"An entity is a physical, digital, conceptual, or other kind of thing with some fixed aspects; entities may be real or imaginary." (https://www.w3.org/ns/prov#Entity)

A thing that bears some form of accountability for the occurrence of another thing.

A thing that bears some form of responsibility for an activity or for the existence of another thing, and which can be held accountable for it.

"An agent is something that bears some form of responsibility for an activity taking place, for the existence of an entity, or for another agent's activity." (http://www.w3.org/ns/prov#Agent)

"[A] person or thing that takes an active role or produces a specified effect." (OED, Google)

"[The] doer of an action, typically expressed as the subject of an active verb or in a by phrase with a passive verb." (OED, Google)

"occurrence" = happening or existing.

'organization' as defined in ISO's Annex SL Appendix 2 is treated in this ontology as an agent consisting of multiple other agents.

Think further about delegation.

A quality or feature of a thing that can be used, whether independently or in conjunction with other attributes, to identify it.

"[A] quality or feature regarded as a characteristic or inherent part of someone or something." (OED, Google)

An attribute is something that is expected to remain constant for the duration of the impact accounting exercise. It is typically not related to scope or extent.

"[A] distinctive attribute or aspect of something." ("feature" ~ OED, Google)

"[A] feature or quality belonging typically to a person, place, or thing and serving to identify them." ("characteristic" ~ OED, Google)

"[A]n assertion that something is true." (OED, Google)

2024/10/15 

A formal statement made by an agent in which they claim to have witnessed or been presented with sufficient evidence to consider a specific claim made by another agent as truthful or accurate.

"[A] declaration that something exists or is the case." (OED, Google)

attest(v): "[P]rovide or serve as clear evidence of." (OED, Google)

Can be be based on measurement or calculation.

Re 'state' vs 'status:

https://english.stackexchange.com/questions/12958/status-vs-state

'state' usually refers to a condition that can fluctuate along a spectrum, while 'status' usually refers to a condition that can only progress (move in one direction only) along a linear, usually discrete, scale.

2024/11/17

A thing that limits or directs another thing.

A means of limiting or directing a thing.

"[A] means of limiting or regulating something." (OED, Google)

"[T]he restriction of an activity, tendency, or phenomenon." (OED, Google)

limit, regulation, constraint, guide(n),

directive, specification,

requirement,

constraint

An impact accounting standard is a control that comprises both procedures and object specifications.

"standard": {

1. "[A] level of quality or attainment." (OED, Google)
2. "[A] required or agreed level of quality or attainment." (OED, Google)
3. "[S]omething used as a measure, norm, or model in comparative evaluations." (OED, Google)
4. "[P]rinciples of conduct informed by notions of honour and decency." (OED, Google)

}

requirement: {

1. "[A] thing that is needed or wanted." (OED, Google)
2. "[A] thing that is compulsory; a necessary condition." (OED, Google)
3. "[N]eed or expectation that is stated, generally implied or obligatory." (ISO Annex SL Appendix 2)

}

constraint: {

1. "[A] limitation or restriction." (OED, Google)
2. "[S]omething that controls what you do by keeping you within particular limits." (Cambridge)
3. "[A] constraining condition, agency, or force." (Merriam-Webster)
4. "[A] restrictive condition." (Collins)

}

A procedure guides an activity.

procedure: {

1. "[A]n established or official way of doing something." (OED, Google)
2. "[A] series of actions conducted in a certain order or manner." (OED, Google)
3. "[S]pecified way to carry out an activity or process." (ISO 9000:2015(E))

}

"methodology": {

1. "[A] system of methods used in a particular area of study or activity." (OED, Google)

}

Methodology vs. procedure: {

1. Option 1: "methodology" is a synonym for "procedure".
2. Option 2: A methodology is a subclass of a procedure; hence narrower as a procedure.
3. Option 3: A methodology is a thing:control that simply contains a procedure. 

}

An object specification is a control.

"[D]ocument stating requirements." ("specification", ISO 9000:2015(E))

"A plan is an entity that represents a set of actions or steps intended by one or more agents to achieve some goals." (http://www.w3.org/ns/prov#Plan)

A condition limits an activity with reference to a state.

"Condition" in the sense of "if x then..." are expressed by using thing:state inside thing:control. Definitions for "condition": {

1. "[A] situation that must exist before something else is possible or permitted." (OED, Google)
2. "[A]n arrangement that must exist before something else can happen." (Cambridge)
3. "[A] premise upon which the fulfillment of an agreement depends." (Merriam-Webster)

2024/10/15

A system for organising things into groups according to their attributes.

2024/10/15

A defined structure and encoding system for the processing, storage, or presentation of data.

#AH: I don't think we need this in version 1 of AIAO. A format is not a control per se; a control can specify what the format of something should be, but that control is not a format - it is a specification for a format. "format" falls, to my mind, in the same category as "colour" - it's not a control but an attribute or property that can be controlled.

Format: encoding system [text, images, audio, sensor data,)

A control that guides a mathematical calculation.

