E-911 location standards and location commercial services

Mobile location positioning technologies, initially developed in answer to the U.S. Federal Communications Commission (FCC) E-91 I requirement have become an increasingly important topic in the standards development group. The U.S. FCC has mandated that by October 2001, mobile callers to E-9l I must he located to within a certain accuracy level (i.e., 50m in 67% of cases and 1 50m in 95% of cases for handset-based location solution). This requirement, coupled with the consumer demand for location commercial services, has driven the cellular industry to research promising positioning techniques and new location value-added services.

W3C Announces MathML 3, New Standards for Math on the Web

W3C has announced the third version of its standards for the inclusion of mathematical expressions in Web pages. MathML (Mathematical Markup Language) is aimed to make math on the Web more accessible and more international. While the basic markup remains the same, this version brings to it some improvements for assistive technology, as well as for formulas in languages that are written from right to left.

The MathML standard is supported in a number of applications already, beyond just websites - eBooks, equation editors, screen readers, braille displays, and computational software, for example. And it's part of the larger W3C Open Web Platform, which includes HTML5, CSS and SVG.

As browsers expand their support for HTML5, MathML support will be included. This means that embedding math in Web documents will become easier, and math software can more easily publish to HTML.

In announcing the new version, W3C stresses three areas: accessibility, education, and international interoperability. As testimony from Adil Allawi, Technical Director of Diwan Software Limited, an Arabic language software publisher makes clear, math - on the Web at least - is yet to be an "international language": "We have been working for the past five years converting Arabic school books to electronic documents, but we have always faced problems with mathematical books which rely on custom layout and fonts," he says.

An Example of MathML

Here's an emaple of how MathML works in order to represent the equation "x squared plus 4x plus 4 equals 0 The first example uses presentational tags, the second semantic tags.

Leaked Letter — BSA Pressures Europe To Kill Open Standards

An anonymous reader writes "The Business Software Alliance is trying to kill open standards. Free Software Foundation Europe has gotten hold of a letter in which the BSA tries to bully the European Commission into removing the last traces of support for open standards from its IT recommendations to the public sector. FSFE published the BSA's letter (PDF), and picked apart its arguments one by one."
