Dear Robert Jones,

Thanks for your email!

The CSW 2 interfaces have been implemented on GeoNetwork opensource for release in version 2.1. We have some related parts of the application that are currently upgraded to support the ISO19139 formatted metadata before we can release 2.1. The source code for the CSW2 implementation is available in the HEAD of the CVS on sourceforge. The implementation is based on the ISO19115/19119 profile.

I have copied Andrea Carboni who is working on the implementation, he can provide feedback on what the status is. I also copied the GeoNetwork developers mailing list for information.

Due to an upcoming workshop we have next week, I'm not sure how quick Andrea is able to react.

Regards,
Jeroen

Dear Sir/Madam,

We are interested in becoming involved in the development of GeoNetwork OpenSource 2, specifically the CSW 2 interface element. I note that the presentation at this URL - http://y.eogeo.org/files/eogeo2005/7-ticheler-eogeo-2005.ppt - states that release 2.1 will include the CSW 2 interface. If possible, please could you inform me how far development has progressed towards CSW 2 compliance, and whether there is a chance of a release including the interface in the near future?

Many thanks,
Robert Jones

Hi Robert,

here is the current status (and issues) of the CSW implementation:

- The new ISO 19139 has been taken into account to implement the CSW.
  Because this standard is not final yet, we used the schema present at the
  address http://www.isotc211.org/schemas/2005 which is updated up to March
  2006.

- We used the ISO profile which is not final yet. This leads to some anomalies
  that we hope to fix in the near future. Without fixing these, I don't think that
  a catalogue implementation can effectively communicate with another.

- The implementation is almost finished. We have implemented the following
   operations: GetCapabilities, DescribeRecord, GetRecordById, GetRecords.
   What is missing is:
    - the DescribeRecord is not finished because it is not clear what it should return.
    - the stylesheet to convert a filter expression into a lucene query (for the
      GetRecords operation)

- The CQL parser is pretty trivial (it uses a small existing parser). You cannot
   handle complex queries with that.

- The CSW code is modularized into client-common-server modules. There is a
  client GUI to test CSW capabilities and a small common library to simplify
  the development of Java clients.

- We have almost finished a set of stylesheets to convert from the ISO19115 to the
   ISO19139 standard.

- Before releasing GeoNetwork 2.1 we have to decide how to manage the editor because
  the XML schema of the 19139 is pretty complex and our parser is not strong enough.
  We have to decide between improving the parser (and delaying release 2.1) or not.

- At the workshop we will decide how to drive both the specification and the
  implementation of the CSW.

Cheers,
Andrea
