Restrict access to Content types

[asmita_hardikar]

Hello,

I have created custom content Model. I want ONLY SYSTEM ADMINISTRATOR to access certain content types:

E.g. I want only SYSTEM administrator to have access to "Administration guide" type of content.

Can this be done with Alfresco's content model?

How do I identify SYSTEM ADMINISTATOR group to define the permission model?

This should be very possible:

Check out  http://wiki.alfresco.com/wiki/PermissionModelDTD

The file that controls all default permissions is
    \WEB-INF\classes\alfresco\model\permissionDefinitions.xml

Study it - the snippet below shows you that permissions refer to different content types and aspects.

<!– An editor can read and write to the object; they can not create    –>
      <!– new nodes. They can check out content into a space to which they have       –>
      <!– create permission.                                                          –>
      <permissionGroup name="Editor"  expose="true" allowFullControl="false" >
          <includePermissionGroup type="cm:cmobject" permissionGroup="Consumer"/>
          <includePermissionGroup type="sys:base" permissionGroup="Write"/>
          <includePermissionGroup type="cm:lockable" permissionGroup="CheckOut"/>
          <includePermissionGroup type="sys:base" permissionGroup="ReadPermissions"/>
      </permissionGroup>
