SenosrNet.xsd v0.01 2005-03 SensorNet Feature schema. This is the base feature type for all features in SensorNet. All other SensorNet features are derived from snet:Feature. snet:Feature may also be used itself to insert generic data into SensorNet. This is a read-only attribute. All features are versioned and the versioning is maintained automatically by the WFS. By default, all new features have a version equal to 1. This element contains either a GML Point or GML Box describing the basic location for this feature. More complex geometries may be supplied in additional feature properties. This element contains either a GML TimeInstant or GML TimePeriod describing the basic temporar properties for this feature. More complex temporal properties may be supplied in additional feature properties. This property gives the ID of the data center where the feature is first inserted. If left empty, the WFS at the data center will populate the property with it's ID. This property is the fully qualified functional label categorizing the feature. It is recommended that functional labels follow the suggested naming guide located at . For inserts and queries, the WFS uses the user's role to determine if they can read/write the feature based on the functional label. This property is optional, but may be used to associate this feature with another snet:Feature. The value of this property should be the feature ID of the feature it is associated with. This property is optional, but may be used to label the feature with it's owner. If labeled, the user responsible for managing the owner label is then responsible for maintaining access control rules to allow the appropriate users to view this feature. This property gives the sensitivity level (PUBLIC, OUO, etc) for this feature. This property gives the DN of the certificate presented when the feature is inserted. This property is read-only and is generated automatically when the feature is inserted. Contains the actual data readings for this observation or contains the observation(s) related to this feature. Feature type representing a logical grouping of other features. The geometric properties of this feature should describe a general area of interest for this group. It is not required to be a superset of the geometries for all features in the group. Descriptive (verbose) name of this logical group. Compact format ID of this logical group. (i.e. useful for labeling icons) Feature type representing a physical node. The geometric properties of the feature should describe the location of the node itself, not necessarily the location of all sensors reporting to the node. Feature type representing a physical sensor. Feature type representing a data source. The geometric properties of the feature should describe either the actual location of the data source itself or an area representing the coverage of the data. Descriptive (verbose) name of this data source. Compact format ID of this data source. (i.e. useful for labeling icons) Gives the type of this data source. Indicates if this is a mobile or fixed data source. true indicates the node is mobile, false indicates fixed. Indicates the operational status of this data source. Verbose description of any deployment specific notes. These notes may include access restritions, driving directions,etc. Gives name and contact information for the point of contact for this data source. Gives the manufacturer of this data source. Gives the model of this data source. Gives additional meta data properties about this data source. Feature type representing an observation from a sensor or other data source. A verbose description explaining what is being observed, how the observation was made, what the result means, etc. Feature type representing an event. Gives the type of this event. A message associated with this event. The event message should be formatted as a CAP message. Feature type representing an alert.
