Replace fake URIs with the actual URIs in metadata.yml
Update version of sssom-py so that can use multiple prefixes with the same URI (refer to https://github.com/mapping-commons/sssom-py/issues/408), then can use the Bioregistry to look up the correct URIs for the src/ontology/config/metadata.yml
file. Once fixed, re-build obsolete.sssom.tsv
.
