Systems and methods include an application programming interface based on a first plurality of object attributes of a data structure, and a framework to update the data structure with a second one or more object attributes and associate the first object type with a first search method. The application programming interface is updated based on the updated data structure, and the framework receives attribute values and the first object type via the updated application programming interface, maps the attribute values to respective ones of the first object attributes and the second object attributes, and identifies and executes the first search method to generate a query of object instances of the first object type.
