Series of wrong matches across different graphs

[fjjulien]

Main issue

Gary and detected unexpected events in the upcoming events organized by indigenous agents graph JSON-LD.

The source includes several events from the P'tit bonheur dataset (kg.artsdata.ca/culture-creates/footlight/ptitbonheur-org). The reason these events are selected in the dataset is an inaccurate sameAs. Events in this dataset have two organizer value:

• P'tit bonheur de Sainte-Camille (http://kg.artsdata.ca/resource/K16-62) - the correct value
• Indigenous Curatorial Collective (http://kg.artsdata.ca/resource/K3-181) - an incorrect value

Solution

• All organizer triples in kg.artsdata.ca/culture-creates/footlight/ptitbonheur-org with the value "Indigenous Curatorial Collective" (http://kg.artsdata.ca/resource/K3-181) should be deleted.

Secondary issue

The incorrect organizer value was likely entered as a result of a bad string reconciliation in Footlight console. This bad reconciliation string was itself probably the outcome of an ambiguous data record.

There is a resource named "Camille" (http://lod.footlight.io/resource/665825428c76ef006456521d) that has a few questionable sameAs triples:

Among other things, one of the values is http://kg.artsdata.ca/resource/K2-279, a URI that is no longer accessible in the Artsdata database.

Another value is an IPAA member record (https://ipaa.ca/resource/e0f6c625-9149-468c-b1b5-f0c866f2f767) that also appears to be a broken link.

Solutions

• This entire resource - http://lod.footlight.io/resource/665825428c76ef006456521d - should be deleted.
• Triples pointing to the broken Artsdata URI - http://kg.artsdata.ca/resource/K2-279 - should be deleted.
• Triples pointing to the broken IPAA URI - https://ipaa.ca/resource/e0f6c625-9149-468c-b1b5-f0c866f2f767 - should be deleted.

###Tertiary issue

The data record that appears to be the source of this confusion is https://ipaa.ca/profile/indigenous-organization/Camille_Usher#Organization. This member profile is clearly describing the Indigenous Curatorial Collective, but it is named "Camille Usher" (after the name of the person who filled in the form). I suspect this new name might have been attributed after the organization changed its name from "Aboriginal Curatorial Collective" to "Indigenous Curatorial Collective".

Solutions

I'm not sure...

• At a minimum, the name value in the IPAA database should be changed for that of the organization, rather than Camille.

Changing the IPAA record URL slug is also an option. This would create a new entity URI in Artsdata, which @GaryMan1968 could then manually mint/link to its Artsdata ID.

Or else, we could leave the URL as is and accept the ambiguity of the URI name.

@saumier Any thoughts?

@fjjulien @GaryMan1968 The main data quality issue is fixed.

@fjjulien I deleted this triple: http://kg.artsdata.ca/resource/K3-181 schema:sameAs
https://ipaa.ca/resource/e0f6c625-9149-468c-b1b5-f0c866f2f767

@fjjulien @tammy-culture To fix the Footlights Console for future events that get loaded sometime in the future, I created the organization "P'tit bonheur de Sainte-Camille" in Footlight Console and linked it to K16-62. I did this so new event will have their organizer link to this correct one when there is an exact match.

[fjjulien]

@saumier Thank you for these fixes.

http://lod.footlight.io/resource/665825428c76ef006456521d appears not to be the subject of any triple, and none of its own triples are accurate. Can you please delete it.

[fjjulien]

@saumier This event - http://kg.footlight.io/resource/placedesarts-com_discussion-camille-thurman - has inaccurate performer values pointing to both adr:K2-279 and adr:K3-181. Can you please delete these two triples?

[fjjulien]

@GaryMan1968 Please report on your data cleaning activities in IPAA's database. When you are through and Gregory has performed the two tasks in the above comments, you may close this issue.

[GaryMan1968]

I have sent Dmitri an e-mail about cleaning this record. I have asked him to change both the name and the URL slug. I will update again once he responds.

[GaryMan1968]

Dmitri has updated the member record for ICCA.

[fjjulien]

I refreshed the IPAA dataset. The old "camille" record is no longer there and the new "icca" record was properly loaded: https://ipaa.ca/profile/indigenous-organization/icca#Organization

I was able to manually link this record to the Artsdata ID http://kg.artsdata.ca/resource/K3-181.

@saumier When you've deleted the two triples with the object http://kg.artsdata.ca/resource/K2-279, you may close this issue.

[saumier]

@fjjulien Those 2 triples are not in the Artsdata core. So there is not point in deleting them and there is no need. The 2 "non-authoritative" triples will eventually disappear as their graphs are reloaded and replaced with each refresh. Artsdata is designed to handle mistakes in linking sameAs from external sources. The core is the authoritative reference for all sameAs.
