Candidate subjects, predicates, and values used with delini_review to demonstrate controlled and open review ranges in Betwixt.
Format
A tibble with 13 rows and 6 columns:
- type
Component of an elementary semantic assertion to which the range entry applies:
subject,predicate, orvalue.- field
Optional predicate field to which a value range applies.
NA_character_indicates that the range is not restricted to a particular wide-review field.- rank
Display order of the candidate within its applicable range.
- label
Human-readable candidate value.
- namespace
Vocabulary namespace, where a controlled vocabulary term is supplied.
- url
External definition or vocabulary URL, where available.
Details
The table includes alternative interpretations of the review subject,
candidate predicates, selected vocabulary-backed values, and the reserved
other value used to permit an open proposal.
Range entries are identified by the component of an elementary assertion
to which they apply. Value ranges may additionally identify a field,
allowing a wide review to associate a range with a particular predicate
column.
Subject and predicate ranges are general components of an elementary
assertion and therefore do not require a field. The example value range
is associated with instance_of, allowing it to be used as the controlled
range for that predicate column in a wide review.
The dataset intentionally contains both vocabulary-backed and local candidate values. Missing namespaces or URLs therefore do not indicate missing data requiring correction.
The value other is reserved for an open-range review control that allows
the curator to propose a value not otherwise listed.
When a current assertion value also occurs in its applicable range, Betwixt may exclude that entry from the alternatives because the current value is rendered separately as the initially selected value.
