-
Multiple languages Updated
One Exponential installation can hold its content in many languages. Each content object can have a translation in every language of the installation, and each siteaccess decides which languages it shows and in which ord…
-
Node visibility Updated
Hiding a node takes it, and everything below it, off the public site without removing anything. Editors still see and edit hidden content in the administration, and revealing the node brings the whole subtree back exactl…
-
Object relations Updated
Objects can point to other objects. A related object is not a child in the tree: it can be anywhere, and one object can be related to many others. Relations let an article show its author's profile, a product its accesso…
-
Sections Updated
A section is a named group of objects. Sections are used for three things: limiting permissions (anonymous visitors may read the section Standard), choosing templates (articles in the section Members get another layout)…

The content node Updated
A node, also called a location, is the place of a content object in the content tree . The object holds the content; the node says where it sits, who its parent and children are, and at which address it is shown. Templat…

The content object Updated
A content object is one piece of content: an article, a folder, an image, a user account. It is an instance of a content class and holds a value for each of the class's attributes. Objects are never edited in place: ever…

Top level nodes Updated
Below the root of the content tree every installation has the same five top level nodes. Each one is the start of a part of the administration interface and of a section , and settings refer to them by node ID. Node ID N…

URL storage Updated
Every external address used in content, whether in a URL attribute or as a link in rich text, is stored once in a shared table of links (ezurl). The content itself holds only a reference to the row. This lets administrat…
-
Design combinations Updated
A siteaccess rarely uses one design on its own. It names a main design, adds fallback designs, and every active extension can bring files for any of them. Exponential combines all of these into one ordered list of direct…

Cluster Configuration Settings Updated
A DFS cluster is configured in two places: file.ini for Exponential itself, and the CLUSTER_* constants of config.php for index_cluster.php, the script that serves clustered files to browsers. Both must name the same dat…

Cluster File Handlers Updated
A cluster file handler is the class through which Exponential stores, reads, renames and removes the files of var/: images, binary files and the content caches. The handler is set in file.ini [ClusteringSettings] FileHan…

Maintenance Updated
A DFS cluster does not remove files at once. When content is removed, or a cache expires, the file is only marked as expired in the metadata table, so that other servers still reading it are not disturbed. Expired files…
