What does こと mean between two nouns?


What is the function of the first こと in the following sentence?

「労働のビッグバン」こと非正規雇用の規制緩和が次々に行われたのは９０年代、バブルが崩壊して以降のことである。

Logically it seems it has a function similar to と. If that is indeed what it
does, does it have any other nuance?

If possible I would like to have a translation, or other examples of こと being
used this way.

This sentence appears in an article in 文藝春秋オピニオン２０１３年の論点.




As dainich said in the comment, this "AことB" just means "B also known as A" /
"B otherwise known as A". As can be seen in this example, A is normally a nick
name, a monikier, or a noun that may be unfamiliar to some readers, and B is
used to explain what A means.
