Senior🎓
Top SchoolC. Sperberg-McQueen is the founder and principal consultant of Black Mesa Technologies, specializing in XML, XSD, and XSLT for vocabulary development, validation, and long-term preservation of cultural heritage data. A pioneer in descriptive markup since 1988, he co-edited the first XML specification, led the XSD 1.1 editorial work, and chaired W3C XML coordination efforts during a decade at the W3C. His background as editor-in-chief of the Text Encoding Initiative and academic training (Ph.D. in comparative literature) give him a rare blend of humanistic scholarship and deep standards engineering. He focuses on practical schema design and transformation workflows that make data durable and interoperable, and is a frequent conference speaker and educator. Based in New Mexico, he continues active research into the theory and practice of markup while consulting on accessibility and preservation projects. An often-cited early advocate for SGML/XML on the Web, he combines historical perspective with hands-on tooling and standards stewardship.
