A simple spatial data definition generating name and label attributes based on the column

Code Block
languagexml
<data:datadefinition id="graffiti">
	<spatialdataconnection entity="graffiti">
		<parameter column="ID"/> <!-- name will be 'id', label 'Id' -->
		<parameter column="DESCRIPTION"/> <!-- name will be 'description', label 'Description' -->
		<parameter label="Created on" column="CREATED" type="datetime"/> <!-- name will be 'created' -->
		<parameter label="Modified on" column="MODIFIED" type="datetime"/> <!-- name will be 'modified' -->
		<parameter name="user" label="User" column="USERID"/>
	</spatialdataconnection>
</data:datadefinition>


A simple example that points directly to a table, and therefore does not require its own entity and spatial mapper

Code Block
languagexml
<data:definition id="graffiti">
  <spatialdataconnection spatialengine="gis" table="GRAFITTI" key="ID">
    <parameter name="id" label="Id" column="ID"/>
    <parameter name="description" label="Description" column="DESCRIPTION"/>
    <parameter name="created" label="Created on" column="CREATED" type="datetime"/>
    <parameter name="modified" label="Modified on" column="MODIFIED" type="datetime"/>
    <parameter name="user" label="User" column="USERID"/>
  </spatialdataconnection>
<data:definition>
