# Minutes ShExCG 2022-12-07
Participants: Andra, Kat, Tom, Eric, Labra



* Tom: my COVID project is to get back to work on DCTap.
 ... DCTapPython does consistency checks
... a 2nd project, TapShEx, imports DCTapPython and generates ShEx
... playing with intersphynx to make TapShex docs import DCTap docs.
... I took ShEx Primer examples into the TapShEx test directory so there are DCTap CSVs which emit the ShEx Primer examples.

* [Intersphinx](https://docs.readthedocs.io/en/stable/guides/intersphinx.html)

* Andra: Josh Moore is working on LinkML. He wrote convertor from DCTap to LinkML.

* Eric: Working on ShExmap extension in Jena, have to a pull request. 
* Eric: Jena released with Semantic Actions


* Kat: Andra and I attended Wikidata Entity Schema Bug Triage Hour.
... On Dec 2, IEEE approved the PAR (Project Authorization Request) for a ShEx WG.
... .. feedback was all editorial, e.g. write out Shape Expressions after first reference to "ShEx"

* Tom: any changes to the CG?
* ericP: I don't think so, apart from a bit more ceremony around decisions.
* Andra: will allow us to say "ShEx is a standard"

* Andra: at Wikidata Entity Schema bug triage hour, folks asked for a YouTube tutorial on YASHE.
... ericP and I are going working with a Rare Diseases project and need a tool to convert from ShEx to SHACL.
* Jose: There are semantic differences, but if you steer away from them, I have a tool that converts.
... you can also author flat shapes in DCTap.uld lose some expressivity but it should meet the 80/20 rule.

* Jose: I'll be teaching an intro do databses to business folks. Will be teaching ShEx and SPARQL.



# Minutes ShExCG 2022-11-23
Participants: Andra, Jose, Kat, Tom, Seyed

## Updates
* Jose: Participated in the biohackathon two weeks ago, where he used ShEx. Jose has [the wdsub tool](https://github.com/weso/wdsub) that create subsets. We used [thes schemas](https://github.com/kg-subsetting/biohackathon2022/tree/main/examples/ShEx)
* Jose: Also met f2f with Eric. Where they discussed templates and ShexMap. On interesting issues is that that the semantics of ShExMaps are a challenge. He will work on those challenges. 
* Job offer: https://www.weso.es/vacancies/2022_11_JobOffer.pdf
* Eric: Eric met with Jose and also worked with claude in Paris where they worked Claude Nanjo who is clinical informatic. Where they worked on the jena implementation of shexmaps. Andy Sheaborne is pestering Eric for moving this forward to have it included in the next release
* Eric: Working on error reporting in ShExJS. 
* Kat: IEEE standards meeting is meeting on Dec 2th. Where the proposal to accept for the ShEx workshop as part of their set of standards. Within IEEE framework provides insight. Currently, 3 yes, and one conditional. 
   * Tom Does that mean we get the infrastructure to work as a group. Kat: don't know
   * 
* Tom: looking forward to have some public face on a project related with shEx
* Seyed: Has also participated in the biohackathon...and managed to solve a problem of counting wikdata items on the subsets.
* Andra: Also worked at the biohackaton with the wdsub tool. Running the tool to create a subset of taxon...Need to traverse the graph to have all related items. Wrote the ShEx that includes all instances or identifiers related with
    * Job offer or internship related with ShEx and maybe ShExML
    * Discussion about project related with creating shapes
        * ShEx foundation
            * Belgium or french foundation
            * Spain?...FUO (Foundation University of Oviedo) possibility to do something like that?
                * Jose: Will ask about possibilities
        * Approaches to create shapes
            * DC-TAP
            * ShEx and converter


# Minutes ShExCG 2022-11-09

Participants:
- Andra, Kat, Jose, Tom


## Updates
* Jose: Jose is at the biohackathon and is making progress on extracting subsets from wikidata using shape expressions. 
* Kat: no updates
* Tom: Some members of this group are part of a new project using shape expressions
* Andra: Virtually participating in biohackathon. Writing a crude shape expression that gets things like look like genes - where much curation needs to happen. Inclined to pull out of Wikidata and process there. Load into GraphDB with OntoText. Gene example is too big to handle in XXX or in Jena. GraphDB uses file system loading, while the others use the Web browser. GraphDB is for running complex SPARQL queries that would time out on Wikidata.

## Minutes

* Jose suggests to take inspiration by the [PDF association](https://www.pdfa.org/) and [this podcast](https://www.se-radio.net/2022/10/episode-532-peter-wyatt-and-duff-johnson-on-30-years-of-pdf/). They became a standard 3 decades ago, but the interesting part is that they also created an international association. 
* Jose reports from the BioHackathon, where they are using ShEx for subsetting Wikidata.
* Jose was working on the extends...it is almost ready, only 3 remaining examples fail... Important for ShEx to keep evolving.
