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) Improve 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.

Regards

Hi,

I am partially available on Friday October 2th morning.
If you can setup a zoom meeting so that we can participate that would be great guys.

cheers,
Michele De Rosa
 

Hi Tomas,

that sounds great.

Here is the link to the zoom meeting:

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
