This program is a specialized validator for the Open Publication Distribution System (http://http://opds-spec.org/). It's based on Jing (http://code.google.com/p/jing-trang/).
The validator depends on jing and relaxng-datatype jars which at the moment should be located :
/usr/share/jing/lib/jing.jar
/usr/share/relaxng-datatype/lib/relaxngDatatype.jar
Compilation should be as easy as
$ ant
usage: java -jar OPDSValidator [options] file
Options:
-h This help message
-v opds_version OPDSVersion to use (default 1.0)
-e encoding File encoding (passed to jing)
-f format Error output format (default text, avail : json)
