Its a network of flows
Pub/Sub and Fat-ping (update)
Pub is flow out, Sub is flow in
SUB – Input any feed (RSS etc) converts to “data objects”
Internal database holds a redundant copy of all the “data objects” text/meta-data of all its SUBS
PUB – Output any feed (RSS, activity-pub etc.) a stream of “data objects”
The Fat ping are used to sync the tag based meta data for each “data object “across the sub/pub feeds.
All the non text data is held on the original server.
