ESWC 2019 Trip Report

Matteo Lissandrini (AAU)
 

Hi all,

I'm back from ESWC'19 in Portorož, Slovenia.
The conference is a well known venue for Semantic Web researchers and practitioners.

I've presented our work with the poster and we were lucky enough to win the best poster award:
https://2019.eswc-conferences.org/awards/

In general I've talked to other people that worked in building ontologies and we all shared the struggle in finding the right vocabulary, and how to better reuse the existing ones and the standards.
I've added a couple of interesting pointers as issues on github.

For validation of user-submitted data, WikiData recently  started adopting Shape Expressions
http://shex.io/

For statistical data other groups suggested looking into the "statistical ontology"
http://stato-ontology.org/
this one probably could represent the data that has uncertainty attached to it.

A tool for visualization and editing of ontologies:
http://owlgred.lumii.lv/

Among the people passing by asking for questions a person from Daimler expressed some interest, while a researcher from the German Aerospace Center was interested in understanding the Bonsai use case in relation to a W3C working group in which they are participating.

We also got general approval from some design choices, among which the Ontology of Unit of measures we picked.

Please let me know if you have any further questions.

Thanks,
Matteo

Collaboration with TRASE project

 

Dear all-

I just had a productive conversation with Javier Godar and Michael
Lathuillière from the TRASE project (https://trase.earth/). They are
doing some really nice work (and already have some nice results!) in
parallel with BONSAI, and have similar perspectives on open data and
the value of open science. For example, they combine tax records,
customs data, real-time ship monitoring (via satellite transponders),
agricultural extension service municipal-level data, and other
non-traditional data sources to get detailed footprints of
agricultural commodity exports from several countries (see
https://scholar.google.com/citations?hl=en&user=TIvEczoAAAAJ&sortby=pubdate).
They also have existing collaborations with partners many of us would
know about. They are also testing a switch from a relational DB to a
graph-based DB.

The next steps would be:

- Invite someone(s) from TRASE to come to the next hackathon
- Include TRASE in future grant proposals
- I will have another call with them in the fall, and will invite
BONSAIers to participate

opemod Aarhus

Miguel Fernández Astudillo
 

Dear all

 

A couple of months ago I went to the openmod workshop in Aarhus. One of the “do-a-thons” was a discussion about the ontology of scenarios. They are trying to find common ways to express scenarios resulting from different models so that they can be reused and compared. We discussed a bit about Bonsai, and they are of course interested. I think they have given a lot of thought to the concept of scenarios and I see them as interesting potential collaborators.

 

The talk was animated by Martin Glauer

Miguel

 


International emissions inventory conference

 

Dear fellow Bonsamurais-

Just a quick note to let you know that I am currently at the International Emissions Inventory conference (agenda here) hosted by the US EPA. I will be presenting BONSAI, and talking about our idea of using independent data to validate and quantify uncertainty for our global and regional emission and production values. This is the real deal, people who know the details about measurements and models (e.g. in 30 minutes I will be at a talk on how to combine models, surrogate data, on-site measurements, and airborne observations to estimate total CH4 emissions for oil and gas production in the US), so let me know if you have any specific talks or questions.

Re: SDG follow upSETAC UNOPS

LCA LCT
 

For the first time, sustainable development, broadly defined and all-encompassing, has been enshrined in international policy discussions and quickly adopted by national governments, NGOs and the global business community. The 17 SDGs are comprehensive and cover energy and climate; water, food and ecosystems; health and poverty; and jobs and innovation. The SDGs represent a major step forward towards linking human activity to economic, social or environmental consequences.

The SDGs introduce the added benefit of encouraging the partnership of governments, private sector, civil society and citizens alike to make sure we leave a better planet for future generations. Governments throughout the world have declared the 17 SDGs and the 169 targets to be integrated and essential for future prosperity. The business community is reflecting on the relationships between the SDGs and sustainable corporate practices. The scientific community plays a critical role through research and experimentation to fill knowledge gaps in critical areas that elucidate the consequences of human activities.

The SDGs are guide-posts for society as it attempts to respond to an array of pressing environmental challenges. Five years into the initiative, the editors felt it was a good time to explore where the research is and what is still needed to support these goals.

During the editorial meeting at the SETAC Europe 29th Annual Meeting in Helsinki, Finland, attendees identified the following goals as most pertinent to IEAM:

  • Goal 2: Promote sustainable agriculture.
  • Goal 6: Ensure availability and sustainable management of water and sanitation for all.
  • Goal 11: Incorporate nature into the human built environment to support urban ecosystem services.
  • Goal 12: Ensure sustainable consumption and production patterns.
  • Goal 13: Implement strategies and actions to respond to climate change and its impacts.
  • Goal 14: Conserve and use the oceans, seas and marine resources for sustainable development.
  • Goal 15: Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, halt or reverse land degradation, and halt biodiversity loss.

