osapi.people.get({userId: '@owner', groupId:
'@friends'}).execute(function(result) {
if (!result.error) {
alert('You have ' + result.totalResults + ' friends');
}
});

Specific
Fields
(“Proper@es”)
osapi.people.getViewer({fields: ['displayName',
'birthday']}).execute(function(result) {

alert('Your birthday is ' + result.birthday + '!');

12. A
General
Ques@on
Given
that
we
have
a
number
of
vendors
that
are
acAvely
working
on
products
and
soluAons
that
use
both
OpenSocial
and
CMIS…
and
similar
concepts
appear
in
each
spec…
…as
OpenSocial
and
CMIS
emerge
in
the
enterprise,
can
we
provide
a
consistent,
open,
standards
based
programming
model
to
our
customers
that
leverages
the
strengths
of
each
specificaAon,
promotes
interoperability,
and
fosters
sharing
and
collaboraAon
between
communiAes?

13. More
ques@ons,
some
ideas,
some
first
steps…
• Are
there
“low
hanging
fruit”
that
we
can
do
to
“test
the
waters”?
– Build
CMIS
gadgets
to
demonstrate
parts
of
Chemistry
– Build
gadgets
to
show
how
the
APIs
can
work
together
– Add
OpenSocial
MediaItems
as
a
CMIS
Document
subclass
– Create
a
CMIS
based
extension
for
exis@ng
OS
MediaItems
Some First Steps…
(will be done in open source – not sure which project)
• MediaItems & Albums seem to overlap with CMIS
• Created a bi-directional mapping utility
Next Steps…
• In process of integrating mapping utility as binding with
Shindig
• Demonstrate complimentary APIs via OpenSocial Gadget
• Retrieve document info (CMIS) & Person info (OS)
• Create document (CMIS) & Post Activity (OS)

14. More
ques@ons,
some
ini@al
ideas,
some
first
steps…
• Moving
forward,
what
makes
sense?
– What
changes
are
necessary
to
OpenSocial
to
bejer
support
CMIS?
• Add
new
“CMIS-­‐style”
MediaItems
(or
extensions)
• Formalize
rela@onships
– Create
CMIS
“bindings”
for
OpenSocial
JavaScript?
• Leverage
simple
OS
API
programming
model,
Templates,
Features
• Adds
social
constructs
“for
free”
– OAuth
support
in
Chemistry?
