:: metadata-store [landscape]:
::
:: data store for application metadata and mappings
:: between groups and resources within applications
::
:: group-paths are expected to be an existing group path
:: resources are expected to correspond to existing app paths
::
:: note: when scrying for metadata, to make the arguments safe in paths,
:: encode group-path and app-path using (scot %t (spat group-path))
::
:: +watch paths:
:: /all associations + updates
:: /updates just updates
:: /app-name/%app-name specific app's associations + updates

:: /resource-indices all resource indices
:: /metadata/%group-path/%app-name/%app-path specific metadatum
:: /app-name/%app-name associations for app
