Functionality Use case Element Attribute Description of Functionality Change Detailed Functionality (Specification) Coding New The Coding element references a symbol from a defined code system. It uses a code defined in a terminology system to associate semantics with a given term, codelist, variable, or group of variables. The presence of a Coding ODM-6 Done element associates a meaning to its parent element. Coding Nested ItemGroupDef Enhanced Groups of ItemGroups or ItemsDefs, allowing nested structures that can represent a more diverse range of data structures. The revised ItemGroupDef element facilitates a number of new capabilities based on a more flexible re-use of groups of items; for instance, defining enhanced semantics when items share a common relationship or ODM-2 Under Team Review grouping common behaviors such as skip logic or pre-population. ItemGroupDef StudyEventGroupDef New Groups of StudyEventGroups or StudyEvents, allowing nesting ODM-3 Under Team Review of StudyEventGroups. StudyEventGroups are also used to define "study cells", i.e. crossings of epochs and arms.
