The RISM property reconciliation is incomplete and needs reviewing.

1. Among the keys in the JSON files, why there are "http://www.wikidata.org/prop/direct/P2308"(class) "http://www.wikidata.org/prop/direct/P2888"(exact match) which are from Wikidata's properties?

and how to use P2308? E.g.,

<https://rism.online/institutions/30000440> a ns1:Institution ;
    rdfs:label "Bibliothèque royale de Belgique (KBR) - Koninklijke Bibliotheek van België (KBR), Bruxelles; Brussel (B-Br)"@none ;
    wdt:P2308 wd:Q178706 ; # wd:Q178706 is institution
    wdt:P2888 wd:Q98214461 .

--from merged.ttl

2. How is the URI <https://rism.online/api/v1#> generated?

3. Some reconciled instances may not be accurate:

<https://rism.online/institutions/30000440> wdt:P2888 wd:Q98214461 .

4. Please see the original code snippet before reconciliation:

@prefix dcterms: <http://purl.org/dc/terms/> .
@prefix ns1: <https://rism.online/api/v1#> .
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

<https://rism.online/sources/1000000001> a ns1:Source ;
    rdfs:label "3 Trios; Print"@en ;
    dcterms:creator <https://rism.online/people/94547> ;
    ns1:hasDates [ ns1:dateStatement "[ca. 1800]" ;
            ns1:earliestDate 1800 ;
            ns1:latestDate 1800 ] ;
    ns1:hasHolding <https://rism.online/sources/1000000001/holdings/51006604> ;

• If entering https://rism.online/sources/1000000001/holdings/51006604, I see some json file beginning with "Unexpected response". @ahankinson Hi, Andrew, could you please tell me what the matter is?(See the screenshot:)

5. What does "Source contents" mean? E.g.,

Does it mean that 2 Psalms; Manuscript copy; E-SC 55/4 sources from Memor esto verbi tui; Autograph manuscript; E-SC 55/4?

6. What is the type of the value of property :hasSubject? (what does this mean) E.g., entering https://rism.online/subjects/25250, only to see:

Unexpected response

As of Feb 21, 2025, the properties which cannot be reconciled can be seen as follows:

    "https://rism.online/api/v1#hasIncipit": "P1922", first line
    // Yueqiao: used P286 (head coach). Junjun: in RISM, the values of this property are such as,"F", "9t", "7t", "D", "D, E|b, F, D, G". They are about key or mode in context of music scores. There is not a suitable property in Wikidata for this:
    "https://rism.online/api/v1#hasKeyMode": "",

    "https://rism.online/api/v1#meiEncoding": "",
    "https://rism.online/api/v1#paeEncoding": ""
}

--in the json file, if the value within "" is blank, it means the property in the corresponding key cannot be reconciled (with Wikidata).

I will have a look next week and get back to you.

How is the URI <https://rism.online/api/v1#> generated?

This is just the namespace we assigned to our objects. It was generated from my head as a unique URI.

@prefix ns1: <https://rism.online/api/v1#>

This might make more sense if you do @prefix rism: <https://rism.online/api/v1#>

It doesn't change anything fundamentally, but it does mean you can make statements like <https://rism.online/institutions/30000440> a rism:Institution, which probably helps in the human-readability.

https://rism.online/sources/1000000001/holdings/51006604

Thanks, this is a bug. rism-digital/rism-online-issues#338

What does "Source contents" mean?

Source records in RISM can contain other Source records which are "children" of the parent. "Source contents" is a list of all the sources within the parent source record.

A "holding" record is the record that relates a book to its holding institution. In the case of printed books, there can be many holding institutions. In the case of a manuscript, there is only one. "Child" Source records in RISM do not have a holding record; only the parent records do.

[candlecao]

Thank you for sharing the context which helped me know better of RISM's structure.
