Blue Angel Technologies Tuesday announced MetaDoor InterChange, an XML authoring tool that generates XML from desktop applications like Microsoft Word and Excel. MetaDoor InterChange separates the data entry process from the record structure so that data entry forms can hide XML from users. MetaDoor InterChange is the latest addition to Blue Angel’s suite of XML enabled software solutions. MetaDoor InterChange will be available January 15, 1999 and is priced at $49 per seat.
