SQLite data dictonary: Index.sqlite and DocumentUsage.sqlite

Dear community

I have previously build a data warehouse based on the Targit AUX db, but this contains log-trans-data only.
I am missing master data/dimension data with no activity. For instance a complete list of documents, cubes, dimensions.

I am trying read information from the sqllite files in the targit server folder. My guess is that they are used for the new insights feature.

Index.sqlite
DocumentUsage.sqlite

Does anybody have some documentation that describes the data models?

One thong i particular are looking for is the version of the Targit document.

Best regards
