Library of small Java functions, semantically described with the FNO ontology. This enables the use e.g. in RML mappings. The functions included deal with the following topics

• prefix substitution
• copies of some grel functions, adapted with null input handling
• timestamp conversion

• The RMLMapper and YARRRML supports usage of functions via FNO. You can add the functions on invocations of the rmlmapper-java by using the -f parameter of rmlmapper and adding the function library to the java classpath.
• For usage with Function-Agent-Java see tests.
• xlsx2owl uses SeMiFuLi.

• v0.2.1 (9.11.2023)
  • added readme, some cleanup
  • added String functions contains and notContains
  • major cleanup on functions_xlsx2owl.ttl, moved grel parameter definition copies to grelTypes.ttl, updated jar path, reordered entries
