[external] enumerations (name, URL) would hopefully reduce the number of misspelled schema.org/Text properties (so that faceting by this attribute is reasonably feasible without extensive de-duplication) we could include Text in the range for courseDeliveryMode but expect URLs of Enumeration Things with names (because those are translatable) > 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. -1 on "everyone will realize they need to go back and re-work to upgrade from Text to URL later" * "IDK, the person who did it last semester must've done it wrong and it's too late to change now" Here's how those go (folksonomy -> structured vocabulary): - "Interactive Audio/Video" - "Audio/Video" - "AV" - "Audio-Video" - "Audio" - "Video" - https://ceds.ed.gov/element/001161#AudioVideo With just Text, there's not enough information. * RDF requires URLs (IRIs) as subjects (not Text) * <#AudioVideo> a Enumeration * <#AudioVideo> schema:name "Audio/Video"@en * <#AudioVideo> schema:name "ljud video"@sv * <#AudioVideo> schema:description "Course is taught via remote interactive receiver or via streaming media technologies." # CEDS * When you want to GROUP BY courseDeliveryMode, if they're not all consistent URLs, it's very noisy/lossy/insufficient (and then faceted interfaces don't work without deduplication) > > > CourseDigitalFormat > - I am not convinced we even need this as a property.

There's no need for a separate thread; or a separate mailing list; or a separate issue ticket. - [ ] Add the property (courseDigitalFormat) - [ ] Add the External Enumeration class (CourseDigitalFormat) # see above/below - [ ] Create a wiki page to host said Enumerations - [ ] REQ: @vendors: pick a camelCase URL for a SMWiki page > > > W3C support for Semantic MediaWiki > - What level of support?
