In 1998, Songline Studios, an affiliate of O'Reilly and Associates, joined Seybold Publications to create XML.com (http://www.xml.com), an advertisement-driven commercial site devoted to reporting on the state of the XML business. XML.com's editorial mission is to report fairly on events happening in XML, and they do an exceptional job in covering the state of standards developments and vendor implementations of XML.
XML.com is not simply a site that publishes technical information or press reports. Instead, the staff and contract writers contribute articles that cover conflicts in the industry or implementation-specific details where incompatibilities are likely to occur. For example, they reviewed how several popular parsers fared using the XML Conformance Test Suite, a technical compatibility test designed by the Organization for the Advancement of Structured Information Systems (OASIS) and the U.S. National Institute of Standards and Technology (NIST). The test is designed to check a parser's adherence to the published W3C XML specification.
