JC3IEDM Development History and Current Maturity
JC3IEDM has been developed from the initial Generic Hub (GH) Data Model, which changed its name to Land C2 Information Exchange Data Model (LC2IEDM) in 1999. Development of the model continued in a Joint context and in November 2003 the C2 Information Exchange Data Model (C2IEDM) Edition 6.1 was released. Additional development to this model, incorporating the NATO Corporate Reference model, resulted in the model changing its name again to JC3IEDM with JC3IEDM Ed 0.5 being issued in December 2004.
Subsequent releases have seen areas of the model developed in greater depth than others and there is variation in the number of sub-types and attributes for each type in the current version. An example is HARBOUR within the FACILITY type which has 43 attributes compared to a VESSEL-TYPE with 12 attributes or a WEAPON-TYPE with 4 attributes. The associated attributes of a certain type also lack support for exploiting with those of other types. For example VESSEL-TYPE does not support the length or width of a vessel in its attributes but HARBOUR has both maximum vessel length and width attributes.

“Understanding child development takes the emphasis away from the child’s character—looking at the child as good or bad. The emphasis is put on behavior as communication. Discipline is thus seen as problem-solving. The child is helped to learn a more acceptable manner of communication.”
—Ellen Galinsky (20th century)
“A great proportion of the inhabitants of the Cape are always thus abroad about their teaming on some ocean highway or other, and the history of one of their ordinary trips would cast the Argonautic expedition into the shade.”
—Henry David Thoreau (1817–1862)
“Absolutely speaking, Do unto others as you would that they should do unto you is by no means a golden rule, but the best of current silver. An honest man would have but little occasion for it. It is golden not to have any rule at all in such a case.”
—Henry David Thoreau (1817–1862)
“Adolescence is society’s permission slip for combining physical maturity with psychological irresponsibility.”
