Tutorial: Trait collection

This tutorial focuses on the same logical fact expressed three different ways: by a value-property alias, by an explicit traitId, and by a category-driven fallback.

By alias (pen)

{
  "traitCategory": "2.23.133.19.2.1",
  "traitRegistry": "2.23.133.18.3.3",
  "pen": "32473"
}

By traitId

{
  "traitId": "2.23.133.2.17",
  "traitCategory": "2.23.133.19.2.1",
  "traitRegistry": "2.23.133.18.3.3",
  "traitValue": {
    "oid": "1.3.6.1.4.1.32473"
  }
}

By traitCategory

{
  "traitCategory": "2.23.133.19.2.14",
  "traitRegistry": "2.23.133.18.3.3",
  "bool": "true"
}

Representative ASN.1

Trait ::= SEQUENCE {
  traitId         OBJECT IDENTIFIER OPTIONAL,
  traitCategory   OBJECT IDENTIFIER OPTIONAL,
  traitRegistry   OBJECT IDENTIFIER OPTIONAL,
  traitValue      ANY DEFINED BY traitId OPTIONAL,
  ...
}

1. By ID
2. By alias
3. By category
