Editing EPrints Glossary (section)

== E ==
=== Editor ===
On [[#EPrints repository software|EPrints repository software]] '''editor''' could refer to one of two different things:
# A type of EPrints [[#User|user]] that has permissions to access some or all [[#Publication record|publication records]] in the [[#Review buffer|review buffer]] to make amendments and either push the item to the [[#Live archive|live archive]] or return it to the [[#User workarea|user's workarea]].
# A [[#Metadata field|metadata field]] in the [[#EPrint|eprint]] [[#Data object|data object]] to record editors of the publication, e.g. the editors for a book.  Like [[#Creator|creator]], by default this field has family name, given name and ID (i.e. email address) sub-fields.

=== Editorial rights restriction ===
Same as [[#User review scope|user review scope]].

=== Education flavour ===
This is a [[#Flavour|flavour]] of [[#EPrints repository software|EPrints repository software]] version 3.4+. It is intended to produce repositories for open education.  I.e. for hosting files such as presentation slides, videos of lectures/seminars, instructions for learning tasks, in-class quizzes, etc.

=== Embargo ===
[[#Document|Documents]] added to an [[#EPrint|eprint]] can have their access restricted.  Sometimes, this access need only be restricted for a set amount of time.  These documents can be embargoed until a set embargo date.  These can then be lifted of this date using the [[API:bin/lift_embargos|bin/lift_embargos]] script.  More recently embargoes allow a reason to be chosen from a predetermined set of options provided by the ''embargo_reason'' [[#Named set|named set]].

=== EPM ===
EPM (EPrints Package Manager) is a package of functionality, sometimes referred to as a ''Bazaar plugin'', which can be installed in an automated fashion, typically from the [[#Bazaar|Bazaar]].  It can sometimes refer to the pages for managing the installing of these packages, (e.g. the [[Admin/System Tools/EPrints Bazaar|EPrints Bazaar]] page available through the [[Admin]] web interface).

=== EPrint ===
An [[EPrint Object|eprint]] is a [[#First class data object|first class]] [[#Data object|data object]] in [[#EPrints repository software|EPrints repository software]]. These are often referred to as ''[[#Item|items]]'' or ''[[#Publication record|publication records]]'' as they are generally intended hold [[#Metadata|metadata]] about a publication of some kind.

=== EPrint control page ===
Same as an [[#EPrint view page|eprint view page]].

=== EPrint history ===
This is the history of an [[#EPrint|eprint]] shown in the [[#History tab|history tab]] of the eprint's [[#View page|view page]].  It is generated from the [[#EPrint revision|eprint revision]] [[#Revision file|files]] generated each time an eprint is modified.  These are compared to display differences between revisions to track the eprint's history for administration purposes.

=== EPrint locking ===
Whilst a [[#User|user]] is editing an [[#EPrint|eprint]] it is best that another user does not try to edit it as well.  When an eprint is locked, even permitted users will not be able to edit that record, unless they remove the edit lock.  Locks are automatically released when a user saves or cancels editing an eprint or (by default) 1 hour after the user started editing the eprint.

=== EPrint revision ===
An EPrint revision is a numbered version of the [[#EPrint|eprint's]] [[#Metadata|metadata]] stored in the ''rev_number'' [[#Metadata field|metadata field]].  Revisions of eprints metadata are exported as XML [[#Revision file|revision files]] and stored under the [[#Documents directory|documents directory]] of the [[#Archive|archive]].

=== EPrint status ===
The status of an [[#EPrint|eprint]] represent the stage it is in the depositing lifecycle.  By default in [[#EPrints repository software|EPrints repository software]] this can be one of four states:
# [[#User workarea|User workarea]] - The eprint is still being edited by the [[#Depositing user|depositing user]] as there is still metadata they need to add or change.
# [[#Review buffer|Review buffer]] - The eprint has been submitted for review by an [[#Editor|editor]] for the [[#Archive|archive]].
# [[#Live archive|Live archive]] - The eprint has been reviewed by the editor and they have deposited it into the live archive for public access.
# [[#Retired|Retired]] - The eprint has been removed from the live archive as it is no longer appropriate for it to have public access.

=== EPrint type ===
This is the type of publication the [[#EPrint|eprint]] represents.  The available types for a [[#Repository|repository]] are specified in a [[#Named set|named sets]] file. ( ''lib/namedsets/eprint'' or ''flavours/pub_lib/namedsets/eprint'') or can be copied to the [[#Archive|archive]]'s [[archives/ARCHIVEID/cfg/namedsets/]] directory to add extra types for a specific archive.  By default [[#EPrints repository software|EPrints]]' [[#Publication flavour|publication flavour]] has the following type options:
 article
 book_section
 monograph
 conference_item
 book
 thesis
 patent
 artefact
 exhibition
 composition
 performance
 image
 video
 audio
 dataset
 experiment
 teaching_resource
 other
Type is by default presented on the first [[#Workflow stage|stage]] of the [[#EPrint workflow|EPrint workflow]], as the option chosen will affect the fields that can/need to be completed in later stages.

