Glad you mentioned that.
We registered this several years ago. http://id.loc.gov/datatypes/edtf/EDTF
(or in rdf: http://id.loc.gov/datatypes/edtf/EDTF.rdf )
We haven't publicized it, but you're free to use it, e.g. "2001-34"^^edtf:EDTF"
where edtf: is the prefix for http://id.loc.gov/datatypes/edtf
There is a slight complication. http://id.loc.gov/datatypes/edtf itself is a datatype scheme, meaning it is a group of datatypes, four of them, one for edtf in general and one for each level. I am going to try to get this changed. I don't think there needs to be more than one datatype (edtf general) and therefore no scheme.
If we make this change, you would instead say: 2001-34"^^someprefix:EDTF
Where the prefix is for http://id.loc.gov/datatypes/ (I don't know at this time what the recommended prefix will be, because we don't define any other active datatypes.)
I'll keep you posted on this.
