Learn about page templates with custom attributes. Access the data put in to a composer view from your page templates by getting the custom attributes.

But that's probably old school... if you learn to use c5 Express you'd probably use that as well... I just haven't learned how to do it that way yet so I use custom attributes in page templates linked to page types.

But if I was learning this for first time I would learn how to use Express to do things like this.
