Introduction It happens to announce shelter areas or locations before or after nature disasters occur. A hill area could be declared as a shelter area for being safe from a flood threat. LoST client can find out what instances of this service are closest to users. Examples include earthquake shelter, flood shelter, air-raid shelter, wildfire etc. We introduce new services to find the safe areas near to a client's location. And a LoST client can request for the particular service to know about the shelters near his location. A user can go to any shelter and ask for help, normally the nearest is the best. This is not like the police service, which has a clearly defined jurisdictional boundaries. So it's always advised to search for a shelter near to a specified location. 2. Terminology used in this document The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. 3. Sub-Services for the 'shelter' service This section defines the shelter service registration using the top- level service label 'shelter'. This kind of service could be required in a wide range and in a short period. urn:service:shelter urn:service:shelter.airraid urn:service:shelter.earthquake urn:service:shelter.flood urn:service:shelter.heatwave urn:service:shelter.homeless urn:service:shelter.hurricane urn:service:shelter.wildfire Note: The corresponding description for each service will be added in the later version. 4. Example for finding shelters In this example, we use the circular shape in queries and serviceLocation element in responses introduced by [LOST-EXT]. The Sun & George Expires January 4, 2009 [Page 3] Internet-Draft Shelter Service July 2008 element contains the geodetic coordinates of a point of service and must be contained in a element. In responses such as , a list of service URIs, each with its own element, must be returned. 37.775 -122.422 2000.24 urn:service:shelter.earthquake Figure 1: A query The client is asking the LoST server to send a list of service URNs and earthquake shelter places within 2000.24 meters from its approximate position specified in .
