DataAvailable DataNotAvailable UnavailableCode DescribeResultAccess Operation

100 Copyright © 2011 Open Geospatial Consortium Requirement http:www.opengis.netspecSPS2.0reqDescribeResultAccessResponseidentification REQ 76. The service shall assign a unique identifier for each ReferenceGroup and the references contained in that group. Those identifiers shall not be changed while the according object reference group or reference exists. Note: thus for example a change to the set of references contained in a reference group does not change the identifier of this group.

7.3.8.8 DataNotAvailable

This data type expresses that no data is available. Requirement http:www.opengis.netspecSPS2.0reqDataNotAvailabledataType REQ 77. The DataNotAvailable data type shall contain the properties according to Table 48. Table 48 — Properties in the DataNotAvailable data type Name Definition Data type and values Multiplicity and use message human readable message that provides further information or reason why no data is available LanguageString, see clause 10.7 in [OGC 06-121r3] Zero or more optional Include one for each language represented unavailabl eCode identifies the reason why data is unavailable UnavailableCode, see clause 7.3.8.9 One mandatory

7.3.8.9 UnavailableCode

This type is a list of codes signifying the reason why result access information for a given task or sensor is not available. Copyright © 2011 Open Geospatial Consortium 101 Requirement http:www.opengis.netspecSPS2.0reqDescribeResultAccessResponseUnavailableCode REQ 78. The UnavailableCode code list shall contain the propertieschoices according to Table 49. Table 49 — Properties in the UnavailableCode code list Name a Definition Value DataNotAvailable Result access information is not available because no data has been published yet. “DataNotAvailable” DataServiceUnava ilable Result access information is not available because one or more of the services that are assigned to store the data gathered in a task is currently unavailable. “DataServiceUnavailable” a Although some values listed in the column appear to contain spaces, they shall not contain spaces. The code list is extensible. The pattern for new codes is the regular expression: other: [A-Za-z0-9_]{2,} However, for interoperability reasons a service should not use an arbitrary code that is not defined by an official SPS extension.

7.3.8.10 SPSMetadata

This data type provides SPS specific metadata for service references given in a DescribeResultAccessResponse. The SPSMetadata data type is derived from the OWS Common AbstractMetadata data type [OGC 06-121r3]. That data type does not define any property and thus SPSMetadata does not inherit any property from it. However, it is a child of AbstractMetadata and thus is a valid substitute whenever such metadata is provided, for example in references see clause 7.3.8.1.2. Requirement http:www.opengis.netspecSPS2.0reqDescribeResultAccessResponseSPSMetadata REQ 79. The SPSMetadata data type shall contain the properties according to Table 50. 102 Copyright © 2011 Open Geospatial Consortium Table 50 — Properties in the SPSMetadata data type
