However, if the data exists in the form of a track recorded with a GPS device, it makes sense to include the location data as additional metadata in the file.įor these and many other tasks, Phil Harvey has developed ExifTool.
For instance, many digital cameras still do not store location data in the images. In practice, there are exceptions where metadata access is both useful and necessary. Usually, metadata is defined once and then not edited, because it contains important information about the multimedia data. For instance, applications such as Geeqie and digiKam use an image's metadata to control the display order or to narrow a search.
Today, EXIF has other applications and includes far more data than originally intended. Introduced in 2010, EXIF was originally used for digital camera photos. Exchangeable Image File Format (EXIF), the standard for storing this metadata, provides details such as recording date, shutter speed, and aperture, among other things. Multimedia files, such as pictures, videos, or music tracks, often contain metadata (additional information not found in the file name or file attributes).
