Aim: Engineering the production of software

• Raise the abstraction level to the domain levelUse domain languages for representing knowledgeSeparate the knowledge from the implementation technologiesInvolve domain experts in the development process

• Bridge the Execution gapRewrite programs into models and model transformationsUse generators to stay up-to-date with current technologies

• Bridge the Data gapSpecify the data formats using the data integration languagesLet the integration tools generate the metamodels and parsers


Whole Platform Components

• Whole Language FrameworkCommon infrastructure for languages and toolingA Java library for Language Oriented Programming

• Whole LanguagesA set of languages acting as a familyModeling, data integration, and transformation languages

• Whole Language WorkbenchA development environment to program at the domain levelBased on Eclipse and GEF


Usage Scenarios

Three Software Product Lines are supported:

• Language DevelopmentDesign and implement a DSL or a GPL

• Data IntegrationLoad, Transform, and Store data sources

• Code GenerationPerform generative tasks

Alternatively, write your own Software Product Lineswith a Language Oriented Programming style


Language Development

• End-to-End Language definitionStructure, persistences, notations, and toolingMetamodels, validators, normalizers, interpreters, translatorsContent assistants, generators, refactorings, analyzers

• Very short and iterable development cycleLive definition and deploying of languages (including behavior)Jump start with generic notations and persistences

• Smoother transition to model driven developmentThe Language Framework for programming andthe Language Workbench for modeling


Models DSL to define Metamodels

FromsimpleDSLs

to full GPLs


Generic Notation: AST RightStart with a generic notation … then write a specific one


Generic Notation: Tabular TreeStart with a generic notation … then write a specific one


XML Generic Persistence


Java Generic Persistence


Actions DSL to define Tooling

Write,deploy

and try


Data Integration

• Wide range of data formats supportedXML Schemas, Grammars, DataBase Schemas, Java

• High level of automation reachedWrite or import the specification of a data formatGenerate the metamodelGenerate the data-to-model and model-to-data transformation


Grammars DSL to specify textual formats


Grammars DSL in actionDucati Marlboro Team Ducati Casey Stoner 01Marco Melandri …

Parse and unparse

From textto model and back


Workflows DSL to compose activities into processes


Code Generation

• Model-to-Model transformations

• Domain specific notations and tooling for all of the languages involved in a transformation

• New Domain Specific Languages

• The SQL and XPath feeling and (almost) semantics


Artifacts DSL to manipulate workspace and the file system


Queries DSL to perform queries and transformations


Javatemplates

and helpers
