We are using custom content types that inherit from document sets. These document sets have metadata, which we would like to use in web parts on the document set's welcome page.
For example: we would like a tag-based content search in our site collection for any content that uses the same tag as our document set. To make things more real: we have a content type "animals" that is a document set plus metadata; one of these fields is a managed metadata field "animal name", and we would like to pull all photographs that we have in our site collection with the same tag into the document set's welcome page via a web part.
Is that possible? How? If not: is there some way to achieve something similar?
Solution for SP2013 preferred.
