EPrints 2.0 Documentation - EPrints Structure and Terms |
This is a definition of some terms used in the eprints documentation and comments. Many of these are ``objects'' within the code and the perl module which handle them is listed.
EPrints::Archive
An archive is a eprints archive with it's own website configuration and data. One install of the eprints software can run serveral seperate archives. Sharing code but with totally different configurations.
EPrints::Session
A session is created every time a cgi script or a bin script is executed, and terminated afterwards.
EPrints::EPrint
An eprint is a record in the system which has one or more documents and some metadata. Usually, more than one document is to provide the same information in multiple formats, although this is not compulsary.
EPrints::Document
A document is a single format of an eprint, eg. HTML, PDF, PS etc. It can contain more than one file, for example HTML may contain more than one html page + image files. The actual files are stored in the filesystem.
EPrints::User
A user registered with the system. (NOT necesarily the author of the eprints they deposit).
EPrints::Subject
A subject has an id and a list of who it's parents are. There is a build in subject with the id ``ROOT'' to act as the top level. A subject can have more than one parent to allow you to create a rich lattice, rather than just a tree, but loops are not allowed.
EPrints::DataObj
The ``super class'' of subjects, users, eprints and documents. In the very core of the system these are all treated identically and much of the configuration and methods of these classes of ``thing'' are identical. We use the term item to speak about the general case.
EPrints::DataSet
A dataset is a collection of items of the same type. It can be searched.
Core datasets are:
DATASET ID | TYPE | COMMENT | | inbox | eprint | Eprints which users are still working on. buffer | eprint | Eprints submitted for editorial approval. archive | eprint | Eprints live in the archive. deletion | eprint | Eprints which have been deleted from the archive. user | user | Users registered. subject | subject | The subject tree or lattice. document | document | The documents belonging to ALL | | eprints in the system.
EPrints::Database
The connection to the MySQL back end. datasets are stored in the MySQL system, but you do not have to address it directly.
EPrints::MetaField
A single field in a dataset. Each dataset has a few ``system'' fields which eprints uses to manage the system and then any number of archive specific fields which you may configure.
