ActivityPub is now a W3C Recommendation
23 January 2018 | Archive
The Social Web Working Group has published ActivityPub as a W3C Recommendation.
ActivityPub is a decentralized social networking protocol based upon the ActivityStreams 2.0 data format. It provides a client to server API for creating, updating and deleting content, as well as a federated server to server API for delivering notifications and content.
ActivityPub is already implemented and deployed to a number of projects and a wide userbase, including over 1 million registered users across thousands of Mastodon instances. ActivityPub allows software projects both small and large to build social network offerings into their systems. Adding ActivityPub support allows interoperable social networking between applications with entirely different codebases. For example, Mastodon and PeerTube users are able to use ActivityPub to allow users to share videos and comment across different servers.
Upcoming Workshop: Data Privacy Controls and Vocabularies
26 January 2018 | Archive
W3C announced today a W3C Workshop on Privacy and Linked Data, April 17-18 2018, in Vienna, Austria. The event is hosted by WU Vienna.
The primary goal of the workshop is to explore interoperability in privacy and compliance expressions using Linked Data. But based on transportable linked data, many privacy concepts can be created.
Expected topics of discussion include:
- Privacy and Transparency in Linked Data
- Identity management vocabularies
- Categories of sensitive and personal data
- Modeling/Interlinking aspects of privacy and provenance
- Modeling consent and making it transportable
- Vocabularies to model privacy policies, regulations, and involved (business) processes
- Modeling permissions, obligations, and their scope in dealing with personal data
- Reasoning about formally declared privacy policies, in order to detect policy violations, breach and enforce policies
- Exploring links and synergies using Linked Data vocabularies in the context of related efforts such as W3C’s Social Web WG, Verifiable Claims WG, ODRL/POE WG, Credentials CG, and PROV WG or other (non-W3C) efforts (e.g. OASIS XDI, OASIS COEL,
Kantarainitiative’s CISWG)
- Visualizations of data and policy information to help data self determination
For more information on the workshop, please see the workshop details and submission instructions.
Registration is available online due by 02 April 2018.
WebSub is now a W3C Recommendation
23 January 2018 | Archive
The Social Web Working Group has published WebSub as a W3C Recommendation.
WebSub provides a common mechanism for communication between publishers of any kind of Web content and their subscribers, based on HTTP web hooks. Subscription requests are relayed through hubs, which validate and verify the request. Hubs then distribute new and updated content to subscribers when it becomes available. WebSub was previously known as PubSubHubbub.
