===Defining Spatial Data===
+
−
:Spatial Data input are passed to an algorithm using Well-Known Text format (WKT), i.e. a text markup language for representing vector geometry objects on a map, spatial reference systems of spatial objects and transformations between spatial reference systems.<ref>[https://en.wikipedia.org/wiki/Well-known_text "Well-known text"], ''[[Wikipedia]]''</ref>
+
−
:When an algorithm input is defined, a WKT input can be indicated by using proper annotations in the input descriptions. In particular, the annotations highlighted in red in the following table correspond to different geometries. For example a description for an input point could be "Location of an occurrence record [WKT_POINT]".

===Spatial Data on the DataMiner Interface===
+
−
 
+
−
:By using a specific widget, DataMiner is able to build a selection interface suited for the WKT input. This process is done by reading the annotation in the input description. The widget allows to easily select the area of interest and reports the WKT selected in a text area. In the end, the WKT string is passed to the algorithm:

===Temporal Data===
+
−
:Temporal Data are automatically interpreted using specific tags in the description of the inputs. The tags highlighted in red in the following table should be used to indicate the kind of temporal information to associate to the input. Currently, dates and time stamps are supported. For example a description for an input date could be "Date of the occurrence record [DATE]".
