The document discusses modeling with Eclipse. It defines what models and metamodels are, and explains that Eclipse Modeling Framework (EMF) allows defining and manipulating models. EMF can generate Java code from models and provides editors to work with models. Various Eclipse projects like GMF and Xtext allow graphical and textual modeling and code generation from models.

- 3. Some theory
- 4. What is a model ? A model is a description of any thing ( entities, issues, domains...)
- 5. You describe and manipulate your model with a meta model or a metalanguage.
- 6. What does a metalanguage look like ? Here are some representation of the JBI « Component » class. If we have the model of a Component : A « Component » class is its metamodel
- 7. These representation are its meta-meta-model UML Java Ecore XSD
- 8. What can you do with your models ? ...To be continued... CRUD ! Store ! Version ! Transform/Convert ! Visualize. Use them to generate stuff.

- 10. « As a software developer/architect, I understand the issues. But what about concrete solutions ? Methodologies ? Technologies ? »
- 11. 72 projects at Eclipse.org « The Eclipse Modeling Project focuses on the evolution and promotion of model-based development technologies within the Eclipse community by providing a unified set of modeling frameworks, tooling, and standards implementations. »
- 12. Can generate Java API for models.
- 13. Provides powerful introspection and code genericity thanks to its meta-comprehension and its « EObject ».
- 14. Provides (de)serialization of your models to files, transactional edition, notification support...
- 15. At runtime, your EMF models do not require Eclipse .
- 16. Generates and provides Eclipse-based editors for your models.
- 17. Generates and provides GWT-based editors for your models.
- 18. EMF Facts EMF can run on : EMF is lightweight EObjectImpl is just 12 bytes bigger than java.lang.Object
- 19. Demo 1 : EMF Ecore
- 20. Demo 1 : EMF Generated Java API + EObject API
- 21. EMF can be a piece of solution for various use-cases
- 22. Editors EMF provides extensions to create efficiently Eclipse editors for your models with (among others) : Validation
- 24. Databinding myObject.eGet(field) / myObject.eSet(field, value) ;
- 25. Demo 2 : Editors Generated by EMF Available for
- 26. Demo 2 : Editors Home-made editor
- 27. Graphical Editing – Runtime APIs « Classical » MVC « Runtime » MyDomainObject (extends EObject) Draw2d Figure GMF IGraphicalEditPart
- 28. Demo 3 : GMF Editor
- 29. Graphical Editing - Generators « Tooling » Semantic Model (ecore) GMF Diagram Model GMF codegen Diagram code Mapping
- 30. Demo 4 : GMF Tooling
- 31. Textual editing - DSL Semantic Model (ecore) Xtext grammar Xtext codegen (MWE) DSL parser DSL text editor (Implicit) Mapping
- 32. Demo 5 : XText
- 33. All this uses EMF ! Whatever representation you use, you are still using EMF to manipulate your models... Then...

- 36. Generate any kind of text Xpand JET A2 A1 Meta A M2T Just apply Blah-blah <%model.name%> Blah-blah A1 Blah-blah A2
- 37. Example : GMF Tooling uses XPand
- 38. M2M : Model to Model A2 B2 A1 B1 Meta A Meta B Tools to convert and transform models between different metamodels. QVT, M2M Just apply

- 42. What to remember ? You already use Model-Driven approaches
- 43. EMF is a very powerful library to create your (meta)models
- 44. For all Modeling issues, « There is an Eclipse project for that ».

Editor's Notes
- #2: Hello, Thank you Mickael Istria, Eclipse RCP/Plugin Developer at PetalsLink. 3 years commitment on Eclipse committer on GMF-Tooling User and contributor to lots of Eclipse project(modeling et al)
- #6: * On choisit son « meta » en fonction du use-case * On est toujours le meta d'un autre * « meta » est un mot relatif a la ou on observe.
- #7: * Validate, serialize, compare...
- #13: * Show model * Show ecore_diag * Generate .model * Show generated classes
- #14: * Show client * Show code * Run -> Does not depend on Eclipse, pure POJO * show generated file
- #16: * EEF : project dedicated to create model editors efficiently – just in a declarative way.
- #17: * Eclipse RCP, RAP, GWT * Generate .edit * Generate .editor * Open new Eclipse * Create a project, a file, edit Zoo * Import previous file, show zoo
- #18: * Open Editor + XML editor * Edit « endpoint », Save, Show XML * Ctrl-Z, Ctrl-Y * Show Eclipse « Demo » task with the databinding line * EEF : a new Eclipse project dedicated to this use case
- #20: * GMF customization thanks to high level APIs * Best modeling product
- #21: * Writing a whole editor can be long and difficult * Use generators to generate a first version, and customize after
- #22: * Show GMFMap * Add Top Node Water/child Fish * Show GMFGraph -> Figures desc * Show GMFTool -> Palette desc * Generate GMFGen (add org.eclipse.gmf.runtime.lite.svg) * Generate Code * Show
- #23: * Generates a (de)serializer for your DSL * Can be embedded in any Java App where EMF runs * Think about a language grammar : Model is AST, Xtext offers parsing, only execution need to be implemented
- #24: 5min30. * File > New > Xtext Project from Ecore Model -> org.eclipse.modeling.demo.zoo.dsl -> org.eclipse.modeling.demo.zoo.ZooDSL -> zoodsl * Show default grammar ~ Json * Replace with my Grammar -> Show mapping : implicit based on name and {...} * generate editor for « zoodsl » : May ask for ANTLR * Create file « myzoo.zoodsl » - Show completion, validation * Think about a java grammar
- #26: * Diagram already exists * Synchronization on « save » * Still work in progress * UML dream become true. * Think about Java grammar + UML class diagram
- #27: * Use case : generate web page * « One-way » Xtext * Batch * 2 different styles : Template ( ~jsp/php ) ; Rules
- #28: * Go to plugins view * Import as source « org.eclipse.gmf.codegen » * Show Editor.xpt -> Show how easy it is to navigate in EMF objects with « :: » Xpand is not the best ! Acceleo is better but I don't know it enough to demo it ; and you understood the point;)
- #29: * Use cases : -> Assuse Meta1 is zoo, and Meta2 is XHTML => generate XHTML page -> Assume Meta1 is Zoo from Berlin and Meta2 represents Zoo from Lyon. A european law says « everyone must work like Lyon' s zoo ». Then just transform/convert
- #30: * Show metamodel * Highlight difference -> Containement is not the same -> Class name are different -> No more name -> Containement of plots using a specific type * Show transfo : Rules -> For each element, apply a rule * Execute transfo, show results * Say that this transfo applies on models, not on files ! Then you can transform Xtext-based models as well.
- #31: * Only a few use-cases were presented
- #32: * CDO-Dawn -> Collaborative * Teneo -> JPA, Hibernate pour les modeles (Eobject)
