This repository is the supplement data for the dissertation "Charting the Railway Infrastructure Design Process - with a layer model from topology to transport". The main result is the schema/layer_model.json file with the dissertation result in the JSON schema format. The result was achieved by following the Design Science Research method, which consists of cycles. The cycles are documented in the DSR_cycles folder and the git commits of this repository. At the same time, the final result of the DSR cycles is an artefact in the / respectively folders data/layers, schema, src, and test. Julia and YAML were used for data transformation and data input.
-
data/raw: Input data for the DSR cycles - a fictitious network used by teaching at the Institute of Railway Systems Engineering and Traffic Safety at Technical University Braunschweig. -
data/layers: Converted raw input data into YAML files according toschema/layer_model.json. -
data/snippets: Selected YAML snippets to test the modelling of the object referred to in the snippet name. -
DSR_cycles: Documented progress in each of the eight DSR cycles. Please also refer to the commits of the git repository. -
schema: The final JSON schema file to validate the YAML files in the data/layers and the data/snippets folder. This can be done, for example, with Ajv JSON schema validator with the following command for the base layer:
ajv --spec=draft2020 -c ajv-formats -s schema/layer_model.json -d data/layers/base.yaml-
src,test: Julia code for data transformation, plausibility, and validation tests while constructing the DSR artefact. -
TODO.md: A collection of thoughts where the Railway Layer Model still needs improvement. -
insights.md: A collection of thoughts during each DSR cycle for each layer.
