We would require to fetch the EXIF Information from the Image so we can set as metadata in AEM Dam.
when I upload assets into DAM, I would require color space(Custom Metadata field ) metadata field to be autopopulated from EXIF information. The list includes: CMYK, PMS and RGB. The autopopulation of color space will save designer's time.
Please suggest best way to extract EXIF Information on AEM Custom Workflow process.
Exchangeable image file format (Exif) is the most popular metadata format used in digital photography. It provides a way of embedding a fixed vocabulary of metadata properties in many file formats, such as JPEG, TIFF, RIFF, and WAV. Exif stores metadata as pairs of a metadata name and a metadata value. These metadata name-value-pairs are also called tags, not to be confused with the tagging in Experience Manager. Modern digital cameras create Exif metadata and modern graphics software support it. Exif format is the lowest common denominator for metadata management especially for images.
A major limitation of Exif is that a few popular image file formats such as BMP, GIF, or PNG do not support it.
Metadata fields defined by Exif are typically technical in nature and are of limited use for descriptive metadata management. For this reason, Experience Manager Assets offers mapping of Exif properties intocommon metadata schemataand intoXMP.
