IPR rules
At the beginning of the meeting, the chair read the following text to the attendees:
INTELLECTUAL PROPERTY RIGHTS RULES This meeting is being held under the Intellectual Property Rights Policy of the Advanced Media Workflow Association. By signing in and attending this meeting, you have agreed to be bound, and your employer, if a member of the AMWA, is already bound, by that policy. If you are unfamiliar with that policy, please ask the Chair of this meeting, and s/he will provide you with a copy of that Policy. At this time, I would ask that anyone in attendance inform me if they are personally aware of any claims under any patent applications or issued patents that would be likely to be infringed by an implementation of the specification or other work product which is the subject of this meeting. You need not be the inventor of such patent or patent application in order to inform us of its existence, nor will you be held responsible for expressing a belief that turns out to be inaccurate.
Comments on IBM Proposals from 12th Oct Webex
Sony explained that they were basically in agreement with IBM’s proposals made in the previous Webex, while seeking some clarifications.
- Asynchronous Interface
- Media Container/Descriptor
Agreed in principle to use BOM approach for the NAB demo.
- Service I/F parameters on "Capture", "Transform", and "Transfer" (FIMS Proposals Match up)
ACTION ITEM: IBM said they would provide a schema for further study.
Concerns were expressed that technical metadata (e.g. for capture/file transport) should not be ‘opaque’. It was clarified that such metadata, while not directly exposed, is indeed intended to be internally available. There was a discussion on what should be the minimum set of technical metadata.
ACTION ITEM: Jean-Pierre said the EBU had been working on technical metadata as part of the SP/HIPS activity and would send a link to a technical document.
Proposal for FIMS Framework Reference Model
- Positioning of Seven Media Centric Issues within FIMS Framework
ACTION ITEM: All – in relation to composite services, consider what are the atomic operations we should consider.
Concerning Capture, duration is required. This could be Start + duration + frame rate. In the case of multiple clips, destination names may be indicated by the output file names. This would not be mandatory but, for example, ‘best practice’ might be that the capture device will increment output filenames with a number starting from “1”
David Carroll mentioned the issue of optimizing system operation when a single device has multiple atomic services internally; there may be a need for an ‘optimization layer’.
ACTION ITEM: All - collect use cases for composite services
- FIMS Framework specification milestones
- FIMS Framework for NAB 2011
There was discussion of the minimum interoperability required between systems, including the need to identify the correct vocabulary.
ACTION ITEM: When the preliminary draft is posted, take a view among FIMS vendors on what is the minimum common metadata.
Concerning M-SLA, it would be helpful to reference SLA IT frameworks, if possible.
ACTION ITEM: take a high-level view of Orchestration
Any Other Business
Preliminary working draft specification: IBM asked for a copy of the preliminary working draft ‘template’ that David had started to work on (this was sent following the Webex).
ACTION ITEM: Sony and IBM to update their respective sections of the preliminary working draft in advance of next meeting
ACTION ITEM: post updated preliminary working draft to Wiki, as soon as possible
Next face-to-face meeting
Provisionally agreed as: IBM, Hawthorne, NY: 15-16 November 2010 [subsequently proposed to be 11th (pm), 12th (am), 15th (pm)]
