Invenio-DNB-Urn

DNB support module for InvenioRDM. It offers a URN PIDProvider and additional metadata formats to be included in the OAI-PMH server. Currently these are epicur and xMetaDissPlus. In a later step the epicur format will be replaced by extending the URN PIDProvider by accessing the DNB REST-APIs to directly mint new and changed URN's.

Configuration

Add the following to invenio.cfg:

In order to fully implement xMetaDissPlus with all mandatory fields, the metadata definition has to be expanded by custom fields. At first add the file thesis_types.yaml to /app_data/vocabularies, then add

thesis:
  pid-type: ths
  data-file: vocabularies/thesis_types.yaml

to the vocabularies.yaml. Next, add

from invenio_records_resources.services.custom_fields import TextCF
from invenio_vocabularies.services.custom_fields import VocabularyCF

RDM_NAMESPACES = {
  # DNB Thesis
  "thesis": "https://dnb.de/thesis/",
}

RDM_CUSTOM_FIELDS = {
  VocabularyCF(
    name="thesis:level",
    vocabulary_id="thesis",
    dump_options=True,
    multiple=False,
  ),
  TextCF(
    name="thesis:organisation",
  ),
  TextCF(
    name="thesis:place",
  ),
}

RDM_CUSTOM_FIELDS_UI = [
  {
    "section": _("Hochschulschriftenvermerk"),
    "fields": [
      dict(
        field="thesis:level",
        ui_widget="Dropdown",
        props=dict(
          label="Abschluss",
          placeholder="Grad des Abschlusses",
          icon="pencil",
          description="You should fill this field with the thesis degree",
          search=True,  # True for autocomplete dropdowns with search functionality
          multiple=False,   # True for selecting multiple values
          clearable=True,
          required=False,
        )
      ),
      dict(

to your invenio.cfg and execute

pipenv run invenio rdm-records custom-fields init
