Overview

...

In
...
an
...
effort
...
similar
...
to
...
developing
...
this
...
roadmap
...
for
...
Semantic
...
Infrastructure
...
2,0,
...
a
...
team
...
is
...
developing
...
a
...
roadmap
...
for
...
the
...
future
...
platform,
...
security
...
and
...
tools,
...
caGrid
...
2.0.
...
The
...
Semantic
...
Infrastructure
...
2.0
...
will
...
be
...
tightly
...
integrated
...
with
...
the
...
runtime
...
caGrid
...
2.0.
...
The
...
purpose
...
is
...
to
...
achieve
...
a
...
more
...
comprehensive
...
approach
...
to
...
computable
...
semantic
...
interoperability
...
then
...
is
...
possible
...
with
...
the
...
existing
...
integration
...
between
...
caDSR
...
and
...
caGrid
...
1.x.
...
With
...
the
...
adoption
...
of
...
SAIF
...
(Service-Aware
...
Interoperability
...
Framework)
...
and
...
Enterprise
...
Conformance
...
and
...
Compliance
...
Framework
...
(ECCF)
...
and
...
the
...
introduction
...
of
...
behavioral
...
semantics,
...
the
...
infrastructure
...
of
...
the
...
grid
...
must
...
provide
...
increasingly
...
sophisticated
...
support
...
to
...
leverage
...
and
...
enforce
...
behavioral
...
specifications.
...
The
...
notion
...
of
...
"computable
...
semantic
...
interoperability"
...
(CSI)
...
applies
...
semantics
...
to
...
not
...
only
...
the
...
static
...
data
...
passed
...
between
...
machines,
...
but
...
also
...
to
...
the
...
behavioral
...
and
...
functional
...
operations
...
exposed
...
for
...
coordination
...
of
...
behaviors
...
during
...
the
...
interaction.
...
Likewise,
...
the
...
semantic
...
infrastructure
...
itself
...
(that
...
is,
...
its
...
tools
...
and
...
applications)
...
are
...
being
...
transformed
...
to
...
fully
...
participate
...
in
...
the
...
new
...
services-aware
...
environment.
...
Thus
...
the
...
Semantic
...
Infrastructure
...
will
...
depend
...
on
...
the
...
grid
...
platform
...
as
...
at
...
least
...
one
...
of
...
potentially
...
many
...
delivery
...
platforms
...
for
...
its
...
information.
...
The
...
Semantic
...
Infrastructure
...
2.0
...
is
...
expected
...
to
...
provide
...
management
...
services
...
and
...
tooling
...
comparable
...
to
...
those
...
which
...
exist
...
today
...
(including
...
vocabulary
...
services,
...
model
...
management
...
and
...
annotation,
...
and
...
curation
...
tools
...
and
...
others
...
as
...
needed),
...
albeit
...
in
...
potentially
...
new
...
formats
...
and
...
standards.
...
However,
...
it
...
also
...
has
...
the
...
increased
...
scope
...
of
...
greater
...
flexibility
...
in
...
accommodating
...
granular
...
levels
...
of
...
conformance
...
and
...
participant
...
sophistication.
...
For
...
example,
...
the
...
assumption
...
of
...
adherence
...
to
...
a
...
centrally
...
curated
...
authoritative
...
source
...
of
...
information
...
models
...
and
...
terminology
...
is
...
no
...
longer
...
true;
...
the
...
infrastructure
...
must
...
gracefully
...
accommodate
...
local
...
terminologies
...
or
...
localizations
...
as
...
well
...
as
...
standard
...
terminologies.
...
It
...
must
...
enable
...
a
...
path
...
towards
...
"as
...
much
...
interoperability
...
as
...
is
...
possible"
...
between
...
any
...
two
...
parties,
...
rather
...
than
...
enforcing
...
full
...
"compatibility"
...
of
...
all
...
participants.
...
Additionally,
...
the
...
Semantic
...
Infrastructure
...
2.0
...
is
...
charged
...
with
...
making
...
the
...
wealth
...
of
...
knowledge
...
contained
...
within
...
the
...
numerous
...
SAIF
...
artifacts
...
available
...
and
...
consumable
...
(in
...
a
...
programmatic
...
fashion)
...
to
...
all
...
the
...
grid
...
participants.
...
Having
...
runtime
...
support
...
for
...
leveraging
...
this
...
information
...
to
...
inform
...
and
...
drive
...
service
...
interactions
...
is
...
a
...
key
...
value
...
proposition
...
for
...
the
...
future
...
platform
...
and
...
semantic
...
infrastructure.

...

The
...
key
...
components
...
of
...
the
...
Semantic
...
Infrastructure
...
2.0
...
are
...
still
...
being
...
identified
...
and
...
scoped.
...
The
...
Semantic

Infrastructure
...
Registry
...
has
...
been
...
identified
...
as
...
a
...
key
...
component.
...
It
...
is
...
expected
...
to
...
be
...
critical
...
to
...
the
...
grid.
...
The
...
Semantic
...
Infrastructure
...
Registry
...
may
...
ultimately
...
be
...
manifested
...
as
...
numerous
...
types
...
of

registries
...
and

services;
...
potentially
...
there

may

be

numerous

of

each.

