F.4 Basic Directory IOD Information Model

The Basic Directory IOD Information Model defines the relationship between the various types of Directory Records that may be used in constructing DICOM Directories. This model is based on the DICOM Application Model defined in this part of the DICOM Standard. Entities in this Model correspond to Directory Records (DR). These are shown as rectangular boxes. Each Directory Record in this model is part of a Directory Entity (not shown except for the Root Entity) that is referenced by a Directory Record of a higher-level Directory Entity (e.g., a Study Directory Record references a Directory Entity that includes Directory Records describing the content of the Study).

Each Directory Record has a number of mandatory and optional keys that are not shown on this model. They are defined in Section F.5. Conventions used are those used by this part of the DICOM Standard. The model is depicted as an entity/relationship model in Figure F.4-1. These Directory Record relationships are fully specified in Table F.4-1.
