The organization of the institutions is supposed to copy the kind and manner wie DSpace organizes the data. At uppermost place the Communities which can be organized even again hierarchically stand. Collections which for example topics summarize has every community and/or under-community. Collections can belong to several to Communities. The actual archive element is the item which can be heard to a Collection, but referenced in several Collections. The metadatas of the archive object appertain to the item. The items themselves are again organized in Bundles of bit streams. By the Bundles is allowed, that archive objects can consist of more than only a file (for example web pages with the relevant pictures), because the Bundles consist of a or several bit streams, the actual data. The item can consist, however, of more than a Bundle. A customary division of the Bundles is: Original, thumbnails, text (for the indexing). For every bit stream also the format bit stream which describes the model MIME and the tiers of the support (confessed, supplementary , not supplementary) must be indicated.
The standard extent of the metadatas of an item grasps the Dublin Core, plus some descriptive information for the other tiers of the data organization. The metadatas are still complemented with administrative metadatas, that refer to the origin and storage of the data and structural metadatas that describe the relationship of the bit streams under each other.
