Sections & Ordo

A Section is a major division of a service. An Ordo is the complete template for a service type.

{
  "id": "ordo-kidase",
  "type": "eucharist",
  "tradition": "eotc",
  "label": { "en": "Divine Liturgy / Kidase" },
  "sections": [{ "$ref": "sec-preparation" }, { "$ref": "sec-entrance-rites" }, { "$ref": "sec-liturgy-of-word" }],
  "properSlots": ["psalm-of-the-day", "gospel-of-the-day"]
}

Define Sections Separately

An Ordo references sections; each section then orders blocks or proper slots. This keeps a section reusable across service variants.

{
  "id": "sec-liturgy-of-word",
  "type": "section",
  "label": { "en": "Liturgy of the Word" },
  "blocks": [{ "$ref": "block-epistle" }, { "$ref": "block-gospel" }]
}

Use a block for a reusable sequence of closely related elements. Use a section for a major navigable division whose identity matters to service structure, proper mutations, or timeline reporting.

The sections array determines the ordinary order. Calendar resolution may alter that order only through explicit proper mutations.
