Details

The Records in Context - Conceptual Model v. 0.2 (preview) Dezember 2019 defines and describes an Activity as follows:
Definition
The doing of something for some human purpose.

Scope Note
Activity is a kind of Event (RiC-E14).
Activity is specifically used to designate purposeful human activity.
Activity may be understood from two perspectives. First it can be understood as leading to an end. The end is the purpose of the Activity, or why the Activity is performed. Second, it can be understood in terms of the processes that lead to achieving the end, how the end is realized through coordinated actions.
Purpose and process are complementary understandings of Activity. Together the two perspectives address why the Activity is performed, the expected ends or outcomes; and
how the Activity fulfills the purpose.
While activity has an intended end, there are also unintended consequences, results not intended, or side-effects. By and large, these may not be the focus of the description, but they are, unquestionably, context.
In a corporate or government context an Activity may also be called a function.
An Activity exists in a specific social and cultural context, and within that context is subject to change over time.
An Activity may be composed of other Activities.
