Hi all,
Time to step in I guess ;-)

- CSW harvesting in GeoNetwork IS finished. It is based on version  
2.0.1 of the CSW specification and is the OGC reference  
implementation for that spec. Upgrade to CSW 2.0.2 is planned/ underway.
- CSW server is also available

- OAI-MPH has just been committed to SVN (both server and client (for  
harvesting))

- OpenSearch with the GEO extension is also available from the SVN  
version. We had a discussion with Andrew Turner

- GeoRSS search is also available as well as direct xml based  
services to search and present

- Harmonization between DC, FGDC and ISO19115/19139 is also  
implemented in GeoNetwork and has been available for a long time (2  
years if considering ISO19115:draft and in v2.1 including 19139  
encoded metadata)

A BIG problem for now considering the simple DC profile is that there  
is no place to put the service URL's for W*S etc.... I asked Jo and  
Stefan, browsed myself, but did not find it. Making sure such URL  
placeholder is in place is essential to make it worthwhile using the  
simple protocols. Anyone? If I know how, I can add it to the current  
DC formatted output and you all have your requested service output.

- We set up a 2.1.0 based version of GN yesterday on the telascience  
server. It could be scheduled to pick up properly formatted metadata  
XML documents from a folder on a (the same, another webdav) server.  
You can than use the GUI web editor in GeoNetwork or simply put XML  
records in a folder.

- A thing that would be a great to have, and I know there's many  
attempts already, is to have a Python script or so that asks the  
author to feed basic information (contact details, title, abstract,  
W*S server URLs) and uses GDAL/OGR to extract necessary data  
properties to put into a properly formatted metadata file. That file  
again can be automatically harvested if manually publishing is to  
involved.

- I think that in the latest gvSIG software one can now automatically  
generate basic metadata and edit it. From gvSIG this can be pushed  
into a GeoNetwork catalog directly.

- We will release a plugin to ArcGIS 9.2 soon that allows a user to  
publish metadata and data to GeoNetwork directly from ArcCatalog.

- We'll also release a stand alone metadata editor that uses GDAL/OGR  
to fill out basic metadata

I don't think we can make metadata life much easier than that ;-) If  
you want, come to the Third GeoNetwork workshop in November and  
you'll return home as a metadata/ catalog master ;-)

Ciao,
Jeroen
