|
|
The element <SamplingUnit> contains raw sample data for a specimen. <SamplingEvent> contains information about where and when that sampling occurred.
|
|
<p />
|
|
A simple SDD instance document representing a sampling event has the basic structure shown below and in example 4.5.1.1.

|
<DateTime> records the date and time when the sampling event occurred, either as a single time point or as the start of a time period.
|
|
<p />
|
|
<DateTimeSpanEnd> records the end of a time span if event timing is recorded as such.
|
|
Both date/times may be incomplete in ways not expressible in xs:datetime, e.g. the day and year may be known, but month unknown.
|
|
<p />
|
|
<GeographicArea> is a reference to a geographic area at which the event occurred. This is defined in the element <GeographicAreas> with the basic structure shown below and in example 4.5.1.2.

<Coordinates> records a point on earth at which the event occurred. Elements available are <Latitude>, <Longitude>, <GeodeticDatum>; <Verbatim> (a textual representation of the original location data) and <Literal> (a free-form string in addition to or instead of numeric coordinates (i.e. Charley's Creek, near Chinchilla).

|

<p />
|
|
A sampling unit may be an individual organism, a leaf of a tree, a piece of tissue, etc. In each sampling unit multiple characters may have been observed together ('paired observations'). Example: 'leaf shape, length, and width' of a single leaf). Value frequencies (e. g., '2.3': observed 4 x) are not supported; they are useful when only a single character variable is supported, but complicate paired observations unnecessarily. Char. values with a frequency should be entered in repeated SamplingUnits.

A simple SDD code snippet representing part of the sample data above has the basic structure shown below and in Example 4.5.2.1.
