Yes, it complains about q:spaces.live, but I think that's because that  
turtle parser is out of date. It passes raptor's syntax test.

Yeah, sure, the schema is a bit crude, it's the bare minimum needed to  
make the site go.

No, there wasn't time to document it unfortunately.

The properties of a property are just for compactness. We could have  
reified everything, but it would have bloated all the data. q:modules  
are an internal thing that tell us what piece of code to use to  
extract data from each type of resource.
