Goals

The goal of this meeting is to continue the work done at the last meetup, where we will continue the work to design a format for communicating activities performed by users across different sites, and begin to spec out an interoperable protocol for sharing activities between Drupal and WordPress sites.

Notes

Scope of the effort... 

  • drupal - wordpress - MT --> build by Dec 12
  • interop between agreggators
  • reusing xrds-simple types for verbs
  • a spec that could be used for opensocial

Based on ATOM

Make use Media Types/MIME

CRUD for verbs?

 

User-agent problem? (i.e. matching on arbitrary strings)

 

Activity Types vs templates

 

facebook sizes... small, medium, large

 

multiple direct/indirect objects

 

deduping -- "somebody tweeted this", as well as complete object

 

dugan: 1 or more actors... 0/1 direct object, 0/1 indirect object

 

merging same activities across different actors: "chris, job and bob downloaded Transformers, The Matrix and Wedding Planner."

 

privacy issues with merging activities

 

err on the side of atomic activities

 

separate aggregation from data streams that people are using and resharing

 

data-duplication...

 

attending events... 

 

activity streams attached to both actors and to objects

 

templates... would encode verbs/location

 

separate model from view

 

actor --> points to profile

direct object --> point back to originating service

permalink to for activities?

 

call to action... "add your [service name ID]" -- mybloglog

 

geolocation

 

best practices -- use microformats

 

expiry, synchronization? 

 

story sizes... versioning...?

 

revoking an activity?

 

XRDS-Simple types for small medium large -- just different types rather than different sizes of the activity...

 

music, video, blog posts, tweets, 

 

URL template for different representations of an object...

 

each type specifies the different sizes

 

action/activity streams for DiSo

 

subscribing to external type templates

 

dugan presented activity streams rails plugin to rails meetup...

 

merging objects/activities...

 

link-ref; in-reference-to in ATOM... "rel=ref"

 

an aggregated lifestream feed could be out of scope... 

 

close to real-time web...

 

fetching passed events...??

 

...pass on the GUID?

 

recommendation that people should follow ATOM spec... and that activities must have GUIDs... 

 

there is a type that aggregators can offer like "merged-type"...

Media

Audio recording of the event.
