The
...
...
...
...
is
...
a
...
consortium
...
that
...
develops
...
specifications
...
for
...
services
...
related
...
to
...
online
...
identity.
...
Internet2
...
has
...
contributed
...
by
...
invitation
...
to
...
a
...
number
...
of
...
their
...
specifications
...
dating
...
back
...
several
...
years.
...
Of
...
late,
...
these
...
specs
...
have
...
been
...
divided
...
into
...
three
...
broad
...
groupings:
...
- Liberty
...
- ID-FF:
...
- Identity
...
- Federation
...
- Framework
...
- Liberty
...
- ID-WSF:
...
- Identity
...
- Web
...
- Services
...
- Framework
...
- Liberty
...
- ID-SIS:
...
- Identity
...
- Services
...
- Interface
...
- Specifications
...
The
...
first
...
of
...
these,
...
Liberty
...
ID-FF
...
(through
...
version
...
1.2
...
),
...
was
...
a
...
forerunner
...
to
...
the
...
SAML
...
2.0
...
specification.
...
SAML
...
2.0
...
is
...
now
...
an
...
OASIS
...
standard
...
and
...
is
...
the
...
basis
...
of
...
the
...
next
...
major
...
version
...
of
...
Shibboleth.
...
All
...
of
...
the
...
functionality
...
in
...
ID-FF
...
has
...
been
...
incorporated,
...
usually
...
in
...
more
...
coherent
...
fashion,
...
into
...
SAML
...
2.0,
...
and
...
there
...
are
...
no
...
plans
...
by
...
the
...
Shibboleth
...
Project
...
to
...
support
...
any
...
of
...
the
...
historical
...
Liberty
...
ID-FF
...
specifications.
...
Consider
...
ID-FF
...
a
...
legacy
...
platform.
...
The Liberty ID-SIS
...
specifications
...
are
...
essentially
...
applications,
...
high-level
...
web
...
service
...
interfaces
...
that
...
support
...
particular
...
use
...
cases
...
like
...
data/profile,
...
geolocation,
...
contact
...
book,
...
and
...
presence
...
services.
...
These
...
may
...
be
...
of
...
interest
...
to
...
Shibboleth
...
deployers
...
in
...
the
...
future,
...
but
...
are
...
essentially
...
the
...
top
...
of
...
the
...
stack
...
and
...
may
...
be
...
useful
...
as
...
examples
...
of
...
what
...
ID-WSF
...
can
...
do
...
as
...
much
...
as
...
anything
...
else.
...
Liberty ID-WSF
...
is
...
the
...
focus
...
of
...
some
...
of
...
the
...
future
...
work
...
that
...
the
...
Shibboleth
...
development
...
community
...
might
...
engage
...
in.
...
<!-
...
- I
...
emphasize
...
might
...
.
...
-->
...
There
...
are
...
no
...
promises
...
other
...
than
...
to
...
say
...
that
...
as
...
a
...
standards-based
...
software
...
project,
...
it
...
makes
...
sense
...
to
...
evaluate
...
whether
...
these
...
specifications
...
provide
...
viable
...
solutions
...
to
...
some
...
of
...
the
...
use
...
cases
...
that
...
go
...
beyond
...
current
...
work.
...
We
...
suggest
...
interested
...
parties
...
with
...
their
...
own
...
extensions
...
and
...
adaptations
...
of
...
Shibboleth
...
or
...
related
...
code
...
seriously
...
evaluate
...
their
...
use
...
cases
...
against
...
these
...
specifications
...
before
...
pursuing
...
overlapping
...
proprietary
...
solutions.
