This is a handy tool if you’re messing around with Twitter cards and other metacrap.
This is a great proposal that would make the Cache API even more powerful by adding metadata to cached items, like when it was cached, how big it is, and how many times it’s been retrieved.
A one-stop shop for all the metacrap you can put in the
head of your HTML documents.

Google’s pissing over HTML again, but for once, it’s not by making up
A new way to help limit which part of a page is eligible to be shown as a snippet is the “
data-nosnippet” HTML attribute on
This is a direct contradiction of how
data-* attributes are intended to be used:
…these attributes are intended for use by the site’s own scripts, and are not a generic extension mechanism for publicly-usable metadata.
This is brilliant technique by Remy!
If you’ve got a custom offline page that lists previously-visited pages (like I do on my site), you don’t have to choose between
IndexedDB—you can read the metadata straight from the HTML of the cached pages instead!
This seems forehead-smackingly obvious in hindsight. I’m totally stealing this.
Automatically generates icons and splash screens based on Web App Manifest specs and Apple Human Interface Guidelines. Updates manifest.json and index.html files with the generated images.
A handy command line tool. Though be aware that it will generate the shit-ton of
link elements for splash screens that Apple demands you provide for a multitude of different screen sizes.
Bruce wonders why Google seems to prefer separate chunks of JSON-LD in web pages instead of interwoven microdata attributes:
I strongly feel that metadata that is separated from the user-visible data associated with it highly susceptible to metadata partial copy-paste necrosis. User-visible text is also developer-visible text. When devs copy/ paste that, it’s very easy to forget to copy any associated metadata that’s not interleaved, leading to errors.
Manifest files can have categories now. Time to update those JSON files.
This document provides Best Practices related to the publication and usage of data on the Web designed to help support a self-sustaining ecosystem. Data should be discoverable and understandable by humans and machines.
If you’re going to make a manifest file for an existing site, start with this very handy tool. You give it the URL of your site and it then parses the content for existing metadata to create a best first stab at a manifest JSON file.
The way that Chloe has catalogued her music over time is fascinating. It’s like the Long Now opposite of This Is My Jam.
Richard would like your help. Take a few minutes to run through a card-sorting exercise to help classify fonts in a more meaningful way.
