Nick commented on NUTCH-1478:
-----------------------------
This plugin works great if the page has the metatags mentioned in the
index.content.md but breaks if they are missing. How do I go about making the
fields optional?

> Parse-metatags and index-metadata plugin for Nutch 2.x series
> --------------------------------------------------------------
>
> Key: NUTCH-1478
> URL: https://issues.apache.org/jira/browse/NUTCH-1478
> Project: Nutch
> Issue Type: Improvement
> Components: parser
> Affects Versions: 2.1
> Reporter: kiran
> Fix For: 2.3
>
> Attachments: metadata_parseChecker_sites.png, Nutch1478.patch,
> Nutch1478.zip
>
>
> I have ported parse-metatags and index-metadata plugin to Nutch 2.x series.
> This will take multiple values of same tag and index in Solr as i patched
> before (https://issues.apache.org/jira/browse/NUTCH-1467).
> The usage is same as described here
> (http://wiki.apache.org/nutch/IndexMetatags) but one change is that there is
> no need to give 'metatag' keyword before metatag names. For example my
> configuration looks like this
> (https://github.com/salvager/NutchDev/blob/master/runtime/local/conf/nutch-site.xml)
>
> This is only the first version and does not include the junit test. I will
> update the new version soon.
> This will parse the tags and index the tags in Solr. Make sure you create the
> fields in 'index.parse.md' in nutch-site.xml in schema.xml in Solr.
> Please let me know if you have any suggestions
> This is supported by DLA (Digital Library and Archives) of Virginia Tech.
