Split out RDFa code from jsonld.js.

If this package includes an HTML parser (or at least a reasonable XML parser), perhaps it's the package for testing the HTML bits of JSON-LD?

Otherwise, I was considering some form of dependency injection so that jsonld.js can be compatible with HTML script extraction if a suitable HTML/XML library is present or otherwise injected.

[davidlehn]

I hadn't been thinking of how to do the HTML script code. This patch was partially to remove the xmldom dependency from jsonld.js itself. Maybe that will need to stay around somehow at least for testing. Should consider how that HTML script support works before this is split out in case there's a better overall design.

Yeah, I’ll work on that next. It’s entirely limited to the document loader

LGTM, thanks! I suggest using a more generic BSD-3 style license instead of copying the one from jsonld.js.

@gkellogg,

We should put the HTML stuff in a separate package so if it isn't needed, it doesn't have to be pulled in. Something like jsonld-html ... @davidlehn -- if you agree with that direction and naming, could you make that package and work with @gkellogg?

Perhaps we could install that package as a dev dependency for jsonld.js so we can test in one place if it helps.

I figured that's where we could go. We could either condition the built-in documentLoader on if xmldom (or similar) is loaded, or do a special-purpose documentLoader within that package.
