  1. Discussion about MFI-8: Metamodel for Role and Goal Registration Wang Jian, He Keqing, He Yangfan, Wang Chong SKLSE, Wuhan University, P.R. China 2009.11.18

  2. Motivation • In the development of local and distributed information systems, roles and goals are two important factors. • Roles can be used to identify the objectives of the system, and express the preferential requirements of users. • Goals provide a way for describing business processes at a higher abstraction level. • Effective management of roles and goals contributes to describing users intention and reusing information resources with greater granularity.

  3. Definitions from wikipedia A role or a social role is a set of connected behaviors, rights and obligations as conceptualized by actors in a social situation. It is an expected behavior in a given individual social status and social position. A goal or objective is a projected state of affairs that a person or a system plans or intends to achieve—a personal or organizational desired end-point in some sort of assumed development.

  4. Definitions in MFI-8 • A role is abstract characterizations of organizational behaviours and responsibilities within specified organizational context. • Description of roles will be helpful in characterizing goals in a more complete and correct way. • A goal is a descriptive statement of business intent of a user or an organization, and it can be viewed as an objective that the business system under consideration should achieve.

  5. Scope of MFI-8(1/2) • Specify a metamodel for registering users’ roles and goals in specific domains that can be used to describe users’ intention. • Define the decomposition and constraint relationships between goals. From resolution of Wuhan Meeting, September, 2008

  9. Registering role and goal models FOAF RM-ODP BMM KAOS Tropos

  10. FOAF(Friend of a Friend) FOAF is a machine-readable ontology describing persons, their activities, and their relationships to other people and objects. FOAF allows groups of people to truly open social networks without the need for a centralised database, which is an important contribution to the linked information system known as the Web.

  11. An Example Social Profile of an actor in MFI-8 “interacts” in MFI-8

  12. R G P Enterprise View in RM-ODP Enterprise specification determines the purpose, scope and policies for a system, which consists of roles and policies with respect to the reference point. RM-ODP: Reference Model of Open Distributed Processing

  13. Organization in MFI-8 Goal/ Decomposition in MFI-8 Actor in MFI-8 Role in MFI-8

  14. BMM (Business Motivation Model) • OMG’s BMM is developed from a business perspective • To develop a business model for the elements of the business plans before system design is begun.

  15. Metamodel of BMM Operational Goal in MFI-8 Goal in MFI-8 Role in MFI-8

  16. Metamodel of KAOS Role Goal/Personal Goal Decomposition/Constraint in MFI-8 Actor in MFI-8

  17. Metamodel of Tropos Actor and Role in MFI-8 Goal in MFI-8

  18. Future Work • Summary • MFI-8 provides a generic framework for registering descriptive information of roles and goals; • It aims to promote the reuse of information resources with greater granularity. • Future work • Harmonization with the other standards • Submit a CD version in Feb. 2010

  19. Thank you!

  20. An Application of FOAF-DOAC (Description Of A Career) Social Profile information of an actor in RGPS DOAC is a vocabulary to descriptive professional capabilities of a worker. Business people can search the internet to find a worker that fits their requirements and will be as easy as any search in Google. Other applications:Facebook, Twitter, etc

  21. Role in MFI-8 Functional Goal in MFI-8 Nonfunctional Goal in MFI-8 Enterprise specification determines the purpose, scope and policies for a system, which consists of roles and policies with respect to the reference point.
