3.1

access

right, opportunity, means of finding, using, or retrieving information

[SOURCE:ISO 5127: 2017, 3.11.1.01]

3.2

attribute

characteristic of an object or entity

Note 1 to entry: Adapted from ISO/IEC 11179-3:2003.

[SOURCE:ISO 23081-1:2017, 3.3]

3.3

content information

set of information that is the original target of preservation or that includes part or all of that information

[SOURCE:ISO 19165-1:2018, 3.6]

3.4

data cleansing

process used to improve data quality by detecting and correcting (or removing) defects and errors in data

[SOURCE:ISO 5127:2017, 3.1.11.21]

3.5

data object

discrete data, considered as a unit, representing an instance of a data structure that is known or assumed to be known

[SOURCE:ISO/IEC 2382:2015, 2121425]

3.6

emulation

recreation of the functionality and behaviour of an obsolete digital system, using software (called emulator) on current computer systems

Note 1 to entry: Emulation is a key digital preservation strategy.

[SOURCE:ISO 5127:2017, 3.12.1.20]

3.7

encryption

(reversible) transformation of data by a cryptographic algorithm to produce ciphertext, i.e. to hide the information content of the data

[SOURCE:ISO/IEC 18033-6:2019, 3.8]

3.8

file format

encoding of a file type that can be rendered or interpreted in a consistent, expected and meaningful way through the intervention of a particular piece of software or hardware which has been designed to handle that format

Note 1 to entry: A file may (or may not) be a container containing zero or more files of various formats. File formats may be defined by a specification, or by a reference software system. Many file formats exist in forms with minor variations and many also in more than one version. Typing of file formats should be interpreted generously rather than strictly, but sufficiently precisely to distinguish versions where such distinctions have significant interpretive consequences.

3.9

migration

process of moving records from one hardware or software configuration to another without changing the format

3.10

originating

initial manifestation of something

3.11

preservation

measures taken to maintain the useability, authenticity, reliability and integrity of records over time

Note 1 to entry: Measures include principles, policies, rules, strategies, processes and operations.

[SOURCE:ISO 30300:2020, 3.4.11]

3.12

refreshment

digital migration where the effect is to replace a media instance with a copy that is sufficiently exact that all archival storage hardware and software continues to run as before

[SOURCE:ISO 19165-1:2018, 3.31]

3.13

replication

digital migration where there is no change to the packaging information, the content information, and the preservation description information

Note 1 to entry: The bits used to represent these information objects are preserved in the transfer to the same or new media instance.

Note 2 to entry: Adapted from ISO 14721:2012.

3.14

representation information

information that maps a data object into more meaningful concepts

[SOURCE:ISO 19165-1:2018, 3.34, modified — Examples have been omitted.]

3.15

source record

document or record that has been copied, converted or migrated or will be the input for such a process

Note 1 to entry: Adapted from ISO/TR 13028:2010, 3.8

3.16

validation

process of evaluating a system or component to ensure compliance with the functional, performance and interface requirements
