Exif vocabulary workspace - RDF Schema

Nearby: ESW:ImageDescription Wiki entry

This is a workspace for RDF Interest Group Geo vocabulary work, starting with an emphasis on representing EXIF data in RDF.

This document has been created and maintained initially by Kanzaki (神崎正英).

An Exif Vocabulary

Vocabulary to describe an Exif format picture data. All Exif 2.2 tags are defined as RDF properties, as well as several terms to help this schema. The EXIF RDF Schema is http://www.w3.org/2003/12/exif/ns
