MetaShare's general architecture

Important to note is:

  1. The end users interact with MetaShare’s web application.
  2. MetaShare’s web application only stores each customers’ unique MetaShare configurations (e.g. which filters and columns to display in the user interface).
  3. Documents and their metadata are only stored in the customers’ own Office 365 tenant.
  4. Documents are opened directly from SharePoint, never passing through the MetaShare application.
