scope:

The primary purpose of the multipart standard ISO/IEC 19763 is to specify a metamodel framework for interoperability.

This part of ISO/IEC 19763 specifies the metamodel that describes a facility to register administrative information and selected metadata about process models. The metamodel specified in this part of ISO/IEC 19763 is intended to promote semantic discovery and reuse of process models within/across process model repositories. For this purpose, it provides selected metadata and common semantics of process models created with a specific process modelling language, including Business Process Model and Notation (BPMN)^[1], UML (Unified Modelling Language) Activity Diagram^[5] and EPC (Event-driven Process Chain)^[7], etc. The metamodel can help discovery of the function and composition of a process, and promote reuse of its components at different levels of granularity. Figure 1 shows the scope of this part of ISO/IEC 19763.

The following are outside the scope of this part of ISO/IEC 19763:

- details related to modelling notations or descriptive languages of process models;

- runtime environments or implementation platforms for executing
