Inside a Virtual Acoustic Object
One semantic release. Multiple ways to carry and access its resources.
VAO 0.5.0 separates the semantic release from its physical carriers. The manifest describes resources and their relationships. A carrier packages exact realizations of those resources for transport. Changing the delivery arrangement does not, by itself, create a different semantic release.
Three carrier roles
| Carrier | Purpose |
|---|---|
| Bootstrap | A small entry point for discovery and evidence, with references to further resources. |
| Preservation closure | Contains every realization required by the complete release. |
| Custom | A locally materialized selection for a particular task or byte budget. |
