File Metadata

Im currently midways through a couple of little scripts… Im going to be adding additional metadata to my artwork files…

Bear in mind… once I have done this they are probably/likely going to be put in to some asset management system…

I just don't know which one just yet… ( something like Portfolio Server 11 )

The getting of the extra info that I want is almost done…

What I wondering as a relative noob to XMP schema and such is… Where in the XMP is best to store this…?

Currently in my tests Im putting it in the 'http://purl.org/dc/elements/1.1/', subject bag…

What I don't know is how much info I can put in here… does it have any limitations…?

Another possible option is I could just create a custom namespace and put a couple of bags in that…?

… but is some other sofware going to see this data…

My other thoughts were can I stick some bags in the PS, AI & ID namespaces…

… don't yet know if Im allowed access to do that? or if for some reasons unknown to me this is not advisable…

The do's and dont's of XMP schema are new to me as Asset Management is about to be… eeeek

If there are any pros n cons on the above… or Asset Management recommendations I would like to hear…
