- Separate package for the resources (seems to be a lot)? - Move to metadata package, or implement metadata interface, as this is (similar|equivalent) to TIFF/JPEG APP13 segment tag? - Possibility to read only some resources? readResources(int[] resourceKeys)? - Probably faster when we only need the color space - Support for Photoshop specific TIFF tags (extension for TIFFImageReader)? - PSDImageWriter?
