Hi Carl... Priscilla Caplan asked me a question that I couldn't answer last Friday. "What is the relationship between NISO's work on Technical Metadata for Digital Still Images and METS?" Are your combined allfilesMD and imageMD extension schemas "compliant" with the data dictionary for technical metadata for still images created by NISO? It seems there may be an opportunity here to work together, as NISO does not yet have an encoding scheme proposed for image technical metadata.
