Embedded OpenType (.EOT) Font Format Submission Request to W3C

We, W3C Member:
  1. Microsoft Corp.
hereby submit to the Consortium the following specification, comprising the following documents attached hereto:
  1. Embedded OpenType (.EOT) Font Format
  2. MicroType? Express Font Format Specification Version 1.2

Monotype Imaging hereby contributes "MicroType? Express Font Format Specification Version 1.2" to this Submission; see the relevant IPR statements below.

Abstract

The Embedded Font Format (EOT) was developed by Microsoft to enable OpenType fonts to be linked to web pages for download to render the web page with the font the author desired. This appendix specifies the format of the .EOT file so that User Agents can download, extract and temporarily install fonts of the .EOT file suffix that are included in the @font-face definition of a CSS style sheet. Example pages can be found at the Microsoft Typography site on Font Embedding for the Web.

Downloaded fonts are only temporarily installed on the user’s machines for use by the particular web page while the page is actively being used.

Monotype Imaging’s patented MicroType? Express font compression technology for fonts is used within embedded applications. The technology minimizes memory usage for font data storage in resource-constrained environments, where both ROM and RAM savings are critical. Small font files are built without sacrificing the qualities, features and capabilities of OpenType? and TrueType? fonts.

MicroType? Express algorithm. The MicroType? Express algorithm is a lossless compression algorithm for OpenType/TrueType fonts, which was developed by Monotype Imaging. Monotype Imaging has indicated that they own one or more patents that relate to the MicroType? Express algorithm.

Suggested action

Monotype Imaging would like input from W3C and the community on the best way to achieve W3C’s adoption of the EOT Submission that includes the Monotype MicroType Express compression technology.

We suggest that the Consortium start a Working Group whose mission is to produce a W3C Recommendation for EOT by refining the Submission, addressing implementation experience and interoperability feedback from the Submission.

Resources

To help with this work, we expect we expect to provide assistance as needed to the Consortium.
