Dynasties

Dynasties are organized like a tree, meaning that some periods are called by a name but they might include different dynasties.

For example: |123| 東晉[ Eastern Jin] (317 – 420) is part of the |1012| 晉[ Jin] (265 – 420) period

This means that when we look for people who lived during the |1012| 晉, we need to retrieve all people who lived during the child categories, including |123| 東晉.

We will have to do the same for semantic categories, which are also built as trees (larger categories parent of smaller categories).

This might have an impact on the xml version of ckp_slim. We can discuss it.
