different between using PrimitivePropertyBuilder and EpProperties in output strategy

Hi all,

I just created an output strategy and found two different ways to do so.

Either I use

.outputStrategy(

    OutputStrategies.append(

        PrimitivePropertyBuilder

            .create(Datatypes.String, "trajectory-wkt")

            .domainProperty("http://www.opengis.net/ont/geosparql#Geometry"<http://www.opengis.net/ont/geosparql#Geometry>)

            .build())

)


or





.outputStrategy(OutputStrategies.append(

    EpProperties.stringEp(

        Labels.withId(WKT),

        "trajectory-wkt",

        "http://www.opengis.net/ont/geosparql#Geometry"<http://www.opengis.net/ont/geosparql#Geometry>)

    )

)



What is the different between this 2 ways and which one should be preferred?

Greetings

Florian

Hi Florian,

in general, these are two different ways to achieve the same.
The builder provides more options to create non-mandatory properties (e.g., measurement units).
The EpProperties class contains convenience methods to describe event properties, so if you don't miss anything in this class, you can use this one. In case you need advanced settings that are not provided here, you can switch to the PrimitivePropertyBuilder.
