Last Call Review of draft-reed-urn-dgiwg-
review-reed-urn-dgiwg-secdir-lc-roca-2011-05-19-00

Hello,

I have reviewed this document as part of the security directorate's
ongoing effort to review all IETF documents being processed by the
IESG.  These comments were written primarily for the benefit of the
security area directors. Document editors and WG chairs should treat
these comments just like any other last call comments.

This document introduces a new namespace for the DGI Working Group
(

http://www.dgiwg.org

) and has a very light security considerations
section (1 sentence only), as is usually the case with such documents
(see 

http://www.iana.org/assignments/urn-namespaces/urn-namespaces.xml

).

That being said, since the goal of the DGIWG is to facilitate the
exchange of geospatial information between countries, in particular
in context of military cooperations, security is critical. Therefore
the author could perhaps elaborate a little bit more.
For instance one or two sentences highlighting the importance of 
having secure methods to access locations once the URN resolution
has taken place (i.e. after the name to location resolution) could
be added, with a few pointers.

Regards,

   Vincent
