[josm-dev] Audio mapping Plugin

Hi,

The idea behind the marker layer is that it can have any number of 
markers placed anywhere on the map and these may take user input (mostly 
clicking). The marker layer is (exclusively ATM) created from <wpt> tags 
in the GPX file.

No, although they do share functionality; GeoImageLayer could probably 
dropped and its functionality (displaying images when you click on the 
camera symbol) could be modelled in an ImageMarker.

When I created the MarkerLayer I didn't want to change everything that 
was already there but with hindsight it seems reasonable to merge the 
GeoImage and the Marker stuff.

Your application is quite different though as it requires a kind of 
"linear" feature (not only markers) and is likely to produce animations 
as well (with a cursor moving in sync with the sound playback or so). So 
that would surely be beyond what the marker layer was made for. Doesn't 
mean you can't extend it of course.

A plugin would have the advantage that everybody can try it out and drop 
it again if they don't like it, without changes to their JOSM 
installation. If I understand you correctly, people would have to apply 
your patch and then recompile JOSM which few would do.

Ideally (I think) you should aim at making the required architecture 
changes in the JOSM core without adding functionality (or bugs ;-) 
there, and then make a Plugin that people can use if they want audio 
mapping. But that's just my 2 cents.