The

ECCF

registry

provides

storage

for

the

semantic

components

of

ECCF

artifacts

as

specified

by

governance.

The

ECCF

Registry

will

be

populated

by

the

iterative

process

of

service

design

and

specification.
{info}
The
...
specification
...
of
...
a
...
CBIIT
...
enterprise
...
service
...
specification
...
requires
...
the
...
development
...
of
...
three
...
separate
...
artifacts:
...
The
...
CIM
...
(computationally
...
independent
...
model
...
specification)
...
The
...
PIM
...
(the
...
platform
...
independent
...
model
...
specification)
...
The
...
PSM
...
(the
...
platforms
...
specific
...
model)
...
specifications
...
The
...
CIM,
...
PIM
...
and
...
PSM
...
are
...
again
...
a
...
collection
...
of
...
artifacts
...
(models).
...
The
...
ECCF
...
matrix
...
is
...
placeholder
...
for
...
these
...
artifacts
...
organized
...
by
...
Reference
...
Model
...
of
...
Open
...
Distributed
...
Processing
...
(RM-ODP)
...
viewpoints
...
and
...
model-drive
...
architecture
...
(MDA)
...
perspectives.
...
Currently
...
a
...
Microsoft
...
Word
...
document
...
acts
...
as
...
a
...
template
...
or

placeholder
...
for

describing
...
the
...

Computation-Independent

(CIM),
...
Platform
...
Independent

(PIM)
...
and
...
Platform

Specific
...
Model
...
(PSM)
...
(along
...
with
...
the
...
artifacts
...
of
...
each
...
viewpoint),
...
while
...
the
...
future
...
semantic
...
infrastructure
...
will
...
define
...
computable
...
representation
...
formats
...
for
...
this
...
information.
...
Part
...
of
...
this
...
computable
...
representation
...
is
...
expected
...
to
...
be
...
a
...
Service-Oriented
...
Architecture
...
(SOA)
...
ontology
...
for
...
describing
...
various
...
entities
...
involved
...
in
...
the
...
numerous
...
conformance
...
assertions
...
(with
...
examples
...
including
...
but
...
not
...
limited
...
to
...
services,
...
operations,
...
data
...
types,
...
faults,
...
and
...
actors).
...
This
...
ontology
...
will
...
provide
...
the
...
backbone
...
for
...
reasoning
...
to
...
be
...
performed
...
by
...
the
...
platform
...
and
...
tools
...
at
...
both
...
runtime
...
and
...
design
...
time
...
(as
...
illustrated
...
later

in

this

Registry

...

Reliance

...

on

...

Platform

...

While
...
the
...
Semantic
...
Infrastructure
...
Registry
...
services
...
will
...
be
...
specified
...
in
...
ECCF,
...
and
...
potentially
...
manifested
...
on
...
multiple
...
platforms,
...
one
...
such
...
platform
...
will
...
be
...
the
...
grid
...
and
...
will
...
therefore
...
use
...
the
...
platform
...
as
...
scoped
...
in
...
this
...
document.
...
The
...
registry
...
will
...
require
...
numerous
...
capabilities
...
described
...
in
...
this
...
document
...
including
...
the
...
security
...
layer
...
for
...
items
...
such
...
as
...
authentication,
...
authorization,
...
auditing,
...
and
...
data
...
assertions
...
and
...
integrity.
...
The
...
infrastructure
...
may
...
also
...
require
...
support
...
for
...
a
...
rules
...
engine
...
capable
...
of
...
consuming
...
and
...
enforcing
...
rules
...
in
...
both
...
static
...
(for
...
example,
...
data
...
constraints
...
in
...
the
...
information
...
model)
...
and
...
behavioral
...
semantics
...
(for
...
example,
...
pre-conditions
...
and
...
post-conditions
...
of
...
operation
...
invocation)
...
stored
...
in
...
the
...
registry.
...
Similarly,
...
the
...
platform
...
will
...
inform
...
the
...
content
...
and
...
format
...
of
...
various
...
platform
...
specific
...
artifacts
...
to
...
be
...
stored
...
in
...
the
...
registry
...
(including
...
but
...
not
...
limited
...
to
...
XML
...
Schema
...
(XSD)
...
and
...
Web
...
Service
...
Definition
...
Language
...
(WSDL)).
...
The
...
platform
...
will
...
provide
...
the
...
capability
...
to
...
enforce
...
or
...
test
...
conformance
...
to
...
those
...
profiles
...
by,
...
for
...
example,
...
checking
...
service
...
interfaces
...
against
...
published
...
PSMs
...
and
...
doing
...
data
...
validation
...
against
...
published
...
information
...
models.
...
Finally,
...
the
...
platform
...
will
...
act
...
as
...
the
...
service
...
implementation
...
technology
...
for
...
the
...
grid
...
services
...
of
...
the
...
registry
...
(that
...
is,
...
be
...
the
...
management
...
interfaces
...
or
...
consumer
...
facing
...
services).
...

