Interface Format

public interface Format

This is the Planets 'Preservation Object' 'Format' description entity. It is based on the DROID FileFormat entity, but simplified. Other format registries could be supported too.

Note that DROID also provides: 'has priority over' (good for doing PP) and 'signatures' (good for doing PC) but as this is meant to be a simple, interoperable type identifier system, this extra information (which is more oriented to specific use contexts) is not included here.

Types are identified by URIs. As we are currently based on PRONOM, these URIs will be PRONOM info:pronom/fmt/XX URIs. By using these URIs, we retain the ability to add further registries in the future without changing any of this code.
