## Use it in a design

```yaml
nodes:
  - { id: "virtuoso", component: "virtuoso" }
```

## Source (`component` YAML, verbatim)

```yaml
# yaml-language-server: $schema=../../schema/component.schema.json
# OpenLink Virtuoso: hybrid RDBMS and RDF quad store on disk. Per "Cluster Installation and
# Configuration" sharding across self-contained partitions is the Elastic Cluster mode
# enabled through cluster.ini and needs at least two nodes; a plain install is single-server.
