🔬🦀 An experimental project to build a Rust package for RDF and Nanopublications with bindings to Python and JS (wasm)

🔬🦀 Nanopub rs

A rust toolkit to sign and publish Nanopublications, with bindings to python and javascript (wasm).

Nanopub signing process

• preliminary nanopub is created with blank space in URIs at the places where the trusty URI code will appear (normalized URI: http://purl.org/np/ARTIFACTCODE-PLACEHOLDER/, cf. code); this includes the signature part, except the triple that is stating the actual signature
• preliminary nanopub is serialized in a normalized fashion (basically each quad on four lines with minimal escaping)
• Signature is calculated on this normalized representation (cf. most of the process in the trusty-uri python lib, see also SignatureUtils and trusty-uri)
• Signature triple is added
• Trusty URI code is calculated on normalized representation that includes signature
• Trusty URI code is added in place of all the occurrences of blank spaces in the URIs, leading to the final trusty nanopub
