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())
