Hi David,
Right, Cargo is stricter than Semantic MediaWiki about entering data: you
can't come up with your own property names and their values. I think that’s
a plus: the data structure, set of allowed values, etc. should be
consistent across all pages, not subject to arbitrary changes on
When I last tried semantic mediawiki (years ago), it permitted (perhaps
even emphasized) generating structured data through writing that contained
typed links. The "type" was a predicate that explained the relationship
between two pages. I think it was also possible to store a tuple of data
