The party that is the source of something (e.g. a message, shipment, etc.)
comes from agent
This is not the inverse of gist:goesToAgent. A message can be to someone. If we made it the inverse the person would be "from" the message

contributes to
The set of actuators that a controller can affect
directs
A generic ordering relation indicating that the subject comes immediately after the object.
follows directly
It is safest to use this property only when the directness has a semantic correspondence with the world. Only break a direct link by inserting an intermediate item when that change corresponds to a change in the world.
The party that is the recipient of something (e.g. a message, shipment, etc.)
goes to agent
This is not the inverse of gist:comesFromAgent. A message can be from someone. If we made it the inverse the person would be "to" the message
Destination

The subject controls or inhibits the object in some way
governs
Relates the subject to its physical or virtual address.
The street address of a building; the email address of a person.

Relates a living thing to its biological parent.
has biological parent
Relates a Person or Organization to where they can receive messages, including postal addresses, fax numbers, phone numbers, email, web site, etc.
has communication address
Relates a RatioUnit such as meters/second to the denominator Unit (e.g. second).
has denominator
The relationship between a whole and a part where the part has independent existence.
has direct part
It is safest to use this property when there is semantic directness inherent in the relationship, rather than choosing appropriate granularity. For example, a spark plug is a direct part of an engine block; there cannot be any intermediate parts. Beware of making a hasDirectPart assertion and then inserting an intermediate part; this will result in making an asserted triple false even though there was no change in the world.
No cascading delete.
Use this property to directly associate a part with the whole. gist:hasPart is the transitive version.
The subject category is a supercategory of the object category. This property defines the direct links in a category hierarchy; no intermediate categories can exist between the direct links.
has direct subcategory
Unlike its superproperty gist:hasSubCategory, this property is not transitive. It is essentially the same as the non-transitive skos:narrower, using gist:Category rather than skos:Concept.
Immediate child task
has direct sub task
The subject category is a subcategory of the object category. This property defines the direct links in a category hierarchy; no intermediate categories can exist between the direct links.
has direct supercategory
Unlike its superproperty gist:hasSuperCategory, this property is not transitive. It is essentially the same as the non-transitive skos:broader, using gist:Category rather than skos:Concept.

Relates something (e.g. an agreement) to things that play a role, or take part or are otherwise involved in some way.
An event of transferring money has a participating account that receives the money.
has participant
The thing with participants will often be an agreement, event or obligation.
This is intended as an abstract property. Only its subproperties will be directly used.

The subject category is inclusive of, or broader than, the object category. Everything categorized by the subcategory can be inferred to be categorized by the supercategory.
has subcategory
This is essentially the same as skos:narrowerTransitive, using gist:Category instead of skos:Concept.
A task that is part of a larger task. The time frame of the subtasks may overlap but may not extend beyond the time frame of the parent task. A subtask may be part of more than one parent task.
has subtask
The subject category is included by, or narrower than, the object category. Everything categorized by the subcategory can be inferred to be categorized by the supercategory.

This is essentially the same as skos:broaderTransitive, using gist:Category instead of skos:Concept.
Relates a subject category to a unique parent category in an informal (e.g., faceted) hierarchy.

It is safest to use this property when there is semantic directness inherent in the relationship, rather than choosing appropriate granularity. For example, a spark plug is a direct part of an engine block; there cannot be any intermediate parts. Beware of making a directPartOf assertion and then inserting an intermediate part; this will result in making an asserted triple false even though there was no change in the world.

requires
This predicate is defined generally enough to encompass a few different meanings of the English word 'requires':
1. To need something or to make something necessary.
2. To order or demand something, or to order someone to do something, especially because of a rule or law.
3. To make it officially necessary for someone to do something.
Implementations requiring a more specific meaning should define subproperties.

