Abstract
EXIF is a common standard of basic image metadata used in digital cameras and in image management software. Masahide Kanzaki created an ontology that allows the EXIF metadata to be expressed in RDF. NEXIF is a simple adaptation of the Kanzaki's ontology to fit it into the Nepomuk Information Element Framework.Table of Contents

Exchangeable Image Format (EXIF) is a specification of image metadata vocabulary published by the Japan Electronics and Information Technology Industries Association [EXIFSPEC]. It has gained wide acceptance within the digital photography community. Most of today's digital cameras annotate the pictures with EXIF annotations.
An Exif description is to a large extent a set of name/value pairs. Exif descriptions have little structural information, apart from simple part-of relationships. Therefore adapting it to RDF is quite straightforward. This has been expertly done by Masahide Kanzaki [EXIFRDF]. His ontology meticulously recreates all properties defined in the specification document as rdf properties. They don't have their domains and ranges specified though. Therefore, during the adaptation of Kanzaki ontology to the Nepomuk Representational Language the domains and ranges have been added.
The Nepomuk Exif Ontology (NEXIF) has been linked with two other ontologies. The first link allows for easy annotation of image files with exif properties. It has been realized with the nexif:Photo class, which is a subclass of nfo:Image.
