Struct TagGroup 

pub struct TagGroup {
    pub family0: String,
    pub family1: String,
    pub family2: String,
    pub family3: String,
}

Identifies the metadata group hierarchy (mirrors ExifTool’s Group0..Group3).

Fields

family0: String

Family 0: Information type (EXIF, IPTC, XMP, ICC_Profile, etc.)

family1: String

Family 1: Specific location (IFD0, ExifIFD, GPS, XMP-dc, etc.)

family2: String

Family 2: Category (Image, Camera, Location, Time, Author, etc.)

family3: String

Family 3: Document number (MAIN_DOCUMENT, “Doc1”, “Doc2”, etc.).

Tags read from the file itself belong to the main document. Formats that carry repeated or embedded sub-documents (e.g. the timed messages of a Garmin FIT file under ExtractEmbedded) place each one in its own numbered document, exactly as ExifTool’s -G3 output does.
