SSSOM is a way to specify semantic mappings, typically based on SKOS.
SSSOM mapping ar typically edited collaboratively as tab-separated text files, which can then be converted to OWL assertions using the SSSOM toolkit.
Please edit prov-mapping.tsv taking care not to break the tabular characters. You may use the Rainbow CSV extension in Visual Studio Code, or a spreadsheet software.
The metadata headers are maintained in prov-mapping.yml as well as in ro-crate-metadata.json.
Install the SSSOM toolkit.
If you use Conda, you can use:
conda env create -f environment.yml
conda activate sssom
Then to generate the converted file formats prov-mapping.rdf prov-mapping.json prov-mapping.ttl
run:
make
