About and Copyright pages #

This page is for administrators who need to know which Exponential they run, what it is made of and under which licenses, and for extension maintainers who want their extension to show up correctly. Info > About and Info > Copyright in the admin answer those questions. Between 27 and 30 September 2026 they were rebuilt as proper pages of the admin design and made trustworthy: every extension is listed with a description, license and website, whatever its metadata looks like.

Read the About page #

Open Info > About (/ezinfo/about). You see:

• a summary with the version, the number of extensions and of third-party components, and links to the sections;
• What is Exponential, the license in a scrollable block, and the copyright notice;
• Third-party software as a table: software, version, license and the extension that includes it;
• Extensions as a table you can sort by loading order, name, identifier, version and license. Under each name: description, copyright, author and included software, with a link to its website.

The tables become cards when the content column is narrow, so neither page scrolls sideways on a phone or at 200 percent zoom. The styles are in stylesheets/ezinfo.css, loaded by these two pages only. Every text is translatable (English, eng-US, and German are complete).

Read the Copyright page #

Open Info > Copyright (/ezinfo/copyright). It shows the copyright, license, warranty and original authors as sections in the interface language, with the notice as distributed (English) below. It states Exponential's copyright and the GNU General Public License version 2 (or any later version), the warranty disclaimer, and keeps the attribution to the original developers that the license requires. It no longer offers a business use license Exponential cannot grant.

Designs can present the notice themselves: the page renders through the ezinfo/copyright template, with the plain notice as the fallback. The about and copyright views also hand designs table rows and the parts of the notice.

Make your extension show up well #

State Name, Version, Copyright, License and Info_url in ezinfo.php, and the same in extension.xml. The release rule is that the number inside the extension equals the release number. See Extension metadata.

The RAD extension wizard names the class of a generated ezinfo.php after the extension (<extension>Info), as the kernel expects, so extensions with an underscore in their name show their details.

How an extension's row is filled #

eZExtension::extensionInfo() collects the facts in this order, and each source fills only the fields the earlier ones did not give:

1. <metadata> of extension.xml, and ezinfo.php
2. the top level of extension.xml (summary, license, version, copyright), for an extension.xml without <metadata>
3. composer.json: description, license, version, support source or homepage, authors
4. the https address of the git origin in .git/config (read, never run)

An extension that declares no name, or only its directory name, is listed under the name its description starts with (for example "Exponential Layouts - ..." gives "Exponential Layouts"), otherwise under its directory name as before. A broken ezinfo.php no longer breaks the about page.

The kernel-shipped extensions ezjscore, ezoe and ezformtoken now state the Exponential version they ship with, name their license in full ("GNU General Public License v2.0 (or any later version)") and link to their repositories. About two dozen extensions released new versions in the same sweep, so that every row of the about page has a version, license and website.
