Disambiguating Things

I now have the need to disambiguate between Things at a deeper level than
just property comparisons.

I'd like to see the use or way of telling my apps that a checksum is the
disambiguatingDescription or identifier property on my Things.

Currently, we have no Type of "Checksum" under Intangible.  That might be
thoughtful in the future.

But we do have PropertyValue available, but it loses the

This need arouse from the recent introduction of "checksum" property in
Wikidata as well...hence my Apps can take advantage of that now but not
without Schema.org uplifts, since my Apps depend on valid properties in
Schema.org... (insert skunkworks stuff here)

I guess this is an alternative way to perform what I am needing

{
  "@context": "http://schema.org/",
  "@type": "Thing",
  "name": "Some IoT Thing",
  "url": "http://www.example.com/Some+IoT+Thing",
  "identifier": {
    "@type": "PropertyValue",
    "alternateName":"checksum",
    "additionalType":"https://www.wikidata.org/wiki/Q218341",
    "value": "8044d756b7f00b695ab8dce07dce43e5",
    "unitCode":"https://www.wikidata.org/wiki/Q185235"
    }
}

Thoughts or ideas or any;thing that I am missing ?

If the above is actually a really good example, then we should probably add
it as an 3rd example on http://schema.org/identifier  ?
