We give an overview of existing interoperability-focused standards and protocols useful to the MyData audience, covering their history, the classic centralized and federated approaches, and the new set of decentralized and self-sovereign ones. We’ll talk about where each approach is appropriate, how the various standards can interact, and what possible upgrade paths could be.
Categories of technologies include: Identity (e.g. DIDs) and Verifiable Credentials, Authentication (e.g. DID-Auth), Access Control, Aggregation and Federation (e.g. the new W3C ActivityPub and ActivityStreams2 specs), and Personal Data Store APIs (e.g. Solid).

ActivityPub: a W3C Technical Recommendation for Federated Social Networking
Benjamin Goering

In January of 2018, the World Wide Web Consortium Social Web Working Group published the final versions of two standards: (1) ActivityStreams vocabulary for describing social data and activities on the web and (2) ActivityPub protocol for federated social networking. Both were quickly adopted by Mastodon, an open source TweetDeck-style web application. Come learn about how what these standards say, how they work together, and how you can implement them to break down the silos of the closed-source social networks.
