1.1. Glossary

This section provides a number of terms that you will encounter when implementing eXo Platform.


A web-based environment which is used for aggregating and personalizing information via specific applications with an interactive and consistent look and feel. Users and administrators are able to integrate information, people and processes via a web-based user interface.


An applicative component pluggable to a site through which users can access some specific information, including supports, updates, or mini-applications. The portlet produces fragments of a markup code that are aggregated into a page. Typically, a page is displayed as a non-overlapping portlet windows collection, where each portlet window displays a portlet. Content generated by a portlet can be customized, depending on the configuration set by each user. Portlets can be divided into two following types:


A super-user is a special user who has full privileges and used for the administration. In eXo Platform, this account is configured with Root, Root, root@localhost and its memberships are member:/organization/management/executive-board, *:/platform/administrators, *:/platform/users, *:/platform/web-contributors, *:/organization/employees. A super-user has all permissions on all features of eXo Platform.


A set of menus (sometimes so-called node tree) that contains hyperlinks to other parts of a site. The default navigation menus in eXo Platform are located in the top navigation bar:


A collaboration workspace where you can share documents, tasks, events, wikis and more. A space can be open or closed, private or public and space administrators can manage members and applications that are available.


A bond among people in a network. By connecting to other people, you will be able you to track their activities through the activity stream.


An activity is published on the Activity Stream and allows you to follow what your connections are sharing, such as links to documents or just moods. An activity can be made out of different parts:


A mini web application which is run on a platform and can be integrated and customized in the website. You can add these gadgets to your dashboards by yourself.


eXo Platform offers two access modes by default:


Permission settings control actions of a user within the site and are set by the administrators. See Managing permissions for more details.


A locus where content or digital data are maintained. Users can access without traveling across a network.


A shortcut to a specific location in the content repository that enables administrators to limit visibility of each workspace for groups of users. It is also a simple way to hide the complexity of the content storage by showing only the structure that is helpful for business users.

In details, a drive consists of:


An abstract unit used to build linked data structures, such as linked lists and trees, and computer-based representation of graphs. Nodes contain data and/or links to another nodes. Links between nodes are often implemented by pointers or references.

Also, a node can be defined as a logical placeholder for data. It is a memory block which contains some data units, and optionally a reference to some other data. By linking one node with other interlinked nodes, very large and complex data structure can be formed.


This term stands for Web-based Distributed Authoring and Versioning. In eXo Platform, it is used as a mean to access the content repository directly from the Sites Explorer.


A special file which contains a reference to a document or a folder. By using symlinks, you can easily access specific nodes (target) to which symlinks point. In Documents, a symlink has a small chain symbol next to its icon.
