Regarding Universal Data Element Framework
see à [287]
Communication from Antoinette Arsic to ONTAC working group
With regard to the UDEF Object Class List, just a note:
Coming from the library and information science realm, this
reminds me of the history of faceted classification.
Three best-known faceted universal classification systems: the
Colon Classification and the second edition of the Bliss Bibliographic
Classification (BC2).Ranganathan's Colon Classification has five facets, now
classic (see Ranganathan (1962), among his many books, for an introduction to
the facets and how to use them):
* Personality (the something in question, e.g. a person or event
in a classification of history, or an animal in a classification of zoology)
* Matter (what something is made of)
* Energy (how something changes, is processed, evolves)
* Space (where something is)
* Time (when it happens)
* These five, known as PMEST, may be enough for you.
* If you need more, look
to Bliss Bibliographic Classification for ideas (Broughton 2001, 79):
* thing/entity
* kind
* part
* property
* material
* process
* operation
* patient
* product
* by-product
* agent
* space
* time

"The smaller the domain, the more specific and detailed the
facets can get. There is little or no need to deal with the complications
inherent in organizing the world of knowledge, and the system can be as precise
as necessary to do what is needed. Here follow some examples of smaller
classifications, beginning with the Art & Architecture Thesaurus (Petersen
1994, 26), which is not actually a classification scheme, but is indeed
faceted. Note how some of the classifications are based on Ranganathan's
Personality, Matter, Energy, Space, and Time."
* Associated Concepts (e.g., philosophy)
* Physical Attributes (density)
* Styles and Periods (Simulationist) (similar to Space and Time)
* Agents (People/Organizations) (lighthouse keepers)
* Activities (thinking) (similar to Energy)
* Materials (plywood) (similar to Matter)
* Objects (bunk beds) (similar to Personality)
