Hackathon

Hackathon is an Event subtype for hackathons, code jams, coding competitions, and collaborative programming events. It adds no properties of its own. Use offers for registration (often free), maximumAttendeeCapacity for team limits, and about to describe the hackathon challenge or theme.

For a complete property walkthrough, see the Event example. Every property shown there applies to Hackathon. Replace "@type": "Event" with "@type": "Hackathon".

Common Hackathon mistakes

Mistakes that pass validation but silently fail to earn rich results or mislead consumers walking the graph. Avoid these and your markup will be ahead of most sites in the wild.

01
Using generic Event for a hackathon
Wrong
```
"@type": "Event" for a coding competition or hack day
```
Right
```
"@type": "Hackathon"
```
