Hi everyone, as i will bring the open mastr datapackage to the NFDI metadata workshop i updated the current OEMetadata (datapackage.json) from this release https://zenodo.org/records/14783581 to OEMetadata version 2 using omi.

This is one possibility how one could do that using the latest version of omi:

from omi.conversion import convert_metadata

from pathlib import Path
from json import load, dumps

from omi.validation import validate_metadata

def read_json(path: Path, file: str):
    """Load Metadata File"""
    with open(path / file, "r", encoding="utf-8") as metadata:
        data = load(metadata)
    return data


def write_json(path: Path, file: str, data: dict):
    """Write new Metadata File"""
    with open(path / file, "w", encoding="utf-8") as metadata:
        data = dumps(
            data,
            indent=4,
        )
        metadata.write(data)


if __name__ == "__main__":

    path = Path.cwd() / "local_test/data"
    file = "bnetza_open_mastr_datapackage.json"
    metadata = read_json(path=path, file=file)

    # use omi to convert it to the latest release
    converted = convert_metadata(metadata, "OEMetadata-2.0")
    # validate_metadata(converted)

    result_path = Path(Path.cwd(), "local_test/result")
    result_file = "bnetza_open_mastr_datapackage_md_v2_conversion.json"
    write_json(result_path, result_file, converted)

And the result ... as we extended the linked data capabilities, the '@ id' field is used frequently. The conversion will add null values to blank '@ id' properties. This is not good to keep, as linked data parsers will complain. Be careful when you want to publish a converted document. There is code that removes the empty values, but it not yet available as cleanup functionality in omi.

v2 Introduces the dataset "overview" section ontop of the json document, which is empty by default. I added some entries.
