Digital Media Project (DMP)Value Chain Functions, Requirements

And Architecture

Marc Gauvin Requirements


Value Chain Functions, Requirements


1. Industry agnostic specifications 2. Extendable Tool box approach3. Anticipated multiple Tool providers for lower uptake

cost;4. Full interoperability within a given Value-Chain;5. Enhanced interoperability between varying Value-

Chains;6. Innovation can be continuously fed in the system.7. DRM requires more than technology

The Goal

Requirements for Interoperable DRM Platform


For whom

Author Performer CMS Producer Publisher Syndicator Metadata Service provider Mediation Service provider Resolution Service provider Monitoring Service provider Repository Marketer Aggregator Retailer

Technology licensing provider Device Manufacturer Connectivity provider Network Service provider Platform Service provider Security provider Certificate Authority Conformance certification provider Clearing House Financial Service provider End-user Reseller Public Authority


Who Contributed?

Civil Rights Associations Association of People with Special Needs Individuals Collective Management Societies Producers Public Service Broadcasters Sheet Music Publishers Telecommunication operators Device Manufacturers


1. Use Cases identified and documented;2. Primitive Functions singled out;3. Functional Requirements;4. Tools to be standardised;5. Calls for Proposals for Tools + Requirements issued;6. Tool Selection through open process. DMP Favours Tools that are

already: Developed Standardised by other bodies Adaptable to DM;

7. Tool Specification;8. Calls for Proposals for subsequent Tools for:

new identified Primitive Functions new required functionalities of existing Tools.

DMP approach


Primitive Functions

Represent Identify Recognize Revoke Authenticate Verify Negotiate

Report Deliver Manage Package Process Transact Test Conformance Certify


Example: Represent Use Data

Detailed description of Requirements

Definition The syntax of the information used to describe the elements making up one or more instance of Use of Content, Device or User so that it can be Processed by a Device

Objective To enable processing of Use Data in a predictable fashion

Requir-ements

Ability to Identify Use Data Ability to support protection of Use Data Ability to convert Use Data to a human readable form Ability to not Identify User or Device associated with Use Data Ability to Represent a wide range of Content Uses e.g. time of Use,

combinations of Content Items, Domains, Super-distribution Uses

Benefits Provide a machine-processable record of Uses


Architecture & Value Chain Walk Through


Architecture

A walkthrough exercising the main elements of Value-Chains enabled by the Tools

The operating principles of Certification and Registration Authorities/Agencies
