Eclipse 4diacWiki/Development/Detecting Model Inconsistencies in 4diac Models with OCL
Revision as of 05:06, 27 May 2020 by Unnamed Poltroon (Talk)
Overview page of GSoC 2020 Project
The aim of this project is to develop OCL constraints and well-formedness rules to the metamodels of 4diac in order to improve the usability of the IDE.
Contents
Milestones
Requirement specification
- Precise and traceable requirement list for rules which should be validated on the Ecore models
- Assigning the requirements to OCL constraints to facilitate traceability
- OCL constraint types: invariant, pre- and postcondition, derived element, operation contracts
- Format: Table format
- Google Sheet
Improving 4diac Ecore models
- Adding new elements (e.g. classes and helper operations) to the Ecore models to facilitate the introduction of OCL constraints
- Making suggestions for improvements on the Ecore models (without side-effects!)
Validity view for displaying validation results
- Displaying the violated OCL constraints and the problematic model elements in a user-friendly way
- Modal window? Something like the errors and warning view? Customizing built-in OCL errors view?
- Highlighting the problematic model elements in the model editor
Implementing OCL constraints
- Developing the OCL constraints and well-formedness rules based upon the requirement list
- Testing the newly implemented features and constraints
