subfieldsfor

subfieldsfor is a term used in metadata schema design and templating to denote a function or convention that retrieves the subfields related to a given parent field or record type. It is commonly encountered in wiki software, content-management templates, and data editors that support dynamic form generation or data traversal.

Definition and concept

In schema terms, subfieldsfor(F) returns the list of fields defined as subfields under the parent field F. The function is descriptive rather than a formal programming keyword, and its exact behavior can vary by implementation. It is typically used to aid schema exploration, form generation, and data validation.

Usage

In a template or schema-aware editor, a directive like subfieldsfor("Book") might yield a list such as ["Title", "Author", "ISBN", "PublicationDate"], guiding the construction of an editing form or display template. It can also support data validation by constraining inputs to the subfields permitted for a given parent type.

Examples

Within a wiki infobox system, subfieldsfor("Event") could return ["Date", "Location", "Sponsor"]. In a JSON schema explorer, a similar concept helps reveal nested properties under a parent object for user navigation.

Relation to other concepts

subfieldsfor is related to field hierarchies, schema introspection, and metadata management. It is not a universal programming keyword; support depends on the specific platform or templating system being used.

Notes

The term is informal and context-dependent, used primarily in documentation and project-specific workflows rather than as a standardized feature.
