I have some questions regarding of "JOSM plugin public transport update" project. The quotations below come from the Project Idea => http://wiki.openstreetmap.org/wiki/Google_Summer_of_Code/2014/Project_Ideas#Editors
1. Where can I find description of tagging scheme that the project should support? I can read: "The JOSM plugin public transport is out of sync with the public transport scheme from the wiki.". Can I assume that http://wiki.openstreetmap.org/w/index.php?title=Public_transport&oldid=945502 is the documentation of the new tagging scheme? Or maybe it is http://wiki.openstreetmap.org/w/index.php?title=Proposed_features/Public_Transport&oldid=930877 ? 2. "Although bus lines follow most of the time the most direct way, the mapper has still to collect all these segments by hand. This is a really tedious job. A routing engine could suggest a route after the user has clicked starting and ending point. A sufficiently fast textbook implementation of an A* algorithm is present, it needs to be configured to the types of roads suitable for buses." I think that a bit different tool based on this idea would solve far wider problem. Linear features like highway=*, waterways and railways often suffer from fragmentation (and probably also other linear features). It makes many sort of edits overly complicated. Problem is limited not only to adding bus lines. Any edit that involves editing longer part of segmented linear feature triggers this problem. For example I encountered it during adding lit and surface info and it discouraged me from this type of edits. It is easy to imagine that the same will happen with many other edits. Moreover only starting and ending point are not enough to generate fully correct bus route. It will work only for specific routing of bus lines that may be rare in some countries (for example in Poland). Additionally JOSM has significant lag while operating at city-sized datasets (around 150MB) and changing this would be hard and complicated enough as separate project. Maybe it should not be a part of the specific plugin but should be developed as JOSM improvement and contributed directly as part of JOSM development (developing it would be a part of the GSoC project). In order to tag segment of bus route, it would not be necessary to manually select separate ways. It would be possible to mark two nodes and use the new function to select multiple ways connecting them (and possibly also split ways in cases where it is necessary). This would make possible to add them in one group. Bus route would consist of one (as in original proposal) or more segments. Example of separate ways: http://www.openstreetmap.org/way/81942097 + http://www.openstreetmap.org/way/81942097 + http://www.openstreetmap.org/way/218427525 + and 18 subsequent ways Example of two nodes, selecting them and using new tool would be equivalent of marking 21 ways from previous example: at http://osm.org/go/0L0Ncg8PB--?m= and at http://osm.org/go/0L0N2eLaV--?m= This approach may make coding more complicated but it would solve far more general problem. 3. "plugin should no longer break well-tagged existing structures" Should plugin fully support outdated tagging schemes? Or is it enough that updated plugin will not break it? 4. Where can I find bug tracker for this tool? I found http://svn.openstreetmap.org/applications/editors/josm/plugins/public_transport/ and its git mirror but I have still to find the bug tracker. This would be especially useful as project involves "improve stability such that no more crashes happen" and "plugin should no longer break well-tagged existing structures". I thought that maybe tickets reside at JOSM bug tracker but search for keyword like "public", "transport" and "public_transport" gives no useful tickets.
