ExifTool
ExifTool is a free and open-source software program for reading, writing, and manipulating image, audio, video, and PDF metadata. As such, ExifTool classes as a tag editor. It is platform independent, available as both a Perl library (Image::ExifTool) and a command-line application. ExifTool is commonly incorporated into different types of digital workflows and supports many types of metadata including Exif, IPTC, XMP, JFIF, GeoTIFF, ICC Profile, Photoshop IRB, FlashPix, AFCP and ID3, as well as the manufacturer-specific metadata formats of many digital cameras. This tool is often used in digital forensic analysis and library archival. Metainformation encapsulation ExifTool also implements its own open metadata format. It is designed to encapsulate metainformation from many sources, in binary or textual form, and bundle it together with any type of file. It can either be a single file, wrapping existing data, added as a trailer on other file types, or used as a sidecar fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exif
Exchangeable image file format (officially Exif, according to JEIDA/JEITA/CIPA specifications) 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. The specification uses the following existing encoding formats with the addition of specific metadata tags: JPEG lossy coding for compressed image files, TIFF Rev. 6.0 ( RGB or YCbCr) for uncompressed image files, and RIFF WAV for audio files (linear PCM or ITU-T G.711 μ-law PCM for uncompressed audio data, and IMA-ADPCM for compressed audio data). It does not support JPEG 2000 or GIF encoded images. This standard consists of the Exif image file specification and the Exif audio file specification. Background Exif is supported by almost all digital camera manufacturers. The metadata tags defined in the Exif standard cover a broad spectrum: * Camera settings: This includ ...

Tag Editors
A tag editor is an app that can add, edit, or remove embedded metadata on multimedia file formats. Content creators, such as musicians, photographers, podcasters, and video producers, may need to properly label and manage their creations, adding such details as title, creator, date of creation, and copyright notice. Content creation apps can add metadata to the files they create. Tag editors, however, are apps dedicated to processing metadata, such as DigiKam and MusicBrainz Picard. Their features go beyond manual editing of individual files, offering batch processing and semi-automatic content identification. Audio files editing techniques Manual Media players such as iTunes, Foobar2000 or Winamp, as well as dedicated tag editing programs allow users to manually edit tag and song file information, including composer and release year. Dedicated tag editors may feature batch processing and creating tags from file names and vice versa. Online music databases One type of t ...

Libsndfile
libsndfile is a widely used C library written by Erik de Castro Lopo for reading and writing audio files. It supports a wide variety of audio file formats and will convert automatically from one to another. It allows the programmer to ignore many details, such as endianness. In addition to the library itself, the package provides command-line programs for converting one format to another (sndfile-convert), for playing audio files (sndfile-play), and for obtaining information about the contents of an audio file (sndfile-info). libsndfile is available for Unix-like systems, including Linux and Mac OS X, and for Microsoft Windows. It is licensed under LGPL-2.1-or-later. libsndfile is used, for example, by audio-editing software such as Audacity and Adobe Audition and the MP3 encoder LAME.

Sidecar File
Sidecar files, also known as buddy files or connected files, are computer files that store data (often metadata) which is not supported by the format of a source file. There may be one or more sidecar files for each source file. There may also be "metadata databases" where one database contains metadata for several source files. In most cases the relationship between the source file and the sidecar file is based on the file name; sidecar files have the same base name as the source file, but with a different extension. The problem with this system is that most operating systems and file managers have no knowledge of these relationships, and might allow the user to rename or move one of the files thereby breaking the relationship. Examples ;Amiga Hunk metadata :In AmigaOS, a file with a extension contains metadata for a companion Amiga Hunk executable file. ;Extensible Metadata Platform : Extensible Metadata Platform (XMP) metadata is stored in a sidecar file when either a ...

Extensible Metadata Platform
The Extensible Metadata Platform (XMP) is an ISO standard, originally created by Adobe Systems Inc., for the creation, processing and interchange of standardized and custom metadata for digital documents and data sets. XMP standardizes a data model, a serialization format and core properties for the definition and processing of extensible metadata. It also provides guidelines for embedding XMP information into popular image, video and document file formats, such as JPEG and PDF, without breaking their readability by applications that do not support XMP. Therefore, the non-XMP metadata have to be reconciled with the XMP properties. Although metadata can alternatively be stored in a sidecar file, embedding metadata avoids problems that occur when metadata is stored separately. The XMP data model, serialization format and core properties is published by the International Organization for Standardization as ISO 16684-1:2012 standard. Data model The defined XMP data model can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IPTC Information Interchange Model
The Information Interchange Model (IIM) is a file structure and set of metadata attributes that can be applied to text, images and other media types. It was developed in the early 1990s by the International Press Telecommunications Council (IPTC) to expedite the international exchange of news among newspapers and news agencies. The full IIM specification includes a complex data structure and a set of metadata definitions. A new version of the user guide was released in May 2024. Although IIM was intended for use with all types of news items — including simple text articles — a subset found broad worldwide acceptance as the standard embedded metadata used by news and commercial photographers. Information such as the name of the photographer, copyright information and the caption or other description can be embedded either manually or automatically. IIM metadata embedded in images are often referred to as "IPTC headers", and can be easily encoded and decoded by most p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metadata
Metadata (or metainformation) is "data that provides information about other data", but not the content of the data itself, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, and permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of Statistical data type, statistical data. * Statistical metadata – also called process data, may ...

FlashPix
FlashPix is a bitmapped computer graphics file format where the image is saved in more than one resolution. Its design anticipated that when an HTTP request is sent for the file by a browser plugin implementing the format, only the image compatible with the current screen resolution is returned to the browser, saving on bandwidth and download time. History FlashPix is based on the IVUE file format, the tiled/multi-resolution image file format that was used by the Live Picture software ( Live Picture Inc). In 1995, a consortium of Eastman Kodak (PhotoCD), Microsoft, Hewlett-Packard, and Live Picture Inc were looking for a powerful image file solution, and Live Picture's solution was the best approach for handling large image files. Technical overview FlashPix files have the .fpx file extension. FlashPix uses Microsoft's structured storage format, which stores hierarchical data in a single file. Each image is stored with its sub-resolutions. Each resolution is divided by 2, u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
