From https://github.com/RusticiSoftware/TinCanSchema/issues/7 :

From http://schema.org/Action :

An action performed by a direct agent and indirect participants upon a direct object. Optionally happens at a location with the help of an inanimate instrument. The execution of the action may produce a result. Specific action sub-type documentation specifies the exact expectation of each argument/role.

We have some example statements using JSON-LD @context here: https://github.com/adlnet/xapi-ontology.

But from what we've heard from the community...moving from JSON to JSON-LD would likely be a breaking change. So we have it in place, but most likely won't be applied until the next version of the spec.

BTW, we recently applied JSON-LD (linked data) approaches to the guidance around xAPI profiles, here: https://github.com/adlnet/xapi-profiles

good to hear, thanks! There are more and more resources with (schema.org,) JSONLD and/or RDFa; being able to do everything with just one parser would/will be outstanding.

AAIU, the schema.org/educationalAlignment work came from LRMI.

schema.org/Course , schema.org/CourseInstance , and schema.org/EducationEvent are all live now.

H5P looks really cool and is integratable with {WordPress, Moodle, Drupal}.

https://h5p.org/content-types-and-applications

H5P does support TinCan / xAPI: https://h5p.org/documentation/x-api

With a bit of schema.org JSONLD / RDFa it'd be really easy to find educational activities.
