2005/10/12DMP Reference Software2 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…

2005/10/12DMP Reference Software3 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

2005/10/12DMP Reference Software4 Value-Chain A group of interacting Users, connecting (and including) Creators to End-Users Creator End-User intermediary

2005/10/12DMP Reference Software5 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

2005/10/12DMP Reference Software6 User Any person or legal entity in a Value-Chain connecting (and including) Creator and End-User. User

2005/10/12DMP Reference Software7 Device A system conforming to Approved Documents that allows a User to execute Functions. Device

2005/10/12DMP Reference Software8 Function An action specified by DMP Function

2005/10/12DMP Reference Software9 Some Primitive Functions

2005/10/12DMP Reference Software10 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

2005/10/12DMP Reference Software11 Interoperability Users perform Functions through Interfaces and using Protocols of open specification Users pick the Tools they need Function Create Encrypt Store... Register Certify Process Decrypt Decode Identify Access Work Content License

2005/10/12DMP Reference Software12 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

2005/10/12DMP Reference Software14 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

2005/10/12DMP Reference Software15 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

2005/10/12DMP Reference Software16 Content Creation Device (CCD) - Architectural Model

2005/10/12DMP Reference Software17 Licenses of DMP reference software Technology/specReference software If no patents existOS (Open Source license) If patents exist, license patents under RAND terms QOS (license to modify and use if DMP-conforming) From another body w/ reference software Existing license, if OS- or QOS-compatible From another body w/o reference software OS, if possible, otherwise QOS

2005/10/12DMP Reference Software18 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)
