Of course, also in eZ Publish it has always been possible to create an RSS feed. These will include items based their location in the content hierarchy. I have developed this extension to create RSS feeds based on tags given to each page, which makes it possible to create RSS feeds with just those items that one is interested in. Similar to the categories feed in WordPress, e.g. https://www.harryonline.net/category/ez-publish/feed
