So I did all the usual things to find out:
- I googled
- I went to the library
- I blogged about it
- I asked on Facebook in a SIG with many people from Morocco
When you are adding statements to Wikidata, it helps when you can can get satisfaction out of the visualisation of the facts. Moulay Hicham exists at this time only in Wikidata, t would be good when be showed as a "red link" as there is no article in any Wikipedia about him. i
When you add data on subjects that have their basis in Africa, you will find that the information in Wikipedia is spotty and that it is very much seen from Western eyes. I am for instance not convinced that Morocco was a sultanate. He is called Moulay Hicham and Wikipedia makes "moulay" equal to "Prince". The current "King" is actually a "Malik".. I do not know enough so I remain puzzled.
