Hi, Orion doesn't store own context. This policy is right, because if your context is composed by many attributes, and you update it, any second ... after few days (for example) the internal database (mongo) of Orion will became full and your service will fault.

To store the context you can use the Cygnus adapter and you can chose, for your app, the right storage system (ex. mongo, mysql, ckan, cosmos big data, etc...) that it depends how much data you want to manage.
