Philipp Zumstein proposed a concept of the scope of holdings. This concept is just a suggestion to see if our "real world entities" fit in. The table does not propose that all entities listed here should be described in an Holdings-Ontology.

Status: Please feel free to edit this page and add new or rearrange entities.

comment on the holding description 
holding Institutionck: (relations between a holding and an agent) daia:heldBy --> holding:heldBy
relations between a holding and another holdingck: daia:narrowerExemplar -> holding:narrowerExemplar , daia:broaderExemplar -> holding:broaderExemplar , daia:narrowerExemplarOf -> holding:narrowerExemplarOf , daia:broaderExemplarOf -> holding:broaderExemplarOf
enumeration and chronology

ck: the description of enumeration and chronology of a periodical (ecpo:hasBestandsverlauf)

inter library loan

 

ck: ill code vocabulary as range (holding:ill)
Date of Reportck: on which the holdings statement was created or last updated

Type of Unit Designator

ck: (see z39.71)

0 (zero) -->Information not available; Not applicable

a --> Basic bibliographic unit

c --> Secondary bibliographic unit: supplements, special issues, accompanying material, other secondary bibliographic units

d --> Indexes

Physical Form Designatorck: (see z39.71) specifies the physical form of the unit. Typically this information resides in the title description, but there is also the possibility to catalouge independent from the physical form. Maybe dcterms:medium with RDA Carrier Types http://metadataregistry.org/vocabulary/show/id/46.html

Completeness Designator

ck: (see z39.71)

0 (zero) --> Information not available, or Retention is limited

1 --> Complete (95%-100% held)

2 --> Incomplete (50%-94% held)

3 --> Very incomplete or scattered (less than 50% held)

4 --> Not applicable

 

Retention Designator

ck: (see z39.71)

0 (zero) --> Information not available

1 --> Other

2 --> Retained except as replaced by updates

3 --> Sample issue retained

4 --> Retained until replaced by microform, or other preservation format

5 --> Retained until replaced by cumulation, replacement volume, or revision

6 --> Limited retention (only some parts kept)

7 --> No retention (no parts kept)

8 --> Permanent retention (all parts kept permanently)

Name of Unitck: (see z39.71) name of unit is usually given only when the holdings of a secondary bibliographic unit are being recorded. For single-part secondary units, the name of unit may be the only data element required to express Extent of Holdings
Extent of Unitck: (see z39.71) extent of unit is usually given only when a unit lacks sequential designations. This occurs most frequently with non-serial units.

service portfolio

entity descriptioncomments
holding related serviceck: A service might not be a property of a holding but of an agent?
  
  
  

current status

entity descriptioncomments
availabilityck: might be related to a service and expressed with DAIA
currently in the collection of an Agent 

eventually not in the collection yet (ordered, in processing ...)

 

eventually not in the collection anymore (stolen, missing, destroyed, withdrawn...)

 

Acquisition Status Designator

ck: (see z39.71) also see current status

0 (zero)  --> Information not available, or Retention is limited

1 --> Other

2 --> Received and complete or Ceased

3 --> On order

4 --> Currently received

5 --> Not currently received

entity descriptioncomments
relation between a title/description and an holdingck: daia:exemplar -> holding:exemplar see corresponding title
relation between an agent and an holdingck: daia:holds -> holding:holds see relations between a holding and an agent

location

entity descriptioncomments
Institution Identifierck: not a relation between a holding and a institution, but an identifier where the holding resides (see z39.71)
Sublocation Identifierck: a subdivision or collection within the institution represented by the institution identifier (see z39.71)
Copy Identifierck: The copy identifier element may be used to record holdings for one or more copies
call number / label (local)ck: ZETA ((Sonder-)Standortsignatur), ISO20775 (shelfLocator ?), Z39.71 (Call Number), MARC21 (Shelving control number ?)
