The tags listed in the following table are to be considered canonical they are described at length in the Exif standard document, and can be found both in the IFD0 and in the IFD1 (some of them, in fact, must be present in both directories). These tags are divided in three categories: canonical, additional and registered to companies. In general, IFD0 and IFD1 can host tags from the same set. Canonical Exif 2.2 and TIFF 6.0 tags for IFD0 and IFD1 The generalities and the reference documents about this structure are introduced in the Structure appendix this section and its subsections list the valid interoperability record tags as well as their format. This standard defines a structure for embedding meta-data in a JPEG picture, to be written in the APP1 segment. The Japan Electronics and Information Technology Industries Association (JEITA) set up a standard for an exchange format for digital still cameras pictures, known as Exif. This document contains a collection of tag tables for JPEG segments it is an appendix to the main manual page of the Image::MetaData::JPEG module, which the reader should refer to for further details and the general scope.