We are seeking experts to submit full-length articles or write perspectives on their work pertaining to an SDG goal. Perspectives are short articles, 2–3 pages long, that:

  • Frame SDG goal relevant to the author’s region or research.
  • State the problem that the research is seeking to address and why it is important.
  • Propose a solution or explain the work still needed that will lead towards a solution.
  • Report any findings and the status.
  • Call for next steps or seek collaborations.

We encourage potential authors to read our revised aims and scope, familiarize themselves with the author guidelinescontact us with any questions and submit their work!

Dear all,

the Denmark-based Bonsamurais have thought to arrange a 2 days in-person workshop to follow-up on some of the open issues left after the hackathon.
The idea is to refresh our memories and hopefully to deliver some useful work in preparation for the next hackathon.

We have identified the following two days as a good fit for the 5 of us in Denmark (Agneta, MASsimo, MATteo, MIChele, MIGuel):

Friday 25 October            - 9:30 to 16:00
Saturday 26th October   - 9:00 to 15:30
 
We will be working from Aalborg, probably on some of the open issues of the BONSAI-ontology-RDF-framework or of the Correspondence-tables but we will be happy if anybody wants to join us remotely, even for a few hours. Please get in contact with me privately and we will figure out how to connect you remotely.   

Here are some suggestions on topics we might work on:

1) Conversion of remaining data in Exiobase to RDF. For example, currently only the USE and SUPPLY tables have been converted based on the BONSAI core ontology. We still need to convert the extended tables in exiobase (that contain data on emissions etc) to RDF.
 
For example, discussion are needed to make the conversion in the following cases:
    - Issue 1 The USE table in Exiobase contains info on country of origin of the flow object (only Activity type and agent have location). This has not been incorporated in the core ontology. This needs discussion
    - Issue 2 Certain flow objects and activity type instances present in the extended tables have not been defined. 
 
2)  Establish and document RDF vocabulary for correspondence tables: Currently it is still not clear which correspondence predicates are to be used and why. This is for open discussion on pros and cons of the various predicates available for correspondence from well established ontologies such as OWL and SKOS.
 
3) How to use Exiobase data in RDF format: the mojo repository was developed to convert raw rdf data into a computation structure (A matrix). The beebee repository was created to ensure the use of this data on open software such as brightway. However, the information and code in both repositories are not sufficient yet. This could be worked on.

4) I
mprove documentation which is currently very scattered (already ongoing work)
 
Further suggestions and discussions are welcome.

Thanks for taking the initiative.

I can attend remotely until 12:30 both days.

Re. Issue 1 The USE table in Exiobase contains info on country of origin of the flow object (only Activity type and agent have location). This has not been incorporated in the core ontology" I have added this comment: "The current ontology already allows a flow to be bont:outputOf one activity and bont:inputOf another activity. But for the SUT, the product flow origin is redundant information that should be ignored. In a true SUT, the flows enter and leave an activity but do not yet have information on their origin and destination. This information is added when linking the different activities into a Direct Requirements Matrix. The EXIOBASE SUT is overspecified in this sense that it already has interpreted the information in the trade statistics in a specific (attributional) way. This error should not be imported into the BONSAI implementation, which should leave the user free to link SUT activities with different linking algorithms (including one that we may decide on being the preferred consensus one for "official" BONSAI footprints)."

Hi everyone

I have uploaded a .md document with a short summary of the  BONSAMURAIS repositories here . This document can be found in the repository named bonsai (which is pinned as the main repository under BONSAMURAIS).
I hope this is useful as a starting point to navigate through the different repositories and the work of different groups. Please feel free to write to me if you think additional information should be added.

Thanks everyone for coming on board with the mini hackathon this weekend. Here are the minutes on what what we have been working with:

1- Clarified how different repositories are linked together. This information is updated in the bonsai main repository. The link to this repository is on the BONSAI web page. (Michele, Agneta, Massimo, Miguel) 
2- Documentation of individual repositories is currently being reviewed. (Michele, Agneta, Carlos, Miguel)

3- .ttl files can now be accessed from rdf.bonsai.uno (Tomas)
4- Correspondence tables were developed. Trying to create python skeleton for correspondence table #issue25 on this repo. There is also an update on #issue21 on how rdf of correspondece tables could be structured. (Miguel, Massimo)
5- Arborist inspired functions to create .ttl files from correspondence tables. (Miguel, Massimo)
6- Started creation of metadata for all csv tables. (Miguel, Massimo, Michele)
7- Environmentally extended exiobase tables are being converted to .ttl files (Chris)
8- An issue on addressing the location attached to flowobject has been closed. This issue was due to reconstruction of SUT data with trade data. Details on this is uploaded on mojo repository. (Bo, Michele, Matteo)
9- Due to the above change, the current code to convert exiobase to rdf has to be modified (Matteo)
10- The Jena triplestore is now open to everybody to query (i.e. does not need password). Password is still required to upload data (Matteo)
11- Deprecated repositories are achived (Tomas, Agneta)

Good work everyone !!!

