Data Object representing a single EPrint record.

It belongs to the "eprint" dataset.

In the API it is represented as an instance of EPrints::DataObj::EPrint.

Metadata Fields

Field Name	Type	Description
eprintid	int field	The ID number of this EPrint Object (unique within a single repository)
rev_number	int field	The metadata revision number. Increased by 1 every time this record is modified.
documents	multiple subobject field	zero or more Document Objects attached to this EPrint. In effect these are sub-objects.
eprint_status	set field	the status of this eprint.
userid	itemref field	the userid of the User Object which first created this item. This is the user that can see the eprint in their userarea.
dir	text field	the path that the documents for this eprint are stored, relative to Archives/ARCHIVEID/documents/
datestamp	time field	the time the eprint first appeared in the live archive. Is only ever set once.
lastmod	time field	the time this eprint was last modified
status_changed	time field	the time the eprint_status field was last modified (ie. when it was last moved between datasets)
type	namedset field eprint	the type of this eprint (eg. article, etc).
succeeds	itemref field	if this eprint is a new version (not revision) of an existing eprint record, this is the id of the record it replaces.
commentary	itemref field	if this eprint is a commentary on an existing eprint record this is the id of the record it comments upon.
replacedby	itemref field	if this eprint has a newer version then this is the id of the newer version (opposite of "succeeds")
metadata_visibility	set field	if set to no_search then this record does not appear in search results. Used for older versions of a thing where all versions must exist but it's only useful to discover the newest one.
contact_email	email field	an email address for correspondance about this eprint. Used to request documents which are not online, or not public.
fileinfo	longtext field	used to cache the icon urls and links for the documents, so they can be easily used in citations.
latitude	float field
longitude	float field	these store the position on earth which this eprint relates to, if any. This could be where it was presented, where the author lives, or the location may be the subject of the eprint such as a city or an archaelogical dig. The exact use depends on the repository.
****	Repository-specific fields for the EPrint Object are defined in eprint_fields.pl - these are in addition to the fields listed here, which are always in EPrints for any repository.
