ebdtable2graph 0.1.20

Converts (already scraped) Entscheidungsbaumdiagramm tables to real graphs

ebdtable2graph

🇩🇪 Dieses Repository enthält ein Python-Paket namens ebdtable2graph, das genutzt werden kann, um aus .docx-Dateien extrahierte maschinenlesbare Tabellen, die einen Entscheidungsbaum (EBD) modellieren, in echte Graphen zu konvertieren. Diese Entscheidungsbäume sind Teil eines regulatorischen Regelwerks für die deutsche Energiewirtschaft und kommen in der Eingangsprüfung der Marktkommunikation zum Einsatz.

🇬🇧 This repository contains the source code of the Python package ebdtable2graph.

Rationale

Assume, that you scraped the Entscheidungsbaumdiagramm tables by EDI@Energy from their somewhat "digitized" PDF/DOCX files. (To do so, you can use the package ebddocx2table.) Also assume, that the result of your scraping is a ebdtable2graph.models.EbdTable.

The package ebdtable2graph contains logic to convert your scraped data into a graph. This graph can then be exported e.g. as SVG and/or UML.

How to use ebdtable2graph?

Install the package from pypi:

pip install ebdtable2graph

Create an Instance of EbdTable

EbdTable contains the raw data by BDEW in a machine-readable format. Creating instances of EbdTable is out of scope for this package. Ask Hochfrequenz for support on this topic. In the following example we hard code the information.

from ebdtable2graph.graph_conversion import convert_table_to_graph
from ebdtable2graph.models import EbdCheckResult, EbdTable, EbdTableMetaData, EbdTableRow, EbdTableSubRow, EbdGraph

ebd_table: EbdTable  # this is the result of scraping the docx file
ebd_table = EbdTable(  # this data shouldn't be handwritten
    metadata=EbdTableMetaData(
        ebd_code="E_0003",
        chapter="7.39 AD: Bestellung der Aggregationsebene der Bilanzkreissummenzeitreihe auf Ebene der Regelzone",
        sub_chapter="7.39.1 E_0003_Bestellung der Aggregationsebene RZ prüfen",
        role="ÜNB",
    ),
    rows=[
        EbdTableRow(
            step_number="1",
            description="Erfolgt der Eingang der Bestellung fristgerecht?",
            sub_rows=[
                EbdTableSubRow(
                    check_result=EbdCheckResult(result=False, subsequent_step_number=None),
                    result_code="A01",
                    note="Fristüberschreitung",
                ),
                EbdTableSubRow(
                    check_result=EbdCheckResult(result=True, subsequent_step_number="2"),
                    result_code=None,
                    note=None,
                ),
            ],
        ),
        EbdTableRow(
            step_number="2",
            description="Erfolgt die Bestellung zum Monatsersten 00:00 Uhr?",
            sub_rows=[
                EbdTableSubRow(
                    check_result=EbdCheckResult(result=False, subsequent_step_number=None),
                    result_code="A02",
                    note="Gewählter Zeitpunkt nicht zulässig",
                ),
                EbdTableSubRow(
                    check_result=EbdCheckResult(result=True, subsequent_step_number="Ende"),
                    result_code=None,
                    note=None,
                ),
            ],
        ),
    ],
)
assert isinstance(ebd_table, EbdTable)

ebd_graph = convert_table_to_graph(ebd_table)
assert isinstance(ebd_graph, EbdGraph)

Export as PlantUML

from ebdtable2graph import convert_graph_to_plantuml

plantuml_code = convert_graph_to_plantuml(ebd_graph)
with open("e_0003.puml", "w+", encoding="utf-8") as uml_file:
    uml_file.write(plantuml_code)

The file e_0003.puml now looks like this:

@startuml
...
if (<b>1: </b> Erfolgt der Eingang der Bestellung fristgerecht?) then (ja)
else (nein)
    :A01;
    note left
        Fristüberschreitung
    endnote
    kill;
endif
if (<b>2: </b> Erfolgt die Bestellung zum Monatsersten 00:00 Uhr?) then (ja)
    end
else (nein)
    :A02;
    note left
        Gewählter Zeitpunkt nicht zulässig
    endnote
    kill;
endif
@enduml

Export as SVG

You can also export the graph as SVG

from ebdtable2graph import convert_plantuml_to_svg_kroki

svg_code = convert_plantuml_to_svg_kroki(plantuml_code)
with open("e_0003.svg", "w+", encoding="utf-8") as svg_file:
    svg_file.write(svg_code)
