What is XSP ?
"Simple manner you write content in one place and have it published somewhere else"
Cross-Site Publishing is very simple publishing is a feature driven method that lets you create and maintain content in one or more authoring site collections or web application and publish or display this content in one or more publishing site collections by using content Search Web Parts.
Cross-site publishing complements the already existing publishing method, author-in-place, where you use a single site collection to author content and make it available to readers of your site.
An authoring site(Product Site) is where authors go to create and host content; think of it as the source in XSP. This is where a list that is marked as a catalog lives.
- A catalog is an attribute that you can add to a list or a library in the authoring site. Marking a list or a library as a catalog makes the content easily accessible to other site collections.
- Search is the engine that connects your catalog to a publishing site.
- The term store holds metadata terms that are used to organize content for publishing on target sites.
- A publishing site is where visitors go to see and read content & where the content needs to be publish.