"[A] method or procedure for achieving something." (OED, Google)

"[A] mathematical relationship or rule expressed in symbols." (OED, Google)

2024/10/15

"[A] widespread belief that someone or something has a particular characteristic." (OED, Google)

A system for expressing and comparing quantities.

A system for expressing states related to quantity, scale or rank.

A measurement system allows the expression of the state of a parameter.

datum

system of measurement

I.e., a system for answering the question of "How much?"

A measurement system standardises units for measuring and comparing quantities.

A spatial reference system sets standards for determining and comparing locations. A spatial reference system defines points of reference and standardises methods for describing the location of things relative to those points of reference.

Example 1: What Three Words is a spatial reference system, not a measurement system.

Example 2: The statements "300 miles south of the equator" and "482 kilometers south of the equator" make use of the same spatial reference system, but different measurement systems.

A desired state to be effected by an activity.

"[R]esult to be achieved." (ISO Annex SL Appendix 2)

A limit or boundary wich defines the scope or extent of an environment, event, or process.

A quality or feature forming one of a set that defines a thing or sets the conditions of its existence or operation.

"[A] limit or boundary which defines the scope of a particular process or activity." (OED, Google)

"[A] numerical or other measurable factor forming one of a set that defines a system or sets the conditions of its operation." (OED, Google)

"[A] numerical characteristic of a population, as distinct from a statistic of a sample." (OED, Google)

"[A] standard unit used to express the size, amount, or degree of something." ("measure" ~ OED, Google)

Whether a thing is an attribute, an indicator or a parameter depends on its purpose during the impact accounting exercise and whether its value will remain constant or not during the impact accounting exercise.

If the value of an indicator or a parameter will remain fixed during impact accounting exercise and can consequently be used to distinguish the bearer thereof from other individuals with different values for that indicator or parameter, the indicator or parameter acts as an attribute and should be treated as such. 

If the value of a parameter can vary during the impact accounting exercise, but its variability is neither caused by the activity under study, nor affects the impact of the activity under study, then the parameter should simply be treated as a parameter.

If the value of a parameter can vary during the impact accounting exercise, and its variability is caused by the activity, then the parameter should rather be considered an indicator.

A parameter wich defines the spatial scope or spatial extent of an environment, an event, or a process.

2024/10/15

The amount of space that a thing occupies.

"[T]he size or scale of something." (OED, Google)

"[T]he degree or limit of something; how great or severe something is." (Cambridge Dictionary)

"[T]he amount of space or surface that something occupies or the distance over which it extends." (Merriam-Webster)

"[T]he range over which something extends." (Merriam-Webster)

"[T]he space, amount, or degree to which a thing extends; size; length; breadth." (Collins)

Multiple sets of coordinates.

"extent" is embedded in the very definition of "parameter".

2024/11/14

The amount of space that a thing occupies across two spatial dimensions, expressed according to a spatial measurement system.

This is an individual of the class 'spatial parameter', not a subclass of class 'spatial parameter'.

The amount of space that a thing occupies in a single spatial dimension, expressed according to a spatial measurement system.

This is an individual of the class 'spatial parameter', not a subclass of class 'spatial parameter'.

Length, widht and height is each an example.

2024/10/15

The amount of space that a thing occupies across three spatial dimensions, expressed according to a spatial measurement system.

This is an individual of the class 'spatial parameter', not a subclass of class 'spatial parameter'.

The point in space at which a thing occurs, expressed according to a spatial reference system.

Location, or space, can - like time and periods - be either definite or fuzzy.

This is an individual of the class 'spatial parameter', not a subclass of class 'spatial parameter'.

Is this not rather an attribute or an indicator?

The relation between the spatial locations of different parts of a thing.

The locations of the parts of a thing relative to each other.

The arrangement of a thing in space.

"[A] particular way in which someone or something is placed or arranged." (OED, Google)

"[A] certain arrangement of bodily parts." (Merriam-Webster)

"[T]he way in which something is arranged." (Cambridge Dictionary)

"[T]he way in which someone is lying, sitting, or standing." (Cambridge Dictionary)

This is an individual of the class 'spatial parameter', not a subclass of class 'spatial parameter'.

Is this not rather an attribute or an indicator?

A parameter wich defines the temporal scope or temporal extent of an environment, an event, or a process.

2024/10/15

The amount of time that a thing occupies, expressed according to a temporal measurement system.

"[T]he time during which something continues." (OED, Google)

"Duration of a temporal extent expressed as a decimal number scaled by a temporal unit." (owl-time)

The point in time at which a thing occurs, expressed according to a temporal reference system.

"[A] precise moment of time." ("instant" - OED, Google)

"[A]n exact point in time." ("moment" - OED, Google)

"A temporal entity with zero extent or duration." (owl-time) It could have location, though, because "...properties ...provide alternative ways to describe the temporal position of an :Instant." (owl-time)

An extent of time between two (thing:parameter:temporal_parameter:)instants.

An extent of time of which the start and end is each marked by a specific (thing:parameter:temporal_parameter:)instance

An extent of time defined by a specific starting instant and a specific ending instant.

