Well the EF3.1 is not available yet from us in Nexus; the use of locations in exchanges in the ILCD format, as is used in these EF3.1 datasets, works only with openLCA 2. In openLCA 1.x, you get the same flow repeated, and you will need to use the "PEFlocus" tool from us to fix that, basically to create one new flow with a location, for each occurance of an exchange with a location, which is not very elegant but works (check
https://github.com/msrocka/peflocus). We will release these datasets soon though (but, because of the way this is organised by the commission, this is basically unpaid work for us since we cannot charge for it due to the license conditions, and the commission does not support us either, and thus we need to find the time for this. And we need to visit all the different nodes to collect the datasets, where every node operator can just update or remove the datasets. In earlier versions, datasets were quite inconsistent, which required some cleaning and curation steps from us, but I hope this is now better).
