I'm currently working on a website for my student group, a performing team. The website will have upcoming performance information, so I thought I would use microdata to setup upcoming performances as structured data Events. On each performance page, the performance is given an itemtype of "Event".
The pages are correctly given this type, as can be seen by using Inspect Element on the webpage. But when I try looking at the page through Google's Structured Data Testing Tool, the type detected is "event", and so the custom Event itemprop's are seen as errors. Is there something I am doing wrong in my implementation of microdata?
