The
...
"identify
...
sources
...
of
...
valued
...
information"
...
paragraph
...
is
...
not
...
clear.
...
For
...
example,
...
"the
...
services,
...
models,
...
and
...
annotations
...
provide
...
definitions
...
which
...
can

identify
...
candidate
...
sources
...
for
...
integration".
...
Integration
...
of
...
what
...
and
...
what
...
for?
...
RESOLUTION:
...
Candidate
...
sources
...
for
...
integration
...
are
...
services
...
that
...
can
...
be
...
linked
...
together
...
to
...
form
...
workflows.
...
The
...
semantics
...
derived
...
from
...
the
...
services
...
provide
...
a
...
framework
...
for
...
developing
...
automated/semi-automated
...
workflows.
...
The
...
SI
...
team
...
is
...
currently
...
working
...
to
...
prototype
...
to
...
assess
...
the
...
feasibility
...
of
...
this
...
automated
...
workflows
...
using
...
service
...
metadata.

Crucial
...
in
...
the
...
"common
...
representations
...
and
...
transformations"
...
paragraph
...
is
...
the
...
concept
...
of
...
"common
...
representation".
...
This
...
is
...
not
...
reflected
...
in
...
the
...
paragraph
...
itself
...
(where
...
consistency
...
is
...
mentioned).
...
A
...
common
...
representation
...
comes
...
before
...
anything
...
(this
...
or,
...
as
...
rightly
...
mentioned,
...
transformations
...
between
...
representations).
...
Consistency
...
is
...
secondary,
...
in
...
the
...
sense
...
that
...
if
...
an
...
appropriate
...
common
...
representation
...
is
...
chosen
...
(say
...
OWL-DL),
...
then
...
consistency
...
will
...
be
...
verifiable
...
by
...
reasoners.
...
RESOLUTION:
...
The
...
text
...
did
...
not
...
intentionally
...
leave
...
out
...
common
...
representation,
...
the
...
text
...
is
...
just
...
providing
...
additional
...
context,
...
as
...
common
...
representation
...
is
...
in
...
the
...
title.

The
...
sentence
...
"Because
...
of
...
the
...
complexity
...
of
...
the
...
reasoning
...
requirements,
...
the
...
OWL
...
2
...
specification
...
is
...
required
...
in
...
order
...
to
...
support
...
the
...
Semantic
...
Infrastructure
...
2.0"
...
is
...
highly
...
debatable.
...
First,
...
the
...
reasoning
...
requirements
...
would
...
not
...
lead
...
to
...
the
...
use
...
of
...
OWL
...
2
...
per
...
se.
...
The
...
expressiveness
...
needed
...
for
...
representing
...
semantic
...
metadata
...
might
...
call
...
for
...
OWL
...
2,
...
but
...
reasoning
...
requirements
...
would
...
boil
...
down
...
to
...
reasoning
...
tasks
...
such
...
as
...
subsumption
...
checking,
...
satisfiability
...
checking,
...
consistency
...
checking,
...
query
...
entailment,
...
etc,
...
for
...
which
...
the
...
complete
...
OWL
...
2
...
would
...
most
...
likely
...
be
...
impractical.
...
Indeed
...
general
...
reasoning
...
tasks
...
with
...
OWL
...
2
...
(the
...
DL
...
variant)
...
are
...
NEXP
...
or
...
higher
...
(nondeterministic
...
exponential,
...
which
...
is
...
worse
...
than
...
exponential).
...
It
...
seems
...
not
...
appropriate
...
to
...
mention
...
here
...
that
...
the
...
OWL
...
2
...
standard
...
will
...
be
...
required.
...
More
...
likely,
...
one
...
wants
...
to
...
resort
...
to
...
less
...
expressive
...
variants
...
of
...
full
...
OWL
...
2
...
(such
...
as
...
the
...
tractable
...
OWL
...
2
...
profiles)
...
to
...
ensure
...
scalability.
...
Tasks
...
like
...
composition
...
prove
...
to
...
be
...
intractable
...
when
...
the
...
language
...
of
...
the
...
background
...
ontologies
...
is
...
too
...
expressive
...
(which
...
includes
...
OWL
...
2).
...
RESOLUTION:
...
The
...
SI
...
team
...
will
...
be
...
validating
...
some
...
of
...
these
...
assumptions
...
and
...
this
...
section
...
will
...
be
...
updated
...
based
...
on
...
our
...
assessment.
...
Note
...
that
...
the
...
the
...
roadmap
...
is
...
baseline
...
that
...
is
...
being
...
validated
...
by
...
some
...
inception
...
activities
...
to
...
assess
...
the
...
feasibility
...
and
...
validity
...
of
...
some
...
of
...
the
...
assumptions.

Functions

November

version

The
...
decision
...
support
...
functions
...
are
...
on
...
a
...
very
...
specific
...
technical
...
level,
...
and,
...
given
...
this
...
granularity,
...
they
...
seem
...
incomplete.
...
For
...
example,
...
why
...
mention
...
"providing
...
scheduling
...
and
...
access
...
information
...
to
...
choreographer",
...
if
...
you
...
do
...
not
...
mention
...
how
...
choreography
...
itself
...
would
...
work
...
-
...
-
...
or
...
for
...
that
...
matter
...
how
...
it
...
is
...
defined?
...
RESOLUTION:
...
The
...
decision
...
support
...
functions
...
are
...
not
...
meant
...
to
...
be
...
a
...
final
...
list
...
of
...
all
...
functions,
...
they
...
provide
...
a
...
baseline
...
for
...
further
...
review
...
and
...
assessment.
...
Specifically
...
the
...
requirements
...
phase
...
of
...
the
...
project
...
will
...
determine
...
the
...
final
...
set
...
of
...
services
...
and
...
functions.
...
The
...
ones
...
currently
...
listed
...
in
...
the
...
roadmap
...
are
...
primarily
...
to
...
communicate
...
the
...
kinds
...
of
...
services/functions
...
that
...
are
...
required.
...
Please
...
feel
...
free
...
to
...
suggest
...
additional
...
services/functions
...
that
...
can
...
be
...
added
...
to
...
the
...
list.

The

function
...
"execute

reasoning
...
systems
...
against
...
gathered
...
data
...
providing
...
classification
...
and
...
additional

data"
...
is
...
meaningless:
...
what
...
is
...
additional

data?
...
Why
...
are
...
functions
...
that
...
would
...
actually
...
enable
...
the
...
service
...
discovery,
...
as
...
described
...
before,
...
not
...
mentioned?
...
RESOLUTION:

The

has

updated

to

make

it

more

and

understandable.
