This project adds a graphical user interface(GUI) for exporting data of OpenRefine projects in RDF format. The export is based on mapping the data to a template graph using the GUI. It also provides a service for reconciling data against SPARQL endpoints (e.g., DBpedia).
You need to have Java and OpenRefine installed on your machine.
- Java 11
- OpenRefine 3.6
- If it does not exist, create a folder named extensions/rdf-extension under your user workspace directory for OpenRefine. The workspace should be located in the following places depending on your operating system (see OpenRefine FAQ for more details):
- Linux ~/.local/share/OpenRefine
- Windows C:/Documents and Settings//Application Data/OpenRefine OR C:/Documents and Settings//Local Settings/Application Data/OpenRefine
- Mac OSX ~/Library/Application Support/OpenRefine
- Unzip the downloaded release (ensuring it is a rdf-extension-x.x.x-*.zip not a source code .zip or tar.gz) into the extensions/rdf-extension folder (step 1). It is recommended that you have an active internet connection during the first run of the extension, as it will try to download a set of predefined vocabularies (rdf, rdfs, owl and foaf). You can add them later also.
- Restart OpenRefine (OpenRefine usage instructions are provided in the user documentation)
- Clone this extension repository to your local machine
- Checkout the main branch
git checkout main - Run
mvn clean compileandmvn assembly:single - Unpack the zip file created in the
targetdirectory to a sub-directory of the extensions folder of OpenRefine e.g.,extensions/rdf-extension
If you have previously installed the extension you will need to replace it in the OpenRefine extensions directory with the newly built version.
