RDFox访问视图

Question

我可以使用 RDFox 版本 3 设置对知识图的仅查看权限吗？（无编辑）

我想创建不同的用户角色并控制谁可以 see/edit 什么权限，直至三重级别。

Answer 1

是的，使用访问控制功能，您可以为用户分配角色和授予权限，例如，您可以将用户的权限限制为只能查看。

例如，您可以使用 role 命令和 create 子命令来创建新用户：

role create user1
Enter the password for the new role:
Confirm the password:    
A new role was created with name "user1".    
role create group   
Enter the password for the new role:    
Confirm the password:    
A new role was created with name "group”.

然后可以授予权限，例如：

> grant privileges read,write,grant >datastores|* to user1    
The privileges 'read,write,grant' over resource specifier ">datastores|*" were granted to the role "user1" (if not already present).

或者您可以撤销权限，例如：

> revoke privileges write,grant >datastores|* from user1    
The privileges 'write,grant' over resource specifier ">datastores|*" were revoked from the role "user1" (if they were present).

如果您随后使用 show 子命令，您可以看到用户拥有的角色和权限：

> role show user1

'user1' has the following directly assigned privileges:

  Resource specifier |  Allowed access types   

  >datastores|*      |  read

这导致了用户的只读权限。
