RDF4J Schema Generator provides a command line tool and maven plugin that allows to create constants for RDF primitives for a given namespace from RDF ontology files.
How To
- Clone from https://github.com/ansell/rdf4j-schema-generator.git

./rdf4j-schema-generator <input-file> <output-file> - Additional information can be configured using command-line parameters
Command Line Options
<input-file> the input file to read from
[<output-file>] the output file to write, StdOut if
omitted
-b,--languageBundles generate L10N LanguageBundles
-c,--constantCase <constantCase> case to use for URI constants,
possible values: LOWER_UNDERSCORE,
LOWER_CAMEL, UPPER_CAMEL,
UPPER_UNDERSCORE
-C,--stringConstantCase <constantCase> case to use for String constants, see
constantCase
-f,--format <input-format> mime-type of the input file (will try
to guess if absent)
-h,--help print this help
-l,--language <prefLang> preferred language for schema
labels
-n,--name <ns> the name of the namespace (will try to

-P,--stringConstantPrefix <prefix> prefix to create string constants
