*An '''Item''' represents minimal unit of content managed in the eSciDoc repository. Each Item comprises of:
**at least one '''MetadataRecord''' i.e. one or more metadata descriptions of the overall content of the item
**zero or more '''Component''' -  the actual (or externally referenced) content and at least one metadata description
eSciDoc data model additionally defines the concept of a '''SurrogateItem''' as a "proxy" object to a resource which can reside in or outside the eSciDoc repository. See also [[ESciDoc_Logical_Data_Model/SurrogateItem|SurrogateItem]] for more details.
