> Key: COCOON3-77
> URL: https://issues.apache.org/jira/browse/COCOON3-77
> Project: Cocoon 3
> Issue Type: Improvement
> Components: cocoon-optional
> Affects Versions: 3.0.0-alpha-3
> Reporter: Andre Juffer
> Priority: Minor
> Attachments: EncodingJsonSerializer.java,
> EncodingTextSerializer.java, JsonSerializer.java, TextEncoder.java,
> TextSerializer.java, pom.xml, tribc-cocoon-3.xml
>
>
> Serveral classes have been created for serializing text and JSON in the
> sitemap. The JsonSerializer also checks whether the JSON text actually is
> valid. The organization of the classes follows the encoding serializers (such
> as the EncodingHTMLSerializer).
