:-) But honestly, kudos for letting us know.

Sure. I just created a Wiki page summarizing the current state of affairs:


Hope this helps. If not, please let me know.

To be honest, I'm not completely sure either. I asked a couple of months ago if ItemList could be used for something like this and how ItemList is intended to be used. I was told (by Jason from Google) the following:

    "I appreciate re-using an existing Class, but I think ItemList was
     intended for a different use case than collections (I've given
     the same feedback to Sam).  It's a subclass of CreativeWork
     because it's for "editorialized" lists (top 10 list, playlists,
     etc.). I think we need something new like an actual Collection
     class in schema.org"


Once we are happy with the Collection design we could try to propose it for inclusion into Schema.org.

AFAICT, LDP hasn't finalized their design yet (especially paging is still very much in flux). Furthermore, their containers enforce specific interaction models which turns it into a completely different design. I didn't add anything to the wiki, but feel free to start a new thread here on the list if you want to discuss this further.

I very appreciate that you "stepped in". The goal of this group should be to be as inclusive as possible. We are a quite interesting group as we have members with very very different backgrounds. This might make collaboration a bit more challenging from time to time but it is really a Good Thing™ :-) It ensures that we design a solid solution.
