Rupert Westenthaler reopened STANBOL-1417:
------------------------------------------
Looks like the EnhancementEngineHelper#getLanguageAnnotations(...) has problems
with Float values as written by the implementation of this issue.

java.lang.Double from a literal of type

> Create Language Annotation for parsed "Content-Language" header
> ---------------------------------------------------------------
>
> Key: STANBOL-1417
> URL: https://issues.apache.org/jira/browse/STANBOL-1417
> Project: Stanbol
> Issue Type: Improvement
> Components: Enhancement Engines
> Affects Versions: 0.12.0
> Reporter: Rupert Westenthaler
> Assignee: Rupert Westenthaler
> Priority: Minor
> Fix For: 1.0.0, 0.12.1
>
>
> Stanbol supports parsing the language of the content by using the
> "Content-Language" header since STANBOL-660. However currently only the
> `dc:language` property is set for the ContentItem.
> However based on the specification of STANBOL-613 this information is only
> used as fallback if no language annotation is present in the ContentItem. So
> as soon as any Language Identification Engine is present in the Chain the
> "Content-Language" as parsed by the User will get ignored. This is not the
> intention of a user explicitly parsing the language.
> To force Stanbol to use the parsed language a Language Annotation with the
> confidence 1.0 needs to be added to the metadata of the ContentItem instead.
