Hi all, after the call and the discussion I've drafted a possible schema with an example (please see [1]). It is based on the works of : A) A minimal ontology pattern for life cycle assessment data, b

Dear Matteo and all Looks good to me but I am a bit puzzled about two things: Why do we separate between two subclass “input” and “output” when we have already the two relations: “b:isInputOf” and “b:

I think it would be a mistake to bake too many restrictions into the general framework. There is a certain mental model that prevails in LCA, but we don't want BONSAI to accept these restrictions at t

Chris is right that one can use a negative (= input) reference flow. I just never use this approach and I forgot, my mistake. I don’t see how we can skip the reference flow concept though if we are go

(Disclaimer: I am simplifying things a bit here I hope the LCA people will forgive me) Dear Matteo I believe you have understood how it works, but there are some other details that perhaps you should

Good point Massimo. In Fact, the output flow of the activity "Waste Incineration" should be "TREATED municipal solid waste" and not "Treatment of municipal solid waste" Michele

Dear all- I very much appreciate the work and active participation of people in this working group! Unfortunately, I must make your lives a little bit harder :) 1. The final proposal should include no

Hi, I think that using negative inputs to indicate an outputs is already a complication that may be not clear for many people. I think that Bonsai can be also used by the IO community, not just by LCA

Just to chip in on the discussion on waste and waste treatment activities: - The problem that a service activity often has the same name as the service that it provides is a well-known problem. It is

I guess I am missing something here - I was imagining a system where GDP, etc. would exactly be raw data inputs, and used to validate/estimate error on how much of the economy/whatever our system is a

I definetely agree on this. We should probably have a shared notebook for this, I think we will lose track of emails. A document on github and using issues? Some other form of collaborative writing? T

Sorry if sounded smart or know-all I just wanted to explain to Matteo some of the issues in layman terms. I apologized for my mistake on the negative input straight away so I assume we can make peace

Thanks Bo, this was really helpful for me (and hopefully for others) - it shows the power of what you have developed over the last years, and really helps me understand it on a more fundamental level.

Hi all, an important initial step to align our intentions and clarify the scope of the ontology and the goals of the database is to identify a set of "Competency Questions". Those are questions that s

I would like to attack this a bit more systematically: Querying the core database alone (noting that the core observations/datapoints are “flows”): (BW_Q1) What is the direct input flow of flow-object
