Metabase Datatypes

4/8/2010

The OMA DM Format property is called a datatype in the metabase. The datatype specifies the node value.

The following table lists the datatypes.

Datatype Description

int

Integer. Whole number values. These values are translated by the OMA DM Data Process Unit (DPU).

chr or string

Character. Character datatype in OMA DM is equivalent to string datatype in OMA Client Provisioning, and is translated by the DPU.

bin

Binary. Binary as an octet stream. Often encoded as b64.

float

Floating point. This is a numeric floating point value.

> [!NOTE] > Float datatype is supported in Windows Mobile for OMA Client Provisioning protocol, but not for OMA DM protocol.

bool

Boolean. This value is translated by the DPU.

null

Null. An empty value.

node

An interior node.

b64

Base64 encoded. b64 is not a valid datatype in the Metabase. b64 is supported in OMA DM packages transmitted between client and the server. The b64 encoded data is stored in the device as binary datatype.

mchr

Multistring. Microsoft extended multistring datatype. MultipleString data type is treated as character format in OMA DM. Each string is terminated with Unicode 0xF000.

time

Time. The time format is ISO 8601 format. Both time only and the combination of date and time are supported. If the date + time format is used then a 'T' must appear between the date and time.

The following ISO 8601 time formats are supported:

  • UTC basic format: hhmmssZ
  • UTC extended format: hh:mm:ssZ
  • local time with time zone information- basic format: hhmmss+hh and hhmmss+hhmm
  • local time with time zone information - extended format: hh:mm:ss+hh and hh:mm:ss+hh:mm

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

date

A date. The date format is ISO 8601 format with the century being included in the year.

The following ISO 8601 date formats are supported:

  • basic format: YYYYMMDD
  • Extended format: YYYY-MM-DD

The supported date range is from January 2nd, 1753 to December 31st, 2078.
