2 Deploying Eclipse Modelling on an industrial scale with software factories

SolFamde solution factories Agenda

• What is SolFa?, Why SolFa?• Demo• Summary


SolFamde solution factories 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


SolFamde solution factories 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


SolFamde solution factories 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



• 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



• Need#3: Abstraction

SolFamde solution factories 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


SolFamde solution factories 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
