RESTful Best Practices - How to name a report resource

I am creating a RESTful API and following best practices for it and I became in a big doubt with this.

I need to create a report (with charts, and data tables) that it's made of analyze another resources (evaluations), and many other params makes this report to be variable on the data that shows.

So, looking for best practices, I don't know if I need to get all the data, and process it at Javascript, to make the report (client side) so the RESTful pattern is not a problem;

Or how can I name a resource "report" that is made of many other resources. My non restful mind wants to create a /api/rest/reports/executiveReport?evaluation=:id&competences=:id&competences=:id&employee=:id uri

How can I achieve this in a beautiful RESTful pattern uri? I don't want to process the data at Javascript, as there are many errors, or exceptions that I can't catch. I prefer to deliver the report to be shown.

Thanks!
