Abstract:
A computer systems includes a rule engine, one or more repository interfaces, and corresponding repositories. The repositories typically contain content or profile information about users. The rule engine provides rules in a uniform format which can be translated, through use of the repository interfaces, into queries specific for the corresponding repositories. Before translating the rules, context objects referenced in the rules are resolved and the corresponding attribute values are inserted into the rules. The resulting rule is simplified where possible because of the attribute values, so that only those queries that need to be made to a repository are made.
