Andy, Lorne, Xizhi,

Let us design bag and item system here

Draft thought of Xizhi

Global Store

ID	int , Unique Indexed
PrimeKey	asset string key like url path Unique Indexed
FileID	nil, reference a remote paraworld file where this item can be downloaded safely
type	like AppCommand, APP, Model asset, texture asset, character asset, Bag, Item
category	virtual folder: like model/char, char/v3/assets. similar to PrimeKey. for human categorization.
Count	how many are left in store. nil for infinity.
Author	userID who uploaded
UploadDate	date
Icon	the icon to display. can be local or URL path.

编辑上传到Global Store的流程

Disk(Art Model browser) --> Scene --> Global Store (-->bag)

引入了一个Global Store, 好像是Template, 它可以被实例化到某个Bag中最多Count次, 每次实例化要消耗Price元。背包中的物品，好像是类的实例了。

Andy: my latest concern is the item system should be separated to two catrgories: traditional MMORPG like item system with official functions and model publishing systems that opens the user generated contents.
Xizhi: 我想分成的两部分，是否可以用GlobalStore中的Type来区分呢?

我是这样考虑处理MMO的物品，和UGC的物品的： Global Store 只记录上面写的内容。没有那些影响人物的属性等等参数。然后通过Type：每个Type有自己的表来描述各自的属性。比如MMO是一种表， UGC是一种表。甚至一些Type的属性表，可以每个Server独立维护的。 CentralAPI上只存GlobalStore一张很简单的表。可以满足显示( icon) 和交易(Price)。

注：这里将GlobalStore到官方的背包（商城）的过程也看成一种交易。比如我们在后台为每个Server的商城背包补充物品等。

背包的种类

：背包中的物品一般都是从GlobalStore中移入的
