SeMiFuLi: Semantically described mini function library

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

Usage

• 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.
