PediaView.com provides a lightweight wrapper for content from the open source Wikipedia™. We think we've put together one of the easiest and most secure ways to make use of Wikipedia content on your own website, and we're now putting the finishing touches on the open source version of our Wikipedia™ script, as well as completing our final beta tests of a spiffed-up script for using Wikipedia™ that includes a built-in searching facility and fully templated page delivery.
So if you'd like to use Wikipedia™ content on your own site, just as we are here, stay tuned and check back regularly for updates!
