DMP terminology

  

Terms defined in this document when used with upper case in other DMP documents have the meaning defined here, unless another meaning is explicitly declared. Note that terms beginning with lower case may not necessarily include entities expressed by terms beginning with upper case.

 DMP terms are presented in two views. In the first view terms are grouped by similarity in the following five classes 

General

Users

Systems

Data

Functions

 

In the second view terms are given in alphabetical order. 

 

Definitions grouped by similarity 

General

 

Approved Document

Any of the following types of DMP documents

  • Recommended Actions
  • Recommended Practices
  • Technical Specifications

Conformance

The satisfaction of a Device or a piece of Content to the relevant requirements of one or more than one Specification

Interface

The boundary between

  1. Devices
  2. Devices and devices
  3. Devices and Users
  4. Devices and Delivery System

Interoperability

The possibility for Users (including End-users) to technically execute value-chain Functions through Interfaces and Protocols of known specification

(Content) Interoperability

The ability of a piece of governed content to be used by a device. All DMP Governed Content is Interoperable with DMP Devices

(Device) Interoperability

The ability of a device to exchange data with other devices across standard interfaces using standard protocols. DMP Devices are Interoperable

Key

Data used by a cryptographic method

Protocol 

A description of data formats and rules a device must follow to  exchange those data with other devices.

Right

The ability supported by the applicable law to execute Functions on a piece of Governed Content

(Technical) Specification

A type of DMP Approved Document containing normative clauses. Its use in Devices, Contents and Services may require business agreements between relevant Users. Such business agreements are outside of DMP

Superdistribution

A mechanism that

  1. allows a User to distribute Content to recipient Devices through potentially insecure delivery systems and
  2. enables the Users of the recipient Devices to obtain a Rights Expression for the said Content.

Trust

A state of Users, Devices or Content Data the attainment of which enables the execution of Functions on Governed Content by Users

Trust Management

The mechanisms by which Trust can be established, preserved and severed

Users

 

Author

A User who creates a Work

Content Provider

Any User providing Content or Governed Content to another User (e.g. an End-user)

Producer

A User who produces Content

End-user

The last User in a Value-chain

Right Holder

A User who has Rights on a piece of Content

User

Any user of Content who is on a Value-Chain between (and including) Author, Creator and End-user. For the purpose of current Specifications a User is represented by a device or by a User Identity on the Device (e.g. username/password).

User Authentication

The procedure to prove the identity of a User to a Device, a Service or a Delivery System

Systems

 

Device Authentication

The procedure to prove the identity of a Device to another Device, a Service or a Delivery System

Delivery System

 

 A system that is used to deliver Data between any two or more Devices  (e.g. a storage medium or a network-based transport mechanism)

Domain

A set of Devices such that only the Devices belonging to that set can Use Governed Content intended for that set of Devices.

DMP DRM System

A set of Devices that  manages and protects Governed Content in such a way that any Device is technically enabled to Use Governed Content. A DMP DRM system implementation allows Devices to Use Governed Content from another DMP DRM System implementation even though the latter may use different technologies.

Environment

A Device or set of Devices with the same or different functionalities. An Environment may interact with other Environments and may also interact with the outside through appropriate Interfaces

Value-chain

A set of Users, including Authors, Producers and End-users

Data

(see figure)

Composite Content

A combination of different pieces of Content

Content

A structured combination of any Resource Type and Metadata

Content Data

A structured  combination of Content Data Elements

Content Data Elements

Any of the following Content Data types: Resources, Metadata, Content, Rights Expressions, Licenses and Governed Content

Descriptors

Data that describe the properties of Resources

Executables

Data that give a Device instructions to enable a User to execute Functions

Governed Content

A piece of Content combined with a License

Identifier

A symbol that establishes the identity of Users, Devices, Domains, Works and Content Data Elements

License

Metadata

Information (e.g. Identifiers, Descriptors etc.) not including Use Data, Rights Expressions and Licenses that is distinct from but directly related to Works and Resources.

Resource

The embodiment of information that can be rendered in a form that is meaningful to a User, e.g. an MP3 file

Resource Type

Any digital expression of Resources such as video, audio, audio-visual, text, synthetic audio, 2D/3D graphics

Rights Expression

The statement of Functions that can be performed on a piece of Governed Content and the circumstances in which they can be performed

Stateless Rights Expression

A Rights Expression that does not include any countable/temporal condition such as total played time, date, term, etc. Examples of Stateless Rights Expressions are those with conditions based on region code or until a certain date etc.

Use Data

Data that document the Functions (e.g. the number of times a movie is played) that a User executes on a piece of Governed Content

Work

Information which retains attributable properties independently of its manifestations in different pieces of Content

Functions

 

Content Access

The Function of making available Content or Governed Content to a Device so that a Device can execute Functions on it

Backup

The Function consisting of the following actions

  1. Duplication of Content.
  2. Duplication Rights Expression in case this is a Stateless Rights Expression
  3. Moving of the duplicate(s) to another location that is not a Device

Copy

The Function consisting of the following actions

  1. Duplication of Content and/or Rights Expression
  2. Transferring that duplicate to another Device

Function

What is executed by a Device on Governed Content

Move

The Function consisting of the following actions

  1. Copy of Content from a source Device to a destination Device
  2. Deletion of said in the source Device

Quote

The Function of extracting a piece of Content from or referencing another piece of Content

Render

The generation of human-perceivable data on an appropriate device

Restore

The Function of moving Content and the associated Stateless Rights Expression  if any to the Device from which Backup had been performed

Stream

The Function of transferring Content to a Device in real-time where the transferred Content is processed for Rendering only

Service

A set of Functions executed by a User on Content that is valuable for another User or Users

Trick Modes

Any of the following Functions performed on a piece of Content during Rendering by a User:

  1. fast forward
  2. slow motion
  3. freeze frame
  4. fast reverse
  5. slow reverse
