Summary

Flexible Java library for reading of the EXIF metadata, CRW (Canon raw) metadata and CRW images.

Motivation

History

Early 2002: development starts; some CRW information contributed to David Burren.

Middle of 2002: metadata description in XML introduced.

Early 2003: (pre-release) JAXB 1.0 used to generate classes for the reading of the metadata description from the W3C XML Schema

2005: reading of the metadata description redone using SAX

Early 2006: reader-to-application interface simplified
