This error happens when your Extension file is put on a server that blocks other servers from downloading/accessing the file.

The simplest solution is to put it on another server, GitHub allows others to use the files, so just create a repository, put the Extension there and link to it.

Be careful, you need to link to the "raw" version:

I realised that when there is an error in a CityJSON file, cjval only outputs the error and not the warnings about that file. Only when the error is fixed, the warnings are outputted. Wouldn't it be better if it was possible to see both errors and warnings at the same time?

I am trying to map this part of Energy ADE to CityJSON where DHWFacilities, ElectricalAppliances and LightingFacilities inherit from Facilities, and they are all extraCityObjects.

To reference Facilities in DHWFacilities object, I tried adding the line below:

"+DHWFacilities": {
      "allOf": [
        { "$ref": "#/extraCityObjects/+Facilities" },
        ...

But when I validate it with cjval, I get the error below:

Hello, it looks likes that the validator only checks for unused vertices of type "MultiSurface", "CompositeSurface", "Solid", "MultiSolid" and "CompositeSolid".
Is there any reason not to include also "MultiPoint" and "MultiLineString"?
This is would helpful when using extensions.

When processing a large file, It is unclear if the program is actually doing anything, untill the chrome / firefox popup of "this webpage is slowing down your browser". This could be fixed by introducing web workers (offloading the process to a different thread), and by adding a small indication to tell the user that the program is running.

Hi, I am trying to use the validator (cjval: a validator for CityJSON files) to validate my CityJSON models schema. However, it seems like the validator can only support CityJSON v1.0 or v1.1 schema.

My CityJSON model is converted from the FME. It seems like FME only support CityJSON v1.0.1 schema?

May I ask is there any solution so that I can use your CityJSON?

Thank you very much.

version: 0.5.0
os: ubuntu 22.04
command: cjval tmoaf.city.json || echo "error"

This prints "error" at the end, which is only printed if the return code is non-zero (in bash).

I think cjval should return 0 if it manages to validate a file, regardless if the valid or invalid. It should only return non-zero if cjval cannot run for some reason.

The file is from https://github.com/cityjson/themotherofallfiles

I am trying to create an extraCityObject as follows:

"+UsageZone": {
      "allOf": [
        {
          "$ref": "cityobjects.schema.json#/_AbstractCityObject"
        },
        {
          "properties": {
               ...
           },
          "additionalProperties": false
         }
      ]
}

I thought that I did not need to add extra "parents" and "children" properties since these are already defined in _AbstractCityObject, but I guess because I included additionalProperties: false, cjval gives an error when I try to use parents/children properties in my json file.

Could this be caused by the validator itself?

When adding an "address" to a building, cjval 0.4 throws an "unused vertices" error in case the address has a "location" property containing a "MultiPoint" geometry. The error is thrown for both CityJSON 1.0 and 1.1 datasets.

now only for the geometries and "vertices" this is done

to avoid this in the future: #10
