Editing EPrints Glossary (section)

=== Citation ===
In [[#EPrints repository software|EPrints repository software]] a citation means something slightly different from what it means in research publication.  For the former it refers to a text string describing a publication, which may more commonly described in research publications as a ''reference''.  

EPrints repository software has citation style files, which describe how to generate the text string, not just for [[#EPrint|eprints]] but also other [[#Data object|data objects]], each of which can have different citation style files for different purposes.  These files can be found under [[lib/citations/]], [[flavours/pub_lib/citations/]] and the [[#Archive|archive]]'s ''cfg/citations/'' directory.  

See here for more information about the [[Citation Format|citation formats]] and a training video about [[Training_Video:Citation_Styles|citation styles]].

=== Compound metadata field ===
A [[Compound field|Compound metadata field]] is a type of [[#Metadata field|metadata field]] that is made up of several sub-fields.  A good example of this is the ''Relationships'' field for an [[#EPrint|eprint]] [[#Data object|data object]].  This has two sub-fields one for the type or relation and the second for the actual thing (represented by a URI), that the eprint is related.

=== Core codebase ===
The core codebase refers to the main code directories of the [[#EPrints repository software|EPrints repository software]].  In some contexts this refers to all directories except the archives directory which contains the configuration for individual [[#Archive|archives]].  In other contexts this refers to just the following directories (i.e. excludes [[#Flavour|flavours]], [[#Ingredient|ingredients]] and [[#Site lib|site_lib]], as well as non-code directories).
* [[bin/]]
* [[cgi/]]
* [[lib/]]
* [[perl_lib/]]
* [[tools/]]

=== Core field ===
Same as a [[#System field|system field]].

=== Contact page ===
This is a [[#Static page|static page]] that is accessible on an [[#Archive|archive]] at the equivalent URL to the following:
 https://example.eprints.org/contact.html
This page is intended to provided contact information, so to those accessing the archive can contact those responsible for it to report problems or ask questions.

This page can be found at ''EPRINTS_PATH/lib/lang/en/static/contact.xpage'' but should be copied to the archive's ''cfg/lang/en/static/'' directory for [[How_to_modify_static_pages|editing]].  The email address displayed on this page comes from the <tt>$c->{adminemail}</tt> in [[adminemail.pl]].

=== Contributor ===
Sometimes an [[#EPrint|eprint]] has a contributor who could not usefully be described as a [[#Creator|creator]] or [[#Editor|editor]].  The contributor [[#Metadata field|metadata field]] is intended to allow these people to be associated with the eprint.  As well as being able to add the contributor's family and given name, the type of contributor can be specified.  This list of types is defined in ''EPRINTS_PATH/lib/namedsets/contributor_type''.  If additional types are needed, then this file should be copied to the [[#Archive|archive]]'s ''cfg/namedsets/'' directory for editing.

=== Creator ===
Creator (or creators) is a [[#Metadata field|metadata field]] for an [[#EPrint|eprint]].  Sometimes this is alternatively referred to as author but creator is a more generic term better suited to audio-visual/artistic as well as more traditional research publication items.

A creator typically has several separate sub-fields:
* Given name (a.k.a. first name)
* Family name (a.k.a. surname)
* ID (typically email address)

=== CRUD API ===
CRUD API (Create, Read, Update Delete Application Programming Interface) refers to a programmatic interface used for the management of [[#Data object|data objects]].  It is often also referred to as the [[#REST API|REST API]] as when it is called over HTTP it meets the requirements of a REST API.
