I know there is probably no "official" spec for the way annotations are stored in Tiff files. However there appears to be a common method. By this I mean that I am able to create Tag based annotations on tiff image files with several toolkits and successfully read them back with other toolkits.

Does anybody know where I might find a document (official or otherwise) that documents the "Wang Annotation" standard.

Try the IPTC and XMP specs for more recognized standards.
