Subject [jira] [Commented] (NUTCH-1467) nutch 1.5.1 not able to parse mutliValued metatags
Date Sun, 03 Mar 2013 15:53:12 GMT


Sebastian Nagel commented on NUTCH-1467:

Hi Kiran, my suggestion was only about the data structure as such: the class {{metadata.Metadata}}
is exactly what we need - a container to store maps key -> multiple values. What about
just changing the type of {{HTMLMetaTags.generalTags}} to {{Metadata}}? It would save some
lines of code in HTMLMetaProcessor because Metadata provides handy methods to add values.

It does not work quite well when there are two metatags with same name but two different contents.

> Does anyone encounter this kind of issue ?  
> Are there any changes that need to be made to the config files to make it work ?
> When there are two tags with same name and different content, it takes the value of the
later tag and saves it rather than creating a multiValue field.

> Many Thanks,
