#Modeling

Modeling guidance helps implementation teams make decisions that remain understandable when data leaves the originating application and lands in reporting or downstream activation systems.

#Design xAPI profiles

Use profiles to document the statements, verbs, and activity structures your teams expect other systems to interpret consistently.

#Model competencies

Competency data should be explicit about what is being evaluated, how evidence is attached, and which identifiers downstream tools can trust over time.

#Reuse verbs and activity types

Prefer a narrow, deliberate set of verbs and activity types that can be reused across products instead of creating a new semantic surface for every event emitter.
