About this skill

Workflow Model Design (Cloud Service)

Design workflow models for AEM Cloud Service: step structure, transitions, OR/AND splits, variables, and model XML deployment.

Variant Scope

  • This skill is AEM Cloud Service only.
  • Models are stored at /conf/global/settings/workflow/models/. Do not write to /libs or /etc.

Workflow

Model Design Progress
- [ ] 1) Clarify the workflow purpose: what triggers it, what steps are needed, who approves
- [ ] 2) Map out steps: PROCESS (auto), PARTICIPANT (human), OR_SPLIT (decision), AND_SPLIT (parallel)
- [ ] 3) Decide payload type: single JCR_PATH page/asset, or multi-page via workflow package
- [ ] 4) Identify workflow variables needed for inter-step data passing
- [ ] 5) Design model XML: nodes + transitions + metaData with correct step properties
- [ ] 6) Add filter.xml entry with mode="merge" for the model path
- [ ] 7) Verify model synced to /var/workflow/models/ after deployment

Node Types Quick Reference

Type Purpose Key metaData property
START Entry point —
END Terminal —
PROCESS Auto-executed Java step PROCESS = FQCN or process.label
PARTICIPANT Human task (static assignee) PARTICIPANT = principal name
DYNAMIC_PARTICIPANT Human task (runtime assignee) DYNAMIC_PARTICIPANT = chooser.label
OR_SPLIT One branch selected by rule Transition rule = ECMA/Groovy
AND_SPLIT All branches execute in parallel —
AND_JOIN Wait for all parallel branches —
EXTERNAL_PROCESS Poll an external system EXTERNAL_PROCESS = FQCN

Cloud Service Deployment

  1. Place model XML at: /conf/global/settings/workflow/models/<name>/jcr:content/model/
  2. Add to ui.content package with filter.xml entry mode="merge"
  3. After Cloud Manager pipeline install: open Workflow Model Editor → Sync (or use deployModel())
  4. Engine reads from /var/workflow/models/<name> — verify sync succeeded
