subscribed), but here it is...]
Herb, I'll reiterate my point from od-discuss that the PDDL and CC0 are,
in practice, no different in the respect you're talking about. Both
include explicit disclaimers of liability.
However, from what I took away from your post on od-discuss, what you're
really arguing for is that the licensor should provide a warranty that
she or he has properly cleared all copyright in the works (and perhaps
even provide an indemnity to the license user). Neither the CC0, nor
the PDDL, nor any other open license that I'm aware of -- other than the
obsolete CC 1.0 licenses -- do this.
For the benefit of everyone on this license, I'll cross-post the reason why:
I also doubt we'll see new licenses take this approach. I agree that
the publishers of data are almost always in the best position to analyze
whether they actually hold the rights; however, I still don't think it's
feasible to shift the legal responsibility to them. This is essentially
asking the publisher to offer a warranty or copyright indemnity of
almost limitless scope (given that an open license offers the data to
users for ANY use whatsoever, including in business contexts which could
involve numerous copies with very high damages for an accounting of
profits or statutory infringements where a work turns out to be
infringing).
It's simply too much unknown risk and would deter publication (or, more
likely, would deter use of such a license). Keep in mind that
copyrighted content could easily creep into a dataset without the
publisher being aware of it. For example, photographs could
inadvertently include substantial amounts of other works that turn out
to infringe copyright.
In general, I probably tend towards a pro-licensee side of the fence ,
if anything, but I just don't see this one happening. IMO, the most
reasonable balance is that licensees and licensors each have to fight
their own legal battles: no warranty or indemnity going either way.
Now, having said this, I think data providers could do a better job of
describing -- and using metadata to describe -- the source of data, the
accuracy of data, and any quality control and rights clearing measures
that they have already taken. This way, data users will be better
informed of the legal risks that they're taking on when they use data
for a particular purpose.

CONFIDENTIALITY CAUTION AND DISCLAIMER
This message is intended only for the use of the individual or entity to which it is addressed and contains information that is privileged and confidential.
These are licenses intended for reproduction downstream by third
parties. If the implication is that by simply reproducing an OGL dataset
(say in the OpenDataBC catalogue) that we're taking on significant
rights-related liabilities, well, yes, I'd say that's a big problem.
If the govt distributed a dataset to 5 people, and those 5 people on to
100,000... and so forth... how would liability be apportioned? Only the
original publisher err'd, but the rest are liable (and by my read,
-more- liable), because they redistributed a copyrighted work more times?
I expect the publisher of content to not license content they don't own
or are unsure if they own. I'm also not aware of any of the GPL/code
style licensing allowing for this third-party-rights exemption, but
maybe the CIPPIC folks could do a comparison to the GPL/MIT/BSD licenses?
On the other hand, PDDL disclaims all warranty (s. 5.1) and then
disclaims ALL liability (s. 5.2) -- not just liability for rights
clearance:
5.1 The Work is provided by the Rightsholder “as is” and without any warranty of any kind, either express or implied, whether of title, of accuracy or completeness, of the presence of absence of errors, of fitness for purpose, or otherwise. Some jurisdictions do not allow the exclusion of implied warranties, so this exclusion may not apply to You.
5.2 Subject to any liability that may not be excluded or
limited by law, the Rightsholder is not liable for, and
expressly excludes, all liability for loss or damage however and
whenever caused to anyone by any use under this Document,
whether by You or by anyone else, and whether caused by any
fault on the part of the Rightsholder or not. This exclusion of
liability includes, but is not limited to, any special,
incidental, consequential, punitive, or exemplary damages. This
exclusion applies even if the Rightsholder has been advised of
the possibility of such damages.
Thus, the difference is that CC0 doesn't disclaim the licensor's
liability outside of copyright, whereas PDDL does. Both disclaim
liability for copyright clearance.
I concur this is important to reflect in a machine-readable
schema -- perhaps an indication on whether the license includes a
"Disclaimer for tort / extra-contractual liability" and whether
the license includes a "Disclaimer for copyright clearance". In
this case, PDDL would have a check-mark on both, whereas CC) would
only have a check-mark on the latter.
