Information Objects in CSDM are used to represent logical data associated with Business Applications.
They are especially important for governance, compliance, privacy, and audit use cases because they describe the type of data a Business Application processes, stores, or transmits. For example, if an application handles personal data, payment card data, or regulated healthcare information, that logical data context should be modeled as an Information Object and related to the Business Application.
Option A is too broad and incorrectly frames the object as general data for a group of CIs. CIs represent technical components, while Information Objects describe logical business data. Option B is too narrow because API exchange data is only one possible technical integration scenario and does not define the purpose of the CSDM artifact. Therefore, the correct purpose is to describe logical data related to Business Applications.
