Information Entity Ontology Version 1.7 http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology condition described by c condition_described_by p iff p is an instance of a Performance Specification, and p has part d, and d is an instance of a Descriptive Information Content Entity, and p prescribes an entity s, and d describes c, and c is an entity that is causally relevant to s existing as prescribed by p. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology described by x described_by y iff y is an instance of Information Content Entity, and x is an instance of Entity, such that y is about the characteristics by which y can be recognized or visualized. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology It is possible that this relation should be a functional property, that is for all x, y, z if x describes y and x describes z then y = z. For example, if a financial report x describes the quarterly results of a company y and that same financial report describes the quarterly results of a company z, then it should be inferred that companies y and z are the same. We refrained from classifying the relation as a functional property on the concern that descriptions are multifaceted and so consequently it may be that the same report would contain descriptions of multiple entities. describes x describes y iff x is an instance of Information Content Entity, and y is an instance of Entity, such that x is about the characteristics by which y can be recognized or visualized. the content of a newspaper article describes some current event the content of a visitor's log describes some facility visit the content of an accident report describes some accident http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology describes condition p describes_condition c iff p is an instance of a Performance Specification, and p has part d, and d is an instance of a Descriptive Information Content Entity, and p prescribes an entity s, and d describes c, and c is an entity that is causally relevant to s existing as prescribed by p. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology designated by x designated_by y iff y is an instance of Information Content Entity and x is an instance of Entity, such that given some context, y uniquely distinguishes x from other entities. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology designates x designates y iff x is an instance of an Information Content Entity, and y is an instance of an Entity, such that given some context, x uniquely distinguishes y from other entities. a URL designates the location of a Web Page on the internet a person's name designates that person a vehicle identification number designates some vehicle Given a stronger temporal interpretation, this property may be functional.

Calendars typically organize dates through the use of naming and temporal conventions based on Days, Weeks, Months, and Years. https://en.wikipedia.org/w/index.php?title=Cartesian_coordinate_system&oldid=1058613323 http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Cartesian Coordinate System Rectangular Coordinate System A Spatial Reference System that identifies each point in a spatial region of n-dimensions using an ordered n-tuple of numerical coordinates that are the signed (i.e. positive or negative) distances measured in the same unit of length from the zero point where the fixed perpendicular Coordinate System Axes meet. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology In traditional astronomical usage, civil time is mean solar time as calculated from midnight as the beginning of the Civil Day. Note that Civil Time Reference System is more accurately represented as a Temporal Reference System that participates in an act of usage that is sanctioned by an appropriate civil authority. As such, it should be represented as a defined class. Civil Time Reference System A Temporal Reference System that is a statutory time scale as designated by civilian authorities to determine local time(s). http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology A single Clock Time System does not provide a complete means for identifying or measuring times. Depending on the particular Clock Time System, it may be compatible for use with one or more other Temporal Reference Systems. Clock Time System A Temporal Reference System that is a convention for keeping and displaying the Time of Day. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Code Identifier Code ID ID Code Identifier Code A Non-Name Identifier that consists of a string of characters that was created and assigned according to an encoding system such that metadata can be derived from the identifier. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Count Measurement Information Content Entity A Ratio Measurement Information Content Entity that is a measurement of the number of members of some aggregate. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Data Range Interval Estimate Information Content Entity A Ratio Measurement Information Content Entity that is a measurement of a set of values and is equal to the absolute difference between the largest value and the smallest value in the set. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Date Identifier Day Identifier A Temporal Interval Identifier that designates some Day. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Decimal Date Identifier A Date Identifier that designates some Day by using a number to indicate the sequential ordering of the Day since a specified Reference Time. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Decimal Time of Day Identifier Fractional Time of Day Identifier A Time of Day Identifier that designates an approximate Temporal Instant that is part of some Day and is specified using a decimal value for the portion of the Day that preceded the Temporal Instant. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Descriptive Information Content Entity Descriptive ICE An Information Content Entity that consists of a set of propositions that describe some Entity. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Designative Information Content Entity Designative ICE An Information Content Entity that consists of a set of symbols that denote some Entity. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Designative Name Name A Designative Information Content Entity that consists of a string of characters that designates an entity within a specified cultural or social namespace and which is typically a word or phrase in a natural language that has an accepted cultural or social significance. