B.4 Mapping UML Data Types to XML Schema

29.198-013GPPOpen Service Access (OSA) Application Programming Interface (API)Part 1: OverviewRelease 9TS

B.4.1 Data Types

The following mappings apply to the basic data types:

UML

Schema Realisation

TpBoolean

xsd:boolean

TpInt32

xsd:int

TpInt64

xsd:ong

TpFloat

xsd:float

TpOctet

xsd:unsignedByte

TpString

xsd:string

TpLongString

xsd:string

TpAny

xsd:anyType

B.4.1.2 <<Constant>>

The UML Constant data type contains the following attributes:

  • Name
  • Constant Value

These types are not mapped to WSDL, as there is no concept of a constant value in schema. It may be possible in the future to add a constant value using a restriction on a base type. The lack of this mapping does not limit the ability to send constant values in messages.

B.4.1.3 <<NameValuePair>>

The UML NameValuePair data type contains the following attributes:

  • Name
  • Attributes
  • Name

This type would then map to the following XML Schema construct:

<xsd:simpleType name=”Name”>

<xsd:restriction base=”xsd:string”>

<xsd:enumeration value=”Attribute-Name” />

<xsd:enumeration value=”Attribute-Name” />

…

<xsd:enumeration value=”Attribute-Name” />

</xsd:restriction>

</xsd:simpleType>

B.4.1.4 <<SequenceOfDataElements>>

The UML SequenceOfDataElements data type contains the following attributes:

  • Name
  • Roles
  • Name
  • Type

This type would then map to the following XML Schema construct:

<xsd:complexType name=”Name”

<xsd:sequence>

<xsd:element

Name=”Role-Name”

type=”Role–Type” />

<xsd:element

Name=”Role-Name”

type=”Role–Type” />

…

<xsd:element

Name=”Role-Name”

type=”Role–Type” />

</xsd:sequence>

</xsd:complexType>

B.4.1.5 <<TypeDef>>

The UML TypeDef data type contains the following attributes:

  • Name
  • ImplementationType

Type definitions (typedefs) do not exist directly in schema so these types are unwound to their base data types. E.g.:

UML

Schema Realisation

TpCallAlertingMechanism

xsd:int

TpAccessType

xsd:string

This support could be added in the future using restriction on a base type.

B.4.1.6 <<NumberedSetOfDataElements>>

The UML NumberedSetOfDataElements data type for sequences types contains the following attributes:

  • Name
  • ImplementationType

This type would then map to the following XML Schema construct:

<xsd:complexType name=”Name”>

<xsd:sequence>

<xsd:element

name=”item”

type=”ImplementationType”

minOccurs=”0”

maxOccurs=”unbounded” />

</xsd:sequence>

</xsd:complexType>

B.4.1.7 <<TaggedChoiceOfDataElements>>

The UML TaggedChoiceOfDataElements data type contains the following attributes:

  • Name
  • SwitchType
  • Roles
  • Name
  • Type

This type would then map to the following XML Schema construct:

<xsd:complexType name=”Name”>

<xsd:sequence>

<xsd:choice>

<xsd:element name=”Role-Name” type=”Role-Type” />

<xsd:element name=”Role-Name” type=”Role-Type” />

…

<xsd:element name=”Role-Name” type=”Role-Type” />

</xsd:choice>

</xsd:sequence>

</complexType>
