OPICScoringFilter & Metadata transport scores as String
OPICScoringFilter line 91:
content.getMetadata().set(Fetcher.SCORE_KEY, "" + datum.getScore());
and line 96,102 we set and get the Fetch Sore as Strings. :-o.
Wouldn't it be better to have the Metadata support floats as well
instead of serializing and parsing strings?
In general wouldn't it be a good idea to have Metadata as child of
MapWritable ? OO Design?
