FedORKG

ckanext-fedorkg is a CKAN plugin that adds support to query open research knowledge graphs via SPARQL queries. FedORKG uses DeTrusty as federated query engine. The visual query editor connecting the frontend and DeTrusty is implemented using the JavaScript library YASGUI.

[!NOTE] This feature is experimental.

Powered by the LLM o1-mini, FedORKG is able to answer natural language questions over the federation by relying on the LLM to translate the question into a SPARQL query. Check steps 3 and 4 in the post-install setup on how to configure this feature.

Installation

Path variables used below:

• $CKAN_STORAGE_PATH (i.e., where CKAN stores files), e.g., /var/lib/ckan
• $CKAN_INI (i.e., the CKAN configuration file), e.g., /etc/ckan/default/ckan.ini

git clone git@github.com:SDM-TIB/ckanext-fedorkg.git
pip install -e ./ckanext-fedorkg
pip install -r ./ckanext-fedorkg/requirements.txt

Post-install Setup
