Data preparation today
Every Infrastructure Manager has a long tradition of presenting signalling information in given shapes and formats, inherited from the days of paper and steam.
France:
Norway:
United Kingdom:
Netherlands:
Germany:
The signalling supply industry ingests and interprets this information, and processes it. Ingestion and interpretation of data are the weak links in the chain.
Data preparation tomorrow
Seamless machine-to-machine flow of information between IM and signalling suppliers.
This is the key EULYNX DP use case – but it can do a lot more.
Example of a typical EULYNX DP diagram
The diagrams are designed for
- Accessibility and focus
- Presentation in HTML format
- Subject-matter diagrams collect all information
- Users browse for information at their ease
- UML classification and relations
- Semantics: what does it mean
- Associated attributes
- Generalisation – Specialisation: helps keeping it as simple as possible but not any simpler
- Relations: Class A needs/owns/knows class B, e.g. How does a signal relate to a route
- Examples
- The semantics are supported by graphc examples
- Examples support the communication between signalling and IT experts.
EULYNX DP versus conventional information models
The EULYNX DP model represents signalling know-how. The graphics support understanding that is accessible to both IT- and signalling professionals.
A conventional XSD model is tied to XML, has little to no visual support. XSD’s are familiar to IT professionals but difficult to grasp for signalling professionals
