robos:DatabaseColumn

Validation shape for robos:DatabaseColumn nodes in the core-platform package group.

Details

Class	robos:DatabaseColumn

Package	Core Platform (robos.platform) (core-platform)
Classification	Data stores & messaging
Schema.org type	schema:Property
Domain standard	www.iso.org

Properties

Count is the minimum and maximum number of values (* means no maximum). The validator enforces both. The type column is documentation only; the validator does not check types.

Property	Count	Type	Rule or description
dcterms:title	1..*	xsd:string	Database Column must have a title.
robos:columnName	1..*	xsd:string	Database Column must specify column name.
robos:dataType	1..*	xsd:string	Database Column must declare data type.
robos:table	1..*	URI (robos:DatabaseTable)	Database Column must link to parent table.

Example node

The checked-in graph has no node of this class that passes the validator, so this is a placeholder built from the shape. It has every required property, with example values. It is not a node from the graph.

Validate the example

Save the example as node.json in the repository root, then run:

node -e "const { SHACLValidator } = require('./packages/robos-graph/lib/shacl-validator'); console.log(new SHACLValidator().validate([require('./node.json')]).conforms)"

The command prints true when the node meets every rule for its types.
