I'm the founder and proprietor of Black Mesa Technologies, a consulting operation focused on helping solve IT problems for memory institutions (libraries, publishers, archives, museums), scholarly and scientific projects (e.g. editions, corpus development, and textbase projects), and other people interested in making data useful for the long term.

Before founding Black Mesa, I was a member of the technical staff at W3C and co-edited the XML 1.0 and XML Schema 1.1 specifications; before that, I served as co-editor of the Text Encoding Initiative Guidelines.
