universal
A Formal Theory of Substances, Qualities, and Universals, http://ontology.buffalo.edu/bfo/SQU.pdf
Alan Ruttenberg
Hard to give a definition for. Intuitively a "natural kind" rather than a collection of any old things, which a class is able to be, formally. At the meta level, universals are defined as positives, are disjoint with their siblings, have single asserted parents.
defined class
"definitions", in some readings, always are given by necessary and sufficient conditions. So one must be careful (and this is difficult sometimes) to distinguish between defined classes and universal.
A defined class is a class that is defined by a set of logically necessary and sufficient conditions but is not a universal
Alan Ruttenberg
named class expression
A named class expression is a logical expression that is given a name. The name can be used in place of the expression.
Alan Ruttenberg
named class expressions are used in order to have more concise logical definition but their extensions may not be interesting classes on their own. In languages such as OWL, with no provisions for macros, these show up as actuall classes. Tools may with to not show them as such, and to replace uses of the macros with their expansions
Barry Smith, Werner Ceusters
A denotator type indicates how a term should be interpreted from an ontological perspective.
Alan Ruttenberg
denotator type
The Basic Formal Ontology ontology makes a distinction between Universals and defined classes, where the formal are "natural kinds" and the latter arbitrary collections of entities.
All definitions, placement in the asserted IS_A hierarchy and required minimal metadata are complete. The class is awaiting a final review by someone other than the definition editor.

obsolescence reason specification
PERSON: Alan Ruttenberg
This is to be used when the original term has been replaced by a term imported from an other ontology. An editor note should indicate what is the URI of the new term to use.
term imported
term split
This is to be used when a term has been split in two or more new terms. An editor note should indicate the reason for the split and indicate the URIs of the new terms created.
placeholder removed
An editor note should explain what were the merged terms and the reason for the merge.
terms merged
We expect to be able to mine these new reasons and add instances as required.
This is to be used if none of the existing instances cover the reason for obsolescence. An editor note should indicate this new reason.
other
The term was used used in an attempt to structure part of the ontology but in retrospect failed to do a good job
failed exploratory term
Person:Alan Ruttenberg
The creation of this class has been inspired in part by Werner Ceusters' paper, Applying evolutionary terminology auditing to the Gene Ontology.
obsolescence reason specification
PERSON: Melanie Courtot
The reason for which a term has been deprecated. The allowed values come from an enumerated list of predefined terms. See the specification of these instances for more detailed definitions of each enumerated value.

placeholder
This isn't a class that OBI will keep - it's a placeholder for edits that are underway. The class name should start with an underscore
metadata complete
Class has all its metadata, but is either not guaranteed to be in its final location in the asserted IS_A hierarchy or refers to another class that is not complete.
uncurated
Nothing done yet beyond assigning a unique class ID and proposing a preferred term.
Class has undergone final review, is ready for use, and will be included in the next OBI release. Any class lacking "ready_for_release" should be considered likely to change place in hierarchy, have its definition refined, or be obsoleted in the next release. Those classes deemed "ready_for_release" will also derived from a chain of ancestor classes that are also "ready_for_release."
ready for release
metadata incomplete
Class is being worked on; however, the metadata (including definition) are not complete or sufficiently clear to the branch editors.
Better to represent curation as a process with parts and then relate labels to that process (in IAO meeting)
curation status specification
curation status specification

A phrase describing how a class name should be used. May also include other kinds of examples that facilitate immediate understanding of a class semantics, such as widely known prototypical subclasses or instances of the class.
