Abstract: Embodiments are directed towards concurrent evaluation of large rule sets with conditions. A rule compiler may receive rule sets that include rules for policy management. During compilation, root nodes may be generated that include the rules and set to the current node in during the building of a decision tree. Next, the most common operand and a condition from the rule set may be determined. Evaluators corresponding to the most common operand and its condition may be generated. Each evaluator may include transition points pointing to other nodes in the decision tree. If two or more rules remain a node, the rule compiler may generate another node to process the two or more rules. If a transition corresponds to a single rule absent any condition, the rule compiler generates a match node. Completed decisions trees are deployed for execution in a policy engine.

Abstract: A method and apparatus that uses a hypermedia approach to managing distributed objects. A first embodiment of the present invention uses the World Wide Web hypermedia system. A user initializes browser software that allows the user to browse and change various attributes of objects in the system. The browser communicates with a server that includes an http adapter and a gateway. The gateway can access objects in the system and generate HTML code in accordance with the objects. One embodiment of the present invention uses hierarchical tree-oriented objects. These objects are “self-describing” (also called “introspective”). The server queries the objects in response to the queries from the browser and each queried object responds with information about itself. In another preferred embodiment, the server initiates queries of the objects and retains this information for use in responding to later queries from the browser.
