Its not common sense, its stupid. That way you make sure that your special
fixme tag is not seen by tools that look for the normal fixme tag.

The value for the fixme tag is a free-text note. You can just write:
"fixme=Not sure whether the name is right, verify maxspeed". Even better:
If you are not sure about the name and maxspeed, delete those tags. Then
its obvious that something is missing there and somebody will add it in due
course. No special tags needed.

We don't need a proposal for this. It is such common sense that
people do this already where it is appropriate (i.e. where more than
one FIXME is needed on a single OSM element) :

Would it make more sense to categorize by the tag? For example:
*FIXME:name=yes
*FIXME:maxspeed=verify that the entire road is 55 mph

As it happens I have just written this blog post to announce OSMI 
Potlatch compatibility:


http://blog.geofabrik.de/?p=96

Here's a direct example of using OSMI's "tagging" view (which highlights 
potential typos as well as any FIXME tags) in Potlatch:


http://www.openstreetmap.org/edit?lat=53.02178&lon=-2.65969&zoom=16&tileurl=http://tools.geofabrik.de/osmi/tiles/tagging/$z/$x/$y.png

You might want to use the "d" key in Potlatch to temporarily dim the 
data and/or switch off background dimming so that OSMI's messages are 
easier readable.


This is the early days of OSMI tiles in Potlatch and I'm sure we'll see 
improvements over time; feel free to suggest what you think should be 
changed or added.


Bye
Frederik

I don't think it makes it significantly more difficult, as fixmes
should have some kind of description of the problem.  Classifiying
them in the tags is just a more systematic way of doing that, which
makes them more amenable to higher-level tool use (e.g. someone could
write a program that identifies the areas with most density of
problems that need on-the-ground surveying... or even a route planner
that creates a route using highways tagged as approximate, for someone
to carry a GPS over, although the latter is probably stretching it a
bit).

It's not just ease of tagging things with fixme that counts (although
it should be easy, and a plain "fixme" should always be acceptable);
ease of using (finding and fixing) the fixmes is also important.

I think it's also helpful for people to be able to plan problem-fixing
surveys efficiently.

Commo fixme in the East midlands at least is
Fixme:stub for future suvey
Typically a path or bridleway where the end has been surveyed but the route
not traversed.  often these hasn't been placed to accuratly either (i.e.
Someone spotted it when passing without gps) so incomplete isn't accurate
either!

Whats the best way of finding these, the only one i have seen is the ito
analysis but they dont offer zooming in :-(

How about starting a convention of using a tag "fixme:survey_needed"
with the details in the value string?

The only other subtype of fixme that I can think of immediately would
be "fixme:incomplete", for long / hard-to-spot linear features such as
powerlines (where I've seen someone else was using fixme=incomplete
and have tried to follow that convention myself).

I like the idea of extending the NONAME layer to report fixmes, and if
we used a convention like fixme:survey_needed we could have a distinct
map symbol for that.

They should never be *automatically* tagged on the data itself.

>Only manually detected problems should be tagged with fixme.

I would add, however, that if an automated tool reported a problem and you
manually investigated it but weren't able to fix it immediately (or to
immediately determine that the tool is wrong), then you can tag fixme with
a note on your work so far.

For example,

FIXME=Do these roads join here?  Not clear on Bing imagery.  Survey needed.

That will be a useful note for somebody planning to visit the area later so
they can check this place if they wish.  But deluging the area with large
numbers of automatically generated fixme tags is not helpful, because anyone
can run the tool themselves to see that.
