Using tags for data driven style

[hugosoli]

Hi I want to have a Theme that has some data drive style. I upload a geojson with the Data Hub CLI and it works fine. One tag was authomatically generated from the file name

id │ geometry.type │ tags │ createdAt │ updatedAt │
├─────────────────────────┼─────────────────────────┼─────────────────────────┼─────────────────────────┼─────────────────────────┤
│ p7RjANTPCd776Wez │ Polygon │ coloniascdmx │ 10/24/2021, 06:46 AM │ 10/24/2021, 06:46 AM

I have tries several option at the style description. for example:

{//colonias
description: "GeoJson polygon",
when: [
"all",
["==", ["geometry-type"], "Polygon"],
["==", ["get", "@ns:com:here:xyz.tags[0]"], "coloniascdmx"],
],
technique: "fill",
attr: {
color: "#10",
lineColor: "#FF000010",
lineWidth: 1
}
}

The object sees to have such feature:

userData:
$geometryType: "polygon"
$id: "yaMmk6oT6U4MECC3"
$layer: "NUcQuJnH"
$level: 13
$zoom: 14
@ns:com:here:xyz: "{"tags": ["coloniascdmx"], "space": "NUcQuJnH", "createdAt": 1635075994241, "updatedAt": 1635075994241}"

Any idea or help?
Cheers and thanks

@hugosoli , does something like: ["in", ["get", "tags", ["get", "xyz"]], "coloniascdmx"] work?

You can use the get syntax to return an object, which you can then query for the tags property, see: https://github.com/heremaps/harp.gl/blob/master/@here/harp-datasource-protocol/StyleExpressions.md#get

Ok, what does the geojson look like after you have uploaded it to here? Do you have some sort of sample? I was hoping to have have the date with the tags like you mentioned, so I could try it locally. Is that possible?

I'm away Friday, so maybe I can only take a look on Monday sorry.

Hi, sorry for bothering. I am still fighting with this issue. Any recommendation?

@hugosoli , can you download the geojson from the xyz and see how it is stored?

[hugosoli]

hi!
I don't know exactly how to download the geojson but I guess It can be done with the CLI as follow:

here xyz show IjL4qOrm -r > alltogether.geojson
with that I get a gejson that has all the points with the properties. One element for example is:

{
"id": "Lo2giU3wakmaI9Gm",
"type": "Feature",
"properties": {
"id": 1221,
"categoria": "Plazas y jardines",
"subcategoria": "Jardines públicos",
"@ns:com:here:xyz": {
"space": "IjL4qOrm",
"createdAt": 1635278264923,
"updatedAt": 1635278264923
}
},
"geometry": {
"type": "Point",
"coordinates": [
-99.10662628,
19.31315855,
0
]
}
},

INTERESTING! There is nothing related with the tags on it. That could be the reason why I can not get it, howerver, the tags values should be somehwere because they apear on the userdata once it is downloaded
