At the most basic, a feed is a list of content from Mercury. Feeds let you organize any content from Mercury — your own and others' — and then display it on other web sites. The two most common types of content you will find in feeds are either events or news.
Manual vs. Automated
Content can be organized two ways in Mercury:
- as an arbitrary "Manual" feed, where you have complete control but must make every change yourself, or
- via a selection of rules in an "Automated" feed that you set and forget.
Examples of Automated Usage
- Commonly, people use relative dates, limit them to just one type of content (such as events only), and then connect these to hg_reader blocks and pages on their web site.
- However, you can also use these to find related content, without connecting the feed to a website (thanks to Kathleen Moore for this idea!). For example, you could make an automated feed that helps you curate content you might add to a manual feed. It could search by keywords, or show content from other people's groups.
Examples of Manual Usage
Commonly, people use this to control which news stories or events show up on the homepage of their website.
The only drawback to a manual feed is that nothing is added or removed from them, without someone's intervention.
Readers allow your web site to pull in the feeds you create and display them on your site. Georgia Tech's Institute Communications offers a Drupal module, HG Reader, for getting this set up.
Note Feed Limits
As of the September/October Mercury refresh, all feeds can now only contain a maximum of 200 items.
- For an automated feed, any items beyond 200 items will not be displayed.
- For a manual feed, any new items beyond 200 will not be added.
