I have to implement a Google Custom Search for a website. The website has different content types. One of them is a "publication". A publication consists of different fields:
- Title
- Author
- Published date
- Document
- Document type
Document is the URL to a PDF, Text, MS-Word, etc. document. And Document type is, as you can expect, the document type (ie. PDF, DOC, TXT, etc).
I will need this information to be in the Rich Snippet because I have to format the search results differently for each document type (ie. include a different icon, etc).
What schema should I be using for that? I could not find information about how to structure data for that kind of content. Can I use anything from Schema.org? Or should I create my own? Any idea?
Thanks in advance for any input on that.
