Extract Date Part

Extracts date parts (Year, Month, Day, ...) as integers and strings

• SOURCE [OBJ]: a list of objects

• PAIR [OBJ,INTEGER]: for each object in the input source the extracted integer value is provided as the second column in [OBJ,INTEGER]. When multiple values can be extracted for an object, each object-value pair is returned as a separate result.
• RESULT [INTEGER]: the extracted values, disjoint from their parent object. Use the score aggregation parameter to define how occurrences of the same values are handled.
• SPAIR [OBJ,STRING]: same as PAIR, but with values as strings
• SRESULT [STRING]: same as RESULT, but with values as strings

• Property: the property to extract the values from. Use * to extract values from all properties
• Use sub-properties: when set to true, the values of all sub properties are also included. Sub-properties can be defined in the data with the rdfs:subPropertyOf relation.
• Part: The date part to extract

Output scores can be aggregated and/or normalized.
