Vicki, thanks for the heads up, I would have missed this otherwise.

I have added some comments to the Google Doc, the most significant are:

1. Courses can comprise Courses. This is especially important at Universities that recruit into and award certificates for programmes (Courses) that are built from modules (Courses).

2. I don't think there is much to be gained from having a separate class on OnlineCourse rather than a property of a Course to flag whether it is online or not. I  think the properties you have for OnlineCourse also apply to regular courses. Most regular courses have an online component.

3. I think it would be better to model an instance of a Course as a collection of EducationalEvents and CreativeWorks.

4. Language is difficult. The different usage between UK and US English is one thing, but more importantly commonly used terms often relate to specific education systems or pedagogies. So phrases like "instructors deliver lessons to students" implies a particular pedagogy. Also this means that common terms become ambiguous and open to misinterpretation in international use, e.g. class, course, programme, module. This is important in schema.org where definitions tend to be minimalist.

Hope this helps.

As a general question, do you have some usecases in mind and target example websites? It's difficult to assess whether these properties are sufficient and realistic without those.

(I commented on GitHub, but I am not sure if everyone is over there, so I am duplicating the message here.)

I have read through all of the comments and background links and attempted to pull the various ideas into a cohesive whole. My thoughts are still rather preliminary, but can be found at https://docs.google.com/document/d/12YWjLzZC8FiTiOwSAETRIEozeqZdn6O8a4fgqK4t5Ss/edit?usp=sharing

It would be nice to be able to support in-person classes (academic or not) and MOOCs.

Please comment here or on GitHub.

- Vicki

I've created a GitHub issue ticket for this Proposal:


cc'ing a comment here, because DRY:

What is missing or could be added?
>From http://lists.w3.org/Archives/Public/public-vocabs/2014Feb/0127.html :

  *   derivedFrom/previousIncantation property could also be helpful.

  *   prerequisitve/buildsUpon/suggestedPrerequisite properties would be great.

Types for these properties would need to be <Course>.
... This would then form a graph of Courses and/or OnlineCourses.

It may be most helpful to transition discussion to a task-focused GitHub issue.

In creating said ticket [openbadges/openbadges-specifiation/9], I'm having trouble linking to the entirety of a mailing list thread (who know).

Is there / should there be an issue for OnlineCourse here: https://github.com/rvguha/schemaorg/issues ?

1. Is it worth adding a "prerequisiteCourse" property to list the prerequisites for the given course?
    - IMO, "prerequisiteCourse" or "requirements" for the Course could provide rich snippets for users to know if it is appropriate for him/her.

Where can I add topical links to wikipedia (dbpedia [1])? e.g. This course is about https://en.wikipedia.org/wiki/Linked_data and https://en.wikipedia.org/wiki/Semantic_Web

2. Can we change "isCertificateAvailable" from a boolean to something with a little more data? Maybe the type of certificate granted or the institution granting the certificate?
    - +1, and then it will need Certificate type and additional properties to think about.

http://openbadges.org/ are gaining momentum. [2]

Would "credential" be a more generic predicate?
