Standards Compliance

The Umm el-Jimal Project and its partners are committed to developing according to evolving web standards. While the Web changes quickly, we also strive to adhere to open source code and software whenever possible. As such, our website relies on three bedrock technologies which are free to all, browser and device independent, and available across the globe. Nevertheless, by necessity we do also use code based on three proprietary applications: Apple Quicktime VR and Adobe Flash for the Virtual Tour, as well as Microsoft's Seadragon (Deep Zoom) project for the Timeline and NE Jordan interactive maps.

For technical details and troubleshooting, see the Help page.


The Umm el-Jimal Project uses HTML5 exclusively, which is the current development model for hypertext markup language—the core of web content. While version 5 is not yet an official standard, it has been adopted by the W3C as a provisional standard and has quickly superceded other versions.


The website's graphic design and structure are created using CSS3, or cascading style sheets version 3, which is part of the HTML5 standard.


Most of this website's interactive elements are built with Javascript, a widely-used programming language supported by all modern browsers.


Support for mobile devices is under development. Some mobile-friendly features, such as responsive pages, non-Flash video formats, swipe-ready multimedia, and touch-friendly buttons have already been implemented. Work is ongoing to add additional support for media-heavy elements such as the site's slideshow galleries, interactive walls, and zoomable maps.


The current site is version 3.0.


This website uses a number of enhancements designed to make access easier for users with additional needs:

Text Resizing

Browser-based text resizing will not break the site's structure or visual style.

No Image Mode

Disabling images will not affect the site's design, navigation, or content.

Color & Contrast

The site maintains visibility and contrast across a variety of colorblind conditions.

Speech Support

Content is compatible with common text-to-speech software packages.
