something to one or more entities that may exist across multiple origins, in a

The mistake is to look for a universal solution. In fact, we could start by 
one useful semantic bucket. Once this is taken up, we can add other buckets. 
As there is no compulsory legal obligation, the only way to get PETs accepted 
is to offer benefits. This is hard in the absence of a legal system in an 
environment where you can collect everything and use it for every possible 
purpose. But it is meaningful in a regulated environment where it actually 
opens doors as it conveys permissions.
