Proposal Of A Generic Visual Critic Authoring Framework

1. Proposal Of A Generic Visual Critic Authoring Framework By: Norhayati Mohd.Ali PhD Candidate [1st Year : PhD] Supervisors: Prof.John Grundy & Prof.John Hosking

2. Content • Introduction • Research Objective • Literature Review & Motivation • Approach • Methodology • Research Progress • Conclusions

3. Introduction • Integrated support tools have been developed to support designers in developing complex software/systems • One of the components of such integrated support tools Critics • Focus of researchThe use of critic tools in software development

4. Introduction • Critic tools have been used for many domains. • Critic tools: • detect potential problems • Give advice and alternative solutions • Possibly automated/semi-automated design improvements to the end-user

5. Research Objective • The objective of this research is to develop a generic visual critic authoring framework embedded within an end-user oriented domain specific visual language meta tool • This will allow tool critic support to be developed in parallel with the tools

6. Literature Review • Critic-support tools • DSVL • Meta-tool & meta-model concept • Visual modelling environment • OCL

7. Critic-support tools Table1:Critic tool research in SE domain Table 2:Critic tools in other domain

8. DSVL • The domain-specific visual language (DSVL) are graphical notations specially devised for the specific needs and knowledge [J de Lara, H.Vangheluwe] • allows someone who is a domain expert to use the visual language as an application development tool for the domain. • defined by a modeling language(meta-model) that defines a set of possible languages(models) and provides a basis for generators.

9. Motivation • Most existing critic tools use representational approaches that are: • complex to express • requires deep programming understanding • difficult for end user designers • No visual critic authoring tool • Opportunity to design & develop a visual critic authoring framework

10. Approach • Based on the “Three examples” pattern of the Evolving Frameworks Pattern Language [Roberts,D & Johnson,R. ] • Generalize from the three examples to a generic visual language and support environment

11. Methodology Develop an initial prototype – explore problems & issues Identify a set of initial requirements for a visual critic tool LR-critic tools, compare & analyse y1 Identify a core set of building blocks needed for a generic critic authoring framework Design three examples of visual critic tools with different domains y2 Evaluate the visual critic authoring tool: -construct a prototype systems and examples -Test against design examples -conduct end user evaluation Design & implement the visual critic authoring framework y3

12. Research Progress • Analyse and compare the critic-based tools (based on table 1) • List critic specification • Apply Marama formula designer – as a stepping stone

13. Research Progress • Critic Specifications

14. Research Progress Example of critic: Naming Critics concerned with Class, Attribute & Method

15. Research Progress Example of critic: Structure Critics concerned with the Relationships between Classes

16. Research Progress • Visual Critic’s metamodel

17. Conclusions • Through this research, we will provide proofs of the fact that such a DSVL for critic-support tool will assists the end-user software designers to express critics naturally and efficiently at the meta level
