At this time of year it is very popular to try to predict what will happen in the next year, being 2013, within your field of expertise.
However, predictions, not at least about the future, may fail. And within data quality we don’t like flaws. So instead I will tell a little bit about what happened in year 1013 with respect to data quality.
As always Wikipedia is your friend when seeking knowledge. So I have picked a few of the highlights from the Wikipedia article about 1013:
Diversity
In 1013 the Viking warlord Sweyn Forkbeard replaced Æthelred the Unready as King of England. These were the happy days when the letter Æ was part of the English alphabet. Today Æ only exists in some of the Viking alphabets.
Definition
Kaifeng, capital of China, becomes the largest city of the world in 1013, taking the lead from Córdoba in Al-Andalus. However this is estimation. And even today, as reported by BBC, we actually can’t tell which one is the largest city in the world.
Multiple versions of the truth
The anti-pope John XVI dies in 1013. An anti-pope is a person who, in opposition to the one who is generally seen as the legitimately elected Pope, makes a significantly accepted competing claim to be the Pope. Even today we can’t always establish a single version of the truth.
