Need support for more common data types such as pdf and/or a better separation of the information shown in the InfoView. It doesn't make sense that we can't show at least the author/date/etc for ALL data types since no matter the content type, they all share this in common. The previews should simply add support to provide more information about the content type (e.g. a view to scroll through a text file, or to add a small preview of the pdf file). Eventually, something like DatasetBeanPage might be what we need so we can at least show basic information about a dataset.