Platform

...

Reliance

...

on

...

Registry

...

The
...
platform
...
itself
...
will
...
require
...
and
...
leverage
...
numerous
...
capabilities
...
of
...
the
...
Semantic
...
Infrastructure
...
2.0,
...
most
...
importantly,
...
access
...
to
...
the
...
information
...
contained
...
in
...
the
...
ECCF
...
registry.
...
The
...
registry
...
will
...
facilitate
...
nearly
...
all
...
parts
...
of
...
the
...
service
...
development
...
and
...
consumption
...
life
...
cycle.
...
At
...
design
...
time,
...
the
...
registry
...
will
...
provide
...
a
...
wealth
...
of
...
information
...
to
...
the
...
designer
...
including
...
available
...
relevant
...
service
...
specifications
...
to
...
adopt
...
and
...
extend,
...
information
...
models
...
and
...
terminologies
...
to
...
leverage
...
for
...
new
...
operations,
...
and
...
formal
...
specifications
...
of
...
expected
...
behavior
...
of
...
the
...
existing
...
services
...
that
...
the
...
new
...
service
...
may
...
consume
...
from
...
in
...
its
...
implementation.
...
For
...
example,
...
service
...
templates
...
(shelled
...
out
...
implementation
...
artifacts)
...
could
...
automatically
...
be
...
constructed
...
based
...
on
...
platform
...
specific
...
specifications.
...
Extending
...
beyond
...
the
...
basic
...
query
...
and
...
retrieval
...
of
...
these
...
artifacts,
...
tools
...
can
...
be
...
built
...
to
...
actually
...
understand
...
the
...
semantics
...
of
...
this
...
information
...
and
...
aid
...
the
...
service
...
developer.
...
For
...
example,
...
potentially
...
relevant
...
information
...
models
...
may
...
be
...
found
...
by
...
entering
...
simple
...
terms
...
like
...
"tissue
...
sample"
...
into
...
a
...
tool,
...
which
...
binds
...
that
...
string
...
terms
...
to
...
concepts
...
in
...
identified
...
terminologies
...
and
...
locates
...
models
...
containing
...
information
...
bound
...
to
...
those
...
terms.
...
Similarly,
...
behavioral
...
contracts
...
may
...
be
...
discovered
...
based
...
on
...
terminology
...
binding
...
to
...
their
...
function
...
based
...
on
...
simple
...
search
...
terms
...
like
...
"data
...
insert,"
...
which
...
can
...
act
...
as
...
models
...
or
...
examples
...
for
...
new
...
service
...
operations.
...
Further,
...
such
...
"understanding"
...
of
...
behavioral
...
and
...
static
...
semantics
...
can
...
provide
...
a
...
powerful
...
feature
...
in
...
a
...
tool
...
for
...
workflow
...
or
...
service
...
composition.
...
It
...
could
...
leverage
...
this
...
information
...
to
...
make
...
suggestions
...
on
...
"next
...
steps"
...
in
...
a
...
workflow,
...
even
...
suggesting
...
specific
...
services
...
to
...
use.
...
It
...
could
...
also
...
provide
...
powerful
...
integrity
...
checking
...
of
...
the
...
data
...
flow
...
and
...
functional
...
effect,
...
by
...
validating
...
that
...
the
...
invocations
...
are
...
consistent
...
with
...
published
...
conformance
...
assertions
...
and
...
rules.
...
At
...
deployment
...
time,
...
the
...
platform
...
(or
...
deployment
...
tools
...
built
...
on
...
it)
...
can
...
automate
...
the
...
generation
...
and
...
execution
...
of
...
a
...
test
...
suite
...
to
...
check
...
conformance
...
assertions
...
published
...
in
...
the
...
registry,
...
relevant
...
to
...
the
...
service
...
being
...
deployed.
...
At
...
run
...
time,
...
the
...
service
...
can
...
provide
...
powerful
...
self-descriptive
...
metadata
...
by
...
referencing
...
profiles,
...
policies,
...
conformance
...
assertions,
...
and
...
specifications
...
in
...
the
...
ECCF
...
registry.
...
This
...
metadata
...
will
...
provide
...
significant
...
details
...
about
...
the
...
nature
...
and
...
behavior
...
of
...
the
...
service,
...
and
...
can
...
be
...
used
...
to
...
discover
...
it,
...
as
...
well
...
as
...
to
...
ascertain
...
programatically
...
how
...
to
...
correctly
...
consume
...
it
...
(and
...
validate
...
it
...
is
...
functioning
...
correctly).
...
The
...
platform
...
may
...
also
...
be
...
able
...
to
...
automatically
...
flag
...
non-comforming
...
service
...
instances
...
(for
...
example,
...
services
...
sending
...
incorrect
...
data,
...
or
...
running
...
outside
...
of
...
published

metrics)

behavior.
