[josm-dev] Custom K/V Tags in MAPCSS?

[Alex Rollin]

Hi!

Let me try again, I am sorry I am not giving the right information.

We work with OSM!  You can check out our city on the map:

http://www.openstreetmap.org/#map=13/-6.5988/106.7778

We do a LOT of tracing and we also add a lot of POIs.  We have a very nice
JOSM Style that works very well.

However, we also use some local OSM files.  The example is JULY_SURVEY.osm
(a local OSM file, saved on the desktop)

In the survey file we put some points that have key=oursurvey
value=information

Our issue is that the MAPCSS in JOSM refuses to style this data.  We assume
this is because it is a custom key.

This is the style we are trying to use:

node[oursurvey=information] {
    icon-image: "icons/triangle.png";


This common key DOES work :

node[amenity=information] {
    icon-image: "icons/triangle.png";

This ACTUAL key also works:

node[tourism=information] {
    icon-image: "icons/triangle.png";

But, why can't we use a custom tag?  If we use an OSM tag, there is a
chance we will accidentally upload this data, which is just some
housekeeping data, and not good data for the OSM database.

This seems like a bug, that the MAPCSS engine in JOSM won't recognize a
custom key.

I highly recommend you try it for yourself!

I just added a JOSM ticket because I must think after so much testing that
this is not desired behavior. It seems the folks here think I have some
kind of data or issue making a style.  No!  I have a VERY long MAPCSS file
with lots of POI tags working very well, really!
