Some metadata-only files may be created from metadata input alone. Here is a list of files that ExifTool can create from scratch: DR4 - Canon DPP version 4 Recipe; EXIF - Exchangeable Image File Format metadata (TIFF-based) EXV - Exiv2 metadata file (JPEG-based) ICC, ICM - International Color Consortium color profile
Exchangeable image file format (officially Exif, according to JEIDA/JEITA/CIPA specifications) [5] is a standard that specifies formats for images, sound, and ancillary tags used by digital cameras (including smartphones), scanners and other systems handling image and sound files recorded by digital cameras.
File verification is the process of using an algorithm for verifying the integrity of a computer file, usually by checksum.This can be done by comparing two files bit-by-bit, but requires two copies of the same file, and may miss systematic corruptions which might occur to both files.

Metadata can be stored either internally, [108] in the same file or structure as the data (this is also called embedded metadata), or externally, in a separate file or field from the described data. A data repository typically stores the metadata detached from the data but can be designed to support embedded metadata approaches.
ID3 is a de facto standard for metadata in MP3 files; no standardization body was involved in its creation nor has such an organization given it a formal approval status. [1] It competes with the APE tag in this area. There are two unrelated versions of ID3: ID3v1 and ID3v2. In ID3v1, the metadata is stored in a 128-byte segment at the end of ...
The XMP Toolkit implements metadata handling in two libraries: XMPCore for creation and manipulation of metadata that follows the XMP Data Model. XMPFiles for embedding serialized metadata in files, and for retrieving embedded metadata. Adobe provides the XMP Toolkit free of charge under a BSD license.
Metadata management goes by the end-to-end process and governance framework for creating, controlling, enhancing, attributing, defining and managing a metadata schema, model or other structured aggregation system, either independently or within a repository and the associated supporting processes (often to enable the management of content).
