The App Composer Translator stores in a local database all the translations and suggestions. This includes translations of applications, suggestions from other translations or from cloud services, historic of who wrote what, etc. However, so as to avoid Shindig contacting the App Composer (located in other university) for each translation of each application, we also have a MongoDB database outside the App Composer institution. The App Composer is responsible of pushing the translations to this MongoDB database. Ideally, the MongoDB would be located in the same institution as Shindig (so as to avoid calls to a Cloud service only for the translation), but at this moment it's located in an cloud basis at mongolabs.com.
Therefore, in this page you will find both what is stored in the App Comoposer database and also what is stored in the MongoDB database.
This is what is used by Shindig.
