Cross-publishing means allowing content items in one publication to also appear in sister publications served by the same Content Engine.
The Content Engine fully supports cross-publishing: borrowed content items adopt the layout of the publication section in which they appear and are indistinguishable from native content items. There are, however, a few restrictions that must be observed in order to ensure problem-free cross-publishing. Publications can only borrow content items from each other if:
They have identical content types. This means that the content types in both publications must have:
Identical fields with identical names

You can set up cross-publishing so that editorial staff not only have access rights to content items in a sister publication, but editorial rights too (that is, they will be allowed to modify content items in the sister publication). In this case the publications must have identical layout definitions. Note, however, that editorial staff can never create content in anything other than their home publication, whatever access rights they have in other publications.
Cross-publishing does not require identical templates, only identical content-type, image-version and layout-group publication resources. Nor does the use of cross-publishing have any consequences for the template developer. Given identical publication resources, cross-publishing is an administration/editorial issue, and can be set up using Web Studio.
