Ari Nordström is an SGML/XML consultant at AerotechTelub Information & Media AB. He's one of the designers of Ericsson's and Volvo's standard DTDs, as well as the designer of a number of DTDs and authoring systems for other companies. His most recent assignment is to design the DTD and some of the filters required for the exchange of information between Ford companies such as Volvo, Mazda, and Ford.

Ari Nordström spends some of his spare time projecting films at the Draken Cinema in Göteborg, Sweden, which should explain why he wants to automate cinemas using XML.
