+Each object is assigned a UUID. This has the format @aaaaa-bbbbb-ccccccccccccccc@.
+
+# The first field (@aaaaa@ in the example) is the site prefix. This is unique to a specific Arvados installation.
+# The second field (@bbbbb@ in the example) is the object type.
+# The third field (@ccccccccccccccc@ in the example) uniquely identifies the object.
+h2. Timestamps
+
+All Arvados timestamps follow ISO 8601 datetime format with fractional seconds (microsecond precision). All timestamps are UTC. Date format: @YYYY-mm-ddTHH:MM:SS.SSSSZ@ example date: @2016-11-08T21:38:24.124834000Z@.
h2. ETags
fn1. Each response includes an ETag, a string which changes when the resource changes. Clients can use this to check whether a resource has changed since they last retrieved it. If a previous ETag is provided along with a request, and the resource has not changed since, the server may return a "not modified" response.
