Example

Let’s say you have a directory with one file in it, which you want to document. Here’s how you could make an RO-Crate using RdfCrate:

from rdfcrate import AttachedCrate, uris
from rdflib import Literal

crate = AttachedCrate("/path/to/crate")
crate.register_file("salvatore.jpg", [
    (uris.name, Literal("Salvatore the Seal"))
])
print(crate.compile())

{
  "@context": "https://w3id.org/ro/crate/1.1/context",
  "@graph": [
    {
      "@id": ".",
      "@type": "Dataset"
    },
    {
      "@id": "salvatore.jpg",
      "@type": "File",
      "encodingFormat": "image/jpeg",
      "name": "Salvatore the Seal"
    },
    {
      "@id": "ro-crate-metadata.json",
      "@type": "File",
      "about": {
        "@id": "."
      },
      "conformsTo": {
        "@id": "https://w3id.org/ro/crate/1.1"
      },
      "encodingFormat": "application/json"
    }
  ]
}
