Just to add the following:

During the UC review carried out by the BP group, one of the points
that were made was that requirements should be grouped based on
whether they were specific to spatial data or concerning any kind of
data on the Web.

The BP reqs page on the wiki reflects this "classification" [1].

PIDs can well be considered as a common requirement for any data on
the Web - and, actually, the DWBP WG covers this in BP-8:

http://www.w3.org/TR/2015/WD-dwbp-20150224/#ProvideUniqueIdentifiers

BTW, the recent publication of the DWBP WG working draft raises the
question on how we plan to integrate their BPs (although still
unstable) in our work - especially on the scope of our BPs.

Cheers,

Andrea
