HTTP is a well studied cross-platform protocol and there are mature implementations freely available.

So there are *plenty* of similar implementations available against which to judge if any given feature might be appropriate for a lightweight standard.

Available in multiple complete implementations by competing vendors, or as a complete implementation equally available to all parties.

Web developers will adopt the new features when there are mature implementations available across enough mainstream browsers.

The following represents our best attempt at comparison, based on review of the available implementations and associated documentation as of January 2003.

There are several implementations available of SRM for color image segmentation:

There are two commonly available implementations of network-based storage virtualization, appliance-based and switch-based.

It is unclear whether available implementations of Trimension scale before or after tweening.

Many references, including links to available implementations.

G. Brinkmann also provided a freely available implementation, called fullgen.
