Is downgrade to version 2 possible?

Q & A
#1

I’m using Aeontimeline v3.1.9.
I still have a v2.3.16 installation on my Windows computer.
Is it possible to migrate/convert/export my .aeon file to use in Aeontimeline v2.3.16?

You can run both version 2 and 3 on the same computer, you just need to be sure that you install to different folders.

I think it should be possible to export events, characters, locations, and arcs as csv with Aeon 3 and import them into a new project with Aeon 2. But I don’t know what relationships can be transferred in the process.

If you are a programmer, you can read the .aeon file with a script and create an .aeonzip file from the data. I have created Python program libraries that can read both file formats, and write the .aeonzip format. But because those were intended for a different purpose (data exchange with yWriter), you would first need to understand and adapt them to combine them appropriately.
See the extract_json.py script and the aeon3yw and aeon2yw projects on GitHub.

Thank you.
Aeon v2 had a webexport function, since v3 it is promised, I becomes urgent to have that webexport funtion again. I try to find a way to use the webexport function in Aeon v2.
I am not a professional programmer, just an amateur so I can try it. Where can I find documentation about both fileformats?

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

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?

Thanks.
I tried csv transfer but this gave no good results.

If your Aeon 3 project is not excessively complex, but has just too many events on the timeline to rebuild with Aeon 2, you could also try to create a yWriter project with aeon3yw and then convert it to an Aeon2 project with aeon2yw . That is, synchronize with an empty Aeon 2 project. The yWriter project file (.yw7) serves only as an intermediate format, so you don’t need a yWriter installation. With the help of configuration files you can control this process to some extent, but you have to deal with the instructions for use in any case.

EDIT:
Be aware, however, that such an approach is not what these file converters are intended for. It is quite possible that the results obtained with them do not surpass the CSV transfer.

Hello, would it be possible to copy the link for aeontime line 2 from the purchased tap in AppStore?

Getting the link from the purchased tab could be done by holding the app then share via email

It’s really required and I’m looking for users that had it previously since it was removed from the AppStore

Being a Windows user, I’m afraid I can’t help you with App Store issues.

Anyway, I notice that you have posted your question in multiple threads, which is bad because the answers can be spread out and there is no coherent discussion with a benefit for the community.
You better limit yourself to the one thread you started and delete the multiple posts.

Many appreciations for the reply, the support team are being nonsense with refusing to provide the link and even inform that they wont reply to my emails, they said there’s no link and when provided the way to get the link they started ignoring, I’m trying to contact users that had it earlier.

We have politely replied and explained this to you in 4 separate emails on this matter:

  1. Since Aeon Timeline 2 is no longer available for sale on the App Store, the only people who can download the app are those who purchased it when it was listed in the App Store.

  2. If you have previously purchased the app, you need to login to the App Store using the Apple ID that was used for the purchase, and then you can download the app via the list of previous purchases in the App Store.

  3. We are unable to provide assistance with your Apple ID, so if you are unable to login to the account that made the purchase, that is something you will need to follow up with Apple directly to recover access to the Apple ID that made the purchase.

  4. If you have not previously purchased version 2 on iOS, there is no means by which you can download, purchase or run the app now.

  5. Aside from the steps listed above, there is literally no other way to access Aeon Timeline 2 for iOS, and there is no other link that we can provide to you that will work around this if you do not have access to an Apple ID that purchased it.

  6. All links to the App Store, including one obtained using the steps requested above, will simply show you a message saying “the app is not for sale in your region”, unless you are logged in with an account that has previously purchased the app.

As I said in several prior emails, there is no more assistance we can provide to you on this matter. You will need to follow up with Apple to recover a previous purchase (if one was ever made).

Note that files created in version 2 can be opened in version 3, which can be downloaded and used in a free reader mode.

As mentioned in a previous email, we can also offer an upgrade discount if you are able to provide evidence of a version 2 purchase.

Regards,
Matt
