Feature Request: JSON Feed support

[weierophinney]

Would be awesome if Zend Feed supported parsing JSON feeds. Publishing and parsing them is much more straightforward and lightweight compared to RSS and Atom, and adoption is starting to pick up.

It would be good, but I'm very wary of a month old standard which all but states that Version 1 may be the only version ever needed. Talk about hubris... The problem with these random drop standards, regardless of who writes them, is their isolation/lack of feedback during development. The issue tracker is littered with basic questions, improvements and problems that seem to firmly point to a Version 2 being needed sooner rather than later.

That said, all wariness aside, it should be relatively easy to add but I would expect support to need an overhaul in time to remain relevant. The spec and Atom/RSS mappings also needs a close reading, and it may be prone to disruption if a major JSONFeed publisher starts hacking in some customisations.

Then again, isn't that all new stuff in a nutshell? :)

I think major feedreader support it : feebin.com, inoreader.com etc. not sure how much work needed, but will be great if we add json feed support.

The problem so far has been that there was no schema which can be used for validation. But now there are schemas for version 1.0 and 1.1 of "JSON Feed": https://github.com/sonicdoe/jsonfeed-schema

I already created a prototype for reading a JSON feed but for the writing part we need to split the Laminas\Feed\Writer\Renderer\RendererInterface because it's based on XML output:

laminas-feed/src/Writer/Renderer/RendererInterface.php

Lines 23 to 42 in 254bfab

	/**
	* Save feed and/or entry to XML and return string
	*
	* @return string
	*/
	public function saveXml();
	/**
	* Get DOM document
	*
	* @return DOMDocument
	*/
	public function getDomDocument();
	/**
	* Get document element from DOM
	*
	* @return DOMElement
	*/
	public function getElement();

Ah yep, closing+locking until I see real traction on that spec.
