The official OBI definition, explaining the meaning of a class or property: &apos;Shall be Aristotelian, formalized and normalized. Can be augmented with colloquial definitions&apos;  is terrible.

Can you fix to something like:

A statement of necessary and sufficient conditions explaining the meaning of an expression referring to a class or property.

Alan Ruttenberg

Your proposed definition is a reasonable candidate, except that it is very common that necessary and sufficient conditions are not given. Mostly they are necessary, occasionally they are necessary and sufficient or just sufficient. Often they use terms that are not themselves defined and so they effectively can&apos;t be evaluated by those criteria. 

On the specifics of the proposed definition:

We don&apos;t have definitions of &apos;meaning&apos; or &apos;expression&apos; or &apos;property&apos;. For &apos;reference&apos; in the intended sense I think we use the term &apos;denotation&apos;. For &apos;expression&apos;, I think we you mean symbol, or identifier. For &apos;meaning&apos; it differs for class and property. For class we want documentation that let&apos;s the intended reader determine whether an entity is instance of the class, or not. For property we want documentation that let&apos;s the intended reader determine, given a pair of potential relata, whether the assertion that the relation holds is true. The &apos;intended reader&apos; part suggests that we also specify who, we expect, would be able to understand the definition, and also generalizes over human and computer reader to include textual and logical definition. 

Personally, I am more comfortable weakening definition to documentation, with instructions as to what is desirable. 

We also have the outstanding issue of how to aim different definitions to different audiences. A clinical audience reading chebi wants a different sort of definition documentation/definition from a chemistry trained audience, and similarly there is a need for a definition that is adequate for an ontologist to work with.</obo:IAO_0000116>

--
From the second IAO workshop, various comments, [commented on by Alan Ruttenberg 8/6/2009]

unit of measure is a quality, e.g. the length of a ruler.

[We decided to hedge on what units of measure are, instead talking about measurement unit labels, which are the information content entities that are about whatever measurement units are. For IAO we need that information entity in any case. See the term measurement unit label]

[Some struggling with the various subflavors of is_about. We subsequently removed the relation represents, and describes until and only when we have a better theory]

a represents b means either a denotes b or a describes

describe:
a describes b means a is about b and a allows an inference of at least one quality of b

We have had a long discussion about denotes versus describes.</obo:IAO_0000116>
        <obo:IAO_0000116 xml:lang="en">From the second IAO workshop: An attempt at tieing the quality to the measurement datum more carefully.

a is a magnitude means a is a determinate quality particular inhering in some bearer b existing at a time t that can be represented/denoted by an information content entity e that has parts denoting a unit of measure, a number, and b. The unit of measure is an instance of the determinable quality.</obo:IAO_0000116>

        <rdfs:comment>Note that this relation was previously called &quot;inheres in&quot;, but was changed to be called &quot;characteristic of&quot; because BFO2 uses &quot;inheres in&quot; in a more restricted fashion. This relation differs from BFO2:inheres_in in two respects: (1) it does not impose a range constraint, and thus it allows qualities of processes, as well as of information entities, whereas BFO2 restricts inheres_in to only apply to independent continuants (2) it is declared functional, i.e. something can only be a characteristic of one thing.</rdfs:comment>

Following we can use this relation to define a further instance-level location relation - not between a continuant and the region which it exactly occupies, but rather between one continuant and another. c is located in c1, in this sense, whenever the spatial region occupied by c is part_of the spatial region occupied by c1.    Note that this relation comprehends both the relation of exact location between one continuant and another which obtains when r and r1 are identical (for example, when a portion of fluid exactly fills a cavity), as well as those sorts of inexact location relations which obtain, for example, between brain and head or between ovum and uterus</obo:IAO_0000116>

        <rdfs:comment xml:lang="en">Despite has characteristic from RO does not have any domain constraints, it is still not possible to directly connect an instance of a process with an instance of a SDC. 

First, SDC is dependent on a IC. As RO does not have &quot;bearer of&quot; object property, the &quot;has characteristic&quot; implies that the domain should be an IC. 

Second, characteristic of is a functional property. Thus, two triples SDC_1 characteristc of IC_1 and SDC_2  characteristc of Process_1 (where IC_1 participates in Process_1), cannot exist simultaneously. 
An example of such case can be &quot;Temperature of during the annealing process was 1000°C&quot;. Temperature is an SDC of some participant of the annealing, however it is not clear whether it is an SDC of an oven or of a sample in the oven. If we assert triple Annealing--&gt; has characteristic --&gt; Temperature 1000°C, then the correct triple connecting temperature SDC with either oven or specimen cannot exist.</rdfs:comment>

The open energy ontology OEO defines portion of matter as a subclass of object aggregate, which implies countability. Our portion is not (precisely) countable and thus bearer of intensive properties.</rdfs:comment>
        <rdfs:comment xml:lang="en">Lome explanation for portion of matter: &quot;What is a molecule cluster at the cellular level? Contrary to the molecular level, at the cellular level of granularity the boundary of each molecule is outside of the level of granular focus. What forms a discontinuous cluster of countable individual molecules and thus bona fide objects at the molecular level, is a continuous and non-countable molecular substance at coarser levels of
granularity. At these coarser levels, the individual molecules cannot be differentiated and demarcated anymore and the cluster as a whole possesses only fiat inner boundaries.&quot;</rdfs:comment>

        <rdfs:comment xml:lang="en">Technical materials are complex object aggregates. The properties that are determined for those object aggregates are intrinsically associated with the methodologies employed in the measurement process. This is in contrast to typical &apos;physical&apos; properties, which like e.g. mass that can be determined to high accuracy independently of the measurement process. 
As a consequence, the behavoiral material properties in the ontology are differeciated according to their measurement method, e.g. Brinell hardness and Vickers hardness are different types of indentation hardness rather than different measures/quantification (GDC) of the materials property &apos;indentation hardness&apos;.
 The &apos;unit idenifieres&apos; of such properties (e.g. &quot;HV1&quot;, &quot;HV10&quot;, &quot;HBW&quot;) are strictly speaking not units but rather references to the measurement methodology used to determine a numeric value that quantifies the property.</rdfs:comment>
        <rdfs:label xml:lang="en">behavioral material property</rdfs:label>
        <skos:definition xml:lang="en">A property is a material trait in terms of the kind and magnitude of response to a specific imposed stimulus. Generally, definitions of properties are made independent of material shape and size.

(Callister, W.D., Rethwisch, D.G., Materials Science and Engineering, Wiley, 2014)

We only deal with intensive (system-size independent) material properties. Extensive properties that depend on the testpiece/specimen/probe size should be found in the respective testing method modules.</skos:definition>
