First Public Working Draft: Trace Context Level 2

The Distributed Tracing Working Group has published a First Public Working Draft of Trace Context Level 2. This specification defines standard HTTP headers and a value format to propagate context information that enables distributed tracing scenarios. The specification standardizes how context information is sent and modified between services. Context information uniquely identifies individual requests in a distributed system and also defines a means to add and propagate provider-specific context information.

First Board of Directors to Initiate Critical Functions of W3C Inc.

The World Wide Web Consortium (W3C) is preparing to pursue 501(c)(3) non-profit status. Today, W3C is pleased to announce elections to its initial Board of Directors (Board) as the governing body of the W3C public-interest non-profit organization.

11 members are seated on the initial Board: 7 voting seats elected by the W3C Membership to bring a diverse multi-stakeholder perspective from the W3C Membership, and 4 voting seats representing the current Hosts institutions to ensure a global focus in the organization.

The following 7 people have been elected by W3C Membership to the initial Board: Robin Berjon, Koichi Moriyama, Mark Nottingham, David Singer, Eric Siow, Léonie Watson and Hongru (Judy) Zhu.

They will join representatives from our current Host institutions (Massachusetts Institute of Technology, USA; ERCIM, France; Keio University, Japan and Beihang University, China). The Host representatives on the Board will be announced shortly.

As Founding Director, Tim Berners-Lee will act as a non-voting, honorary, permanent Board member. Two additional seats will be filled by the Board to provide critical diversity, skill, or multi-stakeholder needs in the Board.

All Board terms are for two years, starting 1 October 2022 until 30 September 2024.

The W3C Board of Directors will be the governing body of the Consortium, have ultimate authority on its strategic direction, have a legal obligation to ensure that W3C implements its mission to lead the Web to its full potential, and have fiduciary responsibility over W3C as a whole.

First Public Working Draft: Mathematical Markup Language (MathML) Version 4.0

The Math Working Group has published a First Public Working Draft of Mathematical Markup Language (MathML) Version 4.0. MathML is a markup language for describing mathematical notation and capturing both its structure and content. The goal is to enable mathematics to be served, received, and processed on the World Wide Web, just as HTML has enabled this for text.

This specification is intended primarily for those who will be developing or implementing renderers or editors, or software that will communicate using MathML.

About 38 of the MathML tags describe abstract notational structures, while another about 170 provide a way of unambiguously specifying the intended meaning of an expression.

While MathML is human-readable, authors typically will use equation editors, conversion programs, and other specialized software tools to generate MathML.

MathML4 is the 4th version of the language, which started with MathML 1 in 1998.

Payment Request API and Payment Method Identifiers are W3C Recommendations

The Web Payments Working Group have published Recommendations of Payment Request API and Payment Method Identifiers.

Payment Request standardizes an API to allow merchants (i.e., web sites selling physical or digital goods) to utilize one or more payment methods with minimal integration. Browsers facilitate the payment flow between merchant and user. Payment Method Identifiers defines payment method identifiers and how they are validated, and, where applicable, minted and formally registered with the W3C.

Please see the disposition of comments following review by the W3C Membership.