=== EPrint URI ===
The URI for an [[#EPrint|eprint]] is its globally unique identifier.  In a form like:
 http://example.eprints.org/id/eprint/1234
Technically, a URI only need be an identifier and therefore not return the resource itself.  However, in the case of [[#EPrints repository software|EPrints repository software]], this will return the resource.  Prior to EPrints 3.4, this would be by redirecting to the [[#EPrint URL|eprint URL]] but since then the [[#Publication flavour|publication flavour]] uses the same string for the eprints URL and URI with the old style URL redirecting the longer URI format URL.

=== EPrint URL ===
The URL of an [[#EPrint|eprint]] is the location it can be found at on the World Wide Web.  Historically with [[#EPrints repository software|EPrints repository software] it has taken a form like:
 http://example.eprints.org/1234/
However, since EPrints 3.4, it has been possible to configure the URL to take a long format like that of the [[#EPrint URI|eprint URI]]:
 http://example.eprints.org/id/eprint/1234
By using the following setting (typically in the [[#Archive|archive]]'s ''cfg/cfg.d/[[20_baseurls.pl]]''): 
 $c->{use_long_url_format] = 1;
By making this change the old style URL will still work but will redirect to the new format.  The reason for the change was to make it more apparent that the URL represented a publication within EPrints repository.  Web crawlers and bots often record links (i.e. URLs) they find on web pages but they don't actually access them.  In particular [https://scholar.google.com Google Scholar] would disregard these URLs without checking them, as there was nothing from the URL to indicate they represented a publication.  By adding ''/id/eprint/'' into the URL it makes it the URL distinct from other common URLs of the form ''<nowiki>http://HOSTNAME/ID</nowiki>'', which are mostly not URLs for EPrints [[#Abstract page|abstract pages]].

=== EPrint view page ===
The view page for an [[#EPrint|eprint]] is a multi-tabbed management page for that particular item.  It can typically be reached by clicking on the ''View Item'' link towards the bottom of an eprint's [[#Abstract page|abstract page]].  This page will tend to have the following tabs:
# [[#Preview tab|Preview]] - What will the abstract page look like when the eprint is moved to the [[#Live archive|live archive]].
# [[#Details tab|Details]] - The values for all the [[#Metadata field|metadata fields]] for the eprint.
# [[#Actions tab|Actions]] - All the actions that can be carried out against the eprint.
# [[#History tab|History]] - The [[#EPrint revision|revision]] history of the eprint.
# [[#Issues tab|Issues]] - The [[#Issue|issues]] detected for this eprint, if any.

=== EPrint workflow ===
This is the [[#Workflow|workflow]] that pertains specifically to the [[EPrint Object|eprint data object]].

=== EPrints repository software ===
Often shortened to just '''EPrints''' but not to be confused with multiple eprint data objects, (i.e. eprints). The actual software that can be used to create Open Access repositories and available as Open Source from [https://github.com/eprints/eprints3.4 GitHub].

=== EPrints path ===
The path on your operating system under which EPrints repository software is installed.  Guides on this wiki often use the placeholder <tt>EPRINTS_PATH</tt> to represent this.  Typically EPrints path will either be '''/opt/eprints3/''' or '''/usr/share/eprints/''' depending on how EPrints repository software was installed.

=== EPrints release ===
A release of the [[#EPrints repository software|EPrints repository software]].

=== EPrints version ===
Same as [[#EPrints release|EPrints release]] but with specific reference to a version number.

=== EPrints XML ===
[[#EPrints repository software|EPrints repository software]] has its own XML schema for defining how [[#Data object|data objects]] should be described.  This schema can be found at the equivalent URL to:
 http://example.eprints.org/cgi/schema

=== Event plugin ===
A type of [[#Plugin|plugin]] that generates [[#Indexer task|Indexer tasks]] to get the [[#Indexer|indexer]] to perform some asynchronous and potential long-running task.

=== Event queue ===
The event queue contains all generated and yet to be successfully completed [[#Indexer task|indexer tasks]].  It can be accessed through the [[#Admin menu|admin menu]]'s [[Admin/System Tools|System tools]] tab using the [[Admin/System Tools/Status|Status]] button and then clicking on the number next to the '''Background Task Queue'''.  There is also the [[Event Queue Object]], which is a [[#Data object|data object]] to represent an individual indexer task.

=== Export plugin ===
This is a [[#Plugin|plugin]] designed to provide a formatted export of a [[#Data object|data object]]'s [[#Metadata|metadata]], typically for an [[#EPrint|eprint]].  By default, [[#EPrints repository software|EPrints repository software]] has export plugins for many different formats, which can be found in the ''[[perl_lib/EPrints/Plugin/Export/]]'' and ''[[flavours/pub_lib/plugins/EPrints/Plugin/Export/]]'' directories.  Bespoke export plugins can also be added to the archive's ''cfg/plugins/EPrints/Plugin/Export/'' directory or may be installed from the [[#Bazaar|Bazaar]] into the ''lib/plugins/EPrints/Plugin/Export/'' directory.
