8.8 The IDs for Top Level Classes
As mentioned in the previous section, the hierarchy of path elements is of no use for identifying instances of each TLC, given the fact that there can be no unique hierarchy of subclasses in the Akoma Ntoso ontology.
Thus each instance of the ontology needs to be provided with an ID guaranteed to be unique within the TLC it belongs to. The syntax of the ID depends on the actual TLC, and is briefly explained in the following schema.
8.8.1 TLC Person
A dot-separated string composed of the country of citizenship, the first name, the family name, the birth date in yyyy-mm-dd format, and an optional arbitrary string if ambiguity exists (e.g., if two individuals with the same name and the same birth date exist in the same country).
- kn.joe.smith.1964-12-22
Mr. Joe Smith, the only Kenyan citizen with that name born on December 22nd, 1964
8.8.2 TLC Organization
A dot-separated string composed of the country of registration (or the string “int” if international, or the string “unreg” if not registered anywhere), a recognizable form of the organization name and an optional arbitrary string if ambiguity exists (e.g., if two organizations with the same name exist in the same country).
- kn.parliament
the Kenyan Parliament
8.8.3 TLC Concept
Concepts differ from terms as they are referring to a specific word or collection of words embodying some concept, rather than to the concept embodied by different words. Therefore, for instance, pope and pontiff are different terms for the same concept, while date is a single term referring to two different concepts (a calendar date as opposed to a type of fruit). Concepts must refer to an specific reference resource that can be used to disambiguate the object being referred to. This must be either a thesaurus, an encyclopedia or a commonly available dictionary. A unique form of the terms specifying the concept joined with dots preceded by an unambiguous name for the resource being used. No country specifications are necessary for concepts.

8.8.4 TLC Object
Objects must refer to a specific reference resource that can be used to disambiguate the object being referred to. This must be either a thesaurus, an encyclopedia or a commonly available dictionary.

8.8.6 TLC Place
Places must refer to a specific reference resource that can be used to disambiguate the object being referred to. This must be either a thesaurus, an encyclopedia or a commonly available dictionary.

Country specifications are necessary for processes since processes with the same name may exist with different steps across different countries.

8.8.8 TLC Role

A unique form of the terms specifying the concept joined with dots preceded by an unambiguous name for the resource being used. Country specifications are necessary for roles since roles with the same name may exist with different characteristics across different countries.

8.8.9 TLC Term
Terms differ from concepts as they are referring to a specific word or collection of words embodying some concept, rather than to the concept embodied by different words. Therefore, for instance, pope and pontiff are different terms for the same concept, while date is a single terms referring to two different concepts (a calendar date as opposed to a type of fruit). Terms must refer to a specific reference resource that can be used to disambiguate the object being referred to. This must be either a thesaurus, an encyclopedia or a commonly available dictionary.
