Dear Emil and Agneta,
A warm velcome to Emil.
Re. provenance of the individual numbers and calculations, there
is a good description in the section "Versioning and citation" in
relating to the recommedations from RDA. This is an elegant and
efficient way of handling this issue, I think. I thought I had
added that to the wiki, but right now I cannot find it (?).

I would like to introduce Emil Riis Hansen to the Bonsai
community. He has been recently employed as a research assistant
with the computer science department at Aalborg University.
Emil is interested in working with adding provenance to our
current BONSAI ontology.
Provenance helps us add information on the origin of data.i.e
where does the data come from/ who generated the data/ licence
of the data etc. We had discussed this issue
during the hackathon but hadn't developed it since.
Currently Emil has proposed a high level provenance which is
limited to determining the origin of the dataset and not
individual values in it. For example, if anyone queries data
from BONSAI, they will get the info that the data is sourced
from Exiobase, but if other datasets are integrated to semantic
web using Bonsai ontology, they will find information on the
origin of that dataset. Provenance of individual values in a
dataset is harder to determine as they may be calculated,
estimated, or raw data from the data provider.
Emil is currently also preparing a conference paper with respect
to how he plans to add provenance to the current ontology. For
the purpose of this paper, it would be useful to upload the
provenance information to the current rdf data we have on the
Jena database. This will help the reviewers query the
information as presented in the paper.
If anyone here has been working with provenance or are
interested, please feel free to write to me.
