- Chair: Amy
Chair to start the meeting by typing on irc:
trackbot, start meeting
Trackbot should already be on the channel but if for some reason it is not call it with the following command:
Zakim won't know what meeting it is. Just ignore it. Pick a scribe from the list or ask Zakim to pick one up with the following command:
Zakim, pick a victim
Unfortunately Zakim has no idea who's scribed before so you may have to ask several times before getting an acceptable answer...
Also, with WebEx, Zakim doesn't know who is on the call so, as people join they should record their attendance with the command: present+ <nickname>
For additional info, see the Zakim documentation page.

LDN and AP alignment
cwebber read LDN stuff .. has questions
if translating between Activity Pub and LDN, then all seems fine
with JSON-LD and Activity Streams .. should be pretty easy
1. what do we think re: inbox .. could we share that between the two of them?
even though they don't apply to LDN?
rhiaro: we have small stumbling block with W3C namespace policy .. working on
... 1. we could get this added to LDP .. you could alias your inbox to ours
... 90% sure that should be OK
... 2. OR .. (early to think about) .. IF W3C namespace policy gets updated to allow <something> .. then maybe Activity Pub terms could be added to AS2 namespace
cwebber: yes, that'd simplify a lot of things for us
rhiaro: Sandro -- how likely is this to happen?
... we don't need a hardcore resolution quite yet .. maybe by end of Sept
sandro: not sure I can say anything now
... assuming someone could amend the policy .. then, does anyone have any issues with using the AS2 namespace
rhiaro: in any case we could use alias for LDP
... therefore they will converge
cwebber: I forgot to mention .. the way the inbox is discovered is diff
... I'd be fine in my implementation to support both ways ...
(maybe cwebber can document the 2 ways)
rhiaro: actually, LDN says there are 2 ways to discover inbox .. if 1st way fails, then you have to do the 2nd way
cwebber: I thought it did specify order
rhiaro: yes, we changed that in updated version
<csarven> "These may be carried out in either order, but if the first fails to result in an Inbox the second MUST be tried."
cwebber: oh, ok
rhiaro: I guess we need to make that clearer
csarven: is there an issue where the receiver announces a header, but it's only found in body? (not sure I got that correctly)
rhiaro: <explains yes, and how it workds>
cwebber: makes sense
... you specify a 201 be returned to confirm, we should add that to AP
rhiaro: yes, although what's in the notification, is a black box
... LDN lets you send just whatever is relevant to what you're doing
... I've written, but not typed up, how I see this working
... what I'm trying to do, is make it easy enough that AP could use the LDN stuff to do XYZ
cwebber: that is, strip down ASub and use LDN for those processes?
cwebber: hmm, I need to talk with tsyesika and evan .. to make sure there aren't unexpected glitches
rhiaro: of course
cwebber: let's sketch this out next week, when you come visit ... interesting idea; I hadn't thought about it
... let's sketch it out together, and then take it to evan and tsyesika to see if it's feasible
rhiaro: this is part of the idea re: modularization
... AP doesn't have to do <XYZ>..
cwebber: a potential sticky issue, but probly not a blocker...
... modularizing these functions, might fracture <something>
... want to keep it "clean"
rhiaro: yes, I agree
... part of what Social Web Protocols will do is sketch out how the whole system will look
... and one can pick and chooset the pieces
cwebber: cool; I certainly think it's interesting. Not totally sold, but I'm close
rhiaro: great; it'll probably help if I write up my other notes
cwebber: that's it for me; for what I'd written down... anything else to discuss
cwebber: do you get the whole container all at once, or do you get a stream?
rhiaro: trying to find the balance on how to specify that ... I think we have an issue on that
<someone> : does AP address that?
cwebber: uses AS2 version of things, but I guess that's an omission in our spec
rhiaro: Web annotations protocol, uses AS paging
... in order to plug into annotations directly
<melvster> seeAlso: "A new HTTP response code say 209" https://lists.w3.org/Archives/Public/www-tag/2013Dec/0041.html
rhiaro: all the points of alignment are listed in Issue 36
<melvster> "You asked for a large thing, this is the first page of it. See Proposal "
rhiaro: be sure to add or discuss
... I think we've covered the main stuff
rhiaro: next week I'm taking a small trip to visit cwebber, where we can hack on stuff and see if it actually works
csarven: are we OK with the MIME type?
<discussion about options>
cwebber: need to talk with evan and tsyesika, but doesn't seem like a big deal
<csarven> ATM: https://www.w3.org/TR/ldn/#sending-activitystreams2-support
cwebber: how about if we both file an issue on that, but make the point that we both agreed on this call!
rhiaro: great! anythign else?
... let's get to work then
cwebber: great call! see you next week, Amy
trackbot, end meeting
