WFS-X Architecture : a Web Feature Service with Transformation
A WFS-X connected to various WFS with 3 components:- one for schema mapping with many operators,- one for schema translation (of elements name),- one for content translation (text values)

Cocoon Mediator (‘Wrapper’, ‘Multi-tiered approach’) features
> Can map many schemas (multiple profile)
> Can merge several service results
> Mediator handles both structure and vocabularies (although for simple cases)
> Mediator can handle SLD and GetFeature translations
> Has an internal Deegree component and can target external WFS
