WebSub
WebSub (formerly PubSubHubbub) is an open protocol for distributed publish–subscribe communication on the Internet. Initially designed to extend the Atom (and RSS) protocols for data feeds, the protocol can be applied to any data type (e.g. HTML, text, pictures, audio, video) as long as it is accessible via HTTP. Its main purpose is to provide real-time notifications of changes, which improves upon the typical situation where a client periodically polls the feed server at some arbitrary interval. In this way, WebSub provides pushed HTTP notifications without requiring clients to spend resources on polling for changes. In October 2017, PubSubHubbub was renamed to WebSub for simplicity and clarity. , the WebSub protocol has been adopted by the W3C as a Recommendation. Protocol Under WebSub, there is an ecosystem of publishers, subscribers, and hubs. A subscriber first retrieves content from an HTTP resource ( URL) by requesting it from the webserver. The subscriber then inspe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superfeedr
Superfeedr is a feed API built on WebSub, which is sometimes referred to as PuSH. It transforms a variety of feeds into standardized RSS, Atom, or JSON format and distributes (or "pushes") them via WebSub or XMPP. This allows subscribers to receive new notifications or updated content from their feeds and publishers to send those notifications. History Superfeedr was launched by in 2009 by parent company Notifixious. While Notifixious' website went offline sometime between September 23, 2009 January 5, 2010, Superfeedr has remained online and available. While the website of Notifixious, the parent company of Superfeedr, is no longer available Superfeedr continues to refer to it in the terms of service for the site. Superfeedr was bought by Medium in 2016. Technology PuSH is a protocol that relies on webhooks to push feed updates in real-time from publishers to subscribers in a decentralized manner. PuSH builds on existing protocols, ensuring that polling infrastructures currentl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RSS To Email
RSS ( RDF Site Summary or Really Simple Syndication) is a web feed that allows users and applications to access updates to websites in a standardized, computer-readable format. Subscribing to RSS feeds can allow a user to keep track of many different websites in a single news aggregator, which constantly monitor sites for new content, removing the need for the user to manually check them. News aggregators (or "RSS readers") can be built into a browser, installed on a desktop computer, or installed on a mobile device. Websites usually use RSS feeds to publish frequently updated information, such as blog entries, news headlines, episodes of audio and video series, or for distributing podcasts. An RSS document (called "feed", "web feed","Web feeds , RSS , The Guardian , guardian.co.uk", ''The Guardian'', London, 2008, webpage: GuardianUK-webfeeds. or "channel") includes full or summarized text, and metadata, like publishing date and author's name. RSS formats are specified ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RSS Cloud
RSS Cloud is an optional sub-element of the RSS protocol's <channel> element that enables realtime (immediate) push notifications or distributed publish/subscribe communication for feeds. This is done using a element allowing a software service to register with a cloud which notifies subscribers of updates to the channel. RSS Cloud is not limited to RSS feeds but can also be used with other feed formats such as Atom. On September 7, 2009 WordPress became the first large supporter of the protocol, enabling the tag for over 7.5 million hosted blogs on WordPress.com. Another protocol superseding the use of the <cloud> element is WebSub WebSub (formerly PubSubHubbub) is an open protocol for distributed publish–subscribe communication on the Internet. Initially designed to extend the Atom (and RSS) protocols for data feeds, the protocol can be applied to any data type (e.g. HTM ....

Publish–subscribe Pattern
In software architecture, publish–subscribe is a messaging pattern where senders of messages, called publishers, do not program the messages to be sent directly to specific receivers, called subscribers, but instead categorize published messages into classes without knowledge of which subscribers, if any, there may be. Similarly, subscribers express interest in one or more classes and only receive messages that are of interest, without knowledge of which publishers, if any, there are. Publish–subscribe is a sibling of the message queue paradigm, and is typically one part of a larger message-oriented middleware system. Most messaging systems support both the pub/sub and message queue models in their API; e.g., Java Message Service (JMS). This pattern provides greater network scalability and a more dynamic network topology, with a resulting decreased flexibility to modify the publisher and the structure of the published data. Message filtering In the publish-subscribe mod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diaspora (social Network)
Diaspora (stylized as diaspora*) is a nonprofit, user-owned, distributed social network. It consists of a group of independently owned nodes (called ''pods'') which interoperate to form the network.

The project was founded by Dan Grippi, Maxwell Salzberg, Raphael Sofaer and Ilya Zhitomirskiy, students at New York University's Courant Institute of Mathematical Sciences. The group received crowdfunding in excess of $200,000 via ''Kickstarter''. A consumer alpha version was released on 23 November 2010. Diaspora software is licensed under the terms of GNU-AGPL-3.0. Its development is managed by the Diaspora Foundation, which is part of the Free Software Support Network (FSSN). The FSSN is in turn run by Eben Moglen and the Software Freedom Law Ce ...
