New web development tools being built with XML are emerging. Their
developers hope to capture the success of RSS, which has helped simplify
syndication and has led to the emergence of news
aggregators and RSS Feeds. Here are a couple new XML-built
tools that have come to our attention. OpenSearch has been
announced by Amazon.com's on their A9.com search engine. Amazon says OpenSearch is a collection of technologies, all built on top of popular open standards, to allow content providers to publish their search results in a format suitable for syndication. A9.com has already put the technology to work with its search engine. Search providers can submit their search technologies to A9.com (an OpenSearch Aggreator) using OpenSearch RSS and OpenSearch Description Documents. You can see websites that have already added OpenSearch RSS here. Another XML-based technology, called ROR, defines itself as a simple flexible XML format for describing the resources of a resource (e.g. objects of a website, entries of a blog or feed, a list of things, a group of people, a directory, etc). Here
is an example of what ROR can do. There will continue to be more and more XML
technologies released over the next couple years.
