Transclusion    (OYW)

A term (believed to be) coined by Ted Nelson that refers to the inclusion of part of a document into another document by reference. A very similar feature, that was simply called "include," has also been available on the NLS oNLineSystem implementation by DougEngelbart and his ARC (Augmentation Research Center at Stanford Research Institute, Menlo Park, California, USA) team back in the 1950's.    (OYX)
