RE: Enumerations: courseMode <CourseMode>, courseDigitalFormat <CourseDigitalFormat>, accessibilityPhysicalFeature <AccessibilityPhysicalFeature>

Hi all

I recall that CourseMode is also problematic, and perhaps symptomatic of likely difficulties in reaching consensus over enumerations.  In UK HE parlance that usually means full time, part time, and so on, and this is currently wrapped up in whether this means, or ought to mean, ‘attendance’.  For example, a recent data language project suggests that ‘full time’ in the context of delivery usually means attendance but also might include expected personal study time – I’m not sure how this squares with online or distance delivery.

CourseMode in Phil’s email is more explicitly to do with delivery mode, where face-to-face is one of many, regardless of full time or part time discussions.

The usefulness of the enumerations depends on purpose, and I suspect that even in the schema.org area with a relatively straightforward purpose of use on the general web, there will be difficulties in gaining consensus at this level of detail.

For these reasons I’d suggest that enumerations may be a bridge too far.

Hello Wes, everyone.
Yes, enumerations are good when you can reach consensus on what they should be. The problem is agreeing on them across the scope of all people who might use schema.org. External enumerations [1] would help by reducing the scope of the required agreement. In general, I think the enumerations can be added later. I think we can propose a property and then, when we see how it is used, add in enumerations as required.

Taking the properties that you suggest would benefit from an enumeration in turn:

AccessibilityPhysicalFeature
- I think this is beyond our competence. Physical accessibility for events / locations needs to be considered in a much wider context than Courses and by people who understand the issues involved. I would rather leave it to a different working group. (This incidentally is what LRMI did for accessibility of creative works, and it worked out quite well.)


CourseMode
- Agreed. The option set for the CEDS Course Section Instructional Delivery Mode https://ceds.ed.gov/element/001161 seems like a good starting point. I know Jim Goodell is interested in whatever it takes to make the CEDS vocabularies more usable in the wider RDF world.


CourseDigitalFormat
- I am not convinced we even need this as a property. Can we start a separate thread to discuss it?


W3C support for Semantic MediaWiki
- What level of support? The community group wikis are Semantic MediaWiki (at least according the badge on the bottom right of the schema-course-extend and web-schemas wikipages). Do you mean support in how to use it? I tried using SMW for a different task last summer and found it a difficult combination of RDF thinking and some of the more esoteric features of MediaWiki.

I wonder whether, for faceted interface support, we should have courseMode Enumerations?

We could define said Enumerations just like these:
https://www.w3.org/wiki/WebSchemas/Accessibility



AccessibilityPhysicalFeature (for Place, Event, CreativeWork, )
https://www.w3.org/wiki/WebSchemas/Accessibility PhysicalFeature
- name
- description
- url
- image / logo / photo (Creative Commons {SVGs,} would be great here)
- https://github.com/schemaorg/schemaorg/pull/972#issuecomment-173698449


CourseMode
https://www.w3.org/wiki/WebSchemas/CourseMode

- name
- description
- url


CourseDigitalFormat
https://www.w3.org/wiki/WebSchemas/CourseDigitalFormat

- name
- version
- description
- url


Suggestions:
- These Enumeration URLs should/could be copy-paste-able
- Semantic MediaWiki supports RDFa
  - IDK how feasible it would be to get W3C support for Semantic MediaWiki (or really who to contact for such a request)
