Description

The ParameterDescriptor of the following operations use a java.nio.file.Path value:

• North American Datum Conversion (NADCON)
• National Transformation version 2 (NTv2)
• Geocentric translation by Grid Interpolation (IGN) (FranceGeocentricInterpolation)

We should replace the Path value by URI for the following reasons:

• Path are not serializable (SIS-567)
• ParameterValue needs unambiguous textual representation. This is required for encodings such as WKT or GML. But Path.toString() is not defined as rigorously as URI.toString().
• Path can not be used for HTTP or FTP files by default (it could be done with custom FileSystem however).

The use of java.net.URI would avoid those issues.
