Please explain a little more what you are trying to do. If you are
trying to set meta-data in crawldatum you can call:
crawldatum.getMetaData().put(key, value)

Hi,
I'm trying to store a new meta data field in my implementation of
ScoringFilter, using Nutch 0.9. The meta data is only available after
parsing, but passScoreAfterParsing doesn't offer write access to the meta
data (i.e. you can call set methods but the values will not be written).
So I'm trying to use distributeScoreToOutlink(). I thought returning
an "adjust" value like this should work, but none of the meta fields I add
every appear in Selector.map() in Generator.java (I patched Generator.java
to display the meta data for debugging purposes):
adjust = new CrawlDatum();
adjust.setStatus(CrawlDatum.STATUS_LINKED);
MapWritable myMetaData = new MapWritable();
myMetaData.put(new Text("foo"), new FloatWritable(9.9f));
adjust.setMetaData(myMetaData);
What am I doing wrong? Note that setting meta data on the outlink pages in
distributeScoreToOutlink works fine, but I want to set values for the
original page.
Regards
Daniel
