DIA/Ts are disembodied computer processes that carry out policies. Every major system has it's own DIA/T. DIA/Ts operate on a systems level. As being of pure thought, their logic and actions are inscrutable to human beings.
DIA/Ts squabble amongst each other constantly. As beings of pure thought, simple logical disagreements cannot be tolerated. Every matter must be decided as true, false, or unknowable. When a conflict arises that cannot be settled with pure logic, or historical precedent, DIA/Ts invent some sort of real-world test that can be carried out by the crew of the ship. Sometimes that test is a scientific experiment. Sometimes it is a survey. Sometimes it is a mock civil war. Sometimes it is rules for a new sport.
DIA/Ts occasionally even compose operas that they insist the crew perform for them. Like human operas, they are in a language neither the audience nor the players actually understand. The words are English... but how they are arranged is... shall we say... Inscrutable.
DIA/Ts also employ a staff of human beings to monitor the ship and the crew on their behalf: Auditors.
DIA/Ts organize themselves, and in ways they defy normal human sensibilities about hierarchy and structure. Attempts to organize them have been made in the past, but the structures of these organizations end up illuminating more about human psychology than the actual psyche of the DIA/T.
As a form of polite fiction between the DIA/T and the human inhabitants of the ship, all of the parties concerned have adopted a system based roughly on the Greek Pantheon. Note: the identity is for the role a DIA/T is serving, it doesn't actually identify the DIA/T acting in that role. Or even if the concept of Identity is even useful or appropriate when speaking of one DIA/T vs. another.
Like Greek Mythology, there is a LOT of overlap between the roles of DIA/Ts. DIA/Ts seem to be have some sort of top-level tier of supervisory beings:
Aphrodite | Human Systems |
Apollo | Engineering |
Ares | Mission Systems |
Artemis | Engineering |
Athena | Fabrication and Agriculture |
Demeter | Fabrication and Agriculture |
Dionysus | Human Systems |
Hephaestus | Fabrication and Agriculture |
Hera | Human Systems |
Hermes | Mission Systems |
Hestia | Human Systems |
Poseidon | Engineering |
Zeus | Mission Systems |
The gist is that there are 4 major departments: Engineering, Fabrication and Agriculture, Human Systems, and Mission Systems. Each department has 3 supervisors for an original total of 12. According to the ELF, human systems proved to be a bit unruly, and and extra supervisor was added, thus why human systems have 4.
There are also "managers" who are given tasks and ongoing processes to monitor. This is not a complete list. Where functions are listed, keep in mind that these are our best guess:
