Cf https://github.com/OSGeo/gdal/pull/8558: "GPX: add a CREATOR dataset
creation option"
It will be of course up to the application / application user to set it.
I've considered a global GDALSetDefaultCreatorApplication() (could be
similar to CPLHTTPSetDefaultUserAgent():
https://gdal.org/doxygen/cpl__http_8h.html#ae83c06d51089bb340ed0b98a6ed8d01d)
so that an application could set a default for all formats that write a
creator application, but this leads to introducing potential options to
express "totally replace the GDAL version" vs "add my name in addition
to the GDAL version", or "put application/version number only when
required by the format" vs "put application/version wherever the format
could allow it, but only if there's a standardized location to do so" vs
"put application/version wherever the format could allow, potentially it
in a custom metadata item if there's no standardized location". e.g in
netCDF, we have a custom attribute GDAL = "GDAL x.y.z, released
YYYY/MM/DD" (it would not be appropriate to put the identification of
the larger application in it, given the name of the attribute and the
fact that GDAL itself parses it on reading to determine the bottom-up vs
top-up orientaiton). So I've not pursued this given all those dilemmas :-)

I am a member of the GPX standards list, and we are discussing a new
version and also dealing with broken data.
I wrote a gpx (from geojson), with just ogr2ogr, and the creator looks
like this:
creator="GDAL 3.5.3"
that's arguably totally fine with ogr2ogr.
But it seems that if some random big program links with gdal and uses it
to produce a file, the creator is just GDAL, and not "qgis 3.28.5 via
GDAL 3.5.3" or something like that. I groveled over all my gpx files
and found none that indicated anything like this.
It would be helpful to the GPX community if files were attributed to the
larger software as well, so that they can be chased down or at least
understood to be separately broken.
I don't see anything at
https://gdal.org/drivers/vector/gpx.html#vector-gpx
that could be used to do this.
Does this make sense to people here?
Is there any facility that would do this, that people just aren't using?
Any other thoughts?
Greg
