Re: Attempt for a List specification in RDFa (ISSUE-106)

Jeni, see my recent post; I've abandoned the idea if lists within lists. I only attempted it to be on a par with Turtle, but it resulted in an unreasonable implementation.

This could be supported by having both @collection and @member on the same element, which would change the algorithm to continue processing the child elements to create a list which becomes a member of the parent list. For example:

The only chance of getting a change into microdata to supported nested lists is if there's a good use case for them. I'm happy to make the argument for them but I'll need some ammunition.
