What is SolFa?
• Objective:
Tool for mass-producing software with flexibility
Support for complex generations
• Used techniques:
Generative technique: M2M, M2T, T2T, T2M transformations
Product Line: capitalization and customization of core development
DSL (Domain-Specific Language): Facilitating software
development

Position of SolFa in Eclipse
• SolFa is a Model-Driven Development tool
• The SolFa foundation is fully Eclipse-based:
Non-UI (JDT, PDE, Core), UI (SWT, JFace, Forms, Eclipse UI)
EMF-based: Ecore, EMF Query, Validation, Transaction
Transformation: JET, EMF Mapping
• Purpose regarding component viewpoint:
Not a new transformation engine or DSL editor
Integration of available tools for software generation
Introduction of needed formalism (e.g., generation pattern) and
mechanism (e.g., generation orchestration)
• Purpose regarding user viewpoint:
Creation of off-the-shelf factories, common and specific to
different user communities

Why SolFa?
• Need#1: Factory Component
Unit of generation with a clear objective of generation
Unit of generation with a clear contract
Explicit declaration of generation data organised by viewpoints
Orchestration of the generation with a production plan
Assembly of factory components
Delegation
Creation of heterogeneous and complex generations

Why SolFa?
• Need#2: Exchange of Factory Components
Capitalisation and reuse between projects
Definition of Factory Component portfolios, .i.e. sets of FCs with a
common objective

Features of SolFa Engine
• Current state:
Edition and execution of factory component
Declaration of generation data organised by viewpoints
Assembly of factory components and generation orchestration
Generation performed by Java tasks or patterns
Pattern:
Example of viewpoint, with its own language and execution mode
Pattern inheritance for generation customisation, e.g. EMF generation
Provided: help, tutorials
• Future work:
[Started] Combination of Factory Component generation
Pattern: Supporting other M2T engines than Jet1(e.g., Jet2, xPand)
Supporting complex orchestrations
Extensibility: ability to plug generation viewpoints

Features of DSL Factory
• Current state:
Implementation of a DSL family portfolio:
Generation of a DSL from a DSL model and a DSL factory
Addressing common Query model needs, e.g. helper definition,
test, document, diagram generation
Common features:
Foundations of an abstract syntax:
For tool-independence, queries are modelled and actions are generic
Definition of reusable DSL pieces, recursion…
Generation of target artefacts from a DSL and FCs
• Future work:
Concrete syntax/Notation: Graphical-based on GMF
