Profilscheman

Profilscheman is a concept used in information systems to describe the data schema that defines a user profile. It enumerates attributes such as username, display name, email, avatar URL, account creation date, and user preferences, together with their data types, validation rules, and privacy constraints. The profil schema serves to standardize how profile information is stored, validated, and exchanged between services.

In practice, profilscheman are used in API design, identity management, and data modeling to ensure consistent handling of profile data across applications. The term is common in Dutch- and German-speaking contexts, where it is discussed as part of data governance and interoperability efforts.

A typical profiling schema includes identifiers, contact details, personal attributes, and preference settings. Example fields might be: id (string), username (string), display_name (string), email (string), avatar_url (string), locale (string), created_at (date/time), updated_at (date/time), and a nested preferences object containing privacy and notification settings.

Standards and interoperability: Profil schemas are commonly expressed using JSON Schema, OpenAPI components, GraphQL type definitions, or schema.org vocabulary to enable validation and cross-system compatibility.

Evolution and governance: Changing a profil schema requires versioning, migration strategies, and attention to privacy and data-minimization principles. Backward compatibility and clear deprecation policies are important considerations for long-term maintenance.
