Implementation Guidelines

Content Access Framework provides a common interface for applications to access content. It behaves as a switch between different Content Access Agents (CAA). This section describes the guidelines that are suggested for implementing client and server agents. However, these may not be appropriate for all agents.

Client-side

At the client-side, implement the following:

  • Implement the CAA ECom interface

  • Browse the contents of files

  • Retrieve attributes or meta-data from a file

  • Display a user interface or dialog for all functions requiring the agent to display

  • File recognition for client applications and Apparc MIME types

  • Marshall calls to the server-side

Server-side

At the server-side, implement the following:

  • Content encryption (protecting plaintext)

  • Content decryption (reading DRM content)

  • Manage, protect and store rights

  • Any potentially destructive operation, such as deleting content or rights

  • Notifications

  • Capability enforcement
