Edge manager cannot handle delimiters longer than one character

[marc-hanheide]

Bug Description

The Edge manager in topological navigation currently cannot handle delimiters (column delimiters) that are longer than one single character. This affects edge names and mode names.

Impact

• Blocks testing at Driscoll's and any longer tunnel environment
• Affects edge names and mode names that use multi-character delimiters
• Prevents use of more descriptive naming schemes

Immediate Fix Required

Fix to handle multi-character delimiters for:

• Edge names
• Node names

URGENT: Needed for Rise Home testing

Mid-term Enhancement

Change topological navigation to not rely on specific naming schemes. Instead, use semantic annotations of edges and nodes as designed in the property system. see #215

Priority

URGENT - Blocking larger scale deployments

Context
