To bring up again my question of a few days ago (and thanks for the
thoughtful responses), would not geocoded photos of signs be a great,
and perhaps the best, form of evidence?
The cautions on the website and list, against using copyright sources of
information to add to OSM, are very sensible, but is there a lack of
built-in defense, in OSM, against allegations of copyright infringement?
I am thinking especially of feature names. Clearly the GPX files
provide great evidence of someone having physically visited a location
or traversed a route. But what provides evidence of someone physically
collecting the feature name?
I have been reading the "OGL, OSM, NASA" thread, and children, with
interest. I can't help wonder, if OSM had built in to it great evidence
that all OSM data is clean, that people might feel more relaxed about
fusion products that mix OSM data and 3rd party data? What would we
have to fear, if every named way had attached to it a reasonable body of
evidence, such as georeferenced photos of signage, that OSM people had
been there and gathered the data? Perhaps OSM could make it hard to
name a way, unless such photos were also contributed?
Or perhaps I am missing some aspect of the copyright concerns. In any
case, thats enough of a rant for a newbie!
