RE: New User Discovery Use Case

Thanks JP (I think - I spent much of today reading/scanning through the TVA
documents, in particular parts 1, 2, and 4 with a quick look at parts 5, 8
and 9). I was aware of TVAnytime but not the details. You are right, a lot
of information and examples are there. I didn't see anything on having the
client criteria as being part of the user's search criteria although that
might be implicit in the user search criteria. If I understand it correctly
the user inputs their search criteria which is received by a service that
returns CRID(s) that meet the criteria. The client criteria, if included,
would further narrow what is returned and might be useful in narrowing
location resolution. I also see cost data can be requested/returned for the
various content CRIDs. 

 

I noticed that there is no authority to assign CRIDs and I didn't see how
that would be done. Probably in another document. However, it appears a
given CRID may be reusable (may have an expirataion date) which would be a
problem if it is added as a watermark or fingerprint to content which are
fixed for all time once added. Thus any CRID used to watermark would have to
be permenent (no expiration). While that appears to be an option, I am not
sure if it is possible to ensure there is no possibility of duplication and
if, without an authority, the CRID approach would be able to accommodate the
large number of content IDs required for what GGIE envisions. Feel free to
comment on my observations and TVA's applicablility to what GGIE is doing. 

 

Any comments on the UC I posted? And do you have any User Discovery UCs you
want to post? 

 

Thanks for the reference.

Hello Bill,

 

Thanks,

 

Do you know the TV-Anytime specification ?

 

I contains a lot about user description, user modes of content consumption,
content description, all in order to facilitate search and recommendations.

 

In addition to this, all TVA mechanisms for describing broadcast and
on-demand publication events and associated services have been introduced in
an earlier version od schema.org.

 

The TVA data model is also actually RDF ready.

 

If you need more information.

 

Best regards,

 

Jean-Pierre

Resending - My appologies if you get 2 copies of this. I had not set my
permissions to post W3C message archives. - Bill 

 

I posted a Use Case for GGIE User Discovery at
https://www.w3.org/2011/webtv/wiki/GGIE_TF/UseCases/User_Discovery to get
the discussion started on this subject. Its an extension to Streaming UC-1b
adding client information to the search criteria. As I am new to this feel
free to edit, comment, make suggestions - including that it does not belong
here, or whatever. Also, feel free to post new User Discovery Use Cases or
discussion topics.
