JLD003 - Namespace Pollution¶

Severity: Warning Layer: JSON-LD Semantic

Description¶

Custom terms are used without proper namespacing. Terms should use a prefix (e.g., ex:customField) or be explicitly defined in the context to avoid collisions with standard vocabulary terms.

Example¶

{
  "@context": [
    "https://www.w3.org/ns/credentials/v2",
    "https://test.uncefact.org/vocabulary/untp/dpp/0.6.1/",
    {
      "myField": "https://example.com/vocab#myField"
    }
  ],
  "type": ["DigitalProductPassport"],
  "myField": "value",
  "anotherUnprefixedTerm": "problematic"
}

Warning: Term anotherUnprefixedTerm lacks proper namespacing.

Resolution¶

Use prefixed terms or define all custom terms in the context:

{
  "@context": [
    "https://www.w3.org/ns/credentials/v2",
    "https://test.uncefact.org/vocabulary/untp/dpp/0.6.1/",
    {
      "ex": "https://example.com/vocab#",
      "myField": "ex:myField"
    }
  ],
  "type": ["DigitalProductPassport"],
  "myField": "value",
  "ex:anotherTerm": "properly prefixed"
}
