Motives and Goals

Integrated Information Systems CASE Tool

(IIS*Case)

– Model driven software tool that provides generation of executable application prototypes – Provides the generation of database schemas and fully operational application prototypes – We have created a number of modeling, meta- level concepts and formal rules that are used in the design process

in order to provide design of various platform

independent models (PIM) by IIS*Case

GMLD 2012/Vladimir Dimitrieski 3/22

SLIDE 4

Motives and Goals

Current research

– IIS*CDesLang

textual DSL
developed using attribute grammars
formalization of PIM concepts

– modeling in a formal way

formal correctness and semantical analysis of

models

GMLD 2012/Vladimir Dimitrieski 4/22

SLIDE 5

Motives and Goals

Current research

– MOF approach

Ecore

– Eclipse’s implementation of MOF

specification of PIM concepts
developing textual DSL

– MetaEdit+ approach

GOPPRR
specification of PIM concepts
developing graphical DSL

SLIDE 6

Motives and Goals

Main research goals

– Comparison of Ecore and GOPPRR

concepts used
ease of use

– Basis for the better understanding of the meta- languages

further development of textual and graphical DSLs

SLIDE 13

Ease of use

GMLD 2012/Vladimir Dimitrieski 13/22

SLIDE 14

Ease of use

Restricting meta-concept’s number of

instances in a model

– GOPPRR allows the definition of object’s possible instances number

{0}, {1} and {N}

– Ecore does not have this option

possible solution – use of OCL

GMLD 2012/Vladimir Dimitrieski 14/22

SLIDE 15

Ease of use

Mandatory properties

– GOPPRR has regular expressions

powerful mechanism

– value patterns

experienced users
„.+“ for mandatory property

– Ecore has cardinalities

easy specification of mandatory properties
has an upper bound

GMLD 2012/Vladimir Dimitrieski 15/22

SLIDE 16

Ease of use

Relationship attributes

– One of the main advantages of GOPPRR – Referenced form type modeled in both meta- languages

CallFT vs several EClasses

SLIDE 19

Further research

Some ideas/goals

– Code generator

import the code into IIS*Case

– Mapping between the meta-models using GOPPRR and Ecore specification

development of our own bridge
using EMF-MetaEdit+-Bridge
transformations between models in EMF

– Epsilon or Xpand

– Textual and visual editors

over the same IIS*Case repository

SLIDE 21

Conclusion

Ecore

– EMF only for abstract syntax development – De facto standard – XMI

GOPPRR

– MetaEdit+ environment for graphical DSL creation – More expressive power – Easily extensible graphical representation
