The MCData message store allows an MCData user to deposit his MCData communication information (i.e. messages or files) securely and permanently for later retrieval. During an active MCData communication, a message or a file with its associated metadata is deposited as an object in the MCData message store with an object identifier; this object identifier enabling a direct access to that object. The objects in the MCData message store are managed from both the MCData server and the message store client.
Each MCData user is allocated a dedicated and secured storage area (i.e. with a user account) in the MCData message store. All MCData communications of a MCData user can be stored in his dedicated storage area. The access to this secured storage area is possible only after successful authentication and authorization procedures. A message store client can create a local copy of the stored objects into the device by synchronizing with the MCData message store for the MCData user using the device.
As illustrated in Figure 7.13.1 all MCData user storage areas are accessed only through the common root. The authorized MCData user shall only have the access to the MCData user's storage area after the successful authentication and authorization procedures. A MCData user shall not be able to access objects stored for other MCData users.
The MCData user shall manage his stored objects using message store client through the MCData-7 reference point. The MCData server shall use the MCData-8 reference point to deposit MCData communication information, during an active MCData communication, into the designated MCData user's storage area in the MCData message store.
One way to manage user stored objects is using folder hierarchy structure like the popular email system today. Annex D provides a simple example of how it will look like in deployment. When the user account is created in the MCData message store, a default folder (such as Inbox) is also created to capture all the objects during an active communication. To group relevant stored objects together and provide easier navigation interactively, a MCData user can create folders in his user account. Each folder is identified by its unique folder identifier that is composed with the location of the folder and the name of the folder. A folder may have child folders to further group the stored objects in more meaningful ways. For example, the folder identifier of the default Inbox folder is /MCDatamessagestore/MCDatauser1/Inbox. The folder identifier /MCDatamessagestore/MCDatauser1/Squad1/20190225 points to a folder named 20190225 which is a child folder of Squad1 folder in the MCData user1 user account.
The MCData message store shall authenticate the credential of MCData server or the authorized MCData user before authorizing access to the MCData user's storage area. The success of authentication and authorization shall allow access to that MCData user's storage area only.
The stored object identified by the object identifier in the request. This information element shall be returned as empty when there is no stored object can be identified by the object identifier in the request
