Title

Requirements for Interoperable DRM Platform and Interoperable End-user Devices

No.

040205chiariglione01r02


This document is a contribution toward the identification of Requirements (RQ) to be used for the specification of Interoperable DRM Platform (IDP) and Interoperable End-user Devices (IED).

At the current stage RQs are at a rather high level. With the progress of the work it can be anticipated that individual RQs will spawn families of more specific RQs.

The seven-step process

This document should be read with the understanding that it just covers one (the 2nd) of a seven-step process:

# Step Status of work
1. Make a full “census” of Traditional Rights and Usages (TRU) of media users This is being done on the public DMP reflector
2. Use the full set of TRUs to develop RQs This is what the present document is about
3. Use the RQs to design IDP and IEDs This is part of the DMP program of work
4. Develop RQs for the use of IDP and IEDs This is part of the DMP program of work
5. Use the RQs to develop Recommended Practices for End-to-End Conformance (EEC) This is part of the DMP program of work
6. Let individual jurisdictions determine which TRUs shall be mandatorily supported in IDPs and IEDs operating under their jurisdiction and which TRUs are to be left to individual negotiations To be executed by relevant public autorities
7. Let users agree which EEC clauses should be referenced in their business agreements. To be executed by relevant users

This means that RQs given below should not be considered as absolute. E.g. a RQ like

  1. "DMP shall support continuous access to DMP content" should be interpreted to mean that in a hypothetical country where:

    1. usage rules are not legally supported, DMP end-users have the right to access DMP content they have bought for the period of time prescribed by the law

    2. usage rules are legally supported, DMP end-users have the right to access DMP content they have bought according to the usage rules.

  2. "DMP shall support the ability of a DMP user to publish DMP content anonymously" should be complemented by the words "of which he has the right" after "DMP content". The ways the DMP user has acquired the right can be manifold, e.g. because he is the creator of that piece of DMP content or because it is a quote or because the usage rules allow him to do so.

Definitions

In this document the following definitions apply:

Term Definition
DMP access The ability to access a piece of DMP content according to DMP specifications
DMP content Digital media designed to be used by DMP devices
DMP creator A DMP user who creates DMP content
DMP device A device designed according to DMP specifications that can use DMP content
DMP end-user A DMP user who uses DMP content
DMP quote A piece of DMP content extracted from another piece of DMP content
DMP right The legally-supported ability to use a piece of DMP content in accordance with DMP specifications
DMP right holder A DMP user who has rights on a piece of DMP content
DMP specification A DMP approved document. Its use in products may require business agreements between relevant DMP users that are outside of DMP
DMP user Any user of DMP content who is on the value chain between (and including) creator and end user
TRU (Traditional Rights and Usages) Any use of content that value chain users between (and including) creators and end users have traditionally performed as permitted, tolerated or unspecified by law

This section needs expansion.

Requirements

The requirements have been derived from the TRU list. More requirements will be added from existing or new TRUs as appropriate.

Note that each RQ starts with "DMP shall support"
