Exposing Metadata: Use Cases

Use Case: Exposing Image Descriptions

Exposing metadata image descriptions like Exchangeable Image File (EXIF), International Press Telecommunications Council (IPTC), and Extensible Metadata Platform (XMP), so that users can access them.


  • A photographer takes a photo with his SLR digital camera. He describes the image in camera via text input (LCD monitor and multi-selector). It is stored in EXIF. He uploads that image to a photo image gallery application that does not offer a means to enter a text alternative. He would like to have that text description available for his visually impaired friends to access directly.
  • A graphic designer creates an image in Photoshop. From the file menu, he chooses "File Info" then enters a IPTC headline and description. He uploads that image to a web page. A visually impaired person wants to directly access that headline and description.


  • A way to directly access EXIF, IPTC, XMP data
