KB-powered modelling assistance and validation

9. - Visual editor for AADM
- Based on Sirius
- Form-based edition of nodes and policies
SODALITE Smart IDE: Visual Editors

10. SiriusCon21 17.06.2021
SODALITE Smart IDE: In-Sync Multiview
representations
Textual (XText):
High productivity
Graphical (Sirius)
High communication
Tree (XText, read-only)

11. • Modeling visual granularity
• Modeling element layout
• Inline vs form-based edition
SODALITE Smart IDE: Modeling challenges

12. SODALITE Smart IDE: Known issues
• Positional (Indentation-based or Whitespace-Aware Languages)
formatting for textual notation - YAML notation
• Changes in indentation causes errors in model parsing
• XText formatting implemented and triggered.
• XText - Sirius model
synchronization
• Altran XText integration
with Sirius: Xtext Inline
Editors

13. • Addressing know issues
• Inline edition of AADM elements
• Web based editor for AADM - Sirius Web
• PoC requested by EC reviewers
• Visual editor for other SODALITE DSMLs
• Resource pending, maybe in SODALITE-2
• Multiple viewpoint representations of the same AADM with Sirius
views
• Resource pending, maybe in SODALITE-2
