ExifTool for Efficient Metadata Editing
ExifTool by Phil Harvey is a versatile and platform-independent tool that functions as both a Perl library and a command-line application. It allows users to read, write, and edit metadata in a diverse range of file types. Its extensive capabilities make it an indispensable resource for anyone working with file information management.
As system administrators, we need to make it a habit to regularly check our files. This helps us confirm that the metadata for our digital assets is accurate and meets our storage and cataloging standards. Using batch processing can be a game-changer, allowing us to efficiently update and correct metadata for multiple files at once—it’s especially handy when dealing with large collections of media. It’s also important to monitor file ownership. By investigating who created the files, when they were modified, and their version history, we can troubleshoot issues more effectively and manage rights properly. Finally, we can’t underestimate the importance of maintaining backups. They ensure that we retain crucial metadata during file transfers and while backing up our data, protecting us from potential data loss and helping us with disaster recovery when needed.
