Here is a short summary of the gin-info session at OGF18. Please let me 
know if there are any omissions or mistakes. If requested to do so, I 
could also put this summary on the wiki page.

Summary:
The presentation given in the gin-info session has been attached to the 
bottom of the Wiki page.

The presentation gave the current status of the group  A great deal of 
work has been done on translators between information systems. For each 
participating infrastructure an information provider has been created 
which queries that infrastructure and outputs the information in LDIF in 
accordance to the Glue Schema.  These information providers were used to 
setup a BDII (gin-bdii.cern.ch) that contained information from the 
participating infrastructures. Using this information different use 
cases can be tried. The first use case selected was the "site on a map" 
use case.  For this use case, three values are required;  an identifier 
for the site, the latitude and the longitude.  Using this information it 
was possible to use Google Earth to show the location of the sites and 
the grid affiliation.  The conclusion of this work was that to query on 
information system and populate another was straight forward. The 
limiting factor was the information available in the information 
systems. The information required will be defined by the use cases and 
hence we need to identify information required for the "cross-grid" use 
cases.

Outcome of Discussions:
The NGS infrastructure would like to be included in the gin-bdii
The DEISA infrastructure would like to be included in the gin-bdii
gin-jobs would like to be able to find all the Computing Services to 
which the GIN VO has access.

Action List:
Ensure that the Google Earth demonstration is in good shape for SC06
Add NGS to gin-bdii
Add DEISA to gin-bdii
Ensure all grids publish the information required for the site on a map 
use case
Agree on the information required for the gin-jobs use case.
Ensure all grids publish the information required for the gin-jobs use case.
