Identifier connection object

[brechtvdv]

What namespace should we use for the identifier of a connection-object?
Should we make a hash from the departureTime as index to be more future proof or is a counter good enough for now?

{ "@context" : 
   {
         "connection" : "http://linkedconnections.org/connections/[agencyId]/",
         "..." : "..."
   }
}
{"@type" : "Connection",
 "@id" : "connection:1",
 "..." : "..."
}

It should be able to be configured

I'd add a baseuri to the constructor for the connections, and make the @id of a connection on the basis of the time of departure (e.g., in unixtime) concatenated with the stops identifier and e.g., the trip id
