Context

The shared YAML-LD context for nanopub authoring in this site is:

https://nanopublishing.iolanta.tech/context/v0.yamlld

Overall Skeleton

"@context": https://nanopublishing.iolanta.tech/context/v0.yamlld

$nanopublication:
  $assertion:
    # Assertion: what do we want to say?
    - $id: something
      is: kind of anything

  # Provenance: on which grounds do we assert the above? On whose authority?
  prov:wasAttributedTo: https://some-important-international.example.org

# Top Level: what can we say about the whole publication that we're writing?
npx:supersedes: URL of a previous publication

this:

this: is the local prefix for entities defined inside the current nanopublication. In the shared context, it expands to the nanopublication's own namespace, so this:MyEntity means "the resource MyEntity in this nanopublication".

Use this: when you need a local identifier that belongs to the nanopublication you are writing, for example when the nanopublication introduces or embeds a new entity. Use an external IRI such as wd:Q319 when the entity already exists elsewhere.

$nanopublication:
  $assertion:
    - $id: this:MyEntity
      rdfs:label: My entity

npx:introduces: this:MyEntity

$nanopublication level

prov:wasAttributedTo

Attributes the assertion to an agent or authority.

$nanopublication:

$assertion level

The shared context defines no assertion predicates. Assertion predicates are domain-specific and usually come from a local overlay context.
