Re: [Ecrit] Service Boundary and listServicesByLocation / New Version Notification for draft-wolf-ecrit-lost-servicelistboundary-00

["Karl Heinz Wolf" <khwolf1 at gmail.com>]

I discussed this topic with Hannes at the last Emergency Workshop and
he suggested to write a draft. So here it is:

A new version of I-D, draft-wolf-ecrit-lost-servicelistboundary-00.txt
has been successfuly submitted by Karl Wolf and posted to the IETF
repository.

Filename:	 draft-wolf-ecrit-lost-servicelistboundary
Revision:	 00
Title:		 Location-to-Service Translation Protocol (LoST) Extension:
ServiceListBoundary
Creation_date:	 2008-05-28
WG ID:		 Independent Submission
Number_of_pages: 8

Abstract:
LoST [I-D.ietf-ecrit-lost] is able to map service identifiers and
location information to service contact URIs.  If a LoST client wants
to discover available services for a particular location, it will
perform a <listServicesByLocation> query to the LoST server.
However, the response from the LoST server does not give information
about the geographical region, for which the returned service list is
valid.  Therefore this document proposes a ServiceListBoundary, in
addition to the ServiceBoundary (which indicates the region a
specific service URL is valid).