Cheers

Agneta


Collaboration between US EPA and BONSAI

 

Dear all-

Though you might not have heard about it, the US EPA has made a major
commitment towards building an open data and open source toolchain for
LCA, primarily for supporting projects by federal agencies in the US.
This includes:

* Almost 10.000 activities provided as open linked data (in JSON-LD)
format via lcacommons.gov
* Very active Github repos on elementary flows lists
(https://github.com/USEPA/Federal-LCA-Commons-Elementary-Flow-List),
standardizing, processing, and releasing electricity inventories
(https://github.com/USEPA/ElectricityLCI), a detailed EEIO table for
the US (https://github.com/USEPA/USEEIO), and standardizing and
working with LCIA method implementations
(https://github.com/USEPA/LCIAformatter).

I think BONSAI both has a lot to learn from, and a lot to contribute
to, this effort. As such, I think we urgently should get to know each
other a bit. One possibility would be a 1-2 hour teleconference, where
we each present our work, and discuss practical steps towards how we
can help each other. Wes, please let us know if you would be
interested (BONSAI is an open organization, you join by posting to the
mailing list).

To everyone else, please think a bit about a) where people who have to
produce a complete working LCA system are choosing to invest their
time, and whether there are any lessons for BONSAI, and b) why we have
not been invited to be a part of this effort so far (what have been
our weaknesses?). BONSAI is both a concrete set of source code
repositories and a network of experts who are passionate about
changing the status quo, we need to do a better job of helping people
down productive paths and benefiting from our experience (see also a
few more mails coming from me this evening :)

Introducing Thomas Maël

 

Dear all-

I recently had the pleasure of getting to know Thomas Maël, and
exchanging messages on Hacker News
(https://news.ycombinator.com/item?id=21186182). Thomas is the author
of https://futur.eco/, a tool that he put together in his spare time,
and exactly the sort of thing that BONSAI should be the default data
source for (Il n'est disponible qu'en français, mais j'espère que ce
n'est pas un problème pour vous).

Thomas will probably join the hackathon in the spring; Thomas, BONSAI
is an open community, meaning that you join by posting to the mailing
list. So post away :) To those working on the website, this is exactly
where we would like to have a link to a beginner's guide!

Thinking about how best to leverage our work so far

 

Dear all-

Disclaimer: The following could all be incorrect, it's late, I'm
tired, people make mistakes, etc.

As far as I know, there are currently three initiatives started
recently to build large, open LCI databases: The PEF in Europe, the
effort to harmonize LCI data generation in the US (led by the US EPA,
but involving many federal agencies, see previous mailing list post),
and a new database to be created in Canada.

The PEF was led, or at least steered, by people with a lot of
experience in the LCA community, and they followed their habits (and
EU political instructions), by buying data from commercial databases
(I include ecoinvent here), but requiring data delivery in the ILCD
format. The PEF was a bit strange in that each product category went
through a separate bidding process, as so each product category
database lives on its own. Aggregated data is available, but not under
an open license (see examples here: https://ecoinvent.lca-data.com/).

The US EPA has a history of collaboration with Green Delta, built on
their use of the OpenLCA software. OpenLCA is attractive both because
it is open source and free (not the same thing :), but also because it
is easy to deploy to many partners without too much training. As part
of this collaboration, they developed the OpenLCA JSON-LD format
(https://github.com/GreenDelta/olca-schema), which they use
extensively, both in exchanging datasets and databases, but also in
their tooling, elementary flow lists, etc. OLCA schema is different
than our ontology, but it is a semantic web ontology, and it has great
documentation and examples. Development by both US EPA and GreenDelta
take place on GitHub, with a core group of a few people contributing
most of the work.

The Canadian effort is still under development, but is leaning towards
working deeply with ecoinvent, which means not just integrating well
with ecoinvent, but also adopting their toolchain for data input and
validation, system modelling, etc. One person who is part of this
effort told me (and I paraphrase): "I am sympathetic to working more
closely with BONSAI, but I don't have anything hard to bring into
meetings with others who appreciate open data as a practical good
instead of a philosophical one." And they are right! Currently, we
can't really point to a finished tool chain, though we are obviously
trying to change this as fast as possible, thanks again to the Aalborg
crew for the mini-hackathon this weekend.

So BONSAI has effectively zero contribution to any of these three
databases, even though all three are or will be open data.

