[License-discuss] Derivative Works of a standard

[Grahame Grieve]

I am trying to pick an appropriate open license for a new standard in
the healthcare
space. The prospective standard and it's working license are here:
http://hl7.org/fhir

The working license is adapted from OMG. but I'm struggling to understand
the concept of derivative works when I consider the issue of standards. What's
a derivative work? As far as I can tell, it's any implementation that complies
with the standard, and that was written based on reading it. And therefore,
since the standards are - almost always - copyright, therefore, any product
that implements any standard needs to include the copyright notice associated
with the standard, per the recent emails on this list.

Clearly not, however, in practice. Why not? what's the difference?

Is it only a derivative work if it quotes at length from the source? more than
fair use? where do the html tutorials stand, then, that "derive" from the html
specification in violation of the w3c license?

I'm finding the concept of derivative works very difficult to define
for a standard.
And given the plain english intent of the standard at the link referenced above
(see below), does the osr have any suitable approved license? I can't find one.
In particular, we cannot have a requirement to reproduce the license/copyright
statement in implementations of the standard...

thanks
