3 Copyright © 2009 AtlanMod. All Rights Reserved Outline ► Introduction ► Overview of Microsoft “Oslo” ► EMF↔“Oslo” Interoperability ► Benefits of the Approach ► Concrete Problems ► Bridging Technical Spaces ► Current Results & Demo ► Roadmap ► Conclusion 10/12/2015 3

4 Copyright © 2009 AtlanMod. All Rights Reserved Introduction ► Modeling with Eclipse ► Core technology: EMF (i.e., abstract syntax) ► Transformation: M2M, M2T ► Concrete syntaxes: GMF, TMF ► Modeling with Microsoft ► DSL Tools ► Integrated in Visual Studio ► Not catching momentum ► “Oslo” 10/12/2015 4 ?

5 Copyright © 2009 AtlanMod. All Rights Reserved Overview of Microsoft “Oslo”: The Project ► “Oslo”: current code name for a set of future Microsoft modeling technologies ► May 2009 CTP already available ► Scope: Model-Driven Development and building of Model-Driven Applications ► Approach: Intensive use of data (i.e., models) and metadata (i.e., metamodels) 10/12/2015 5

6 Copyright © 2009 AtlanMod. All Rights Reserved Overview of Microsoft “Oslo”: The Environment ► The M Language ► “Intellipad” ► Extensible and customizable textual editor ► “M” language basically supported ► “Oslo” Repository ► Storage runtime built on top of SQL Server ► Some base domains (metamodels) provided (e.g., CLR, UML) ► “Quadrant” ► Configurable graphical tool for database data visualization  No transformation technology yet 10/12/2015 6

7 Copyright © 2009 AtlanMod. All Rights Reserved Overview of Microsoft “Oslo”: The “M” Modeling Language (1/2) ► “M”: modeling domains using text ► “M” as a textual DSL for dealing with the data types, the data instances and the language syntax ► 3 complementary languages ► MSchema (  Ecore) ► MGraph (  Resources + EObjects) ► MGrammar (  TMF) ► An automated mapping to databases 10/12/2015 7

8 Copyright © 2009 AtlanMod. All Rights Reserved Overview of Microsoft “Oslo”: The “M” Modeling Language (2/2) ► MSchema for modeling data types: ► Domain types ► Domain constraints ► MGraph for modeling data instances: ► Concrete data as “extents” (e.g., “Cars” which has 3 elements) 10/12/2015 8

9 Copyright © 2009 AtlanMod. All Rights Reserved EMF↔“Oslo” Interoperability: Definitions ► Data-Level Interoperability: metadata/data (i.e., metamodel/model) interchange between two or more environments ► Operational-Level Interoperability: model transformation interchange between two or more environments 10/12/2015 9

10 Copyright © 2009 AtlanMod. All Rights Reserved EMF↔“Oslo” Interoperability: Some Benefits of the Approach ► Multiple environment support ► Integration of different existing solutions ► Genericity (independence from the implementation technology) ► Reusability of already available resources ► Direct extensibility to other environments or formats (model transformation-based approach) 10/12/2015 10

11 Copyright © 2009 AtlanMod. All Rights Reserved EMF↔“Oslo” Interoperability: Some Concrete Problems (1/2) ► Platform: Java .NET ► API: EObject  Node (MGraph Object Model) ► Runtime storage: Java objects  Database ► Alternatives exist for EMF, notably CDO (database) ► Alternatives may be implemented for Oslo ► Default file storage/export: XMI  MGraph ► Alternatives exist for both 10/12/2015 11

12 Copyright © 2009 AtlanMod. All Rights Reserved EMF↔“Oslo” Interoperability: Some Concrete Problems (2/2) ► Metametamodel: Ecore  MSchema ► References: no built-in support for opposites ► Need to write constraints ► Type identity ► Same attributes  same type ► Mandatory “extents” specification ► Correspond to tables in the database ► MSchema inherits some relational concepts 10/12/2015 12

13 Copyright © 2009 AtlanMod. All Rights Reserved ► Oslo-based bridge ► Representing EMF-M2 in Oslo ► Transforming EMF-M2  Oslo ► Transforming EMF-M1  Oslo-M1 ► EMF-based bridge ► Representing Olso-M2 in EMF ► Transforming Olso-M2  EMF ► Transforming Oslo-M1  EMF-M1 EMF↔“Oslo” Interoperability: Bridging Technical Spaces: data-level 10/12/2015 13 Ecore DSL X P1 MSchema DSL X P1 MSchema DSL X Ecore DSL X M1 M2 M3 : both ways (but one is enough) Projection Transformation conformsTo EMF Oslo ?