"A temporal entity with non-zero extent or duration, i.e. for which the value of the beginning and end are different." ("proper interval", owl-time)

a length or portion of time

A portion of time defined by a specific starting point in time and a specific ending point in time.

Some periods in time may be "fuzzy" - exact y:m:d h:m:s may be unknown, but we can attribute a starting or ending point with a certain level of confidence. I.e., they can be definite or fuzzy.

This is an individual of the class 'spatial parameter', not a subclass of class 'spatial parameter'.

"A temporal position described using either a (nominal) value from an ordinal reference system, or a (numeric) value in a temporal coordinate system." ("time position", owl-time)

"A position on a time-line" ("temporal position", owl-time)

E.g., "travel through space and time"

#AH: We distinguish between 'position' and 'location' when we talk about space, so we should probably not conflate the two terms when we talk about time. The Time Ontology's definitions of "time position" and "temporal position" each conflates "position" and "location", in my opinion.

2024/10/16

A control that specifies the scope of and/or requirements for an agent's relation to an event.

A predefined set of requirements, responsibilities and/or actions for an agent with regard to a specific activity.

The function assumed or part enacted by an agent in a particular situation, and which might be subjected to a thing:control.

"[T]he function assumed or part played by a person or thing in a particular situation." (OED, Google)

"[A] role is particular behaviour which a material entity may exhibit."

CHEBI:50906

"A role is the function of an entity or agent with respect to an activity, in the context of a usage, generation, invalidation, association, start, and end." (http://www.w3.org/ns/prov#Role)

Roles are context-specific.
A role restricts the set of activities that an agent can perform in the context within which they enact the role.
Roles are sometimes mutually exclusive.
Some roles require the enacting agent to have met certain requirements to be allowed to enact the role in that context.

Cf. 4E cognition: embodied, embedded, enactive, extended.

Define 'responsibility'?

Add 'requirement' to the definition? Define 'requirement'?

Is this not an individual of class 'control' rather than a subclass thereof?

A predefined set of responsibilities and actions for an agent who defines and prepares the conditions for an activity or a set of activities.

"[A] person or thing that develops something." (OED, Google)

#AH: Do we need this? In an impact accounting scenario the project developer is really just a service provider to the owner of the project in question. It is ultimately the owner of the project who will be held accountable for the impact of the project, not the project developer, so do we really need to single the role of "project developer" out?

A predefined set of requirements, responsibilities and/or actions for an agent who verifies a claim.

"[S]omeone who vouches for another or for the correctness of a statement." ("verifier")

A predefined set of requirements, responsibilities and/or actions for an agent who conducts an audit.

I.e., a system for answering the question of "Where?"

A measurement system standardises units for measuring and comparing quantities.

A spatial reference system sets standards for determining and comparing locations. A spatial reference system defines points of reference and standardises methods for describing the location of things relative to those points of reference.

Example 1: What Three Words is a spatial reference system, not a measurement system.

Example 2: The statements "300 miles south of the equator" and "482 kilometers south of the equator" make use of the same spatial reference system, but different measurement systems.

Location can be either an attribute or a state, depending on the context.

Has a spatial dimension.

"Events include generation, usage, or invalidation of entities, as well as starting or ending of activities...

An... event... happens in the world and marks a change in the world, in its activities and in its entities. The term 'event' is commonly used in process algebra with a similar meaning. Events represent communications or interactions; they are assumed to be atomic and instantaneous." (http://www.w3.org/ns/prov#InstantaneousEvent)

"orchestrate": "[P]lan or coordinate the elements of (a situation) to produce a desired effect..." (OED, Google)

The only activities we are concerned with defining are the ones in which humans are in some accountable way involved in the execution thereof. If the activity cannot be used in the sentence "An agent engages in (a/an) <the activity>", then we are not concerned with defining it.

2024/10/15

The activity of deriving the value of a parameter or indicator from one or more other values, according to some mathematical calculation formula. (Cf. thing:event:activity:measuring.)

2024/10/15

There's the event of the activity, and then there's the event of the

state change caused by the activity on

some environment.

It only becomes an impact once it is explicitly associated with an agent or an activity as its cause.

A thing presented in support of the truthfulness of a claim.

"[T]he available body of facts or information indicating whether a belief or proposition is true or valid."

"[I]nformation drawn from personal testimony, a document, or a material object, used to establish facts in a legal investigation or admissible as testimony in a law court."

"[S]igns or indications of something."

Evidence can be physical (e.g., the presence of some material) or in the form of sworn statements (affidavits, witness accounts) by other agents.

A thing is never a substantiation in itself, as e.g., an agent or an activity or an instrument is a thing in itself. When a thing is presented as a substantiation to a claim, the connection between that thing and the claim is best expressed as a relationship.

A thing used to perform an activity, but which does not undergo a significant state change due to the activity.

(as opposed to consumables that do undergo significant state changes due to the activity)

A thing used to perform an activity. 

A thing used during the performance of an activity, and which neither forms part of the consumable inputs to the activity, nor forms part of the intended output of the activity.
