Wikicat Technical Design/Enumerated Types
Wikicat enumerated types are sets of values defining individual types which are then used in the attribute type definitions of actual entities in the model. In relational database terms, an enumerated type is simply a table (1 table defines 1 type) with a set of controlled, usually seed-only values. Every entity table having a column of one of these types will store a "foreign key" to it. Note, though, that this foreign key is not for the purposes of normalization, since the enumerated type has no other data. Rather, it is for the purposes of value control.
Model Entity Type
editDefines the entity types in the model using entities derived from Functional Requirements for Bibliographic Records (pp. 13-16) and Functional Requirements for Authority Data (pp. 7-15). Used to allow "multi-table" foreign keys where a relationship can exist between one type of entity and several others. For example, a Manifestation, a Work, and an Expression all have titles associated with them.

Information Nominality
editNominality or actuality of any particular Wikicat data. Used to modify another data column to indicate whether its "purely bibliographic" data is:
- nominal-only: information appears on the item but is not actually true in the real-world and hence is not modelled within Wikicat
- actual-only: does not appear on the item but was provided by the cataloger and hence is modelled (on the good-faith assumption it is true in the real-world)
- actual and nominal: information is both true (modeled) and appears on the item
- mixed: information taken from the item is intermixed with the cataloger's corrections/modifications; the cataloger information is modelled
- neither: information does not exist on the item nor can it be provided reliably by the cataloger
For catalog data formulated according to ISBD principles, the actual data appearing on the item is always transcribed, with cataloger corrections contained within brackets- '[' and ']'- following or interspersed with the data. Examples of each type of information nominality for possible imported data follows:
- actual and nominal:
- 2nd ed., 2nd printing
- actual-only:
- [2nd ed., 2nd printing]
- nominal-only:
- 2nd ed., 2nd printing [ sic ]
- mixed:
- 2nd ed., [2nd printing]
- neither:
- [2nd ed., 2nd printing?]
- [ s.n. ]
See ISBD(M): 0.10 Misprints for the formal ISBD rules on transcribing incorrect data. In the future Wikidata may have direct support for such complex modelling requirements.

Though most identifier schemes are for Manifestation entity types, there are several schemes for Work entities:
- ISTC (International standard text code)
- OWI (OCLC work identifier)
- ISWC (Musical works)
- ISAN (Audio-visual works)
Common schemes at the manifiestation level are:
- ISBN
- ISSN (serial)
- ISMN (music)
- v-ISAN
- DOI
- Handle
- ARK
- LC and other national bibliography identifiers
- OCN (OCLC control number)
See the ELAG 2010 Workshop on FRBR and Identifiers slides for more info.

Material-Specific Types
editClass of Material Type
editClass of material describes the class to which a Manifestation belongs, and determines which attributes are relevant to describing it. Class of material is a product both of content and form of physical carrier. Hence the inclusion of static graphical material, such as transparencies or slides, into the Projected Image class which more typically contains films and video recordings. The fact that a transparency or slide requires an external device to view outweighs the fact that it conveys a non-moving image.
