This might be a vague question, but I failed to rephrase it properly. So here\'s an explanation.
I developed an app that was originally developed as a Mac applicatio
There are many ways to synchronize/communicate the data between two applications, but let me explain the simplest :
RESTful Serialization:
Serialize the objects into XML/JSON or any other custom format both app frameworks can parse. eg. http://docs.python.org/library/json.html
If both apps are on the same server/machine I'm expecting all you have to do is to encode/store the data into the same file(s) and read/parse the data from respective file(s) in other application.
Otherwise you may need to create a web service for accessing the data file.
Let me know in comments if you have further queries.
