[Metadatalibrarians] IPTC metadata

[Kristin E. Martin]

Kris,

I appreciate your willingness to share information. For clarification, 
with your in-house standard, are you embedding all of the metadata into 
the image?  Or is your descriptive information existing outside of the 
image?

As I investigate this further, I may have more questions!
