Charles Alston is one of the artists who are of interest to the Black Lunch Table. Mr Alston died in 1977. One of his struggles was to have his art appreciated in the same way as any other art. It is why he refused to be exhibited in William E. Harmon Foundation shows, which featured all-black artists in their travelling exhibits. Alston and his friends thought the exhibits were curated for a white audience, a form of segregation which they protested. They did not want to be set aside but exhibited on the same level as art peers of every skin color.
Today is 2017 and the BLT addresses this black experience and gains the same attention for black artists by writing in Wikipedia about them. It is why many artists with a black experience gain more information in Wikidata, artists like Mr Alston. The one thing where Wikidata differs from Wikipedia is that it is all about connections. The more a person is connected, the more relevant in different settings. Mr Alston had a notable spouse, he was a founder and member of an art group, he studied and worked. All these things are easy and obvious in Wikidata.
From an artists point of view, other things are of relevance too; what awards did he gain, what museums have work in their collection and where did he exhibit. There is yet no obvious way how to make such a claim. Like so many young men of his time, he was in the army in the 372nd Infantry Regiment but that is not quite what Mr Alston is about. This could be relevant for people who care about the military and also, the 372nd was a black experience as well.
Most articles on the English Wikipedia for a person have categories about education, work at a faculty. Adding the implied information for everyone is almost as easy as adding it for one person. It makes adding statements something of a black art, an art that looks complicated an art that connects everything.
