Metadata value type constants. [@typedef] CGImageMetadataType

The XMP type for a CGImageMetadataTag

CGImageMetadataType defines a list of constants used to indicate the type for a CGImageMetadataTag. If you are reading metadata, use the type to determine how to interpret the CGImageMetadataTag's value. If you are creating a CGImageMetadataTag, use the type to specify how the tag should be serialized in XMP. String types have CFStringRef values, array types have CFArray values, and structure types have CFDictionary values. [@const] kCGImageMetadataTypeDefault The type will be interpretted based on the CFType of the tag's value. This is only used when creating a new CGImageMetadataTag - no existing tags should have this value. CFString defaults to kCGImageMetadataTypeString, CFArray defaults to kCGImageMetadataTypeArrayOrdered, and CFDictionary defaults to kCGImageMetadataTypeStructure. [@const] kCGImageMetadataTypeString A string value. CFNumber and CFBoolean values will be converted to a string. [@const] kCGImageMetadataTypeArrayUnordered An array where order does not matter. Serialized in XMP as . [@const] kCGImageMetadataTypeArrayOrdered An array where order is preserved. Serialized in XMP as . [@const] kCGImageMetadataTypeAlternateArray An ordered array where all elements are alternates for the same value. Serialized in XMP as . [@const] kCGImageMetadataTypeAlternateText A special case of an alternate array where all elements are different localized strings for the same value. Serialized in XMP as an alternate array of strings with xml:lang qualifiers. [@const] kCGImageMetadataTypeStructure A collection of keys and values. Unlike array elements, fields of a structure may belong to different namespaces.
