[Geotools-devel] GeoAPI-SNAPSHOT updated with ISO 19115 interfaces

[Martin D. <mar...@te...>]

Hello all

I just updated geoapi-SNAPSHOT on iblio. The new GeoAPI JAR file 
contains ISO 19115 interfaces, which can be browsed online here:


    http://geoapi.sourceforge.net/snapshot/javadoc/index.html


Note that in order to compile Geotools with this new JAR, developper 
will also need to do a SVN update.



This API is a realization of ISO 19115 
(http://www.opengis.org/docs/01-111.pdf) as straightforward as I can. 
There is no interfaces or methods addition compared to ISO 19115. 
However, the API will probably change according GeoAPI mailing list 
feedback. For example we plan to replace arrays by java.util.Set.

org.opengis.metadata.MetaData and Identification contains all methods 
found in org.geotools.metadata.iso19115. Concequently, the later could 
be removed. Key differences are:

   - org.opengis.metadata has no MetaDataElement interface, because I
     didn't found it in ISO 19115. However, we could add it if a
     request is send to the GeoAPI mailing list.

   - Methods in MetaData and Identification returns the more accurate
     type instead of the generic MetaData[Element]. However, most
     method names are the same.


This also bring an other issue. There is already an 
org.geotools.metadata.MetaData class, which is a different beast than 
org.opengis.metadata.MetaData. In the approach I took up to now, all 
org.geotools.XXX classes are implementations of org.opengis.XXX 
interfaces (i.e. I just replace "opengis" by "geotools" in the fully 
qualified name). If we choose to continue that way, 
org.geotools.metadata.MetaData should be an implementation of 
org.opengis.metadata.MetaData. This means that current 
org.geotools.metadata.MetaData should be moved in an other package. 
Maybe some org.geotools.metadata subpackage? What do you think?
