Is there any documentation on file format?

[Tyson of the Northwest]

Since Publisher currently does not support merging I was wondering what sort of options we would have for a workaround? Is there any documentation of the format of afpub? I was thinking I could potentially write a tool to generate a file that would walk a data source, create elements, size them and place them on pages, then apply the appropriate master page to the page.  From there I could open it in Publisher and modify it appropriately.

Alternatively is there (or will there be) api or plugin support where we could develop such a plugin independently? 

I am developing a Card game and being able to merge from my content source database (or csv export) would make this a perfect product.

There have been indications that the file format may not be 100% stable between now and the release so I don't think they would be too interested in spending time on publishing it at this point.

It is very unlikely that the file format(s) of the Affinity Suite will ever be made public:

One of the key developers also provided technical reasons for this:

Hope that helps …