What I want to say is simple: There are a million problems, including
a lot of fun ones. BONSAI really suffers from the fact that most of us
are volunteers, and as such we want to work on fun problems, and not
necessarily doing the second 90% of the work
(https://en.wikipedia.org/wiki/Ninety-ninety_rule) that is needed to
bring a tool from proof of concept to something that can be used by
many people in actual practice. We have a lot of experience, and have
made a lot of decisions as a group in a systematic and organized
fashion, but we need to do a better job of translating our knowledge
base into material that is easy for other to understand, benefit from,
and use as arguments to build systems compatible with BONSAI.

I contend that, after completing the 2019 hackathon toolchain, the
most effective use of our resources would be to help others make
systems that build on and work with BONSAI. If this supposition was
true, how would this change where you chose to focus the limited free
time you have available?

Re: Thinking about how best to leverage our work so far

Eric Mieras
 

Hi Chris,

Although I have not been involved in the discussions lately, I wanted to respond to these observations as I think they make a lot of sense. As you know, we as PRé also started a Community Driven Initiative (CDLCI) together with some of the major database providers to make it easier to make sector and region specific data available. For that, we also collaborated with BONSAI and because we see a lot of value we also sponsored the hackathon. With CDLCI we want to focus on making the core data and methodological/procedural guidance available that everybody needs to build a database. Next to that, we're currently working on a number of projects to make regional databases available by unlocking data that is now only accessible within research institutes and other organizations. So, we're making progress but from time to time I have the same feeling that you express. There's so much to do and only limited time and resources. In my opinion the key issue is that everybody has the same "dream" and tries to achieve that (too much) on its own. If we can combine all the existing initiatives and identify where everybody's resources would be most effective I believe we can make much more progress. For that, we probably have to think about how to organize this ecosystem and what role everybody wants to play in that. If there's no attention to organizing this, the risk is that BONSAI identifies where it can have the biggest impact but that the direction is not aligned with the other actors in the ecosystem that can benefit from it.

I realize this is not a direct answer to your question, but I believe it's important to consider this when thinking about where you chose to focus the limited free time you have available. Hope this helps the discussion forward.

Best,

Eric Mieras

Subject: [bonsai] Thinking about how best to leverage our work so far

Dear all-

Disclaimer: The following could all be incorrect, it's late, I'm tired, people make mistakes, etc.

As far as I know, there are currently three initiatives started recently to build large, open LCI databases: The PEF in Europe, the effort to harmonize LCI data generation in the US (led by the US EPA, but involving many federal agencies, see previous mailing list post), and a new database to be created in Canada.

The PEF was led, or at least steered, by people with a lot of experience in the LCA community, and they followed their habits (and EU political instructions), by buying data from commercial databases (I include ecoinvent here), but requiring data delivery in the ILCD format. The PEF was a bit strange in that each product category went through a separate bidding process, as so each product category database lives on its own. Aggregated data is available, but not under an open license (see examples here: https://ecoinvent.lca-data.com/).

The US EPA has a history of collaboration with Green Delta, built on their use of the OpenLCA software. OpenLCA is attractive both because it is open source and free (not the same thing :), but also because it is easy to deploy to many partners without too much training. As part of this collaboration, they developed the OpenLCA JSON-LD format (https://github.com/GreenDelta/olca-schema), which they use extensively, both in exchanging datasets and databases, but also in their tooling, elementary flow lists, etc. OLCA schema is different than our ontology, but it is a semantic web ontology, and it has great documentation and examples. Development by both US EPA and GreenDelta take place on GitHub, with a core group of a few people contributing most of the work.

The Canadian effort is still under development, but is leaning towards working deeply with ecoinvent, which means not just integrating well with ecoinvent, but also adopting their toolchain for data input and validation, system modelling, etc. One person who is part of this effort told me (and I paraphrase): "I am sympathetic to working more closely with BONSAI, but I don't have anything hard to bring into meetings with others who appreciate open data as a practical good instead of a philosophical one." And they are right! Currently, we can't really point to a finished tool chain, though we are obviously trying to change this as fast as possible, thanks again to the Aalborg crew for the mini-hackathon this weekend.

So BONSAI has effectively zero contribution to any of these three databases, even though all three are or will be open data.

What I want to say is simple: There are a million problems, including a lot of fun ones. BONSAI really suffers from the fact that most of us are volunteers, and as such we want to work on fun problems, and not necessarily doing the second 90% of the work
(https://en.wikipedia.org/wiki/Ninety-ninety_rule) that is needed to bring a tool from proof of concept to something that can be used by many people in actual practice. We have a lot of experience, and have made a lot of decisions as a group in a systematic and organized fashion, but we need to do a better job of translating our knowledge base into material that is easy for other to understand, benefit from, and use as arguments to build systems compatible with BONSAI.

I contend that, after completing the 2019 hackathon toolchain, the most effective use of our resources would be to help others make systems that build on and work with BONSAI. If this supposition was true, how would this change where you chose to focus the limited free time you have available?
