Let's also keep in mind distinction between *vocabularies* and normative
*JSON-LD context*. We need to figure out if we need to freeze this
context or we can extend it after publishing the spec. This JSON-LD
context will allow people to work with simple strings using compacted
form and don't get into which vocabulary(ies) they map in expanded form
to full URIs.

At the same time, people who want to use extensions may need to
understand expended form. Or we could look for a way where IG can guide
design of extension JSON-LD context which will allow people using them
to stay in blissful compacted form using something like:

{
  "@context": [
    "http://www.w3.org/ns/activitystreams",
    "https://w3id.org/marketplace/v1"
  ]
 ...
}

[...]

I will live to ISSUE-15 discussion about ActivityStreams not focusing on
*Activities* but trying to innovate with Object, Collection (+ paging)
etc. While we still
* don't provide much clarity on activity vs. *result* of activity IMO
relevant to 'Connect as Verb or Connection as Object?' thread
* don't specify clearly past/present/future ( elf plans to attend next
Social WG F2F, elf currently attends Social WG F2F, elf attended Social
WG F2F) Please also see Amy's personal website  http://rhiaro.co.uk/
(Todo, Doing, Done)

Once again, I see much more urgent issues to resolve in WG than dealing
with particular types of possible Activities or Things/Objects.

I would like to once again emphasis *URI* recommendation in IG charter
http://www.w3.org/2013/socialweb/social-ig-charter.html#id-other-deliverables

"Social Vocabularies: Various standards such as ActivityStreams and RDF
allow various items of shared interest, such as products and actions
("likes"), to be named with a URI for reasons of interoperability.
Vocabularies are sets of these related URIs around particular activities
(business processes, sharing, shopping). The Interest Group may maintain
a list of shared URIs relevant for the use of social standards."

BTW I does NOT say anything about dereferencing those URIs ;)

Cheers!
