Extensible Metadata Platform (XMP) parser extracts metadata from JPEG and TIFF image files. It also supports parsing raw XML files containing XMP.

A Ruby library for prying open files you can convert to a previewable format, such as video, image and audio files. It includes a number of parser modules that try to recover metadata useful for post-processing and layout while reading the absolute minimum amount of data possible.

MMS2R is a library that decodes the parts of a MMS message to disk while stripping out advertising injected by the mobile carriers.

Command-line tool that automatises photo/video uploads to Flickr. Entering 'flickru <directory>' in your command line, any photos under 'directory' (and subdirs) are uploaded to your Flickr account (interactively entered the first time you start flickru). Photos are identified by case-insensitive extensions: GIF, JPEG, JPG, PNG, and TIFF. Videos are identified by case-insensitive extensions: AVI, MPEG, and MPG. flickru automatically sets the following Flickr metadata: (1) date taken: file last-modification time, unless JPEG/TIFF Exif metadatum 'date_time_original' is found (Flickr understands it natively). (2) privacy policy: private, visible by friends & family, hidden for public searches (3) safety level: safe (4) permissions: friends & family can add comments to the photo and its notes; nobody can add notes and tags to the photo (5) description: for videos longer than 90s (Flickr's longest allowed duration) but shorter than 500MB (Flickr's maximum permisible size), it will contain an annotation about its large duration. (6) title: extracted from the parent directory name (7) geolocation & accuracy: extracted from the parent directory name, unless JPEG/TIFF Exif GPS metadata is found (Flickr understands them natively). Before uploading photos, please, make sure that you have correctly named each photos parent directory according to the name format 'TITLE[@LOCATION[#PRECISION]]', where: (1) TITLE is the desired title for the photos stored in the directory. If no LOCATION is given, flickru tries to extract the location from Wikipedia page TITLE. (2) LOCATION is the location of the photos, specified as: (a) the Wikipedia page name (whitespaces allowed) of the location or (b) its coordinates LATITUDE,LONGITUDE (3) PRECISION is the Flickr geolocation precision. Flickru sets it to one of the following case insentitive literals: 'street', 'city', 'region', 'country', 'world'. Photos are classified into photosets. If the photoset does not exist, flickru creates it. This photoset is named after its grandparent directory. The photoset is arranged by 'date taken' (older first). To see some examples on the directory structure recognised by flickru, please explore the subdirectories under 'var/ts'.

A command line application that recursively reads all of the images from the supplied directory of images, extracts their EXIF GPS data (longitude and latitude), and then writes the name of that image and any GPS co-ordinates it finds to a CSV file. Results are written to a file in the pwd as the scan runs. CSV files will be produced by default, use -html for HTML files instead. If the app is not installed as a gem, HTML output requires configuration.
