FOSS translation tools? English to Spanish, Spanish to Latin, Latin to Icelandic, etc
 

Does there exist some standard framework for translations in the FOSS world? Not a specific tool to translate from one language to another but something wich is designed so that new languages can be added to it easily.

What's the status of translation tools in the FOSS world? I'm interested in using a tool to translate English to Icelandic and Icelandic to English, and/or work on adding Icelandic to some standard framework.

EDIT
I'm also interested in a English-Icelandic, Icelandic-English dictionary, which is not designed to translate whole texts but to translate single words, again Icelandic does not have to exist in this tool but it would be interesting if the tool is some kind of a standard framework wich new languages can be added to.
