OMA DM Standards and Extensions

Windows Mobile 6.5
4/8/2010

The following table shows the OMA standards that Windows Mobile uses.

General area OMA standard that is supported

Data Transportation and Session

  • Remote DM server initiation notification using WAP Push over Short Message Service (SMS).
  • Remote bootstrap by using WAP Push over SMS.
  • Remote HTTPS DM session over SSL.

Bootstrap

  • WAP profile (with the exception of OMA Client Provisioning XML OTA bootstrap message).

DM protocol commands

The following list shows the commands that are used by the device:

  • Add (Implicit Add)
  • Alert (DM alert): server-initiated mgmt alert (1200), session abort (1223)
  • Atomic
  • Delete
  • Exec
  • Get (For interior nodes, the child node names in the Data element are returned in URI-encoded format.)
  • Replace
  • Result
  • Sequence
  • Status

For more information about these commands, see OMA DM Protocol Command Elements.

If an XML element that is not a valid OMA DM command is under one of the following elements, the status code 400 is returned for that element:

  • SyncBody
  • Atomic
  • Sequence

If no CmdID is provided in the DM command, the client returns blank in the status element and the status code 400.

If Atomic elements are nested, the following status codes are returned:

  • The nested Atomic command returns 500.
  • The parent Atomic command returns 507.

For more information about the Atomic command, see OMA DM Protocol Command Elements.

The security check for the Add command is done at the child level. This is because access rights can be pre-assigned to nodes that are not created.

LocURI cannot start with "/".

Meta XML tag in SyncHdr is ignored by the device.

OMA DM standard objects

  • DevInfo
  • DevDetail
  • OMA DM Server Account (DMAcc) object (OMA DM version 1.1.2)
  • OMA DM DMS account objects (OMA DM version 1.2)

Security

  • Authenticate DM server initiation notification SMS message
  • Application layer Basic and MD5 client authentication
  • Authenticate server with MD5 credential at application level
  • SSL at transport with certificate-based server authentication

E-Mail Notification

Windows Mobile 6.5 is compliant with the OMA E-Mail Notification (EMN) specification V 1.0 as set forth in "OMA-TS-Push_EMN-V1_0-20071019-A."

  • The required mailbox attribute is recognized to determine which mail account to synchronize.
  • The optional timestamp attribute is ignored.

Format

  • MultipleString data type is treated as chr format in OMA DM. Each string is terminated with Unicode 0xF000.
    For more information, see Metabase Datatypes.
  • When you query a time format node, the Universal Time (UTC, also known as GMT, or Greenwich Mean Time) format is returned regardless whether it is created or replaced with UTC or local time that includes time zone information.
  • Microsoft has extended the datatypes with the following additions:
    • time
    • date

Nodes

In the OMA DM tree, the following rules apply for the node name:

  • "." can be part of the node name.
  • The node name cannot be empty.
  • The node name cannot be only the asterisk (*) character.

For more information about nodes, see OMA Device Management Tree.

Provisioning Files

If an XML element that is not a valid OMA DM command is under SyncBody, the status code 400 is returned for that element.

The Device ID used in SyncHdr LocURI and DevID in the DevInfo object is an application-specific global unique device identifier.

Bb737228.note(en-us,MSDN.10).gifNote:
To represent a Unicode string as a URI, first encode the string as UTF-8. Then encode each of the UTF-8 bytes using URI encoding.

The following list shows the custom properties that Microsoft has added:

Property Description

AccessRole

Defines the access role for a node. For information about the possible security roles and corresponding role values, see Security Roles.

RWAccess

Defines read/write permissions. This is translated to rw-access in the metabase. For more information, see Metabase and OMA DM.

MaxValue

Defines the maximum value a leaf node integer value, defined in int format. For more information, see Metabase and OMA DM.

MinValue

Defines the minimum value a leaf node integer value, defined in int format. For more information, see Metabase and OMA DM.

MaxLength

Defines the maximum size of a leaf node text value. For more information, see Metabase and OMA DM.

Multiple

Defines whether the user can select multiple options. For more information, see Metabase and OMA DM.

The following table shows how Microsoft extended other OMA DM standards.

Standard Extension

Bootstrap DM account using the OMA Client Provisioning w7 APPLICATION characteristic

Added the role element under the APPLICATION characteristic. For more information, see w7 APPLICATION Configuration Service Provider.

DDF

Extended the DDF files to include Microsoft custom property descriptions.
