Hey,
May the freshly added CrawlDatum.setMetaData can help you to store
such informations.
However you need somehow to hack nutch code, since this is not stored
until today yet there is no extension point for such a task.

I have worked through the
WritingPluginExample<http://wiki.apache.org/nutch/
WritingPluginExample>example.
Now I am wondering if the following makes any sense. I would like
to store the date (yyyymmdd) the first time a Page was added to the
Index. I
thought I could create a plugin that would add a date_indexed
field. My
hesitation is what happens after the fetch interval, when the Page is
refetched.
What happens
- if the Page Content has changed? Is the Page updated (i.e.
deleted and
added) in the index and would the date_indexed be recalculated
(would be
ok.)
- if the Page hasn't changed? Is the Page also updated (would break
the
meaning of the date_indexed field, not ok).
Or does this depend on how I organize my generate/fetch/update/
index cycle,
i.e. if I merge my indexes or recreate them from scratch?
Rgrds, Thomas
