Models: the file formats
A model is a folder of diagrams that belong together: a main.archify at its top, any number of diagrams below it, and *.archify-registry files for the things several diagrams share. Three file kinds, all YAML, all read by the extension; Archify itself only ever sees plain diagrams.
main.archify
schema_version: 1
model:
id: online-shop
name: Online Shop
description: >
Web shop, its API, workers and stores.
Optionally, below the model block, a diagram exactly as in any other .archify file (diagram_type, meta, components, …). The extension shows it on the model page; Archify never sees the model block.
name.archify-registry
schema_version: 1
elements:
api:
type: backend
label: API
sublabel: REST service
brand: node-js
description: >
Node.js service behind the load balancer.
diagram: 0300-components/api.archify
db:
type: database
label: Database
sublabel: PostgreSQL
brand: postgresql
description: Orders, customers and catalogue.
- The key is the element's id, unique across all registry files of the model.
type,label,sublabel,tag,icon,brand,sourcesare Archify's component fields and are copied into every diagram that refers to the element.descriptionis the one description of the thing; shown on hover and on the model page, never sent to Archify.diagramis the link: the diagram that explains the element, relative to the model root. Clicking the element in any diagram opens it.
A diagram that refers to the registry
components:
- ref: api
pos: [250, 160]
size: [130, 60]
- ref: db
label: Orders DB # a diagram may override label, sublabel, tag
pos: [460, 260]
size: [130, 60]
- id: cron # an unshared element, inline, as today
type: backend
label: Nightly job
pos: [460, 420]
size: [130, 60]
refnames a registry element;iddefaults to the same name.id: db-replicawithref: dbdraws the same element twice or under another id.- A diagram may override
label,sublabelandtag; nevertypeorbrand(if those differ, it is a different element). - Before Archify runs, the extension replaces each
refcomponent with the registry element plus the diagram's own fields, dropsdescriptionanddiagram, and hands Archify an ordinary component. - Connections, boundaries and everything else stay as they are and use the ids as before.
Cards under a model diagram
Archify shows cards (a coloured dot, a title, a few lines) below a diagram. A diagram inside a model that draws shared elements and defines no cards of its own gets one card per drawn element that has a description in the registry, in drawing order, with the dot colour of the element's type. Write your own cards: in the diagram to replace them.
Links between diagrams
A diagram may point at another diagram from a component, whether shared or inline:
- ref: api
pos: [250, 160]
size: [130, 60]
diagram: 0300-components/api.archify # overrides the registry's link for this diagram
Registry diagram links and component diagram links are the same mechanism; the component's wins when both exist. Paths are relative to the model root.
Outside a model
A diagram with ref components outside any model (no main.archify above it) reports "no registry found" and shows the component by its ref name with type external, so the picture still renders.
Starting a model
Archify | New Model… (right-click a folder, File → New File…, Command Palette) offers three complete examples: C4 - Standard Web App, C4 - E-Shop and C4 - Event-Based Integration. Pick one and a folder name; the example is copied into that folder with model.id, model.name and the overview title taken from the folder name (an example kept under its own name is copied as is). Each example has registry/{people,systems,containers}.archify-registry and diagrams under 0100-context, 0200-containers and 0300-components; every registry element is used by at least one diagram and every diagram validates.
