@gesinn-it-gea or @JeroenDeDauw is this ready for being accepted?

[krabina]

Can we accept this? @JeroenDeDauw @gesinn-it-gea It is a great idea to have an R result format!

[JeroenDeDauw]

This PR was marked as draft by OP, so IDK if it is even finished

[krabina]

Ah I see. @mfalda is this working well for you?

[mfalda]

I developed these SRFs for a scientific paper just submitted for review. At the end I used only the Prolog predicates idea for the repository smw SWI- Prolog pack, since a colleague told me that data scientists usually create dataframes form plain data formats (that is CSV files). In fact, also Prolog predicates could be created from CSV in Prolog, but I like them more as predicates to be asserte directly. Hopefully, it will be all clearer if the paper will be published ...

I left the pull request in draft since tests are still missing. I do not think that I will develop further the R dataframe format, but in my opinion the possibility to connect from Prolog would be nice.

[mfalda]

In any case, I can remove the "draft" status in the case someone wants to integrate the code.

Great, thank you for the info, good luck for your paper and we hope you stay on board. Please submit a short presentation at SMWCon: https://www.semantic-mediawiki.org/wiki/SMWCon_Fall_2022 As it is not an academic conference, you cannot talk about your paper before it is published, but you could certainly give a short talk about the two new formats in your PR.

[mfalda]

Thank you. I will try to work on a simple example in Prolog and/or R and, if worth, I will propose a brief talk.

@mfalda sorry your brief talk did not happen. Anyway, can you provide us with a simple example so we can test this. I would like to see this integrated.

Hello, it is just an export format, but you can try the Export data page at my demo site: https://dbnsdemo.neuroscienze.unipd.it/wiki/index.php?title=Export_data. I developed the R format for using it in Shiny even if then I found that the CSV format could be simpler. The Prolog format however seems to me more useful and I also have developed a pack for SWI Prolog: https://github.com/mfalda/smw/.

By the way, do you know other semantics-capable systems, apart from MediaWIki, that use Shiny for presenting the data? Thank you very much.

I am sorry, I forgot to specify the credentials! You can login with Username = Test and password = eest .

Can you update your branch? Then I guess there are no conflicts anymore.

[krabina]

@oetterer can you maybe look into this? I'd like to see this merged. Maybe you have a usecase for R or dataframe format?
