You've probably already figured things out since it's literally been over a year since you posted your question, but here's what we're currently working on -

We're using Article as the basis for the schema we're adding to case studies, and including the following:

• Headline

• Description

• Publisher

• Name

• Logo

• Date published

• Date modified (if applicable)

• Image

• URL - canonical URL

• Article body

• Award

• Mentions

• associatedMedia

We've been toying with finding a way to try to incorporate exampleOfWork and workExample, but don't feel like it's quite the right fit. Depending on the content you've got in your case studies, there are loads of great elements to work in from the Article type.

Where did you end up?
