The Statement data structure includes a property for the instructor (context.instructor : Agent) in section 2.4.6.
->
The IEEE standard includes a new context array for contextAgents (in section 4.2.2.5 and section 5.2.2.5). This is an array of contextAgent objects including an objectType, agent and relevantTypes (array of “type” IRIs). Although context.instructor from version 1.0.3 is still present, it is considered deprecated. Implementers should make use of a contextAgent with an instructor relevantType IRI for this purpose. The intent of contextAgent is to allow additional actors to be included as context of a statement beyond just the instructor allowed in version 1.0.3

The Statement data structure includes a property for team (context.team : Group) in section 2.4.6.
->
The IEEE standard includes a new context array for contextGroups (in section 4.2.2.5 and section 5.2.2.5). This is an array of contextGroup objects including an objectType, Group, and relevantTypes (array of “type” IRIs). Although context.team from version 1.0.3 is still present, it is considered deprecated. Implementers should make use of a contextGroup with a team relevantType IRI for this purpose. The intent of contextGroups is to allow additional groups to be included as context of a statement beyond just the team allowed in version 1.0.3
