Hi Nuno and Andrea,
Thanks for following up. Yes I think the array would work nicely, and if it
used the maxOccurs attribute to determine if a property should be encoded as an
array it would bring the GeoJSON output more in line with the GML xml outputs.
<element ref="gml:name" minOccurs="0" maxOccurs="unbounded"/>
If it’s ok, I’ll create a ticket on JIRA. Hopefully others will also find it
useful or have other suggestions.
For a little more background, I’ve been using the app-schema name[1] mapping
syntax in our GeoSciML complex borehole service for the properties within the
data types that can’t really be feature chained, such as positionalAccuracy and
purpose. This works great for GML outputs, but GeoJSON encodes them as 1..1
taking only the last value so unfortunately not all the data is in the output -
Curiously though, following the 2.16 update the
gsmlbh:indexData/gsmlbh:BoreholeDetails/gsmlbh:purpose property is the only 1
to Many property to be encoded correctly as an array. See below
{
type: "Feature",
id: "gsml.borehole.205820",
geometry: {},
properties: {
@featureType:
"Borehole",
identifier:
"https://sarigdata.pir.sa.gov.au/resource/feature/gssa/borehole/205820";,
shape: {},
positionalAccuracy: {},
<--- [0..2]
referenceLocation: {},
indexData: {
@dataType: "indexData",
BoreholeDetails: {
@dataType: "BoreholeDetails",
operator: {},
driller: {},
startPoint: {},
inclinationType: {},
boreholeMaterialCustodian: {}, <--- [0..*]
purpose: [],
<--- [0..*] only one already outputting as an array
dataCustodian: {},
<--- [0..*]
boreholeLength: {}
}
},
downholeDrillingDetails: [],
logElement: []
}
}
Kind regards,
Ursula
