No comment ;)

3. makes the most sense in this context, as we don't have access to
the EasyChair XML output and 2 would duplicate effort when 3 is
already in place.

Aren't these both fairly generic properties that may best live
somewhere less conference-specific? Picking up on Damian's point, I'm
also not a huge fan of swc:url. In the past did we not just do sameAs
between the 'uri for the paper' and the uri for the corresponding pdf,
giving a bit of a handwave to any frbr-like issues? Having said that,
frbr:realization would seem a better way to proceed long-term, as
Damian suggests.

The curse lives on ;)

Have a nice weekend, and enjoy eating something else other than
DogFood. I'd recommend a good pizza.
