each solid.storage element should allow including parsedGraph with labels etc.

I give each storage 'rdfs:label' and often create multiple storages for each person or group. App before making registration of a type in index, needs to prompt user to chose which storage should keep the data. For that it needs to show 'rdfs:label' of a storage.

solid.storage instead of URIs could store objects with { uri, parsedGraph } which would allow query the parsed graph for labels.
