3.1

aggregation

process of combining e-textbook components (3.2) to form new composite components (3.3)

3.2

atomic component(s)

smallest unit of content component that can no longer be divided

3.3

composite component(s)

component (3.2) that is composed of at least two other content components

Note 1 to entry: A composite component is one of two types of content components forming part of the content structure of the e-textbook Information Model. The other is an atomic component.

3.4

digital content

usable information in an e-textbook (3.9) , either as a single or multiple logical unit(s)

Note 1 to entry: Digital content will generally depend on appropriate software services that may be required to render or deliver other functionality associated with the digital content.

Note 2 to entry: A logical unit of usable (or re-usable) information is a logical package.

Note 3 to entry: A logical package may contain one or more logical units of digital content.

3.5

digital learning content

digital content (3.6) displayed within an e-textbook (3.9) including both static and interactive items for use in LET

3.6

digital content

single or multiple logical unit(s) of useable information in an e-textbook (3.9)

Note 1 to entry: A digital resource can be referenced via an unambiguous and stable identifier in a recognized identification system (e.g. ISBN, ISAN, UPC/EAN, URI).

3.7

e-book

structured digital content (3.6) in which searchable text is prevalent, and which is often seen as a metaphor of a printed book or pamphlet

Note 1 to entry: An e-book is usually an aggregation of digital content compressed into a single document, and from this perspective is regarded as a content package.

3.8

e-reader

computer hardware with appropriate software capable of loading and rendering an e-book (3.7) and providing functional support required to deliver digital content (3.6)

3.9

e-textbook

structured aggregation (3.1) of digital content (3.6) intended to support LET activities and which uses an e-textbook reader (3.12)

3.10

e-textbook fixed page

virtual surface of controlled size, and fixed layout (3.14) , for the purposes of displaying digital content (3.6) of an e-textbook (3.9)

3.11

e-textbook flowable page

virtual surface whose size and geometrical properties can be adapted to the e-textbook (3.9) reader or user choices for the purposes of displaying digital content (3.6) of an e-textbook

3.12

e-textbook reader

hardware with the appropriate software capable of loading and rendering an e-textbook (3.9) and providing the functional support required to deliver interaction (3.14) and learning support (3.18)

3.13

fixed layout

digital content (3.6) that is attached to a particular position on an e-textbook fixed page (3.10)

3.14

interaction

behaviour and data exchange within an e-textbook (3.9) context that occurs between a user and the digital content (3.6)

Note 1 to entry: Substantive changes do not include standard embedded video controls (start/stop/pause/fast forward, etc.) or changing presentation (e.g. increasing font size, highlighting, zoom, etc.).

3.15

ITLET system

set of one or more computers, associated software, peripherals, terminals, human operations, physical processes, information transfer means, that form an autonomous whole, capable of performing information processing and/or information transfer

[SOURCE: ISO/IEC 20006‑1:2014, 4.12]

3.16

learning device

computer hardware capable of accessing an e-textbook reader (3.12) and running an e-textbook (3.9)

Note 1 to entry: Computer hardware used to support learning, education and training capable of accessing an e-textbook.

3.17

learning service

processes or sequence of activities designed to enable learning

[SOURCE: ISO 29990:2010, 2.13]

3.18

learning support

functionality that is initiated by interaction (3.14) with an external service or digital content (3.6)

3.19

media

digital assets, which may include separately or bundled together, text, audio, video, image, pictures, animation, or graphics within an IT system.
