:: metadata-store [landscape]:
::
:: data store for application metadata and mappings
:: between groups and resources within applications
::
:: 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 path and path using (scot %t (spat path))
::
:: +watch paths:
:: /all associations + updates
:: /updates just updates
:: /app-name/%app-name specific app's associations + updates
::
:: +peek paths:
:: /associations all associations
:: /group-indices all group indices
:: /app-indices all app indices
:: /resource-indices all resource indices
:: /metadata/%path/%app-name/%path specific metadatum
:: /app-name/%app-name associations for app
:: /group/%path associations for group
