version

It
...
says
...
that
...
the
...
query
...
capability
...
must
...
support
...
sophisticated
...
queries
...
such
...
as
...
temporal
...
queries
...
and
...
spatial
...
queries.
...
In

that

case,

decision

support

earlier
...
should
...
mention
...
support
...
for
...
temporal
...
and
...
spatial
...
reasoning.
...
Resolution:
...
This
...
requirement
...
is
...
from
...
the
...
platform
...
roadmap;
...
the
...
platform
...
services
...
provide
...
access
...
to
...
data
...
while
...
the
...
SI
...
service
...
provide
...
access
...
to
...
metadata.
...
The
...
SI
...
team
...
is
...
evaluating
...
the
...
requirement
...
for
...
this

capability

and

will

update

the

with

its

November

version
...
The
...
terms
...
orchestration,
...
choreography,
...
and
...
composition
...
seem
...
to
...
be
...
used
...
interchangeably.
...
The
...
dynamic
...
composibility
...
of
...
services,
...
including
...
runtime
...
contract
...
discovery,
...
is
...
a
...
hard
...
if
...
not
...
unsolvable
...
task.
...
The
...
paragraph
...
would
...
benefit
...
from
...
a
...
more
...
careful
...
wording,
...
e.g.,
...
emphasizing
...
design-time
...
or
...
semi-automatic
...
composition,
...
where
...
specific
...
services
...
are
...
discovered
...
and
...
composed
...
to
...
solve
...
specific
...
tasks.
...
Note
...
that
...
in
...
a
...
composition
...
of
...
services,
...
current
...
state
...
of
...
the
...
art
...
abstracts
...
services
...
as
...
one
...
input/
...
one
...
output
...
only.
...
Additionally
...
taking
...
into
...
account
...
more
...
complicated
...
choreographies
...
of
...
2
...
services
...
interacting
...
is
...
not
...
feasible.
...
Resolution:
...
The
...
SI
...
team
...
is
...
currently
...
evaluating
...
different
...
approaches
...
to
...
identify
...
the
...
feasibility
...
of
...
automatic
...
workflow
...
composition.
...
Based
...
on
...
the
...
results
...
of

the

prototyping

phase,
...
the

roadmap

will

be

updated.

This

Functions

November

version
...
The
...
discovery
...
functions
...
are
...
rather
...
implementation-level
...
(involving
...
service
...
endpoints
...
and
...
service
...
interfaces).
...
What
...
about
...
the
...
discovery
...
of
...
services
...
based
...
on
...
a
...
declaratively
...
specified
...
goal
...
or
...
task
...
and
...
the
...
rich
...
metadata
...
of
...
services
...
using
...
semantic
...
reasoning?
...
Resolution:
...
This
...
section
...
lists
...
some
...
high-level
...
requirements
...
derived
...
from
...
the
...
requirements
...
section
...
of
...
the
...
SI
...
roadmap.
...
Service
...
discovery
...
is
...
expected
...
to
...
leverage
...
semantic
...
reasoning,
...
the
...
SI
...
team
...
is
...
doing
...
some
...
prototyping
...
to
...
identify
...
how
...
semantic
...
reasoning
...
can
...
be
...
leveraged
...
for
...
service
...
discovery.
...
This
...
section
...
will
...
be
...
updated
...
based
...
on
...
the
...
findings
...
of

that

exercise.
