@johanemilsson: Great!

Do you know any way to download all embassies in one file for JOSM? I used Xapi before but I now it seems to be broken… (e.g. timeout error or no version tag etc.)?

It's done! I switched all country codes to upper case.

skela: Okay, that's right (although you mixed up upper and lower case). But I think people know that countries not languages have embassies :-)
In future embassies should be tagged with upper case, that's clear.

Hm, I think you are right. I'll do it in future with upper case.

"from_country" was my own proposal...

Much more users used "country" so I changed too. In the end it is technically very simple to change that back but to add ANY country code wasn't that simple (1,5 days for me).

@ThomasT: Ganz meine Meinung. Per pedes rules.

@FK270673: "so oft wie möglich"
In Städten (da hat OSM bisher die meisten Daten) ist Erfassung zu Fuß sehr gut möglich. Über Land ist es etwas anders, aber wünschenswert bleibt der sparsame Umgang mit dem Auto trotzdem.
