Abstract

An embodiment of the present invention is a technique for translating a business rule. An operation for a rule to authorize a provision of information is created. A current container is established. A propositional expression in the rule describing the provision of the information is processed. If the current container is null, a context for the propositional expression is recorded as null, else an object type in the current container is recorded as a resulting context from the propositional expression.

Claims

1. A method comprising:

creating an operation for a rule to authorize a provision of information;

establishing a current container;

processing a propositional expression in the rule describing the provision of the information; and

if the current container is null

recording that a context for the propositional expression is null,

else recording that object type in the current container is a resulting context from the proposition expression.

2. The method of claim 1 wherein processing the propositional expression comprises:

setting the current container to be null;

establishing the context for the propositional expression in the rule; and

parsing the propositional expression.

3. The method of claim 2 wherein establishing the context for the propositional expression comprises:

else setting the current container to null,

else setting the current container to be the object type generated for the referent term.

4. The method of claim 2 wherein parsing the propositional expression comprises:

reading in logical order a role expression in the propositional expression if a propositional interrogative is applied to the propositional expression, the role expression being not a pronominal reference and including no definite article or expression of a specifically referenced instance;

if the role expression contains an indefinite article or has no quantification,
