svn commit: r1293251 - in /incubator/stanbol/trunk/enhancer:
generic/servicesapi/src/main/java/org/apache/stanbol/enhancer/servicesapi/rdf/NamespaceEnum.java
ldpath/src/main/java/org/apache/stanbol/enhancer/ldpath/EnhancerLDPath.java
Author: rwesten
Date: Fri Feb 24 13:53:28 2012
New Revision: 1293251
URL: http://svn.apache.org/viewvc?rev=1293251&view=rev
Log:
STANBOL-500: forgot to commit the EnhancerLDPath class; Added a "fise:" namespace prefix as alternative to "enhancer". The intension is that the "fise" prefix will always point to the currently used enhancement structure and the "enhancer" namespace will be changed as soon as we switch to the new one.
Added:
incubator/stanbol/trunk/enhancer/ldpath/src/main/java/org/apache/stanbol/enhancer/ldpath/EnhancerLDPath.java (with props)
