Namespaces¶
Namespaces are used to group objects unambiguously, so they can be addressed without confusion. They are used in several areas like XML and Object-oriented programming.
Example¶
Request¶
Try in your local Swagger
PUT /spaces/{spaceId}/features?addTags=mountain,canada
with the following body
{
"type":"FeatureCollection",
"features":
[
{
"type":"Feature",
"properties":
{
"name":"Baldy Mountain"
},
"geometry":
{
"type":"Point",
"coordinates":[-100.728, 51.4686]
}
}
]
}
Response¶
{
"features": [
{
"geometry": {
"type": "Point",
"coordinates": [
-100.728,
51.4686
]
},
"id": "HsOsZ0FXUI",
"type": "Feature",
"properties": {
"name": "Baldy Mountain",
"@ns:com:here:xyz": {
"createdAt": 1529855978032,
"space": "{spaceId}",
"tags": [
"canada",
"mountain"
],
"updatedAt": 1529855978032
}
},
"bbox": [

]
}
],
"type": "FeatureCollection"
}
When you upload a feature to XYZ Maps, XYZ automatically adds a property @ns:com:here:xyz to it. The following information is recorded in this property:
- createdAt - date and time the feature was created in milliseconds since 01.01.1970
- updatedAt - date and time the feature was updated in milliseconds since 01.01.1970
- space - random unique space ID, created at space creation, a string
- tags - the tags you added to the space, an array of strings
We use the namespace to store additional information in the object without interfering with the properties you provided.
