Fwd: machine readable public domain declarations

Dear all,

This is from someone I know in Riga who works on a variety of things 
including open government data. I believe we have his use case covered 
but what's the best advice we can offer now?

Phil.

Hi Colleagues,

Is there a way to describe public domain declarations (such as CC0) in a
machine readable form?

CC-Rel is used for defining machine-readable information about CC-*
licences but I could not find how to mark up a public domain declaration
using it.

Use case: we need to find a way to declare [in a machine readable way] that
a dataset, according to the law, is public domain. However, government
organizations are reluctant to use licenses (CC0) that are developed
elsewhere. So the question is how to define a localized public domain
declaration (that includes machine-readable information).

Thanks,
Uldis
