ExifTool
ExifTool meta information reader/writer
ExifTool is a battle-tested Perl application for reading, writing, and batch-editing metadata in thousands of file types—images, videos, audio, documents, and more. It understands major standards like EXIF, IPTC, and XMP as well as an enormous range of camera maker notes and container formats (for example, QuickTime/MP4, PDF, TIFF). Typical workflows include extracting metadata to JSON/CSV/XML, renaming files from timestamps or tags, shifting capture times, copying tags between files, and cleaning or normalizing fields for archives. The tool is meticulous about character encodings, time zones, and tag groups, helping avoid silent corruption when moving metadata between ecosystems. It is scriptable and composable, with options to operate recursively, write sidecars, preserve originals, or do dry runs for safety. Professionals rely on ExifTool for digital asset management, forensic workflows, and any pipeline where metadata quality and traceability matter. -

Amazon EC2 Metadata Mock
A tool to simulate Amazon EC2 instance metadata
Instance metadata is data about your instance that you can use to configure or manage the running instance. Instance metadata is divided into categories, for example, hostname, events, and security groups. You can also use instance metadata to access user data that you specified when launching your instance. For example, you can specify parameters for configuring your instance, or include a simple script. You can build generic AMIs and use user data to modify the configuration files supplied at launch time. For example, if you run web servers for various small businesses, they can all use the same generic AMI and retrieve their content from the Amazon S3 bucket that you specify in the user data at launch. To add a new customer at any time, create a bucket for the customer, add their content, and launch your AMI with the unique bucket name provided to your code in the user data. If you launch more than one instance at the same time, the user data is available to all instances. -
