Format

We use JSON to represent the graphs. Such a file consists of an node array and an edge array.

{
    "nodes": [
        {
            "id": "MiKoMH/AI/source/prolog/en/logic-programming-intro.tex",
            "color": "#0000ff",
            "label": "logic-programming-intro"
        },
        {
            "id": "MiKoMH/AI/source/prolog/en/facts-rules.tex",
            "color": "#0000ff",
            "label": "facts-rules"
        }
     ],
     "edges": [
        {
            "id": "MiKoMH/AI/source/prolog/en/facts-rules.tex??MiKoMH/AI/source/prolog/en/logic-programming-intro.tex",
            "style": "include",
            "to": "MiKoMH/AI/source/prolog/en/facts-rules.tex",
            "from": "MiKoMH/AI/source/prolog/en/logic-programming-intro.tex",
        }
     ]
}

It is easy to add new fields to the JSON in the future but for now, we use the following:

• node: id for identification, color of the 3D node object and a text label
• edge: id for identificaiton, target and origin node id and a style, which is later mapped to a certain layout attribute.
