Bixby Developer Center

The viv.core capsule provides a set of foundational models for Bixby capsules. These include definitions for primitive concepts such as Integer, Boolean, and Text, as well as base concepts extended by other library capsules.

This reference lists out several of the models available in this library capsule. Some sections contain tables listing information about those concepts or actions.

Models

Types are always in the viv.core.* namespace. All properties have a cardinality of min (Optional), max (One) unless otherwise specified.

Primitives

• Boolean (boolean): The supertype of all primitive boolean concepts.
• Confirmation: (boolean): Concept used for matching confirmation prompts.
• Decimal (decimal): The supertype of all primitive decimal concepts.
• FormElement (name): Concept for wrapping references to be resolved by the client.
• Integer (integer): The supertype of all primitive integer concepts.
• Intent (text)
• MeasurementSystem (enum): One of Imperial, Metric, or USC.
• Text (text): The supertype of all primitive text, name, enum, and qualified concepts.
• Url (text)

These concepts can be used in your capsules as types for structure properties, as long as those properties are not referred to in Bixby Views or used as action inputs.

Shapes

These are structures used for shape metadata. They are used in geometry structures and BaseImage. The two shape structures are Base2dShape and BaseXyPoint.

Base2dShape

BaseXyPoint

BaseImage

A structure used for image metadata. This is used, among other places, by some Bixby Views components.

Date and Time

Use models from viv.time in your capsule to work with date and time values.

• BaseDate: Base for viv.time.Date. Properties of this viv.core.BaseDate structure have a default-value of 0.
• BaseDateInterval: Base for viv.time.DateInterval.
• BaseDateTime: Base for viv.time.DateTime.
• BaseDateTimeInterval: Base for viv.time.DateTimeInterval.
• BasePeriod: Base for viv.time.DurationPeriod. Properties of this viv.core.BasePeriod structure have a default-value of 0.
• BaseTime: Base for viv.time.Time.

Geometry

Use models from viv.geo in your capsule to work with geometry values.

• BaseDistance: Base for viv.geo.Distance.
• BaseDistanceUnit: Base for viv.geo.DistanceUnit.
• BaseGeoIcon: Base for viv.geo.GeoIcon.
• BaseGeoMarker: Base for viv.geo.GeoMarker.
• BaseGeometryWKT: Base for viv.geo.GeometryWKT.
• BaseGeoPoint: Base for viv.geo.GeoPoint.

Metadata

• Locale (structure): Stores information about a locale, as accessed through the getLocale() Expression Language function.

MultiModalString

The MultiModalString structure is the type returned by the macroEach EL function. It is a simple structure with two properties, text and speech, both of viv.core.Text type.
