The Metadata Working Group, which is an alliance between Adobe, Apple, Canon, Microsoft, Nokia and Sony published its first guidelines on the use of image metadata this week. The guidelines suggest methods to increase interoperability and storage of shooting settings and other associated data in digital images. It aims at standardizing the availability of metadata across all applications and devices, making it easier for users to create, organize and share their pictures.

Image MetadataLack of metadata interoperability has led to significant frustration for both consumer and pro photographers. Metadata, sometimes referred to as “data about data,” is important to digital photography because it allows photographers to tag their digital photos with information such as where and when they were taken.

For both professional photographers and consumers, this enables basic activities such as being able to find and share photos. Although the digital photography industry has several metadata standards, these existing standards often overlap in purpose and lack interoperability guidance.

The result is that many interoperability scenarios between devices, applications and services are not possible because no clearly defined rules and standards exist to ensure consistent use. The Metadata Working Group’s initial guidelines target still photo metadata, with a focus on common consumer uses.
