Markus Jelsma commented on NUTCH-2865:
--------------------------------------
* separated the parseText and parseData
* changed the response flag
* contentMeta and parseMeta are now added as valid JSON using GSON
* Refers-To field added
It 's all not very beautiful code, and some partial duplicate pieces, but it
works.
> WARC exporter support for metadata and dropping empty responses

> WARCExporter is a handy tool to dump the segments. Unfortunately it also
> emits WARC records for status' other than success of notmodified, which
> accounts for a decent number in each crawl cycle. It also doesn't emit parsed
> metadata or extracted text. It does now.
>
> This patch adds three switches:
> * -includeOnlySuccessfulResponses to only emit records of success or
> notmodified
> * -includeParseData to also emit parse metadata as WARC metadata record
> * -includeParseText to also emit extracted text as WARC metadata
> Both metadata objects are stored in the same WARC metadata record to save
> space.
