# PubSub Access Model (Open?)
Minutes: https://pad.riseup.net/p/4low3EzWFot77PEExefx
## Currently the access model is underspecified/not set to "open".
## Open would be a better candidate for the default access model as access to the public key is necessary for encryption
## Important to check signatures
## Should we only upload minimal key to open pubsub node, and more verbose key to contacts-only node?
# Key Reuse?
## Should we allow import of external key?
## We can (and should) probably have guidelines for client behavior in case the node is restricted (vs non existend)
## "External Key" -> Inclusion of all userids would leak identity
## Profanity allows to upload filtered key (user choses what to upload)
# Define "Profile" for OX (declare algorithms, key formats...)?
## What parts of the key to upload? Signatures, UserIDs, minimal key?
## One key per recipient? -> YES please. For other use cases -> subkeys
# How to identify own key on your local device? -> If there are multiple, ask the user once and store the key id.
# How to identify which subkey to encrypt to -> It is not specified anywhere (not in rfc4880) which encryption subkeys to encrypt to if there are multiple options.
# Notification Traffic Optimization
## Did we get it right? -> possibly maybe
## Notifications when a key from a remote party is updated
## Public Key Metadata Node needs to use Item-IDs (right now it does not?)
## Consider Payload-less notifications for metadata updates
# EMail-Gateway: (Sorry, I missed the point :D) Multiple keys would make email gateways hard? -> use one key per account please
# Come up with an easy device-onboarding guide on modernxmpp or somewhere. -> also link to it from the XEP
# Adoption of SCE -> Not much to gain here, but if we make a breaking change we should switch to SCE.
