• WP Leader Star
• Speaker Sophie Monties

2
Implementation first step

• Inventory of the case tool components
• From user-usable components
• To target systems

3
The schema editor

• Architecture (just an intuition)
• Iterative project lifecycle
• D11 improves on D10
• Final version of the schema editor will improve
  on D11
• Result
• A prototype

Editor design guidelines

• Simplicity and attractiveness
• Each concept has to be
• Distinguishable from the others
• Clear
• Directly visible and perceptible

6
Leading ideas

• Freedom and flexibility
• Simple actions
• Text
• Sketch
• Less simpler actions
• The relevant Properties Window
• and a map for large schemas

7
Design features

• The spatial and temporal dimensions
• Support of multi-representation
• Orthogonality
• Any Structural concept
• Any Object
• Any Relationship

8
Visual aspects

• The Mads concepts
• Schema
• Representation
• Inheritance
• Entity
• Relationship
• Role and maybe
• Temporality Lifecycle
• Spatiality Geometry

Transformation module

• To each Mads concept, 1 rule is associated
• and it becomes more closed from Oracle

15
Oracle Wrapper

• To each remaining concept, 1 rule is associated
• and it becomes expressed in Oracle

16
Schema editor analysis

• Data structure as close as possible to the
  meta-model
• Implementation around the data structure
• Modularity
• Flexibility
• Extensibility
