Unfortunately a lot of things changed in the import/export toolkit between OJS 2.x and 3.x, so it’s hard to come up with an apples-to-apples comparison or convert XML between the two formats.
The only way to “automatically” adapt content from OJS 2.x XML to OJS 3.x XML is to…
- Import the content into an OJS 2.x install
- Run the upgrade script to upgrade the installation to OJS 3.x
- Export the content again from the upgraded OJS 3.x install
In the future we may write an XSL to convert between the formats, but it would take considerable effort.
I would suggest looking at sample content for both versions. You can find sample for each at…
Note that the content in the two samples is different – and one is validated by DTD, and the other by XML schema.