14 Copyright © 2009 AtlanMod. All Rights Reserved EMF↔“Oslo” Interoperability: Bridging Technical Spaces: operational-level ► From the “Olso” forum ► “Generating Visual studio Test case from Mgraph” ► M2T ► “Any Transformation from XSD to MSchema”? ► “Is there any Antlr ---> MGrammar translator around?” ► “Oslo” needs M2M ► M2M/ATL may work with MSchema, but needs a specific driver plus a port to.NET 10/12/2015 14

15 Copyright © 2009 AtlanMod. All Rights Reserved EMF↔“Oslo” Interoperability: Current Results  ATL VM on.NET ► The ATL model-to-model transformation execution environment ► Dedicated ATL Virtual Machine (VM) ► Current implementation in Java/Eclipse ► Operates on EMF models ►.NET version of the ATL VM ► Developed in C# using the.NET Framework ► Operates on KMF models (a subset of EMF) 10/12/2015 15

16 Copyright © 2009 AtlanMod. All Rights Reserved EMF↔“Oslo” Interoperability: Current Results  Zoo of “domains” ► Library of “domains” modeled in “M” ► Automatically generated from the library of metamodels in Ecore format ► Using the ATL bridge at the M2-level ► Based on the “MSchema” part of the language (type modeling) ► Initial version to be improved ► e.g., opposite references are not represented yet 10/12/2015 16

17 Copyright © 2009 AtlanMod. All Rights Reserved EMF↔“Oslo” Interoperability: Current Results  Zoo of “domains” 10/12/2015 17

18 Copyright © 2009 AtlanMod. All Rights Reserved EMF↔“Oslo” Interoperability: Current Results  Zoo of “domains” ► The “AntScript” metamodel example: 10/12/2015 18

19 Copyright © 2009 AtlanMod. All Rights Reserved ► EMF-based bridge ► Representing Olso-M2 in EMF ► Transforming Olso-M2  EMF EMF↔“Oslo” Interoperability: Current Results  Zoo of “domains”: demo 10/12/2015 19 Ecore DSL X P1 MSchema DSL X P1 MSchema DSL X M1 M2 M3 Projection Transformation conformsTo EMF Oslo ATLTCS KM3 DSL X ATL

20 Copyright © 2009 AtlanMod. All Rights Reserved Roadmap ► Data-level bridging ► M2-Level (metadata/metamodels) ► Finalize & publish ► M1-Level (data/models) ► Implement ► Operational-level bridging ► ATL VM in C#/.NET ► Test and improve accordingly ► ATL VM to basically support Oslo “models” ► Adapt the lower layer to directly talk to “Oslo” (via the MGraph Object Model API) 10/12/2015 20

21 Copyright © 2009 AtlanMod. All Rights Reserved Roadmap ► Creation of a dedicated project ► Current situation: ► Library of metamodels in “M” language available from the AtlanMod website ► ATL VM in.NET available from the ATL Research branch of the Eclipse-M2M project ► Future: ► Where could this project be created? ► Eclipse.org, CodePlex.org? 10/12/2015 21

22 Copyright © 2009 AtlanMod. All Rights Reserved Conclusion ► Transformation missing in “Oslo” ► EMF and “Oslo” do not talk together ► Interoperability is possible at different levels  Solution implemented with AmmA: a collection of modeling tools from Eclipse.org ► Model transformation with M2M/ATL ► Textual modeling with TMF/TCS, ► Pivot metametamodel: KM3 ► Complex transformation workflow (ant tasks) 10/12/2015 22
