Template Hub for SharePoint
The SharePoint Template Hub makes it possible for you to have a centralized repository for your templates.
It solves the issue with one-to-one relationships between Content Types and Templates by splitting this up, and give you the possibility to reuse a content type for several templates without any implications. All templates can also have metadata connected to them that will come over to the document when it is saved in the target document library. The document template repository is a standard SharePoint Document Library, thus it supports all the standard metadata, publishing and workflow features for working with your document templates, just like you would expect with regular documents.
The site administrators can configure the end user experience for the Template Selector using views, filters and columns, and you get live previews of your templates as well as sorting, filtering and search.
