Wikidata talk:WikiProject Periodicals
Journal/Periodical data from "KBPlus"
Over the last few years I have worked with a UK based service called KBPlus/KB+ run by Jisc (Q6269240). This collects information about journals/periodicals that are subscribed to by UK Universities. It publishes lists of journals under a CC0 licence. The data made available typically includes ISSNs (and sometimes other identifiers), a textual note on relationships between journal titles (e.g. "preceded by: old title, continued by: new title"), plus information on where you can subscribed to it (or if it is open access). My involvement with the project has been on the technical side rather than on the data side, but I know they have a small team of staff who are responsible for ensuring the accuracy of the data in the system, so I have confidence that the data in the system is well maintained and generally accurate.
I'm wondering if there would be any interest in using the data from KB+ to either create new records in Wikidata (where the journal doesn't already have a wikidata entry), or adding data to existing wikidata entries. I've done some initial work and KB+ holds information on approximately 268.5k journal titles. I've matched about 48k of these to existing wikidata entities based on the ISSN.
Is the state of the description for issues outdated
In the isse section it says to use P364 but the examples use P2439 instead (which makes more sense to me).
It also states to use properties P433 and P478 but in the examples P478 is use as a qualifier for P433. The latter is not useful for issues where the it is unknown when the first one got out. I also found examples where P478 is a qualifier for P361 which somehow makes more sense to me.
Importing all articles from the EFSA journal
The EFSA journal is an open-access publication by the European Food Safety Agency. It has periodic evaluations of food additives, and it would thus be very useful to link those articles to the food additives that exist in Wikidata, paving the way for sourced recommandations in outside projects like Open Food Facts.
I have no idea how the import of periodicals is done in Wikidata. Is that a request for titles ? Does it require tedious work ?
