Hi all,
draft -14 states regarding multiple entries in the directory:
It is possible that multiple entries in the directory match a desired
Information Resource. For instance, in the example in Section 7.6.3,
a full Cost Map with "numerical" Cost Mode and "routingcost" Cost
Type could be retrieved via a GET request to
"http://alto.example.com/costmap/num/routingcost";, or via a POST
request to "http://custom.alto.example.com/costmap/filtered";.
Is my understanding correct that a directory response with duplicate entries
for the exactly same service (including the same cost mode etc.) is allowed as
well?
Example for network map:
HTTP/1.1 200 OK
Content-Length: 1472
Content-Type: application/alto-directory+json
{
"resources" : [
{
"uri" : "http://alto.example.com/networkmap";,
"media-types" : [ "application/alto-networkmap+json" ]
},
{
"uri" : "http://alto2.example.com/alternative/networkmap,
"media-types" : [ "application/alto-networkmap+json" ]
}
]
}
We just wonder what an ALTO client should do if it gets such a response -
probably it would pick a random URI. This could actually achieve some simple
load balancing.
Thanks
Michael
