Hi,
I'm about to import around 7,000 P2347 mappings (YSO ID authority links) between Wikidata items and YSO (General Finnish Ontology) concepts to Wikidata using QuickStatements2. I'm following the excellent example of Joachim Neubert's work at ZBW, documented e.g. here: http://zbw.eu/labs/en/blog/wikidata-as-authority-linking-hub-connecting-repe...
The mappings were collected from several sources: 1. Mappings between KOKO (related to YSO) and Wikidata curated by the Finnish Broadcasting Company Yle (kindly given to us, but not publicly available AFAIK) 2. Indirect mappings derived from Wikidata-LCSH and YSO-LCSH mappings 3. Algorithmic matching suggestions for frequently used YSO concepts
In all these cases, the mappings have been verified by vocabulary managers here at the National Library of Finland, so we're not just blindly copying the information from the above sources.
I'm wondering about whether to add source/qualifier statements to the mapping statements I'm about to add. I see that in most cases, authority links don't have any source information. For this batch, I could potentially document several bits of provenance information:
1. Where the (suggested) statement originally came from (e.g. Yle and/or indirect LCSH mapping) 2. That we have verified it here at NLF
I see that Joachim used source statements like this for his imported links:
title (P1476): Derived from ZBW's RAS-GND authors mapping (English)
reference URL (P854): https://github.com/zbw/repec-ras/blob/master/doc/RAS-GND-author-id-mapping.m...
Is this still best practice or should I use something else? Or just import the raw links without any qualifiers or sources?
Thanks in advance, Osma
