This article about Tim Berners-Lee speaking out in favour of an open
access to geodata policy for the UK's National Mapping Agency is
wonderful to me because he directly describes so many of the reasons
why i've been doing what i'm doing; his vision of the geospatial
web and the semantic web enriching each other, tending towards the
same thing; a data infrastructure that is patterned, not supplied.
But the Ordnance Survey's response (to offer, if not definitely, an
"open" API that will be constrained by a noncommercial use clause)
is hugely problematic to me, and connects to why i've been obsessing
about licensing issues so much recently. (Apart from Rufus' constant
conversational nudging on the topic, and the big OSM licensing debate
that led to Steve creating http://wiki.openstreetmap.org/index.php/Legal_FAQ )
- Non-commercial use does not equate with open, because it imposes
constraints on re-use and redistribution.
- I can't include a dataset licensed to me for noncommercial use in
an open source software package distribution, because i can't
provide a guarantee that it won't be put to commercial use.
- Noncommercial doesn't help fix the problem that the OS, USGS and their
fellow national mapping agencies are facing, in terms of increasing
pressure to "recover the costs" via monopoly pricing strategy in
order to be able to maintain high-quality updates to data.
In my brief response to Richard's ShareAlike Considered Harmful
piece, i went over this a bit:
( http://mappinghacks.com/2006/03/11/sharealike-considered-harmful-for-geodata/ )
In the open source worldview there is a concept of a ShareAlike
license. Data can be made fully and openly available for all uses
including commercial uses, with the constraint that if improvements
and enhancements are made to the data, those changes are made
available in the public domain, covered by the same license. The
Public Geodata License (http://cemml.carleton.ca:8080/OGUG/pgl/
provides a good model for this.
This isn't only model for making geographic data available
in a more open way, but it's a good one for state-collected
information and public sector information in general. A ShareAlike
license applied to distribution of Ordnance Survey data would help
fulfil the purpose for which it is suppose to exist, to collect and
redistribute the most current and accurate description of the UK that
is available.
- Noncommercial means that public geodata won't be able to generate
added economic value through reuse. The late Peter Weiss' study on
pricing public sector information is very strong on this point:
http://www.primet.org/documents/Weiss%20-%20Borders%20in%20Cyberspace.htm
Economic Potential of PSI in Europe and US
In EUROs EU US
Investment value 9.5 billion 19 billion
Economic value 68 billion 750 billion
- An Argument I very often hear from European NMA lobbyists is that,
with no obligation to return updates to the public domain,
commercial offerings can take a data set (such as TIGER), augment
it, fix and improve it, with no obligation to return the value added
to the data to the public, to be part of common wealth.
(Ed Parsons is offering this argument, in the interview that Steve did
with him yesterday as an inaugural podcast, http://www.opengeodata.org/?p=44
and which Schuyler and i transcribed a section of this evening:
http://wiki.openstreetmap.org/index.php/Opengeodata.org#Transcript )
PGL/ShareAlike for publically funded geodata helps get past this problem,
if one thinks of what NMAs are trying to achieve as providing better
and cheaper geodata for the public and for government, rather than
pursuing a very narrow view model of monopoly pricing in order to
recoup maintenance expenses.
With a ShareAlike model license, commercial offerings can add value in
terms of useful services, interfaces, but updates that are to the data set
directly, go back to improve the common wealth of data. With a
Noncommercial license tied to an API, we get nothing that we can reuse
outside of a hackademic ghetto, wide open to conceptual exploitation.
okay, i didn't mean this to be an essay, i just got overexcited.
