controlling access to stock content and functions. These permissions include viewing,
creating, editing or administering of

permissions. You can add roles for classifying users,
assign users to roles and
assign permissions for the publication content to
those roles. For a simple setup, allow anonymous users access to view organism content and
allow the site administrator all other permissions.

this module allows a user to search, by remote connection , the PubMEd database for articles

Publication titles and when one of the key words is matched in a title, the recognized article will
be saved to the database.
- Choose a Controlled Vocabulary:The controlled vocabulary list is a set of terms
- Set Search Key Words:The search keywords, are the user entered key terms, in which
the publications in the PubMed database can be recognized by. The user may enter any number
of search terms, as by adding more search terms, the search will limit the results to those
in which all of the search terms appear in the publication title.
- Set a time search interval:The search term interval represents a pre-set ammount
of time for the search. The time search interval must be entered in minutes. This allows
the module to automatically search the PubMed database in a predetermined time interval.
- Creating a Publication:';

it is neccessary to enter the requried fields in the form. These are marked with an astrix and

in these entries. The author field, requires a given/surname/suffix to be entered. To add the
author to the publication, the add author button is to be pushed. The user is able to add as
