Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). For brevity, this Standard will be referred to as \"CAN/CSA-ISO/IEC 19763-8\" throughout. At the time of publication, ISO/IEC 19763-8:2015 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC. 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 a metamodel for registering the role and goal models of users of services and/or processes. The metamodel that this part specifies is intended to promote the reuse of goals by roles within/across role and goal model repositories, and further promote services selection across service model repositories based on goals. For this purpose, it provides administrative information and common semantics of role and goal models created with a specific role and goal modelling language, including Goal-oriented requirements modelling (i*) [1], Keep All Objects Satisfied (KAOS) [2], Non-functional Requirement Framework (NFRF) [3], Business Motivation Model (BMM) [4], Reference Model of Open Distributed Processing (RM-ODP) [5] etc. Figure 1 shows the scope of this part. In this figure, \"register\" refers to the registration activity of registering administrative and descriptive information for role and goal models into the role and goal model registry based on the metamodel specified in this part of ISO/IEC 19763, as well as the mapping between source role and goal metamodels and MFI Role and Goal metamodel.
