An open standard for data-driven blocks
Protocol Buffers
Protocol Buffers are language-neutral, platform-neutral extensible mechanisms for serializing structured data.
Exploring Notion's Data Model: A Block-Based Architecture | Notion
Notion’s data model enables the product’s most foundational component: blocks. Through blocks, we allow users more flexibility over their information.
Solid Protocol
This document connects a set of specifications that, together, provide applications with secure and permissioned access to externally stored data in an interoperable way.
Block - Open Source
By collaborating in the open, we create higher quality software, hardware, and protocols through relentless collective examination, and also ensure our systems, hardware, and protocols evolve to meet real-world needs.

A Conflict-Free Replicated JSON Datatype
Many applications model their data in a general-purpose storage format such as JSON. This data structure is modified by the application as a result of user input. Such modifications are well understood if performed sequentially on a single copy of the data, but if the data is replicated and modified concurrently on multiple devices, it is unclear what the semantics should be. In this paper we present an algorithm and formal semantics for a JSON data structure that automatically resolves concurrent modifications such that no updates are lost, and such that all replicas converge towards the same state (a conflict-free replicated datatype or CRDT). It supports arbitrarily nested list and map types, which can be modified by insertion, deletion and assignment. The algorithm performs all merging client-side and does not depend on ordering guarantees from the network, making it suitable for deployment on mobile devices with poor network connectivity, in peer-to-peer networks, and in messaging systems with end-to-end encryption.

Taking AT to the IETF - AT Protocol
We recently posted two drafts to the IETF Data Tracker. This is the first major step towards standardizing parts of AT in an effort to establish long-term governance for the protocol.
The 2026-07-28 Specification
The 2026-07-28 Model Context Protocol specification is out, bringing a stateless protocol core, Multi Round-Trip Requests, header-based routing, cacheable list results, authorization hardening, a formal extensions framework, and updated Tier 1 SDKs.
