Version 2.0 is a legacy release, and these documents are no longer being maintained.

Technical Requirements

Server-side requirements (for installation, hosting, etc.)

Details for the hardware and server environment, and the software dependencies (both required and recommended) have been documented in our Administator Manual. For further details, see: Requirements.

Client-side requirements (for end users)

AtoM has been designed with minimal assumptions about the technology available to users and contributors. All that is required is access to the internet and a web browser (any web browser will do, though use of a modern web browser is strongly encouraged). AtoM does, however, rely on “client-side” JavaScript to achieve certain effects when displaying content:

  • on edit pages, fields are grouped into information areas that are “collapsible” (i.e., fields can be displayed or hidden)
  • Some drop-down menus are collapsible (i.e. options in the list can be expanded to display more options or collapsed to hide them)

Older browsers that do not support JavaScript will not be able to view these effects. They are still able to access AtoM unimpaired; it just won’t look as nice. It is recommended, therefore, that users employ modern web browsers that support JavaScript (such as Firefox, Chrome, Opera, or Safari.)

Internet Explorer 8 and AtoM 2.0

With the release of 2.0, AtoM will no longer support Internet Explorer (IE) 8 or earlier versions. If possible, please upgrade your browser to IE9 or higher, or use a supported browser such as Firefox, Chrome, Opera, or Safari.

Alternately, if you are unable to update your browser, we recommend installing the Google Chrome Frame for Internet Explorer:

“Google Chrome Frame is an open source browser plug-in. Users who have the plug-in installed have access to Google Chrome’s open web technologies and speedy JavaScript engine when they open pages in the browser.

Google Chrome Frame seamlessly enhances your browsing experience in Internet Explorer. It displays Google Chrome Frame enabled sites using Google Chrome’s rendering technology, giving you access to the latest HTML5 features as well as Google Chrome’s performance and security features without in any way interrupting your usual browser usage.”

Google has announced that it will no longer be providing support for the Chrome Frame after January 2014

To Install Chrome Frame:

  1. Open Internet Explorer (version 7, 8, or 9)
  2. Navigate to:
  3. Follow the download and installation instructions
  • You will first have to agree to Google’s Terms and Conditions of Use:
  1. The installation should only take a moment, and you will not see any noticeable change in the browser
  1. Remember, if you need to manage or uninstall this add-on, you can do so in Internet Explorer by going to Tools > Manage Add-ons and selecting the Chrome Frame add-on from the list.
