Mr Bookasta has an article on the English Wikipedia. Until recently there was no item for him on Wikidata. With a new tool by Magnus, the Creator, items were added for all articles that are in the categories of people who were born or who died after 1850.
Since then two inter language links were added for Mr Bookstra. Thanks to a query we can track who is added to the category of 2014 deaths and are not known to be dead in Wikidata.
As all the people who died in 2014 have their deaths noted, it is only a matter of keeping up. The article for Mr Bookstra is small but includes many bits of information that can be added to Wikidata. One thing that I did not add is that he was also a bigband leader.
