>          Issue Type: Improvement
>          Components: metadata
>    Affects Versions: 1.13

>         Attachments: metadataARG_SEGMENT.patch
> The class metadata/  public static final String ARG_SEGMENT = "segment" is
not used correctly. In some cases Fetcher and ParseSegment it is interpreted as a single segmenet,
in others CrawlDb, LinkDb, IndexingJob as an array of segments. Such misunderstanding leads
to inconsistency of usage of the parameter.
> After a discussion with [~wastl-nagel]  the proposed solution is to allow the usage of
both array and a string in all cases. That gives an opportunity to not introduce the broken
> A path is proposed.
>  *The question left is refactoring, all these five components share the same code(two
versions of the same code to be precise). Shouldn't we extract a method and reduce duplicates?
