CCMM-Invenio: CCMM runtime library for NRP Invenio

This library provides:

an OARepo model preset for CCMM datasets (ccmm_preset_1_1_0)
CCMM XML import and export (REST, OAI-PMH)
vocabulary fixtures for the CCMM model
UI components for working with the CCMM model in NRP Invenio

Installation

pip install ccmm-invenio

Usage

To use CCMM in a repository, add the following model:

# models/datasets.py
from ccmm_invenio.models import ccmm_preset_1_1_0

ccmm_dataset = model(
    "ccmm_dataset",
    version="1.1.0",
    presets=[
        ccmm_preset_1_1_0,
    ],
    configuration={
        # "ui_blueprint": "myui
    },
    types=[
        {
            "Metadata": {
                "properties": {
                    # your extensions come here, ccmm_preset_1_1_0 will add
                    # all ccmm fields automatically
                },
            },
        }
    ],
    metadata_type="Metadata",
    customizations=[],
)

# invenio.cfg
ccmm_dataset.register()

ccmm_production_preset_1_1_0 is an alias of ccmm_preset_1_1_0.

The preset adds the CCMM XML import and export (application/vnd.ccmm+xml, also OAI-PMH with the ccmm metadata prefix). See AGENTS.md for the design of the model and of the CCMM conversion.

How to adapt to a new CCMM version

Download and pre-process CCMM XML

Follow the instructions in ccmm_versions/README.md to download and pre-process the CCMM XML schemas for the desired version. This will create:

Cleaned XSD files in ccmm_versions/src/ccmm_versions/ccmm-<version>-<date>/out
A diff file in ccmm_versions/diffs/ comparing the new version to the previous one
A schema overview in ccmm_versions/summaries/ccmm-<version>-<date>.summary.md

Adapt the model yaml files

Copy the model in src/ccmm_invenio/models/<previous-version>-<date>/ to src/ccmm_invenio/models/<new-version>-<date>/.

Look at the diff file generated in the previous step and adapt the ccmm.yaml (the CCMM types used by the model), ccmm-invenio.yaml (the dataset, RDM based) and ccmm-vocabularies.yaml files in src/ccmm_invenio/models/<version>-<date>/ accordingly.

Then add the new version to src/ccmm_invenio/models/__init__.py, the new XSD to src/ccmm_invenio/resources/serializers/ccmm/xsd/ (updating the path in converter.py) and adapt the marshmallow schemas in src/ccmm_invenio/resources/serializers/ccmm/schema/.
