Got it. So:



I'll create another issue for this.
https://github.com/schemaorg/schemaorg/issues/254#issuecomment-223049660

I feel like this would take one day; and then people could add to / update
the Enumerations
But it may be blocked by EnumerationValueSet (in which it would still take
one day).

I suppose it's not possible to clarify the demand question solely given the
existence of so many DigitalCourseFormats.

TBH, I think the relation is:

  Course <- CourseInstance.syllabus <-__- (CreativeWork >
DigitalCourse).digitalCourseFormat [DigitalCourseFormat]

But we've yet to decide how to build an ordered tree/graph which does not
lose ordering between RDFa parsing, JSON-LD, and JS objects (which are not
guaranteed to remain in source-order; unless the implementation utilizes
ES6 maps) for pleasant traversal. (see the comments about RDFa, rdf:List,
rdf:first, and rdf:rest in schemaorg/schemaorg#195)

OpenSyllabusProject (@opensyllabus) probably has an ElasticSearch schema
which could be mapped to a JSON-LD @context with a little tool called
elasticsearchjsonld; and then there's likely quite a bit of overlap with
whatever we define here for schema.org/Course. IDK whether they have
modelled DigitalCourseFormat or similar yet.

This wont work: DigitalCourseFormat  --> fileFormat (Text) <--
SoftwareApplication

There is no way to link from Text in fileFormat to even a Wikipedia page
listing implementations for a given DigitalCourseFormat (again because RDF
requires IRIs (URIs, URLs) in the subject of a (subject, predicate, object)
tuple or a (graph, subject, predicate, object) quad).

(name, url, version, description) would be most useful (and probably
necessarily externally defined)

("name [version]", url, description) would probably also work.
