com.complexible.common.rdf.rio.RDFObfuscator

All Implemented Interfaces:

Function<Statement,Statement>

public final class RDFObfuscator
extends Object
implements Function<Statement,Statement>

This is a simple utility program to obfuscate the contents of an RDF file. The program will obfuscate all IRIs and string literals using a message digest algorithm. Bnodes and non-string typed literals are left unchanged. The obfuscation is guided by a configuration file. Configuration can specify which IRIs and string will be obfuscated by defining inclusion and exclusion filters.
