Directory (Domain) Authorization
Because DSCloud Platform aims to provide services to thousand millions of users , how to control the authorization of the directories is very important. In DSCloud Platform , the user who creates the directory is the creator and owner of the directory. The owner can delete the directory when there are no joined users and no published articles in this directory. The owner can also trash the directory. The owner can set the authorization of the directory created by himself
Directory (Domain) AUthorization Policies and AUthorization Set
The authorization schema is a matrix in which column is as user’s role and row as the authorization. In the following figure, we defined five roles as DirCreator, thisGroup, grantGroup, grantUser, and Any User, and four rights as publish, Read, Create Sub Dir and Show Dir.
Four Rights:
Publish right means that the user who has the right can publish his articles( as well as attached files) in this directory.
Read right means that the user who has the right can read the articles in this directory.
Create Sub Dir right means that the user who has the right can create new sub directory in this directory.
Show Dir right means that the user who has the right can see this directory name.
Five Roles
DirCreator is the role the user has who creates the directory.
thisGroup is the role the user has who joined this directory(domain, sometimes we called as group) group.
grantGroup is the role the user has who joined the group granted by the owner.
grantUser is the role the user has who has been granted by the owner.
Any User is the role for any login users.
The DSCloud Platform checks the user’s right for these five roles. If any role among these fives with the right, and the user has the role , then the user has this right.
SET Users ROLES
Grant group the grantGroup role for the directory.
Grant user as the grantUser role for the directory.
Application management
