Create RDF data from Excel spreadsheets - edit SKOS vocabularies, knowledge graph instances, SHACL constraints, OWL ontologies in Excel files. Available as HTTP service, upload form, command-line, or Java API.
Currently only http(s) URLs are allowed as ConceptScheme URI values.
In fact, URIs can have other schemas. Moreover, a URN is a valid subtype of a URI.
For example, specifying the following valid URIs as ConceptScheme values results in empty SKOS output for otherwise valid spreadsheets:
ftp://example.com/rdf.
tag:example.com,2000:/rdf
Note: I only tried the online version of the SKOS Play!
