[cc-licenses] Serial Numbers and clarification of terms, (data & science commons)

Taking a broader view than just CC, or "The Commons", there are increasing Gov't initiatives around the world to openly release reports & data to facilitate reuse & add value.

There are, or at least I believe there are, a number of shortcomings with respect to CC licences in this domain, one of which is related to this thread. With a global trend towards federated metadata catalogues, as discovery tools with delivery mechanisms incorporated, UUID's are a prerequisite. Most cataloguing software applications generate them for records entered locally, and use things like timestamps & MAC addresses to ensure a statistically robust uniqueness across multiple application instances. 

If CC was able to provide not just licences, but a robust globally available UUID/GUID service, that not only generated the ID upon request, but maybe also provided a registry of allocated ID's (perhaps via the OGC CSW protocol), I think this could be well used.  

Such a service could also provide a parent/child service, so that a dataset could be registered, and any revised versions, reports or analyses using these data could be linked to the original.

This would be a significant change in scope for CC, and would perhaps be more in line with a Science or Data Commons than a Creative Commons, but with the discussions around a direction & needs for CC4, and an increasing use of CC licences applied to datasets, I think it is worth tossing into the discussion here.

https://creativecommons.net/r/2/ is the registry entry for my blog, for example.

We don't hand out a "serial #" but that'd be trivial.

Overall, "digital copyright registries" have an at best underwhelming
history. Over the past few years we've sometimes had a "register" or
"catalog" your work option on the license chooser results page, but
have removed it as it never resulted in a mass of registrations, but
did result in a mass of confused inquiries.

SafeCreative seems to be the most successful pure play in the space.
RegisteredCommons was early and still exists, and was fairly well
known at launch among the CC community, but very few works are
registered after many years. A number of services claiming to be
digital copyright registries look rather scammy. Much more interesting
and successful are things that don't primarily intend to be
registries, but are useful (or even problematic) as such as a side
effect of some other objective. The materials at
are dated, but I don't think there has been nearly as much progress as
people with high expectations from registries would've hoped, and my
slides/presentation are still a decent conceptual overview of the
space, if I may say so.


Regarding 4.0, I don't think any considerations for registration (or
provenance more broadly, beyond the license notice and attribution
conditions) should be built into the licenses, but of course specific
proposals are welcome.

One can imagine CC licenses more perfectly mirroring the usual set of
copyright reform proposals. More limited duration and expanded and
more certain exceptions and limitations have both already been
discussed on this list recently. Formalities are certainly another one
of those.
