=== File ===
A file is a [[#Third class data object|third class]] [[#Data object|data object]].  This is because it is a [[#Sub-object|sub-object]] of a [[#Document|document]] data object, which in turn is a sub-object of an [[#EPrint|eprint]] data object.  A file data object store metadata relevant to the file such as its filename, size, MIME type and modified time and a hash (by default MD5) to maintain the integrity of the file.  Typically uploading a document to an eprint will only create a single data object but it is possible to add additional files to a document after it is uploaded.

File data objects are also used to capture XML [[#Revision file|revision files]] created for recording [[#EPrint revision|eprint revisions]].

=== First class data object ===
[[#Data object|Data objects]] in [[#EPrints repository software|EPrints repository software]] take a particular order.  First class data objects are those that are not a sub-objects of other data objects, such as:
* [[#EPrint|eprint]]
* [[#User|user]]
Other data object may be described as either [[#Second class data object|second class]] or [[#Third class data object|third class]].  Usually a data object is only described as "first class" if it contains sub-objects.  Technically, [[#Subject|subject]] is a first class data object but as it contains no sub-objects, it in unnecessary to make the distinction.

=== Flavour ===
From version 3.4 of [[#EPrints repository software|EPrints repository software]] different flavours have been introduced.  EPrints was originally designed as a [[#Repository|repository]] for research publications but over the years it has been repurposed for different tasks, which has led to the codebase getting a little messy.  So in [https://www.eprints.org/uk/index.php/eprints-3.4/ EPrints 3.4] a separate sub-directory structure was created to store code and configuration that makes EPrints suitable for a particular task, (i.e. a flavour).  There are three main flavours but most development has continued to focus on research publication:
# [[#Publication flavour|Publication flavour]] - For research publications.  Provided in ''[[flavours/pub_lib/]]''.
# [[#Data flavour|Data flavour]] - For research data.  Provided in ''flavours/data_lib/''.
# [[#Education flavour|Education flavour]] - For Open Education, i.e. teaching materials.  Provided in ''flavours/edu_lib/''.
As well as flavours in EPrints 3.4, there are also ''[[#Ingredient|ingredients]]'', which provide additional functionality, similar to a [[#Bazaar plugin|Bazaar plugin]] / [[#EPM|EPM]].  Any EPrints flavour has an ''inc'' file found in its top-level directory (e.g. ''flavours/pub_lib/inc'').  This tells the flavour which paths to include.  By default, this would include the flavour itself.  It may also contain various ingredients and potentially [[#Site lib|site_lib]] if the repository has multiple [[#Archive|archives]], which require the same bespoke functionality.  However, it is better if this bespoke functionality can be converted into ingredients to separate out discrete parts of functionality.
