FAT-HUM CLASSIFICATION DATA MODEL
ELEMENT / ID / DEFINITION / CARDINAL. / OCCURENCE / VALUE TYPE / ERM /CLASSIFICATION
1 Classification heading / 1 / Single classification mark or span of compound and complex classification marks.
Each element of compound and complex classification mark has facet indicator. In database export these may needs sub-field tags also.
Purpose of facet indicators is to be able to access, search, file and control each meaningful element of complex number
Example 1: Single heading
590
Example 2: Compound heading
590A112(F36) / Mandatory / Non-rpt. / Text (coded value)
Common auxiliaries facet indicators (repeatable)
(A) = Language value
(B) = Form
(D) = Place
(E) = Ethnics
(F) = Time
(K) = Person
(L)= Materials
(M) = Property
(T) = Process
Other specifiers used accros classiication
A/Z = alphabetical ext
encode with <w> (non-repeatable)
* = extension by external systems
Main facet indicators (repeatable)
A = Theory
C = Time
D = Place
E = Agent
F = By-product
G = Product
H = Patient
J = Operation
K = Process
L = Material
M= Property
N = Part
P = Kind
S = Thing / n/a
1.1 Heading type / 2 / Indications of whether class mark is:
a) Single (non composed)
b) compound (class mark composed from two or more facets within one class)
c) complex (composed from two or more main classmarks or combination of class mark and main auxiliary)
This attribute is for management purposes only
Examples:
5907 Christianity = SM single main no.
5907N37 Christianity worshipers
=FM main number with facets
5907N37(D410) Christianity - Congregation - U.K.
= FMX: main no, facet, common auxiliary / Mandatory / Non-rpt. / Coded list:
SA - single common auxiliary
SM - single main number
FM - main number with facets
FMA -main number + facets followed by alphabetical extension
FFM - main number with sequence of two or more facets
FMX - number+ facet combined with common auxiliaries
CX – complex between main number and common auxiliaries
CXA – complex between two or more common auxiliaries
CXM -complex between two or more main classmarks
CXO - complex between FM and number outside classification

This data model is created to support faceted classification created for the FATKS project (http://www.ucl.ac.uk/fatks/) and served as a basis for FATHUM database tool. Data model and FATHUM are created with the classification building and maintenance functions. Its full exploitation comes with its implementation as an authority tool for information retrieval.
