XML: an interview with Peter Flynn

The developers of XML (Extensible Markup Language) intended it as a metalanguage - a language in which you can describe another language - for designing your own markup. Today, businesses see XML as a way to tag data so they can interchange it among applications, and groups are developing XML-based languages for exchanging data for business-tobusiness e-commerce, directory services, financial transactions, and wireless devices. As such, XML is becoming an important tool in application integration. Peter Flynn was a key voice in developing the standard and remains an active observer of how XML is finding its place in the world.
