This page provides information on the current state of the data store.
For each resource class you can find a count of resources belonging to that class and a list of all indexed fields.
Indexed fields are those properties of a resource class that should be extra-fast to query for.
Resource classes and indexed fields are linked to their schema representations, counts to the triples view of the respective instances.
This way, you can get a comprehensive overview of all resources in the data store and the semantics of the stored information.
