It is described in details at pmem.io, look at Documents, see
http://pmem.io/documents/NVDIMM_Namespace_Spec.pdf see Namespaces section.
Then I would recommend you read:
http://pmem.io/documents/NVDIMM_Driver_Writers_Guide.pdf
followed by http://pmem.io/documents/NVDIMM_DSM_Interface_Example.pdf
And then for dessert:
https://www.kernel.org/doc/Documentation/nvdimm/nvdimm.txt
which explains it in more technical terms.
