For now, there is no one universally accepted format for web fonts.

This may change in Reykjavik this september, as the WebFonts working group of the W3C (World Wide Web Consortium) will be meeting during ATypI to finalize the development of the conformance test suite and prepare a draft implementation report on Web Open Font Format (WOFF).

The meeting is hosted by ATypI (Association Typographique Internationale); and it will take place a day before this year’s ATypI conference starts.
