SPARQCode

A SPARQCode is a matrix code (or two-dimensional bar code) encoding standard that is based on the physical QR Code definition created by Japanese corporation Denso-Wave.

Overview

The QR Code standard as defined by Denso-Wave in ISO/IEC 18004 covers the physical encoding method of a binary data stream.[1] However, the Denso-Wave standard lacks an encoding standard for interpreting the data stream on the application layer for decoding URLs, phone numbers, and all other data types. NTT Docomo has established de facto standards for encoding some data types such as URLs, and contact information in Japan, but not all applications in other countries adhere to this convention as listed by the open-source project "zxing" for QR Code data types.[2][3]

The SPARQCode encoding standard specifies a convention for the following encoding data types.

The SPARQCode convention also recommends but does not require the inclusion of visual pictograms to denote the type of encoded data.

gollark: Hmm, I could actually make infipage work with the service worker thing by implementing the rewrite-rule logic on the client.
gollark: It might also™ be possible to have it cache *all* the site on every website update, but that would be a bit wasteful.
gollark: This™ does have the minor disadvantage that™ you'll need to refresh the page™ to receive site updates™ sometimes™, so that™ it loads the service worker™ again to detect™ the new™ version.
gollark: If you visit a page, it will now use magic™ to cache it locally, and then serve that local copy until it detects that the site has been updated, and that will continue to work even without an Internet connection with cached pages.
