Importing items from Yojimbo

Due to changes to Yojimbo, I have decided to switch to DEVONthink PRO. How could I import the items I have In Yojimbo to DT? I believe Yojimbo uses a Openbase engine.

Any suggestions are greatly appreciated.

Yojimbo’s website states: “You can get anything out of Yojimbo you put into it, too, in its original form. There’s no lock-in, export any time.”

So why not simply first export, then import into DEVONthink Pro (Office)? DEVONthink Pro (Office) will retain the Finder’s folder structure of the exported items on import.
