You confirmed in another question that the software no longer offers EcoSpold 2 export. I have two questions :

  • it seems that you no longer support EcoSpold 2 import either, am I right?
  • if we want to use your import/export maven module instead (olca-io), can we rely on it for EcoSpold 2 ?

Thank you in advance,

Hi Clement,

I am not fully sure I get your point, we do not support ES2 import and export any more because for us the format does not appear to be reliable, no official documentation of the recent version used by the only main user, ecoinvent, and the released ES2 files are not fit for an LCA calculation directly in openLCA. Please therefore rely on the files we release, thank you. And I'd be interested to ask, why do you want to use ES2?

Best wishes,

Well, as said, the JSON-LD format can be used for "accurate life cycle assesments"; we implemented  the initial final version of ES2 and I think were able to understand it, the revisions are not documented as far as I know.
