Method and apparatus for building metadata driven software development kit

A customization system for customizing a target application having a plurality of entities, the system comprising:

• an entity metadata module adapted to store an entity of the plurality of entities in metadata format;
• an entity definition module adapted to access the metadata definition of the entity;
• a base class module adapted to store a set of base classes to use metadata for the entity, the base class module further adapted to manipulate a property of an instance of the entity and to construct a query to influence the instance of the entity received from the target application;
• and
• a serialization module adapted to serialize the base classes to generate an xml message to be communicated to the target application.

A computer-readable medium having computer-executable instructions for performing a method of customizing a target application having a plurality of entities, the method comprising:

• (a) defining an entity of the plurality of entities in metadata format;
• (b) providing a customization system with access to the metadata definition of the entity;
• (c) providing a set of base classes to use metadata for the entity to perform at least one of:
• (1) manipulating a property of an instance of the entity and (2) constructing a query to influence the instance of the entity received from the target application;
• and
• (d) serializing the base classes to generate an xml message be communicated to the target application.