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology 'Deviation Measurement Information Content Entity' and 'Veracity Measurement Information Content Entity' are complementary notions. Deviation is a measure of whether reality conforms to an ICE (e.g., a plan or prediction), whereas Veracity is a measure of whether a Descriptive ICE conforms to reality. Note, the term 'accuracy' is avoided due to its ambiguity between: correctness-of-performance (see: 'Reliability Measurement Information Content Entity'), correctness-of-information (see: 'Veracity Measurement Information Content Entity'), and adherance-to-expectations ('Deviation Measurement Information Content Entity'). Deviation Measurement Information Content Entity Conformance Measurement Degree of Conformance Degree of Deviation Deviation Measurement A Measurement Information Content Entity that is a measurement of the extent to which an entity conforms to how it is expected or supposed to be. a missile impact deviates from its target location by 100 feet a satellite deviaties from its predicted orbital path by 5 kilometers an overweight piece of luggage deviates from an airline's maximum allowed weight by +10 pounds In order for a Deviation to exist, an entity must first be expected, represented, prescribed, or predicted as being a certain way. Then, at a future time, this value can be compared to its actual, reported, or measured value to determine the Deviation between these values. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Diminutive Name An Abbreviated Name that is a familiar form of a Proper Name. Alex, Bob, Cathy "Familiar form of a Proper Name" means: that the name is (originally) a short, affectionate version of the fuller name, used (originally) by family or friends. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Directive Information Content Entity Directive ICE An Information Content Entity that consists of a set of propositions or images (as in the case of a blueprint) that prescribe some Entity. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Distance Measurement Information Content Entity A Ratio Measurement Information Content Entity that is a measurement of a One-Dimensional Extent inhering in some Site that is externally connected to two Independent Continuants. Displacement (vector) is the shortest possible distance (scalar) between two points. Further thought is needed to adequately handle measurements of distance traveled along a path, e.g., a circuitous path or an arc (such as the surface of a planet), versus the simple case of a direct, straight line between two points. Distance is a measure between two reference points, which are located on or in, or in some manner part of, the two obejcts for which the length of the extent between is sought. For exmple, the center point of the indentation of a ball in the sand and the edge of the foul line, the forwardmost point on a car's bumper and the closest point on the 2-dimensional plane that serves as the fiat boundary of a crosswalk, the center of an antenna array and closest point on ground. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Estimate Information Content Entity Estimate Estimate Measurement Information Content Entity Estimated Value A Measurement Information Content Entity that is a measurement of an entity based on partial information about that entity or an appropriately similar entity. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Event Status Nominal Information Content Entity A Nominal Measurement Information Content Entity that is a measurement of the current state of a process. proposed, approved, planned, in progress, completed, failed, or successful http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Geospatial Coordinate Reference System Geographic Coordinate System A Spatial Reference System that is used to determine and identify the location of a point or object at or near the surface of the Earth. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Geospatial Region Bounding Box Identifier List A Measurement Unit of Geocoordinate that is comprised of 4 pairs of coordinates, one for each of the 4 defining points (North, West, South, East) of a Geospatial Region Bounding Box. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Greenwich Mean Time (GMT) is the mean solar time at the Royal Observatory in Greenwich, London and has been superseded by Coordinated Universal Time (UTC). Greenwich Mean Time Zone Identifier A Time Zone Identifier that designates a spatial region where the local time is calculated according to the specified offset from Greenwich Mean Time. http://purl.obolibrary.org/obo/IAO_0000178 http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Information Bearing Entity IBE An Object upon which an Information Content Entity generically depends. http://purl.obolibrary.org/obo/IAO_0000030 http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Information Content Entity ICE A Generically Dependent Continuant that generically depends on some Information Bearing Entity and stands in relation of aboutness to some Entity. Information Content Entity is here intended to be a class of Entities whose instances are the informational content of Information Bearing Entities. For example, three instances of information bearers -- such as a bar chart, color-coded map, and a written report -- each of which lists the GDP of Countries for the year 2010 are each different carriers of the same information content. It is this content that is generically dependent upon its carrier. This treatment of Informational Content Entity (cf. the Information Artifact Ontology) leads to a principle of subtyping based upon the relationship that ICE's have with the Entity they are about rather than characteristics such as format, language, measurement scale, or media. The latter are treated here as being Qualities of bearers. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Typically, an IQE will be a complex pattern made up of multiple qualities joined together spatially. Information Quality Entity IQE A Quality that concretizes some Information Content Entity. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Initialism An Abbreviated Name that consists of the initial letters of some words (or syllables) in a Designative Name, and in which each letter is pronounced separately. USA, CPU, BBC http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Interval Estimate Information Content Entity Interval Estimate Interval Estimate Measurement Information Content Entity An Estimate Information Content Entity that consists of an interval of possible (or probable) values for the measured entity. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Four of the subtypes of measurements used here (Interval, Nominal, Ordinal, and Ratio) were originally defined by S.S. Stevens in the article "On the Theory of Scales of Measurement" in Science, Vol. 103 No. 2684 on June 7, 1946. For an introductory article with links to additional content including criticisms and alternate classifications of measurements see https://en.wikipedia.org/wiki/Level_of_measurement Interval Measurement Information Content Entity A Measurement Information Content Entity that places a Quality of an Entity onto some interval scale having no true zero value.

