2. Case Study of View DSL: Diagram DSL
 [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

Need of QVT DSL and Tool Families
A QVT DSL = a Domain
 A QVT DSL is a Domain

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

Kinds of core asset:
Product Production

Takes into consideration: production method of each asset, linkage
among core assets, product line constraints
 Declaring how to fit into product production contexts
Producing QVT DSL Tools:
Where is the variability?
How to manage variability?

 Production Plan: describes how to manage production of
product from core assets.
Issues

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
