The Stock Artists Alliance in conjunction with the LOC relays some invaluable information regarding photo metadata on the website PhotoMetadata.org. Embedding metadata on photos is vitally important to aid in identification of the creator, prevent copyright infringement and increase findability.
From informative tutorials, links to resources, explanations of metadata classes, types and structure to glossaries and a reference library, this site backs up the SAA’s Metadata Manifesto with useful and practical information.
The bottom line is that anyone creating photos should understand and employ metadata. In this digital age, content is misappropriated more than ever before. Also, with so much content out there, ensuring that your creations can be easily located is key.
