DMP Reference Software

1. DMP Reference Software Martin Springer Contributor to the DMP Chinese Academy of Sciences Beijing, 2005/10/13 DMP Reference Software

2. Two faces of DRM • It can help preserve and enhance the status quo • High threshold to entry content distribution • Control of distribution, sealed against competition • Existing business models can continue • It can help break the status quo • Low entry threshold to content distribution • A competitive market where quality of content determines success and not control of distribution • Support business models for many small target groups (not only mainstream media, but also niche content) • It can help the unknown creator to make himself known… DMP Reference Software

3. DMP and DRM interoperability • The basic DMP position • Digital technologies are an asset of mankind • Creators, intermediaries and end-users should all benefit from them • Standardisation of appropriate Protocols between value-chain users supporting the Functions they perform achieves this goal • DMP definition of interoperability: • The technical ability of value-chain users to perform functions through interfaces and using protocols of open specification that can be independently implemented and provide predictable results DMP Reference Software

4. Value-Chain • A group of interacting Users, connecting (and including) Creators to End-Users intermediary End-User Creator DMP Reference Software

5. The DMP Process • Ask people to state their needs • From the needs derive Functions • Derive requirements for the Functions • User requirements • Functional requirements • Identify prominent use cases • Issue Call for Proposals for technologies • Select component technologies (Tools) • Develop specifications in phases DMP Reference Software

6. User • Any person or legal entity in a Value-Chain connecting (and including) Creator and End-User. User DMP Reference Software

7. Device • A system conforming to Approved Documents that allows a User to execute Functions. Device DMP Reference Software

8. Function • An action specified by DMP Function DMP Reference Software

9. Some Primitive Functions DMP Reference Software

10. Tool • A technology capable of implementing a Function • Examples of Tools • Identification of Content, Device, User etc. • Expression of Rights to Content etc. • Authentication of Devices DMP Reference Software

11. Interoperability • Users perform Functions through Interfaces and using Protocols of open specification • Users pick the Tools they need License Work Content License Register Certify Process Decrypt Decode Create Encrypt Store... Identify Access Function DMP Reference Software

12. Toolkit standard for DRM • A toolkit standard is • A standard specifying component technologies (tools) • Users build solutions picking the tools they need • Benefits of a toolkit standard • Value-chains are implemented as combinations of tools • Reduced technology cost because tools • Are provided by multiple suppliers • Can be re-used in different value-chains • Interoperability is provided at tool level DMP Reference Software

13. The DMP Phase II Approved Documents (IDP-2 Working Drafts) DMP Reference Software

14. Objectives of DMP reference software • Understand DMP Approved Documents • Develop software modules for Tools • Implement Use Cases • Content Creation Device (CCD) • eXternal Device (XD) • Content Consumption Device (PAV) • Content Consumption Device (SAV) • Content Identification Device • Content Provider Device • License Provider Device • Device Identification Device DMP Reference Software

15. Content Creation Device (CCD) -Use Case walkthrough • Creator activates an application on his CCD. The application shows a user interface displaying a series of steps that the Creator will follow: • Selects the DCI from a number of available DCI templates • Gets Resources from outside the CCD • Obtains a Resource Identifier • Has the option to Encrypt Resources • Fills the Metadata template for each Resource • Has the option to obtain Metadata Identifier • Selects a License from a number of available License templates • Obtains a License Identifier • Has the option to Store the License on a License Provider Device or to Bundle the License within the DCI • Obtains a Content Identifier • Creates a DCF • Stores the DCF on a Content Provider Device DMP Reference Software

16. Content Creation Device (CCD) -Architectural Model DMP Reference Software

17. Licenses of DMP reference software DMP Reference Software

18. Important issue • Who implements the reference software? • Commercial implementations (economically profitable) • Non-commercial implementions (academically profitable) • Reference software requirements • Open Source (see license) • Available for many OS (e.g. Java, GNU compiler) • Available to many developers and implementers • No expensive hardware (e.g. PC) • No expensive development environment (e.g. Linux, CVS) • No expensive IP (if possible no software patents) • Available for end-to-end conformance testing (Test suite) DMP Reference Software
