  intersection of: Restriction
    on property: is governed by
    some values from: Country Government
definition: A government of a governed geo-region other than a country, which is under the direct or indirect control of a country government.
scope note: 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.
scope note: 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.

sub property of: actual end date time
definition: The actual date that something ended, with precision of one day.
example: '2021-06-01T00:00:00-6:00'^^xsd:dateTime
scope note: 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.

actual end date time
type: DatatypeProperty
range: dateTime
sub property of: end date time
definition: The actual date and time that something ended, with no implied precision.
scope note: 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.

actual end microsecond
type: DatatypeProperty
range: dateTime
sub property of: actual end date time
definition: The actual time that something ended, expressed as a system time used for timestamps.
example: '2021-06-01T08:03:27.12324-6:00'^^xsd:dateTime
scope note: 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.

actual end minute
type: DatatypeProperty
range: dateTime
sub property of: actual end date time
definition: The actual date and time that something ended, with precision of one minute.
example: '2021-06-01T08:32:00-6:00'^^xsd:dateTime

sub property of: actual end date time
definition: The actual date that something ended, with precision of one year.
example: '2021-01-01T00:00:00-6:00'^^xsd:dateTime
example: The tenure of the previous chairman of the board ended in 2021.
scope note: 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.

actual start date
type: DatatypeProperty
range: dateTime
sub property of: actual start date time
definition: The actual date that something started, with precision of one day.
example: '2021-06-01T00:00:00-6:00'^^xsd:dateTime

actual start microsecond
type: DatatypeProperty
range: dateTime
sub property of: actual start date time
definition: The actual time that something started, expressed as a system time used for timestamps.
example: '2021-06-01T08:03:27.12324-6:00'^^xsd:dateTime
scope note: 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.

actual start minute
type: DatatypeProperty
range: dateTime
sub property of: actual start date time
definition: The actual date and time that something started, with precision of one minute.
example: '2021-06-01T08:32:00-6:00'^^xsd:dateTime
scope note: 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.

actual start year
type: DatatypeProperty
range: dateTime
sub property of: actual start date time
definition: The actual date that something started, with precision of one year.
example: '2021-01-01T00:00:00-6:00'^^xsd:dateTime
example: The tenure of the current chairman of the board began in 2021.
scope note: 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.

at date time
type: DatatypeProperty
range: dateTime
definition: The date and time at which something did or will occur, with variants for precision, start and end, and actual vs. planned.
scope note: 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.

birth date
type: DatatypeProperty
range: dateTime
sub property of: start date time
definition: The date some living thing was or will be born, with precision of one day.
example: '2021-06-01T00:00:00-6:00'^^xsd:dateTime
scope note: 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.

  union of: Person
sub property of: has participant
definition: The party that is the source of something (e.g. a message, shipment, etc.)

example: A value expressed in inches is multiplied by a conversion factor of 0.0254 to express the value in the base unit, meter.
example: An area expressed as 7 square kilometers is multiplied by a conversion factor of one million which results in 7 million square meters.
scope note: Sometimes this property must be used in conjunction with conversionOffset. Kelvin = (Degrees F - conversionOffset) * conversionFactor. Or K = (F-(-469.67)) * (5/9).

conversion offset
type: DatatypeProperty
domain: Unit of Measure
range: double
definition: 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.

range: string
sub property of: contained text
definition: Links to the string corresponding to EncryptedText

end date time
type: DatatypeProperty
range: dateTime
sub property of: at date time
definition: The date and time that something ended.
scope note: 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.
scope note: 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).

follows directly
type: ObjectProperty
inverse of: precedes directly
definition: A generic ordering relation indicating that the subject comes immediately after the object.

type: ObjectProperty
range: Class
  union of: Organization
  union of: Person
sub property of: has participant
definition: The party that is the recipient of something (e.g. a message, shipment, etc.)

scope note: 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.
scope note: No cascading delete.

Recommended usage is to zero out the seconds and microseconds to avoid spurious precision.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
type: DatatypeProperty
range: dateTime
sub property of: planned end date time
definition: The date that something is or was planned to end, with precision of one year.
example: '2021-01-01T00:00:00-6:00'^^xsd:dateTime
example: The automobile manufacturer announced that it will stop producing gas-powered vehicles in 2035.
scope note: 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. 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.

planned start date
type: DatatypeProperty
range: dateTime
sub property of: planned start date time
definition: The date that something is or was planned to start, with precision of one day.
example: '2021-06-01T00:00:00-6:00'^^xsd:dateTime

Recommended usage is to zero out the hours through microseconds to avoid spurious precision.

planned start date time
type: DatatypeProperty
range: dateTime
sub property of: start date time
definition: The date and time that something is or was planned to start, with no implied precision.
scope note: This is an abstraction over the various precisions of planned start time, and is not expected to be asserted directly. Values with different precisions can be compared since they all have the same format.
scope note: This property, unlike gist:actualStartDateTime, 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.

type: DatatypeProperty
range: dateTime
sub property of: planned start date time
definition: The date and time that something is or was planned to start, with precision of one minute.

sub property of: planned start date time
definition: The date that something is or was planned to start, with precision of one year.
example: '2021-01-01T00:00:00-6:00'^^xsd:dateTime
example: The automobile manufacturer announced that its full line-up will include only electric cars starting in 2035.
scope note: Used for anything with a planned start 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. 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.
