Method and apparatus for managing a cache in a group resource environment

A computer implemented method for managing resources, said resources including content resources and people resources comprising:

• managing a plurality of nodes representing resources, said nodes including content nodes and person nodes, wherein the node contains a resource reference for referencing the resource;
• managing one or more links representing one or more relationships between the resources, said links including links between content nodes, between person nodes and between content and person nodes, each link comprising node references to identify the nodes in the relationships and an importance value to identify the importance of the relationship;
• providing an interface for selecting one of the plurality of content nodes or person nodes;
• and
• copying links that are to be adapted from persistent memory to cache memory and updating the link in persistent memory from cache memory based on a change criteria and the update of the link.

A system for managing resources, said resources including content resources and people resources comprising:

• means for managing a plurality of nodes representing resources, said nodes including content nodes and person nodes, wherein the node contains a resource reference for referencing the resource;
• means for managing one or more links representing one or more relationships between the resources, said links including links between content nodes, between person nodes and between content and person nodes, each link comprising node references to identify the nodes in the relationships and an importance value to identify the importance of the relationship;
• means for providing an interface for selecting one of the plurality of content nodes or person nodes;
• and
• means for copying links that are to be adapted from persistent memory to cache memory and updating the link in persistent memory from cache memory based on a change criteria and the update of the link.

A computer program product for processing one or more sets of data processing tasks, said computer program product comprising computer program instructions stored on a computer-readable storage medium for, when loaded into a computer and executed, causing a computer to carry out the steps of:

• managing a plurality of nodes representing resources, said nodes including content nodes and person nodes, wherein the node contains a resource reference for referencing the resource;
• managing one or more links representing one or more relationships between the resources, said links including links between content nodes, between person nodes and between content and person nodes, each link comprising node references to identify the nodes in the relationships and an importance value to identify the importance of the relationship;
• providing an interface for selecting one of the plurality of content nodes or person nodes;
• and
• copying links that are to be adapted from persistent memory to cache memory and updating the link in persistent memory from cache memory based on a change criteria and the update of the link.
