General definitions of terms used
throughout the development
of the Prometheus project.
Accessions Sheet
An Accessions Sheet is a registry entry
within the
Manuscripts Accessions Registry which is used to generate and to track
the various components of a specific donation or purchased lot within
manuscripts. An Accessions Sheet can have many Items or boxes and
associated sub-items.
Bibliographic Record
A Bibliographic Record is the
Bibliographic Record of an
intellectual work. A Bibliographic Record can have many Holdings.
Born
Digital
Electronic
records which are created within a digital manner in during day to day
business are referred to digitally created materials. They were not
intended to have an analogue equivalent (paper) and probably only exist
in digital form. They have a ‘formal’ status by Creator.
Catalogue Record
The Catalogue Record can either be a
Bibliographic Record or
an Accessions Sheet Record.
Digital
Holdings Persistent Identifier
A unique number
allocated by Prometheus Digital Preservation Workflow system to a
Digital Object (eg nla.dp-nXXXXX). This number can be used to provide a
future access link to a related Digital Preservation Job or Part.
Digital
Publications
These are
born digital objects which have been expressly released for wider
access and either distributed free of charge or for a fee.
Digital
Preservation
A
management series of actions required to ensure continued access to
digital materials for as long as necessary.
Digital
Preservation Work Flow
A
specific Workflow
which describes a digital preservation action, such as "Imaging an
Item", or "Normalising a File". When a User begins performing a
Digital Preservation Workflow, the specific Workflow which they begin
will
dictate the actions that are available to them. For example, starting
an
"Imaging an Item" Workflow allows the User to image media on their
computer, but not perform Normalization Actions.
File
A File is a single self contained
bitstream that exists on a
file system (such as FAT32 or ISO9660). The file may not be stored as a
continuous stream in its original form. This could be a JPEG picture or
a Word Document - there is no distinction.
Holding
A Holding is a location for a
Bibliographic Collection item.
A Holding can have many Items.
Image
An Image is a file that expresses an
exact digital
reproduction of the information stored on a physical digital object. It
is sometimes referred to as a disk image. The process of making an
image records the information on a physical digital object without
looking at the specific files stored on the object, and without making
any distinctions about the format of the files systems stored on the
media.
See also wikipedia
entry on Disk Images.
Item
An Item is an item or collection of items, which for the
purposes of Bibliographic cataloging is considered to be a single
conceptual unit. For example, an Item might be a collection of issues
of a Serial.
Although they may not be individually
identified within the
Catalogue or within the Holdings record or physically within the
Holdings location itself; within the Digital Preservation Workflow an
Item shall be only one "instance" of that Serial e.g. Vol. 10 Issue 3,
October 1987, etc. to better enable access and discovery to an item.
The Item may have parts such as a supplement, container or booklet.
Job
A Job within the Prometheus system is the process by which
one creates an annotated relationship between a Bibliographic
Record’s digital media Holding in the NLA Catalogue (Voyager) and
the digital preservation archive of that digital media within the
Prometheus digital repository for future access. This enables the user
to process material that has been assessed as qualifying for Digital
Preservation action to enable future access and allows the user to
process the material in a managed way that will ensure that sufficient
descriptive and technical documentation will be added or automatically
harvested to ensure on-going access to the material.
The Job consists of mostly tracking type
information and
Digital Preservation annotations to a specifically targeted a
Bibliographic Record or Accession item reference and it’s
associated Holding reference.
Metadata
Metadata is a classical Greek preposition
(μετ’ αλλων
εταιρων) and prefix
(μεταβασις) conveying
the following senses in English, depending upon the case of the
associated noun: among; along with; with; by means of; in the midst of;
after; behind.[1] In epistemology, the word means "about (its own
category)"; thus metadata is "data about the data". [courtesy of
Wikipedia]
It typically is descriptive of the
contents, location,
physical, technical attributes, type (e.g. text or image, map, audio or
video) and form of a resource or helps provide access to a resource.
Optical
Disc Case
These
are
high quality compact (5mm spine) clear, unbreakable, flexible
polypropylene cases are recommended for rehousing CDs / DVDs. Often
this will be replacing the brittle original 'Jewel' cases familiar to
Music CD users.
Part
A Job can have multiple Parts with each
Part corresponding to
one discrete component of an Holding Item. Each physical media item (CD-ROM,
Floppy Disk etc) associated within a
Holding will be come a
separate Part within a Job. Each Part should be uniquely named to match
its corresponding physical media’s name.
Process
A process is one step within a Workflow.
A process can
represent a different Work Flow in itself or could consist of a series
of sub-processes.
Stubs
The term ‘stub’ refers
to a media Part which is not fully
processed or uploaded using the application, but which the user wants
to
associate with an item so that all the Parts are known and recorded,
even if
not all can be uploaded to preservation storage.
A ‘stub’ can be created
or declared in a number of cases:
-
a
media Part is registered and processing
commences, but cannot be Completed due to error conditions, or similar.
A user
can then declare this Part a stub and allow the Job to be submitted for
ingest
(excluding the Part).
-
a
media Part is created, but there is no attempt
to process it – e.g. no suitable drive is available. However, a
user wants to
register that the media Part exists, so that it is known for future
reference.
A user can declare a stub at any time without attempting processing. An
error
state does not need to exist to allow a user to declare a stub.
Workflow:
A Workflow is a specific sequence of
processes (human or
otherwise) to achieve a specific purpose.
