[JBoss JIRA] Commented: (DNA-26) Extract EXIF metadata from JPEG files
by Johnny Verhaeg (JIRA)
[ http://jira.jboss.com/jira/browse/DNA-26?page=comments#action_12420178 ]
Johnny Verhaeg commented on DNA-26:
-----------------------------------
I will be adding the 2.4.0 beta1 version of the metadata-extractor library to the JBoss repository since it's a dependency of Aperture, which I need to add to the repository as part DNA-126.

> The image sequencer extracts basic metadata from PNG, BMP, JPEG, GIF and other image files. Enhance this sequencer to extract EXIF metadata for JPEG files.
> Drew Noake's metadata extractor (http://www.drewnoakes.com/code/exif/index.html) seems to be a widely used library for extracting EXIF metadata, and has support for a number of cameras. This library does not appear to be in a any of the Maven 2 repositories, and Drew does not specify the Maven coordinates. The package structure is "com.drew.*", but Aduna has it in its Maven 2 repository (http://repository.aduna-software.org/maven2/com/drewnoakes/metadata-extra...) under "com.drewnoakes" (which is Drew's domain).
> The EXIF metadata is organized as tags under directories. See a sample output of EXIF metadata at http://www.drewnoakes.com/code/exif/sampleOutput.html. This could be mapped to JCR by having a child node (of type "exif:directory") named for each directory (e.g., "EXIF"). Should the tags be stored as properties on each directory node (not a great mapping from the tag names to property names, and not really very extensible but probably easier to use), or as child nodes (of type "exit:tag" ?) with properties for the tag name, hex value, and description (value)?
