I am Roderic D. M. Page (Q7356570), you can find me on Twitter as @rdmpage, and I have a blog iPhylo which lists my current projects.


How to add references Help:Sources



See User:Succu/SPARQL for lots of relevant examples.


See Help:Deprecation. One example of using this would be to correct dates of articles where CrossRef has got the date wrong (e.g., Wiley metadata).


Trying to clean up Zootaxa, first example The type specimens of Tachinidae (Diptera) housed in the Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”, Buenos Aires (Q29469527) and The type specimens of Tachinidae (Diptera) housed in the Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”, Buenos Aires (Q35800184)

Problem is that Revision of the neotropical Exoristini (Diptera, Tachinidae): the status of the genera Epiplagiops and Tetragrapha. (Q35950285) cites both, but they are not merged in that references list of cited works.

I got bored and manually fixed the duplication.

Another test case: Revision of Zorion Pascoe (Coleoptera: Cerambycidae), an endemic genus of New Zealand (Q79429489) and Revision of Zorion Pascoe (Coleoptera: Cerambycidae), an endemic genus of New Zealand (Q28939048), where one has CrossRef DOI and is cited by A checklist of New Zealand Cerambycidae (Insecta: Coleoptera), excluding Lamiinae (Q56166058), the other has Zenodo DOI, has authors instead of author strings, and is linked to a taxon Zorion taranakiensis (Q14848194).

To add references for a statement in Wikidata using Quickstatements:

Q36504420 P21 Q6581072 S248 Q28948401

Note "S" instead of "P" for "stated in" property. To see the result in Wikidata see Andreja Kofol-Seliger (Q36504420).




Lots have been uploaded to Wikicommons by various museums, often unconnected to anything else.


Authority control[edit]

Authority control


Wikidata:List of properties/geography

Can store GeoJSON in Wikicommons, e.g. Commons:Data:BioStor/ Need to create page manually then add data (create page via a red link).

Can link to Wikidata using geoshape (P3896) View with SQID

Need to figure out how to retrieve GeoJSON for use in applications.
