Distributed scalable policy based content management

A distributed, scalable policy filter architecture for a content management system, comprising:

• a computer including a processor and a memory;
• a policy repository for storing a plurality of policies stored in the memory, the policy repository including an interface for allowing a content management engine run on the processor to retrieve the stored policies via a plurality of indexes of the stored policies, the indexes including a system trigger index and a condition index, each of the plurality of indexes being tied to a specific domain name in a directory;
• and
• the content management engine including,
• (a) a plurality of filters that act as policy decision points, the filters retrieving the relevant policies from the policy repository, the filters being adapted to retrieve and evaluate the policies via the interface of the policy repository, the evaluation of the policies by the plurality of filters to determine what system transactions are required in response to a content request;
• and the evaluation of the policies being performed in at least one of an outsourcing mode and a provisioning mode;
• and
• (b) a systems transactions processor that requires every content request to pass through the policy filters before it is processed.

A mobile content management system including a plurality of transient mobile devices, the mobile content management system adapted to generate its own internal transient policies, comprising:

• a computer including a processor and a memory;
• a mobile content management engine executed on the processor, the mobile content management engine generating internal transient policies in response to events within or external from the system, the content management engine including a system transactions processor and an event notification component, wherein the content management engine uses the generated internal transient policies to configure the behavior of the system transactions processor and the event notification component;
• and
• wherein the content management engine supports version control on digital content by instantiating transient policies which allows for a first mobile device to access the digital content and stops other mobile devices from accessing the digital content until the first mobile device returns the digital content.

A computer implemented method for defining and constraining a behavior of a shared, mobile content management system including a plurality of mobile devices in at least two separate security domains having periodic communications within the system, the computer including a memory, a first processor and a display, comprising:

• providing an admin console for defining, modifying, and managing declarative policies by separate security domain for the mobile devices on the display;
• defining the declarative policies based on a mobile policy model via the first processor, the mobile policy model dictating the declarative policies that can be expressed by the admin console;
• enacting the defined declarative policies without requiring the content management system to be restarted, reconfigured, or re-implemented via the first processor;
• providing an XML-based policy wizard definition language for defining policy wizards in the admin console that guide an administrator through creating and editing the declarative policies;
• providing at least one policy repository based on LDAP, the at least one policy repository having an interface and being adapted to store a plurality of declarative policies, the at least one policy repository having scalable and distributed capabilities;
• providing a second processor for policy enforcement, to determine which declarative policy applies to a particular transaction from at least one of the plurality of mobile devices;
• and
• distributing the declarative policies to the mobile devices via their respective security domains.
