Known Issues

Kotar is under active development. The following limitations are known in the current release.

Area	Known Issue / Limitation
Model Identity / UUIDs	Persistent UUIDs cannot always be preserved across arbitrary text-only edits. Identity preservation is best-effort when models are modified outside kernel-integrated tooling.
Graphical / Textual Editing	Bidirectional projective editing is supported, but some textual restructuring may make it difficult to preserve graphical element identity or layout.
Unnamed Elements	Unnamed model elements can create ambiguity when correlating elements between textual and graphical representations.
Model Diff	Model-aware diff is currently limited. More advanced semantic model comparison is under development.
SPARQL Queries	Direct SPARQL queries operate on the minified RDF representation. Derived SysML v2 properties may therefore not appear directly in query results.
SysML v2 RDF View	A fully materialized/derived SysML v2 view for SPARQL queries is planned but not yet implemented.
SysML Views as Diagrams	SysML v2 View and Viewpoint elements cannot yet directly drive graphical views.
External Tool Synchronization	Live synchronization of model changes made by external engineering tools is still under development.
Automatic Source Detection	User control for enabling/disabling automatic source-change detection may not yet be available in all releases.
Repository Launch Configuration	Launching Kotar with a Git repository/project automatically preconfigured is not yet fully packaged.
Browser Local-Service Access	Browser security restrictions can limit direct access to arbitrary services running on the local machine and may require additional configuration.