The actual date that something ended, with precision of one day.
'2021-06-01T00:00:00-6:00'^^xsd:dateTime
actual end date
Used for things where the precision of a date is sufficient, such as most projects, tasks, and the like. Recommended usage is to zero out the hours through microseconds to avoid spurious precision.
The actual date and time that something ended, with no implied precision.
actual end date time
This is an abstraction over the various precisions of actual end time, and is not expected to be asserted directly. Values with different precisions can be compared since they all have the same format.
The actual time that something ended, expressed as a system time used for timestamps.
'2021-06-01T08:03:27.12324-6:00'^^xsd:dateTime
actual end microsecond
A system time will be as precise as the system can supply, typically at least milliseconds, sometimes microseconds. The convention for timestamps, such as recording a transaction, is to specify just the end point; the start time is rarely needed.
The actual date and time that something ended, with precision of one minute.
'2021-06-01T08:32:00-6:00'^^xsd:dateTime
actual end minute
Used for things like meetings and time card entries, where the hour and minute are important. Recommended usage is to zero out the seconds and microseconds to avoid spurious precision.
The actual date that something ended, with precision of one year.
'2021-01-01T00:00:00-6:00'^^xsd:dateTime
The tenure of the previous chairman of the board ended in 2021.
actual end year
Used for things where the precision of a year is sufficient. Recommended usage is to zero out the hours through microseconds to avoid spurious precision. Note that it is not valid to zero out months and days, so arbitrary values must be included.
The actual date that something started, with precision of one day.
'2021-06-01T00:00:00-6:00'^^xsd:dateTime
actual start date
Used for things where the precision of a date is sufficient, such as most projects, tasks, and the like. Recommended usage is to zero out the hours through microseconds to avoid spurious precision.
The actual date and time that something ended, with no implied precision.
actual start date time
This is an abstraction over the various precisions of actual start time, and is not expected to be asserted directly. Values with different precisions can be compared since they all have the same format.
The actual time that something started, expressed as a system time used for timestamps.
'2021-06-01T08:03:27.12324-6:00'^^xsd:dateTime
actual start microsecond
A system time will be as precise as the system can supply, typically at least milliseconds, sometimes microseconds. The convention for timestamps, such as recording a transaction, is to specify just the end point; the start time is rarely needed. This property is defined for the cases when you do need to capture the runtime of a system process, and is then used in conjunction with gist:actualEndMicrosecond.
The actual date and time that something started, with precision of one minute.
'2021-06-01T08:32:00-6:00'^^xsd:dateTime
actual start minute
Used for things like meetings and time card entries, where the hour and minute are important. Recommended usage is to zero out the seconds and microseconds to avoid spurious precision.
The actual date that something started, with precision of one year.
'2021-01-01T00:00:00-6:00'^^xsd:dateTime
The tenure of the current chairman of the board began in 2021.
actual start year
Used for things where the precision of a year is sufficient. Recommended usage is to zero out the hours through microseconds to avoid spurious precision. Note that it is not valid to zero out months and days, so arbitrary values must be included.
The date and time at which something did or will occur, with variants for precision, start and end, and actual vs. planned.
at date time
This is the top level property for asserting time, and is not expected to be asserted directly.
The subproperties allow the ontologist to do three things:
1) Distinguish start and end times.
2) Indicate whether a time is planned or actual. This is useful for everything from project management to calendar appointments and the like. It is also useful for date effectivities; i.e., something valid up to a planned date).
3) Distinguish varying levels of precision; sort of a simple version of the Allen functions.
All datetimes are of the same format: '2021-06-01T08:03:27.12324-6:00'^^xsd:dateTime. This is compatible with and a subset of ISO 8601.
Time zone offset, such as -6:00 (of which there are a few dozen) is recognized in the date itself, as shown. The actual time zone standard (of which there are 131) may optionally be attached to the event or other object itself; see property gist:usesTimeZoneStandard.
There will be many historical dates that do not have a time zone offset (e.g., Lincoln's birthday, as well as about 75% of all legacy systems), and in that case the offset can be omitted.
The conventions for precision that are repeated in each property name are as follows:
- *DateTime is an abstraction over the various precisions of its subproperties.
- *Date refers to a calendar date (e.g., birthdays and invoice dates) and is assumed to have precision of one day. Time zone offset is allowed.
- *Minute refers to clock time; e.g., a meeting will start at 9:15 with a timezone offset. Precision is assumed to have precision of one minute.
- *Microsecond refers to system time, and it will be as precise as the system can supply; typically at least milliseconds, sometime microseconds.
The date some living thing was or will be born, with precision of one day.
'2021-06-01T00:00:00-6:00'^^xsd:dateTime
birth date
This is a subproperty of gist:startDateTime rather than gist:actualStartDate because some living things have yet to be born. This property refers to a calendar date and is assumed to precision of one day (time zone offset is allowed). It is recommended to zero out the hours through microseconds to avoid spurious precision. Implementations requiring a birthdate to the minute can define a subproperty.

