One of my tasks is to work on getting the EcoGrid registry up and 
running (bug 1040).  I have been evaluating the use of the Grid 
technologies, and in particular Globus Toolkit 3.0, for this service 
(bug 1061).   I have managed, with considerable difficulty, to install 
the gt3beta release of Globus Toolkit on ecogrid.ecoinformatics.org, and 
I have set up a certificate authority there for generating GSI 
certificates.  The GT3 release has a built in metadata management 
facility (Information Services), as well as a Registry implementation. 
This seems to work as advertised, although I do not yet understand the 
toolkit well-enough to fully evaluate it.  It is a rich, complicated 
system and it'll take a while to fully understand it.

One thing that would be useful would be to test the registry by trying 
to register some services that we might be putting up for EcoGrid.  The 
two that come to mind are 1) the Query Service, and 2) the Taxonomic 
Name Resolution Service.  To do this, these services will need to 
implement a couple of Grid specific methods.  I would like to explore 
adding these into our interface definitions.  Dave -- do you think this 
would be a problem in any way for the Query Service or the Name 
Resolution service?  The methods needed are described in the Globus 
documentation [1]. Or alternatively we could extend their implementaiton 
classes which provides much of this functionality.  Once we have a WSDL 
describing the service, we could then just register the WSDL.

If you'd like to experiment with this Grid, please let me know and I can 
generate a GSI certificate for you and let you know the connection 
details for the GT3beta install.
