[META] OSRD - NGE (NetzGrafik-Editor) #7534

Open louisgreiner opened 1 month ago

louisgreiner commented 1 month ago

Description

NetzGrafik-Editor (NGE) is an open-source software that enables the creation, modification, and analysis of regular-interval timetable, at a macroscopic level of details, developped by SBB.

This feature is about integrating NGE in OSRD application, synchronizing both workspaces, allowing timetable edition at both microscopic and macroscopic level of details at the same time.

A Proof of Concept has been developped, see dedicated repository.

The PoC functionnalities are:

The following chart describes the workflow from the PoC:

---

flowchart TD
    OSRD_data_source[OSRD as data source] -- import infra & timetable --> NGE;
    Viriato_data_source[Viriato as data source] -- import infra & train groups --> NGE
    subgraph synchronous_workspace[" "]
        NGE -- create, modify or delete trainruns --> NGE
        NGE -- export trainruns --> OSRD
        OSRD -- (re)calculate pathfindings and running times \n& create, modify or delete train schedules --> OSRD
        OSRD -- update model --> NGE
    end

The PoC works by running OSRD and NGE as separate services and not automated synchronization.

This would also show that open-source cooperation is powerful and a huge gain of time in software development. See front-end and back-end repositories for contributions.

Once the Netzgrafik-Editor is integrated into OSRD we shall check whether we have to change some Netzgrafik-Editor data structure to ensure that all component works as they are required for taktfahrtplan, especially editing, streckengrafik, ...
