Generate JSON-LD Context Based on Property Names

[no-reply]

There is already a capability to a default context to #dump :jsonld by having #jsonld_context return it. A default method (or maybe a mixin?) that generates a context (& framing doc?) from property definitions would be valuable.

Presuming that ActiveTriples implements RDF::Enumerable, you should be able to call #dump(:jsonld, standard_prefixes: true), which will create a context based on vocabularies built in to RDF.rb. You can also pass specific prefix mappings.

Thanks @gkellogg, I always appreciate when you chime in on this project.

We've had good experiences with standard_prefixes: true, with output like this: https://gist.github.com/no-reply/8872f9672a4b31f60fcc

What we're thinking about adding is capacity to do something more like this: https://gist.github.com/no-reply/f425057a660ae910a239 output simply by calling agg.dump :jsonld.

Most of the info needed to setup a default context like the one above is already hiding in AT's properties. So this is about building that out, and maybe adding some optional property configuration to do the rest.

You might look at JSON::LD::Context#from_vocabulary which generates a good context from an RDFS vocabulary, it might help get you closer to something like this.

FWIW, it would also be great to be able to load a JSON-LD context when fetching. So, if http://example.com/foo/bar resolves to a JSON-LD doc, then:

res = ActiveTriples::Resource.new "http://example.com/foo/bar"
res.fetch

would create the properties as used in the doc with the predicates from the context.

Or, maybe you need a class generator for this ...
