+
+SO Sub-Components
+------------------
+
+**API Handler**
+
+ RESTful interface to northbound clients
+
+ * Handle service-level and infrastructure (VNF & network) requests
+
+ Service-agnostic APIs
+ * “Service Instantiation API”
+
+ Model-driven recipe selection
+ * Use SO Catalog to map input requests to BPMN flows
+ * Dynamic lookup based on service-model + action
+ * Input data forwarded to BPMN flow
+
+ Track open and completed requests via SO Request DB
+
+ Multiple API-H modules may support different APIs
+
+**BPMN Execution Engine**
+
+ Open-source Camunda platform
+ * Support BPMN 2.0 service recipes
+
+ Expose RESTful interface to API-H (unique path per recipe)
+
+ Make use of common “building block” sub-flows
+
+ Sequence orchestration steps for each Resource in the recipe
+ * Request and configure network resources via SDN-C
+ * Manage cloud resources via PO (OpenStack)
+ * Update inventory via A&AI
+
+ Perform error handling/rollback
+
+**Resource Adapters**
+
+ Interfaces to lower level controllers and other ONAP components
+ * Platform Orchestrator, SDN-Controller, APP-Controller, VFC-Controllers
+ * Hides the details of complex interfaces (e.g. OpenStack APIs)
+ * Expose interfaces to BPMN flows as SOAP or REST APIs
+ * Support synchronous and asynchronous operations
+
+ Provided as part of SO platform for use by all BPMN flows
+
+ Use SO Catalog to map resource requests to a recipe/template
+
+ Data-driven design
+ * Catalog templates may be updated via self-service (outside of release cycles)
+ * Merge input parameters with templates at run-time
+
+**Data Stores**
+
+ Request DB
+ * Tracks open and completed requests
+
+ SO Catalog
+ * SO view of the SDC Catalog
+ * service and resource models, recipes, and templates
+ * Populated via SDC distribution service from TOSCA models
+
+ Camunda DB
+ * Maintain state for BPMN flows
+ * Supports multiple active engines
+
+**SDC Distribution Client**
+
+ Receive updated service models from SDC
+ * Event-bus notifications when new models available
+ * HTTP retrieval of models (TOSCA) and artifacts (Heat)
+
+ Receive distributions as TOSCA models
+
+ Populate SO Catalog
+
+ Support self-service updates to models and artifacts
+
+Third Party and Open Source
+---------------------------
+
+**BPMN Engine**
+ Camunda (open source)
+
+**Other Open Source Components of Note:**
+ JBOSS EAP/Wildfly
+ MySQL/MariaDB
+ Openstack Java SDK (“woorea”)
+
