Qualifiers and References

NeoWiki Statements have no qualifiers, references, or rank, unlike Wikibase Statements. A Statement is flat: one property and its Value, with no inner structure. You express qualified and referenced data by reifying it — the value that needs context becomes its own Subject with its own Schema, linked from the main Subject by a Relation. A page can hold any number of Subjects (ADR 7), so this adds Subjects, not a page per value.

NeoWiki is a Property Graph: Subjects are nodes with typed properties and Relations are edges.

For the underlying concepts (Subject, Statement, Relation, Schema), see the Glossary.

Qualifying a value or a link: model it as its own Subject

Promoting a value into its own Subject is the same move as a Semantic MediaWiki subobject, except the intermediate node has a Schema.

Take a museum's yearly attendance. Define an Attendance Schema and link one Attendance Subject per year:

Museum Schema
  Attendance figures: relation → Attendance (multiple)

Attendance Schema (Subjects are dependent)
  Year:     number
  Visitors: number
  Source:   url

Each Attendance Subject ({ Year: 2024, Visitors: 2500000, Source: "https://…" }) holds what Wikibase would put as a qualifier (Year) and a reference (Source) on one visitor-count Statement. Here they are typed properties governed by the Attendance Schema, so they validate and render like any other data. A linked Subject can link to further Subjects, with no depth limit. Qualify a link the same way: retarget the Relation at a new Subject that holds the qualifying properties and carries its own Relation to the original target.

The Attendance Schema declares its Subjects dependent: each Attendance Subject is edited in the museum's editor, stored on the museum's page and removed with the museum.

References

A reference is provenance, modelled as an ordinary property: add a Source (or similar) property to the linked Subject's Schema.

Rank

NeoWiki has no rank. What rank encodes is ordinary data: model it explicitly — typically a date property for current vs. historical values, or a status property for deprecated ones.

Mapping from Wikibase

Wikibase	NeoWiki
Statement	A Subject's Statement (property + value), or a Relation
Qualifier	A property on a linked Subject (reify the value or the link)
Reference	An ordinary property (e.g. Source) on the linked Subject
Rank	No equivalent; model explicitly (dated Subjects, status properties)
Statement ID	Statements have none; Subjects and Relations both have stable IDs
novalue / somevalue	No equivalent

In RDF

A qualified value round-trips without loss: a linked Subject is its own resource, and a Relation keeps its ID (Graph Model). See RDF Export for the native projection and Mapping Format for projecting into standard ontologies such as EDM.

Presentation

How a property renders is set by Display Attributes and Layouts, not by fields on the Statement.
