    Interface MWGKeywordTags

    MWG (Metadata Working Group) Keywords tags for standardized hierarchical keyword metadata.

    These tags enable consistent keyword organization across different metadata formats (XMP, IPTC, EXIF). ExifTool extracts hierarchical keywords up to 6 levels deep to avoid infinite recursion.

    Note: this is a partial interface: ExifTool extracts more fields from this group type (but I haven't seen those in the wild).

    Properties

    HierarchicalKeywords?: KeywordStruct[]

    Direct array of hierarchical keyword structures.

    Alternative representation providing direct access to keyword tree nodes without the KeywordInfo wrapper. Supports multi-level keyword organization with recursive Children fields.

    KeywordInfo?: KeywordInfoStruct[]

    Array of structured hierarchical keyword information.

    Each entry contains a Hierarchy field with nested KeywordStruct objects representing the complete keyword tree. This is the primary field for accessing full keyword hierarchies.
