Government Reference "Modello" is the core GRM Foundation project.
We maintain an .archimate file containing the OMG's Goverment Reference Model and other .archimate files for GRM (unofficial) localizations. GRM is compliant to TOGAF (The Open Group Architecture Framework) and it is modeled using the Archimate standard modeling language. For example, the GRM.it.archimate model contains the Italian localization of the GRM and the GRM.en.archimate file contains the original model in the English language.
Everybody can contribute adding new localizations.
In addition, at the GRM Foundation, we maintain State-based instances of the GRM model (both in English and State mother tongue), based on the specific law systems of the different States. Those State-specific models are stored in State-specific .archimate files managed as State-specific branches of the project/repository. For example, the ITA branch of this project/repository captures the Italian specific goverment enterprise architecture based on the Sourceses of the Italian legal systems. Into the ITA branch you can find the GRM-ITA.it.archimate file -containing the model in Italian- and the GRM-ITA.en.archimate file -containing the same model in English-. In the State-specific models, the elements coming from the "standard" OMG/TOGAF Government Reference Model (GRM.en.archimate) are translated, but the original English name still appears between brackets; i.e.: in the GRM-ITA.it.archimate file the "Growth, Housing, and Environment" Business Function is translated into "Crescita, Casa ed Ambiente (Growth, Housing, and Environment)"
