Overview of the MAEC Data Models for MAEC Version 4.1

Version 4.1 of the MAEC Language is defined by three data models, each of which is implemented in its own XML schema. There is also a default vocabularies schema, which defines a default set of controlled vocabularies used within MAEC.

As illustrated, “MAEC Bundle” is the (lowest) Tier 1 data model; “MAEC Package” is the (middle) Tier 2 data model; and “MAEC Container” is the (highest) Tier 3 data model. All three data models offer a stand-alone output format, so a lower level model can be used without the higher tier data model (although each model level requires all lower tiers). This three-tiered structure provides flexibility in the type and amount of information that can be shared.
