Are there any Java based Api's for Omniplan
 

Hi,

Does Omniplan provide any Java based api's that can parse an Omniplan document , like how Apache Tika can parse iWork docs (Numbers, Keynote etc)?

What are you trying to accomplish? Instead of trying to parse an OmniPlan file, it might be easier to write an Applescript that runs in OmniPlan (which already knows how to parse OmniPlan files, of course) and generates whatever you are trying to create, especially if the destination is also Applescriptable...
