Ari Nordström is an SGML/XML consultant at AerotechTelub Information & Media AB. He's one of the designers of Ericsson'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 help move the Volvo Car Corporation authoring environment from SGML to XML, including the creation and redesign of a number of DTDs.

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.
