Title |
Abstract digital media value-chain functions |
No. |
0076/Los Angeles |
This document lists value-chain functions that are needed to perform value-chain roles and satisfy the following conditions
a. they are abstract in the sense that they are re-usable across the value-chain
b. they are primitive in the sense that they can no-longer be decomposed.
The list has been derived from the list of “Today’s value chain players” (DMP0074).
Entries in brackets represent items for further studies.
This is work in progress and is being discussed by an ad hoc group established by GA02…. with a view of finalising it at the Osaka meeting (GA03).
Definitions
| Content | Data and executables that are processable (e.g. renderable) into forms that are meaningful to users |
| User | a person or organisation |
| Value-chain player | a user who accesses the value chain using a device |
| Rights expression | the statement of which functions can be performed on a piece of content or content-related services |
| Value expression | the equating of two groupings of goods and/or services |
Primitive value-chain functions
Creation of content (includes variation, adaptation, combination)
Sharing of revenues (e.g. from royalties)
Requesting assignment of identifiers
(“Requesting assignment of” combined with “assignment of and, possibly, authentication, verification and certification” constitues the act of registration)
Requesting assignment of descriptors
Assignment of an identifier to an underlying work
Assignment of descriptors of an underlying work
Assignment of an identifier to a piece of content
Assignment of descriptors of a piece of content
Assignment of an identifier to a value-chain player
Assignment of descriptors of a value-chain player
Establishing a relationship between an identified piece of content and an identified value-chain player
Agreeing the terms of licensing
Expressing the terms of licensing
Publish a piece of content (making available a piece of content to a third party, at given conditions…)
Querying descriptors about content and value-chain players
Providing answers to queries on descriptors about content and value-chain players
Establishing relationship(s) between value-chain players (one-to-one, one-to-many, many-to-one)
Establishing a contract between one value-chain player and another

Giving a new structure to a descriptor data base
Giving remuneration (monetary, bartering, crediting, debiting account etc.) to a value-chain player for performing a function
Authentication of value-chain players (including devices)
Verification of value-chain players (including devices)
Certification of value-chain players (including devices)
Validation of certificates
Revocation of certificates
