Is downgrade to version 2 possible?

Where can I find documentation about both fileformats?

There is an extensive discussion about the Aeon file formats in another thread:

What is the data format of an *.aeon file?

I would like to try and link/sync an Aeon timeline directly with an external data source (a bit like the Scrivener sync feature). I noticed that the timeline data is stored in a binary file in what looks like JSON format. I would like to create timelines directly from DB data and have changes made in the timeline written back to the DB, without going through an Import/Export procedure. Is this possible, and what would be the right format to read open/read/write the binary *.aeon file?

In short: Both Aeon 2 and Aeon 3 organize the data as JSON data structure, so you can use any programming language with JSON support.

• Aeon 2 compresses the JSON file to a ZIP container.
• Aeon 3 merges the JSON data with other binary data.

The extract_json.py script linked above can read both formats and create a JSON file that you can inspect with any text editor, preferably one with JSON syntax highlighting.

The internal structure of the JSON files from Aeon 2 and Aeon 3 are somewhat different. I don’t know whether there is an official specification; I just analyzed the data structures with a small project. The data structures are not exactly straightforward; there is a lot of need to look up UIDs and to track references across the whole file. So if you are a beginner in programming, this could be quite a challenge.

Have you already tried the csv transfer?
