Sebastian Nagel commented on NUTCH-3101:
----------------------------------------

Hi [~markus17],

changing the format of the LinkDb is a breaking change. Existing LinkDbs become 
unreadable. Given this substantial change, could you outline how the metadata 
shall be populated?

The patch applies to master and compiles. I was able to write a LinkDb with 
metadata included (but empty).

The patch also includes changes to (Javadoc) comments and override annotations 
- Are this changes intentional?
- the license header is now a Javadoc comment
- Javadoc comments are converted to ordinary comments
- {{@param}} and {{@throws}} Javadoc annotations are removed which makes {{ant 
javadoc}} fail
- all {{@Override}} annotations are lost
