Payment Request API and Payment Method Identifiers are W3C Recommendations

8 September 2022 | Archive

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.

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

8 September 2022 | Archive

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.
