public class VirtualEadImporter
extends EadImporter

Import EAD describing a Virtual Collection. some rules governing virtual collections:

the archdesc should describe the purpose of this vc. it can not in itself refer to a DU.

every c level is either 1) a virtual level (=VirtualLevel), or 2) it points to an existing DocumentaryUnit (=VirtualReferrer) (and consequently to the entire subtree beneath it) 1) there is no repository-tag with a ehri-label

2) there is exactly one repository-tag with an ehri-label <repository label="ehri_repository_vc">il-002777</repository> (this will not be shown in the portal) and exactly one unitid with a ehri-main-identifier label, that is identical to the existing unitid within the graph for this repository

all other tags will be ignored, since the DocumentsDescription of the referred DocumentaryUnit will be shown. there should not be any c-levels beneath such a c-level

Method Detail

importItem

public AbstractUnit importItem(Map<String,Object> itemData,
                               List<String> idPath)
                        throws ValidationError

Import a single archdesc or c01-12 item, keeping a reference to the hierarchical depth. this will import the structure as VirtualUnits, which either have a DocDescription (VirtualLevel, like series) or they point to an existing DocDesc from an existing DocumentaryUnit (VirtualReferrer).

Specified by:

importItem in interface ItemImporter<Map<String,Object>,AbstractUnit>

Overrides:

importItem in class EadImporter

Parameters:

itemData - The data map

idPath - The identifiers of parent documents, not including those of the overall permission scope

Returns:

the imported node

Throws:

ValidationError - when the itemData does not contain an identifier for the unit or...

extractRelations

protected Iterable<Map<String,Object>> extractRelations(Map<String,Object> data)

Overrides:

extractRelations in class EadImporter

                        throws ValidationError

Description copied from interface: ItemImporter

Import an item representation into the graph, and return the Node.

Specified by:

importItem in interface ItemImporter<Map<String,Object>,AbstractUnit>

Overrides:

importItem in class EadImporter

Parameters:

itemData - the item representation to import

Returns:

the imported node

Throws:

ValidationError - when the item representation does not validate
