1. A computer-implemented method, implemented in a computer system, comprising: creating a business process model, using a processor of the computer system, wherein the business process model comprises a set of primitives, and one or more associations, the set of primitives comprise at least one of a control flow primitive, or an annotation primitive, each association of the one or more associations is configured to define a relationship between a plurality of primitives of the set of primitives, said each association of the one or more associations is classified by an association type, and the creating comprises receiving business process data, wherein the business process data is configured to be received at a business process model creator, and the business process data is for the business process, and creating an object for the business process data based on the business process model, wherein the creating the object is performed by the business process model creator; and storing the business process model in a business process model repository, wherein the business process model repository is stored in a storage device of the computer system, the business process model repository and the business process model creator are coupled to one another, the business process model is a meta-model of a business process, the business process model repository is configured to provide a view point of a plurality of view points of the model to different classes of users, and the view point is a view of the business process.
