  11. Need of QVT DSL and Tool Families • [N1] Functionality viewpoint: variation on QVT DSL properties by project. • [N2] Process viewpoint: variation on processes by project, by methodology. • [N3] Language viewpoint: Variation of “abstract to concrete syntax” transformation, for low and level languages. • [N4] Design and implementation viewpoints, variation in function of architectural or non-functional decisions. • [N5] Capitalization viewpoint, managing platform variability (standards, languages, frameworks, tools). • [N6] Reusability viewpoint, different QVT DSLs can share common features. Managing common assets which can be reused in different QVT DSL contexts.  Complex but mandatory for meeting QVT DSL variations expected from project requirements Research & Technology

  12. A QVT DSL = a Domain • A QVT DSL is a Domain • Reusing product line experience • Managing QVT DSL domains • Managing QVT DSL core assets • Having a production method • Strength of this reflexivity: auto-consistency • End-products are built in the same way than development tools Research & Technology

  13. Core Asset Management • Kinds of core asset: • QVT DSL domain at the D2, D1 levels • QVT DSL tool description • Patterns, generators, frameworks, tools • QVT environment (QVT M2, platform descriptions…) • Managing core asset evolutions: • On domain • On Feature model • On Architecture • Production Plan Research & Technology

  14. Producing QVT DSL Tools: Where is the variability? How to manage variability? Product Production • Production Plan: describes how to manage production of product from core assets. • Takes into consideration: production method of each asset, linkage among core assets, product line constraints • Declaring how to fit into product production contexts Research & Technology

  15. Issues • Unified architecture of QVT DSL and Tool • Adopting a reduced number of QVT DSLs, a tree-organization with few bridges, and reflexivity according to the 3-level architecture principle. • Building flexible and consistent QVT DSL workbench • Same ergonomics and logic of action in function of the selected features. • Maximizing automation of product production • Required at a managed maturity model level • No standard for product line • Variability: restricted to company usage Research & Technology

  16. Agenda • Issue • Case Study of View DSL: Diagram DSL • Families of QVT DSL and Tool • Conclusion and Future Work Research & Technology

  17. Conclusion & Future Work • Conclusion: • Proof of concept: Production improvement with Diagram DSL • Need of families of QVT DSL and Tool • Considering QVT DSL as a domain and reusing product line experience • Next step? • Emergence of customized QVT workbenches with DSLs • Future Work: • Development of a QVT DSL factory integrating variability Research & Technology

  18. Questions Research & Technology
