What it does
A POWERFUL NEW PROTOCOL FOR DEVELOPERS Build and use interactive blocks connected to the world of structured data An open standard for building and using data-driven blocks. Make your applications both human and machine-readable.
A standardized way to create blocks whose contents are mapped to schemas, which are both human and machine-readable.
Blocks are individual front-end components that display data. They allow regular users to edit their contents without needing to write code. Blocks can be simple and static, like an image or a text block, or they can be more complex, like a checklist or chart block. Users select the type of block they want, then add it to their page, dashboard, or canvas. They can add content to the block, edit it, or manipulate it to do what they need. Every app has to build all of their own blocks. This means developers are rebuilding the same block types over and over. Open source components can save some time, but still need to be individually integrated. This also limits how many blocks users have…from blockprotocol.org

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
