EXIF For a Digital Image Including External Conditions
This vocabulary takes advantage of Exif’s IFD (Image File Directory) to express structured data description. While TIFF 6.0 attribute tags can be regarded as properties of image itself, many of Exif-specific attributes such as flash or fNumber are properties of picture taking condition, and GPS attributes are properties of a location. This vocabulary maps Exif directories to corresponding ‘Image File Data’ classes, and describes those class instances using properties in the IFD. Some tags have integer values whose interpretation are defined in the spec. In this vocabulary, those values are treated as controlled value resource, e.g. ‘#top-left’ instead of integer value ‘1’ for ‘orientation’ tag. more…
