Is there one word that clearly describes the difference in kind for these four types?

Question

I am stuck on a word choice problem. I have a large amount of response related data, which were previously stored such that each datum lay within one of the following realms:

1. law enforcement
2. health and safety
3. hazardous materials, or
4. other

In order to reduce a significant amount of double entry I have decided to switch the coding so that realm is simply an attribute of each datum. I am also doing this for jurisdiction (e.g., state, local, federal) and some other like attributes that were stored as realms.

My question is, "Is there one word that clearly describes the difference in kind for these four types?"

Any hints well appreciated, as the word choice here will influence the structure of a large number of models based on these data.

The closest I've come so far is vocation, but this seems overly general.

edit 1: each datum denotes a a response action taken such as hospitalization, arrest, or called out (i.e., visited the scene).

edit 2: An example datum might be represented like so:

> {???}: Law Enforcement
   - jurisdiction: Local
        + agency: Police
            * measure: Arrest

While it's clearly tempting to place these into a hierarchy, but I must avoid duplicate entries, so I am trying to encode the agency and allow many different agencies to use the same action.

edit 3: In order to clarify I'll phrase as a simile:

Apples and oranges are to fruits what law enforcement and health/safety are to ...

Answer 1

I would say "Incident Type". If those four zones refer to departments (maybe who responded to it?), you might go with "Incident Responder" or "Incident Department".

Answer 2

I quite like DOMAIN - They look sort of like CIVIC_DEPARTMENTS maybe ??

Answer 3

Would Domain work? (I'm assuming that you don't like "realm" for some reason.)

Edit: another possibility that might fit the edited question better is Agency.

Answer 4

If each denotes a response taken, what about simply result or outcome? Those are general enough to cover any type of response, but convey the meaning of something having been done as a consequence.

Answer 5

"Apples and oranges are to fruit as law enforcement and health/safety are to..."
