Module Status

The validation module is stable.

IP Check

Brent Owens sent the following email to the list on April 17th, 2006

I have nearly completed the IP check on the validation module of Geotools.

All the headers have been verified and corrected. I have also received word from Paul Ramsey (Refractions Research) that all the code in the module has been given to the community.

Here is a list of files that had their headers changed (some had duplicate headers):
DefaultFeatureResults.java
DefaultFeatureValidation.java
DefaultIntegrityValidation.java
FeatureValidation.java
IntegrityValidation.java
PlugIn.java
Validation.java
ValidationBeanInfo.java

Future Plans

The validation module depends on an the definition of a "typeRef" basically encoding a "datastoreId:::typeName" into a string for lookup into a Registry. The registery interface is provided by GeoServer (and also by uDig) as a way of letting integrity tests lookup a feature source to verification.

The is a bad idea for two reasons:

it is not strongly typed
it causes confusion with the namespace:typeName used during GML output

There are two solutions:

use the TypeName (extends Name) from GeoAPI, as provided for in 2.3 Feature Model development
use the Catalog System IGeoResource (an actual resource handle)

Both offer strong typing and avoid the possibility of confusion.
