Sure, that's identification. It's the ACL that I'm concerned with if the ACL is complicated. ] You can have Partitions (Named Graphs) with records for #Kingsley that ] cover his blogs, wikis etc. You can have another Partition covering HR ] records for #Kingsley where property values may include Salary, National ] Insurance Number etc.. ] ] ... ] ] Do you mean Named Graph? Basically, you have an IRI for each of the ] Graphs associated with the records/triples you mention above? Yes. The graphs are small and each contain triples directly relevant to what is treated as an "object" at the webapp level. There are two reasons for this. The first is relating to what happens when you dereference a URI. The webapp just pulls the graph named with that URI and gives it back in its entirety. This could be emulated by instead doing a symmetric-bounded-concise-description except for what happens when a write operation is performed. We have a requirement for keeping change history. So when you save a graph, a diff is done and saved. Because the graphs relate to an object you can walk the object's change history, undo changes, etc.. Because graph diffs are expensive it is also best to keep the graphs small. Maybe this could also be done by performing the diffs on the stored and new SBCD...
