To attempt to answer your question Ziyi, the main Kaifeng page will touch on all the periods of its history. Yin, the last capital of the Shang is already in the works for a district, as is the much later Jewish Quarter. Whatever else there will be of it will evolve as we work on it. Every era does not have to be represented by a separate district. Those not having a special district can be explored through articles and discussion boards.

If you are interested in the Song era, that might be what you'd want to do with the Imperial Quarter. Or perhaps an in depth study of imperial life and customs throughout Kaifeng's history. *S*