The conversion factor used to convert a unit to its standard (i.e., coherent) unit (which could be a base unit.)
A value expressed in inches is multiplied by a conversion factor of 0.0254 to express the value in the base unit, meter.
An area expressed as 7 square kilometers is multiplied by a conversion factor of one million which results in 7 million square meters.
conversion factor
Sometimes this property must be used in conjunction with conversionOffset. Kelvin = (Degrees F - conversionOffset) * conversionFactor. Or K = (F-(-469.67)) * (5/9).
Add this number to get to the zero point. On the Celsius scale, the conversionOffset is -273.15 degrees C. On the Fahrenheit scale it is -459.67 degrees. Is equal to 0 when the unit has the same zero point as the base unit. e.g. inch, meter.
conversion offset
The date some living thing died.
'2021-06-01T00:00:00-6:00'^^xsd:dateTime
death date
Refers to a calendar date and is assumed to have precision of one day (time zone offset is allowed). Recommended usage is to zero out the hours through microseconds to avoid spurious precision. Implementations requiring a death date to the minute can define a subproperty.
A statement about someone or something's attributes or characteristics.
The Empire State Building is a 102-story Art Deco skyscraper in Midtown Manhattan in New York City, United States. It was designed by Shreve, Lamb & Harmon and built from 1930 to 1931.

The date and time that something ended.
end date time
This is an abstraction over the various precisions of end time, and is not expected to be asserted directly. Values with different precisions can be compared since they all have the same format.
We have looked at some extreme edge cases (e.g., did this meeting end before or after the trade was posted?) and we couldn't find any use case that required special processing. Those who have such use cases can implement them (and feel free to let us know).
Date that something was posted, not necessarily the date it occurred. Must be after the date of occurrence, but could be before or after the planned date. (Unusual, but I could record today that I expected to be paid last week.)

planned end date
Used for anything with a planned end date, such as when a lease will expire, when an offer is no longer available, etc. Typically a planned date is in the future when first captured, but when tasks run late, we leave the plan where it was and compare it to the actual. Recommended usage is to zero out the hours through microseconds to avoid spurious precision.
The date that something is or was planned to end, with no implied precision.
planned end date time
This is an abstraction over the various precisions of planned end time, and is not expected to be asserted directly. Values with different precisions can be compared since they all have the same format.
This property, unlike gist:actualEndDateTime, does not have a subproperty for microsecond precision, because planned times typically are not expressed at that level of granularity. Typically a planned date is in the future when first captured, but when tasks run late, we leave the plan where it was and compare it to the actual.

planned end year
Used for anything with a planned end date where precision of one year is sufficient. Typically a planned date is in the future when first captured, but when tasks run late, we leave the plan where it was and compare it to the actual.

Tags used in folksonomies; formal definitions from other systems.
Category
Often a 'bucket' can be modeled either as an owl:Class or as a gist:Category. Use the latter if you don't care much about the formal structure of the different types, or if there is a whole hierarchy of types that are going to be managed by a group separate from the ontology developers. The formal structure may be defined elsewhere and linked to, if necessary.

Coherent Unit
Coherent unit is the physics term for this, informally you might think of it as the standard unit for a given dimension.
In principle, the CoherentUnit for a ProductUnit or RatioUnit can be inferred by recursively decomposing the products and ratios into their respective CoherentUnits, bottoming out in SimpleUnits

A bounded region (or set of regions) on the surface of the Earth.
The bounded shape that defines the region occupied by Crater Lake; the bounded area known as the contiguous USA.
Geo Region
A GeoRegion could be non-contiguous; e.g. the region governed by the USA is the region governed by the lower 48 states plus that of Alaska and Hawaii. Child classes in lower ontologies can make this distinction.
A GeoRegion has an area, but it is not itself an instance of the Area class. (Area in gist is a magnitude).

Service Specification
1
Each simple unit has a base unit and a conversion factor to the base. The bases are from the System International (SI). The conversion factor is the number which one multiplies a Unit by to get to base, or divides by to get from base. E.g., the conversionFactor for inch is 0.0254 to get to the base unit (meter).
Simple Unit Of Measure
A set of requirements to be satisfied by a material, design, product, or service.

Street Address
This excludes addresses not associated with a fixed location, such as a PO box or FPO code.
A government of a governed geo-region other than a country, which is under the direct or indirect control of a country government.
Sub-Country Government
Across the world, there are a variety of types of subsections of a country and the governments thereof (as well as different terms, like 'province' and 'state', which refer to essentially the same type of thing). We should not automatically assume 'state', 'county', and 'city'. It is more future-proof just to mint the instances using the generic SubCountryGovernment and, where greater specificity is needed, define categories or subclasses.
Note that the predicate 'governs' is used both for the relationship a government has to a governed geo-region, and for the relationship one government has to the governments of its sub-regions.
This class applies only to organizations governing geo-regions. Regulatory and bureaucratic organizations are members of the more generic GovernmentOrganization class.

Unit of measurement for expressing temperature. Per SI, the base of temperature is in Kelvin, to allow for all units to be expressed relative to a real (in this case absolute) zero.
Temperature Unit
Something used to make instances in its own image. In manufacturing this would be specialized as a die to make stamped parts, cookie cutters are templates for cookies, and forms are templates for data.
A form. A filled-in form has the structure of the form with data entered into some or all of the fields.
