I’m working a bit backwards here, because I’m now moving on to the use cases that got me thinking about this in the first place. It’s easier to think about them now that I know that I can implement them using standard syntax and multiple open source implementations of that standard. I wanted to outline my ideas about how to…

I’d like to thank everyone who added comments to my last post, Some questions about RDF named graphs.
