00:49:57	Oleg Silkin:	Is there a link to the autocodec proposal?
00:50:24	Brooklyn Zelenka (@expede):	Not formal, but here's some slides https://noti.st/expede/CWHgTE/ipld-autocodec
00:50:36	Oleg Silkin:	Thanks Brooklyn!
00:51:57	Brooklyn Zelenka (@expede):	Also Oleg — here's the high level IPVM proposal that I gave, but is not "the" canonical IPVM https://noti.st/expede/oq0ULd/ipvm-interplanetary-vm
00:52:41	Oleg Silkin:	Thanks Brooklyn! I read through it last week, it's very cool!
00:52:47	Brooklyn Zelenka (@expede):	Thanks!
00:59:57	Oleg Silkin:	I have to drop off, thanks all!

Excited to see the recording! Sadly couldn't make it to the call due to other obligations. 😁

Attendees:

• Brooklyn Zelenka - CTO at Fission, Working Group Lead
• Adin Schmahmann - Kubo maintainer
• Jonathan Essex - Engineer at Fission
• Oleg Silkin - Associate Software Engineer at RedHat. Decentralized storage.
• Hannah Howard - Filecoin/Go-IPFS
• Melanie Riise - FVM Team. Community working group Web Assembly
• James Walker - Engineering Management at Fission

[Introductions]

Process: https://github.com/ipvm-wg is the place for long-term discussion

Brooke: (Interests/Contraints/Carry-Over from Rekjavik):

• Object Capabilities (OCAP)
• Agoric [ https://github.com/Agoric ]
• Spritely [ https://spritelyproject.org/ ]
• Distributed Message Bus / Differential Data Flow - intersection with Fission work
• Function Addressed Network Calls - PLN prior art [ Can’t find reference ]

Adin:
Lots of things we might want from WASM in IPLD. Universal CODECs and ADLs. Issues with WASM ABIs for other language.
There’s more needed on the IPLD side - way of signaling ADLS.

Hannah:
How is IPLD represented in WASM?

Adin:
current state for codec: https://github.com/ipld/ipld/pull/226/files
Won’t work for ADLs - too big. Need partial representation of structure.

Hannah:
issues such as integer sizes likely to be influenced by WASM

[ Some generalized hating on floats - issues due to nondeterministic/platform dependent behaviors ]

[ Discussion focused on ADL use case ]

Melanie:
Suggest re-use C apis

Jonathan:
Re-use prior art from XML processing stacks

Adin:
IPFS methods have rich implicit behaviors triggered by the signal - ‘IPFS://’.

[ Discussion surrounding autocodecs: https://noti.st/expede/CWHgTE/ipld-autocodec ]

[ Brooke would like feedback! ]

[ Discussion of signaling issues related to autocodes/ADLs ]

Jonathan:
Declarative versus Imperative signals, expressing intent of block producer vs requirement of block consumer

Melanie:
How to signal - undeveloped part of IPLD

Jonathan:
Single type signal at root of graph implies static typing; absent signal implies duck typing; to mix the two we need in-band signaling

Adin:
Look at the Version 2 CID spec: ipfs/specs#305

Hannah:
what’s this for, how do we get to something deliverable

Brooke:
get to working code ASAP, but there are many use cases. Topics that came out of Rekjavik:

• IPLD Calling Convention
• WASM specific IDL
• Execution bounding
• IPLI loading
• Hypervisor
• IPLD-Based Linking

Hannah:
What do you mean by Calling Via IPLD

Brooke:
Composing WASM modules + Invocation Spec

Adin:
Useful context: https://github.com/ipld/ipld/tree/master/notebook/exploration-reports

@expede or @softwareplumber : Awesome to see this happening. For giving community visibility to it, could meeting invites be sent to [email protected] ? This will cause it to appear on the IPFS Community Calendar.

Context: ipfs/ipfs-docs#1237

[BigLep]

There is discussion about a different want to give visibility to the IPFS community rather than a google calendar happening here: https://discuss.ipfs.tech/t/community-calendar-options-other-than-google-cal/14954 . In the meantime, I have added these events to the existing IPFS Community google calendar by personally joining the Luma events and inviting the IPFS community calendar. No further action needed at the moment.
