[OSM-dev] JOSM plugin public transport update (Google Summer of Code program)

I wonder about checkpoints for "good standing with their communities"
on 19 May, "mid-term evaluation" on 23 June and "final evaluation deadline".
Should there be a precise set of what must be be done till 19 May and 23
or is it decided based on whatever there is an active development? I assume
that to pass "final evaluation deadline" entire project must be delivered,
the two previous ones are supposed to be handled?
I am unsure what I should write as "detailed timeline: how do you plan to
spend your summer?". Should I declare when each feature will be finished? Or
is it about something else?
My proposal is available on
I would appreciate any feedback.

I think that it may be better to avoid forcing user to click in cases when
algorithm guessed right without additional data.

I am not sure. In the first case barrier should have either different layer
share node ("If a linear barrier crosses a highway, they must connect with
a node at intersection." - from Barriers article on wiki), and in the
road should have access tags. Though both cases are currently not
reported as a problem by JOSM validator (I filed ticket for the first case,
wiki is quite clear. Second seems to have no suggested solution on wiki,
maybe it should be discussed on tagging mailing list).

Added as part of defining route types ("improving definitions of route
to handle tagging variations").
> - Deal with features intersecting without nodes when they should block
I think that all cases like this are mapping bugs and should be reported
by JOSM validator (expecting every single router to parse thing like
no-go areas instead of checking access tags on roads is IMHO a poor idea).

Added to proposal as "implicit way splitting (for nodes that are in
the middle of way), with minimal required user action"
> Make a proper Undo (This one being particular important)
I am confused here, there is probably no need to revert way selection.
Is it about implicit splitting requested during selecting route? I added
note about this.
> Maybe cope with runtime and/or space constraints
I mentioned it in the new proposal version ("algorithm that will find
suitable connection in acceptable time, without too high memory usage").

quite large sub-editor).
I am not sure is it necessary, I thought that types would be edited like
rules. Possible to do, but 99,9% of users never needs to do it and others
may simply edit text file.

the central JOSM wiki repository, store in local user preferences).
Is is about distributing plugin or is it about how it will work? Or maybe

Now "making translations possible" is mentioned while discussing interface.

OK, I will rework proposal to indicate that it is intended to start as a
and mention integration into JOSM trunk as potential future goal.
Should I mention public transport plugin in proposal as source of this idea?
