Join GeoJson with additional info files

I have a GeoJson-file [1] with multiple polygons exported from OpenStreetMap that will be updated regularly and I want to add additional information (to the properties) from another file [2] (JSON ? I'm open for recommendations).

Every Object in the GeoJson-File has a ID that won't change when updated. So what kind of additional info file do a use and how do I join those based on the ID files?

[1]:

"features": [
    {
      "type": "Feature",
      "id": "way/3876802", //join based on this ID
      "properties": {
        "@id": "way/3876802",
        "barrier": "wall",
        "heritage": "4",
        "heritage:operator": "BLfD",
        "historic": "cemetery",
        "landuse": "cemetery",
        "ref:BLfD": "D-5-62-000-6"
      },
      "geometry": {
        "type": "Polygon",
        "coordinates": [
          [
            [
              10.9999265,
              49.5888688
            ],
            [
              10.9991467,
              49.5892462
            ],
            [
              10.9990158,
              49.5892965
            ]...

          "description": "Lorem ipsum dolor sit amet"
           ...}
