Martin,

For the feature mapper I think we would need an interface that would
define the contract of mapping from one feature to another. This
interface would be defined to work with a single schema.

public interface FeatureMapper {
  Feature convert(Feature feature);
}


There would be a default implementation that can be configured by
specifying the source and target FeatureSchema and a map from source to
target attribute names. This can be used by plug-ins or even better
configuration files to create simple mappings.

There is also need for a more complex mapper that can create attribute
values using some kind of processing (e.g. a Point from attribute
converter), this could also be done in a configurable approach.
