true swe:value
swe:Boolean swe:field
In the example above, the default value for the FusionAccepted parameter is true. It means that if the client does not specify a value, the server will automatically apply the
value true for this parameter.
7.1.2.1.2 Values of parameters embedded in tasking requests
Values of tasking parameters are encoded with any of the encoding defined in the SWE Common standard when embedded within a tasking request i.e. Submit, Update,
GetFeasibility, Reserve, etc.. A compliant EO SPS service implementation shall support at least the XML encoding method identified by the corresponding URI defined in the
SPS 2.0 standard.
Requirement http:www.opengis.netspecEOSPS2.0reqcoretasking-params-xml-encoding
Req 4. An EO SPS implementation shall support the XMLEncoding defined in clause
8.5 of [OGC 08‐094] “SWE Common Data Model 2.0 Encoding Standard” and pass
the corresponding conformance tests.
Please refer to [OGC 08-094] for details of the XML encoding rules. Annex C contains examples of tasking requests with the matching tasking parameters description.
As required by the SPS interface standard [OGC 09-000], any invalid value for a tasking parameter i.e. not matching the parameter definitions provided in
DescribeTaskingResponse shall result in an InvalidParameterException being sent back to the client.
7.1.2.2 ProgrammingRequest Class
7.1.2.2.1 Description
The ProgrammingRequest class is the root of the list of tasking parameters. It is abstract and cannot be instantiated. Instead, the CoverageProgrammingRequest class cf.
§7.1.2.4 or the SwathProgrammingRequest class cf. §7.1.2.5 are used.
Requirement http:www.opengis.netspecEOSPS2.0reqcoretasking-params-root
Req 5. The root of the list of tasking parameters in DescribeTaskingResponse shall
be a concrete instance of the ProgrammingRequest class.

7.1.2.2.2 Data model
This abstract class contains two common parameter groups that are inherited by its descendants. These groups are represented by the QualityOfService and
ValidationParameters classes, as shown in the UML diagram below:
«DataType»
ProgrammingRequest
«DataType»
QualityOfServ ice
«DataType»
Cov erageProgrammingRequest
«DataType»
ValidationParameters
«DataType»
Sw athProgrammingRequest
+QualityOfService 0..1
+ValidationParameters 1..
Figure 1 – UML diagram of the ProgrammingRequest class
Classes represented in this diagram are fully described in later sections: The class QualityOfService is specified in clause §7.1.2.3.
The class CoverageProgrammingRequest is specified in clause §7.1.2.4. The class SwathProgrammingRequest is specified in clause §7.1.2.5.
The class ValidationParameters is specified in clause §7.1.2.16.
7.1.2.3 QualityOfService Class
7.1.2.3.1 Description
This parameter group is used to specify the level of priority of the programming request. In general, the user should expect more reactivity from a ‘HIGH’ priority request than for
a ‘STANDARD’ priority request. However, he will usually be charged more in order to obtain this high priority service. The exact meaning of the priority levels have to be
agreed upon with the provider and are usually defined verbally in its terms of service. If the EO-SPS instance implements an authentication method, the internal priority level can
be defined on a per user basis by associating it to the user account.
