I can see references in the docs to quality of service metadata (QoS).
Question is, how can I get on the end of it?
All I ever seem to get is layout metadata because thats the only namespace that is ever available
when I query getnamespaces method after a load/play trait event fires.
Hope that makes some kind of sense to somebody.
I am not sure if this answers your question, but given your subject line ...
Re QoS metadata, at the bottom of the OSMF features page (at the following url) currently states:
Planned for a future release after 1.0
* QoS data API (Flash Player 10 QoS APIs)
With 1.0 scheduled for late next month, this means QoS data API will be added only later.
