I have tried downloading databases from NREL US LCI, this one specifically (https://www.lcacommons.gov/lca-collaboration/National_Renewable_Energy_Laboratory/USLCI/dataset/PROCESS/89a2b59a-1ca2-34f5-acc8-a8eaaa6fa870) and importing them into openLCA 1.8 with no luck. I'm using a Mac with Mojave version 10.14.4. Here's the steps:
download database as JSON-LD --> unzip (open with archive utility)
in openLCA, right click--> new database--> local and complete reference data
double click said database to activate--> right click--> import--> other--> linked data (JSON-LD) --> next
choose directory --> select unzipped file--> okay
I see the folder names "parameters", "flow properties", "unit_groups", "categories", "flows" on the lefthand side box, but nothing shows up in the righthand box when i click or double click them, and I'm not able to select one and hit next.
I also tried selecting just my "Downloads" folder when choosing the directory, then the unzipped database file folder shows up on the lefthand side box of the import window, but again, not able to select anything or get anything to show up in the righthand side box.
I've waded through the other questions on here with related issues with no luck. Any suggestions? Thanks!
