Is ESCAPE a funder or a project ?

The example codemeta file references the funder agency and funding grant.

"funder":[
    {
      "@type": "Organization",
      "name": "ESCAPE: European Science Cluster of Astronomy & Particle physics ESFRI research infrastructures",
      "funder": {
        "@type": "Organization",
        "@id": "https://doi.org/10.13039/501100000780",
        "name": "European Commission"
      }
    }
  ],
"funding": "824064"

As a new joiner using the example I have questions:

• Is the nested structure of funder Organization", inside funder Organization", correct ?

• Is ESCAPE a funding source in it's own right, or is it a project funded by the European Commission ?

• https://cordis.europa.eu/project/id/824064

• Is there any guidance on how to put something like this together ?
