robos:ContextSource

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

Details

Class	robos:ContextSource
Shape id	urn:robos:shape:ContextSourceShape
Package	Core Platform (robos.platform) (core-platform)
Classification	Agents & MCP
Schema.org type	schema:DataFeed

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	Context Source must have a title.
robos:sourceType	1..*	xsd:string	Context Source must declare source type (file, folder, url, github, repo, ticket).
robos:location	1..*	-	Context Source must specify location path, URL, or repository identifier.

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.
