described in the issue, focusing on how identifiers are represented. Determine the expected shape and semantics of a deepLink property, then verify that the schema can express links generated from resource identifiers and that the console use case is covered.
