At the Wikimedia Foundation I have been banging the drum for the use of standards. I made some friends and enemies in that way, but the overall effect has been good. Some fights are no longer fought because the result is clear from the start.
At Betawiki, we are developing an extension for MediaWiki called Babel. The tool is to be used on the user pages indicating the self assessed skills in the languages a person knows. The texts are shown in the language itself.
When we do not have a translated text yet, we are still able to use the native name of that language courtesy of the data available in the CLDR. The standard is not complete, and I asked if it was possible to change the data in our database. I was told no. "The data belongs to a standard and, the data should be improved at source".
I do agree with this sentiment. I have written to someone active in the CLDR if there is an interest in collaboration. I am happy and proud of this turn of events. I hope that we are welcome :)
