Abstract
A framework is defined for property-based filtering for objects. The framework is independent of specific programming languages. Selection criteria is entered to match on the selected criteria and allow for searching for objects. Properties for objects are exposed as property sets and language specific projections of properties. The framework codifies strongly typed properties and property sets, projecting property sets generically on language specific objects, and a generic Boolean filtering system on objects or property sets. The framework defines property keys with type, property values, property expressions, and property filters which are a collection of property expressions which can be applied against property sets, property handlers, and language-specific projections of generic objects. The framework also includes a generic object programming model where objects expose a common interface whereby generic property filters can be evaluated against any object.