The Mode is typically most useful when the members of the set are all Nominal Measurement Information Content Entities. Mode Point Estimate Information Content Entity Mode Statistical Mode A Point Estimate Information Content Entity that is a measurement of a set of values and is equal to the value or values that occur most often in the set. https://en.wikipedia.org/w/index.php?title=Natural_language&oldid=1060890461 http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Natural Language A Language that is developed and evolves through use and repetition, rather than through conscious planning or premeditation.

Predictive Information Content Entity Prediction Prediction Information Content Entity A Descriptive Information Content Entity that describes an uncertain future event. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Priority Measurement Information Content Entity Criticality Measurement Importance Measurement Priority Measurement An Ordinal Measurement Information Content Entity that is a measurement of the relative importance of an entity. low, normal, high, urgent, or immediate priority http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Priority Scale A Reference System that is designed to be used to rank or identify the importance of entities of the specified type. https://en.wikipedia.org/w/index.php?title=Probability&oldid=1059657543 http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Every probability measurement is made within a particular context given certain background assumptions. Probability Measurement Information Content Entity Likelihood Measurement Probability Measurement A Measurement Information Content Entity that is a measurement of the likelihood that a Process or Process Aggregate occurs. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Proper Name A Designative Name that is an official name for a particular entity. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology A percentage is one way to express a proportional measure where the decimal expression of the proportion is multiplied by 100, thus giving the proportional value with respect to a whole of 100. E.g., the ratio of pigs to cows on a farm is 44 to 79 (44:79 or 44/79). The proportion of pigs to total animals is 44 to 123 or 44/123. The percentage of pigs is the decimal equivalent of the proportion (0.36) multiplied by a 100 (36%). The percentage can be expressed as a proportion where the numerator value is transformed for a denominator of 100, i.e., 36 of a 100 animals are pigs (36/100). We may want to add either a subclass for Percentage or a data property (has percentage value) that links the percentage expression for a proportion to the relevant IBE. Proportional Ratio Measurement Information Content Entity A Ratio Measurement Information Content Entity that is a measurement of a portion of a whole (described by the numerator) compared against that whole (described by the denominator) where the whole is a nominally described set of like entities. http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology Four of the subtypes of measurements used here (Interval, Nominal, Ordinal, and Ratio) were originally defined by S.S.

International Geomagnetic Reference Field ITRS http://www.ontologyrepository.com/CommonCoreOntologies/Mid/InformationEntityOntology The ITRS definition fulfills the following conditions: 1. It is geocentric, the center of mass being defined for the whole earth, including oceans and atmosphere. 2. The unit of length is the metre (SI). This scale is consistent with the TCG time coordinate for a geocentric local frame, in agreement with IAU and IUGG (1991) resolutions. This is obtained by appropriate relativistic modelling. 3. Its orientation was initially given by the BIH orientation at 1984.0. 4. The time evolution of the orientation is ensured by using a no-net-rotation condition with regards to horizontal tectonic motions over the whole earth.
