Turtle Prefixes with Hyphens Require Escaping to Compile as Java Package Names #16

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.  Create some RDF data in Turtle format that uses a hyphenated prefix name 
(e.g. dbpedia-owl:) and uses that prefix in a Class assignment (e.g. "<MyClass> 
a dbpedia-owl:Company .")
2.  Place the Turtle file in the webapps directory of a Callimachus instance.
3.  Callimachus will fail to start with an error like this:

Because Java cannot compile package names with hyphens in them, hyphens must be 
changed (e.g. to underscores) before compilation is attempted.
