Overview
This ontology is a tool for aggregating and consolidating impact accounting data across different standards and vocabularies. The ontology is intended to be generic enough to be used for anthropogenic impact accounting in almost any discipline and context, including climate action impact accounting.
Structure
Our ontology currently comprises 56 classes and 11 primary axioms.

Other
The table below contains terms that were considered for inclusion in the ontology, but for which the decision was made that they were mere synonyms of other classes already included, or they were "terms of convenience" that did not identify specific classes in themselves.
Term | Definition | Synonyms | Notes |
---|---|---|---|
resource | FINAL: A stock or supply of money, materials, staff, and other assets that an agent can use to perform an activity. "[A] stock or supply of money, materials, staff, and other assets that can be drawn on by a person or organization in order to function effectively." (OED, Google) "[A] source of help or information." (OED, Google) "[A]vailable assets." (OED, Google) | A term that can be applied to a thing when it becomes an input or instrument to an activity or process. It is not a class in itself. | |
input | "[W]hat is put in, taken in, or operated on by any process or system." (OED, Google) | Is an attribute of thing:activity and thing:process. A term use to describe the relation of some owl:thing to some owl:activity. It is not a class in itself. | |
output | "[R]esult of a process." (ISO 9000:2015(E)) | result | Is an attribute of thing:activity and thing:process. A term use to describe the relation of some owl:thing to some owl:activity. It is not a class in itself. |
Application of the ontology
TODO: this table is a work in progress and still needs A LOT of work.
Ontology (What are the 'things' that the accounting system should know about? What are the defining properties or characteristics of each 'thing'?) | Epistemology (How will the accounting system get information about these things and their attributes?) | Semiology (How will each of the things be represented in the accounting system?) | |

Agents |
| An agent asserts their identity though digital signatures Agents provide proofs of their properties through verified credentials Other parties can verify agent properties and make claims about their methods and results | Digital signature Verified credentials Validation claim by third party |

Activities |
* An audit is a special type of activity where the input is a claim and the output is an evaluation of that claim. | Ex ante: An agent asserts their intentions to act in a Projet Design Document (PDD) Ex post: An agent describe their actions in a Projet Design Document (PDD) The activity and its results and impacts are documented by the agent at intervals in a monitoring report (MR) |
Consider a token for an activity that contains all the essential elements in column 1. Such a token must have a time limit and proof of life requirements (e.g. minimum process data feed to confirm it is ongoing) IPCC |

States |
*State as in environmental state (not political state) | Parameters/indicators for states Parameters/indicators delivered by agents via PDDs and MRs |

Epistemology
We know about things through direct participation in them or through representations.
For things we experience directly we do not need any further assurance that they are true.
