I have OmniGraffle 6.6.1 Pro.
There are various pieces of metadata (“Document Data” in omnigraffle) that can be entered into a Omnigraffle document:
However, it seems none of this metadata is kept when Omnigraffle exports a document into PDF. The OSX inspector shows none of the data entered into Omnigraffle, neither can and find any programmatically.
This is a big problem for professional users with lots of documents that are exported to PDF. And here did I think Omnigraffle was a professional tool… :(
Without metadata it is impossible to maintain large numbers of documents in any sensible manner, be it in the file system or, say, a Web CMS, Intranet or Extranet.
What metadata DOES Omnigraffle export with PDF, and how is it stored?
