I'm replying to my own post here. Thanks to a couple of replies on the recorder forum (Thanks Charles & David) it seems that exporting in NBN zipped format breaks imports to Recorder 2002!
There is the fall back to the XML NBN format, but one of the reasons the zipped came about (AFAIK) was XML in Recorder 2002 was poor!
At BIS, failure rate with XML nearly 90%, failure rate with zipped format 0%.
We have a workflow based on the exchange of NBN Zipped files with our recorders who use Recorder 2000, now I'm *forced* to make changes, test and support this workflow. Not good.
I hope this time the parser in Recorder 6 is more robust. I have just had a quick look at an XML export from Recorder 6 and (as in Recorder 2000) the use of RFT in comments or geographic location fields leaves a malformed XML tag in the resultant file.
I will test this out a bit more. XML has to work 100% in both directions if this is all we have to work with between versions.
