This repository contains the MaRDMO Plugin for the Research Datamanagement Organizer (RDMO) developed within the Mathematical Research Data Initiative (MaRDI).
The plugin allows a standardized documentation of:
- Mathematical Models
- Interdisciplinary Workflows
- Algorithms
Model documentation in MaRDMO is based on the MathModDB ontology. Within the plugin, users can record a model, related expressions, computational tasks, quantities or quantity kinds, research problems, academic disciplines, and publications. These inputs are gathered in a guided interview, enabling MaRDMO to produce metadata that is directly compatible with the MaRDI knowledge graph for mathematical models. A demo video showing the documentation process for a mathematical model in MaRDMO is available here.
Workflow documentation follows a standardized scheme developed in MaRDI. Within the plugin, users can record a workflow, related models, methods, software, hardware, experimentall devices, data sets, and publications. These inputs are gathered in a guided interview, enabling MaRDMO to produce metadata that is directly compatible with the MaRDI knowledge graph for interdisciplinary workflows.
Algorithm documentation in MaRDMO follows the MathAlgoDB ontology. Within the plugin, users can record an algorithm, related algorithmic tasks, implementing software, benchmarks, and publications. These inputs are gathered in a guided interview, enabling MaRDMO to produce metadata that is directly compatible with the MaRDI knowledge graph for algorithms.
Figure 1: MaRDMO Data Model containing Classes and Relations for the Documentation of Mathematical Models (blue), Algorithms (red), and Interdisciplinary Workflows (green).
Completed documentations in MaRDMO can be exported directly from RDMO to the respective MaRDI knowledge graph via the MaRDMO Button. This feature generates a concise summary of the documented model, algorithm, or workflow, and—after user authentication—submits the metadata to the corresponding knowledge graphs. This streamlines the publication process and ensures the documentation becomes immediately discoverable within the MaRDI ecosystem.
In addition to documentation, MaRDMO provides a dedicated interview for searching existing workflows, algorithms, and models. Users can specify individual search parameters, and the MaRDI Button will generate the corresponding SPARQL query based on the input. The query results are displayed directly in RDMO, enabling researchers to discover and reuse existing knowledge—thus closing the knowledge transfer loop within the MaRDI ecosystem.
To use the MaRDMO Plugin at least RDMO v2.3.0 is required. Follow the installation / update instructions of RDMO if required.
Go to the rdmo-app directory of your RDMO installation. In the virtual environment of the RDMO installation install the MaRDMO Plugin:
pip install MaRDMOTo connect the MaRDMO Plugin with the RDMO installation add the following lines to config/settings/local.py (if not already present):

In addition add the following urlpattern to config/urls.py:
path('services/', include("MaRDMO.urls")),Thereby, the MaRDMO Plugin is installed and a "MaRDI Button" button is added in the project view.
Add the following lines to config/settings/local.py to connect MaRDMO with the individual databases.

The MaRDMO Plugin requires the MaRDMO-Questionnaire, download its latest release 
Integrate the MaRDMO Questionnaire into your RDMO instance through the user interface of your RDMO instance (Management -> Import -> attributes.xml/optionsets.xml/conditions.xml/catalogs.xml) or via
python manage.py import /path/to/MaRDMO-Questionnaire/catalog/attributes.xml
python manage.py import /path/to/MaRDMO-Questionnaire/catalog/optionsets.xml
python manage.py import /path/to/MaRDMO-Questionnaire/catalog/conditions.xml
python manage.py import /path/to/MaRDMO-Questionnaire/catalog/mardmo-search-catalog.xml
python manage.py import /path/to/MaRDMO-Questionnaire/catalog/mardmo-model-catalog.xml
python manage.py import /path/to/MaRDMO-Questionnaire/catalog/mardmo-interdisciplinary-workflow-catalog.xml
python manage.py import /path/to/MaRDMO-Questionnaire/catalog/mardmo-algorithm-catalog.xmlOnce the MaRDMO Plugin is set up, the Questionnaires can be used to document and query interdisciplinary workflows, mathematical models, and algorithms. Therefore, select "Create New Project" in RDMO, choose a proper project name (for interdisciplinary workflow the project name will the workflow name), assign one of the the MaRDMO Catalogs and select "Create Project". The project is created. On the right hand side in the "Export" category the "MaRDMO Button" button is located to process the completed Questionnaires. Choose "Answer Questions" to start the interview.
