Description
Safeguarding
Agenda for the call and notes can be found at https://w3c.openactive.io/meetings/2019-09-11-safeguarding-and-the-opportunity-specification.
A
Welcome
welcome
back
to
the
w3c
meetings.
You'll
all
have
seen
the
agenda
circulated
yesterday.
I
hope
so.
Yes,
the
main
topic
of
the
call
as
Nick
is
just
alluded,
is
probably
going
to
be
the
safeguarding
aspect
of
the
opportunity
specification
but
I
think,
possibly
because
we
would
actually
quite
a
large
call
today.
Possibly
a
round
of
introductions
would
be
in
order,
so
all's
I'll
start
I'm
Timothy,
Hill
data
standards
and
technical
lead
for
open
octave
as
a
whole,
and
if
we
can
just
go
around
in
a
circle
that
would
be
great
I.
E
G
A
A
A
A
Now
I
think
one
of
the
first
conversations
we
probably
need
to
have
is
going
to
be
about
scoping.
In
fact,
we've
had
a
few
conversations
around
this
and
there
seem
to
be
a
few
different,
relevant
senses
of
the
word,
safeguarding
that
we
might
have
to
think
about
a
little
bit.
You
just
starts
screen
sharing
again
here.
A
B
A
E
E
To
jump
in
and
then
the
lady
on
the
prom
teleprompter
on
the
train,
interrupted
so
yeah
apologies
if
I
cut
out,
but
the
reason
why
I
kind
of
brought
this
the
group
was
numerous
conversations
that
I've
had
with
active
partnership,
local
authorities
who
all
want
to
encourage
their
smaller
providers
to
open
their
data
and
through
tools
such
as
open
sessions
and
then
comes
the
realization
that
and
some
of
the
bigger
activity.
Finders
change
for
life,
for
example,
was
not
accepting
sessions
from
individual
operators.
E
H
A
E
I
E
Add
I
had
a
conversation
with
Izzy
from
Sport
England
this
morning
and
she
wanted
to
make
this
call,
because
there
is
some
work
happening
at
Sport
England
around
safeguarding,
so
it'd
be
worth
picking
out
with
them.
Unfortunately,
can't
be
represented
on
the
call
today,
but
touching
base
with
what
they
have
already
in
place
and
if
there's
any
way
to
incorporate
it.
G
G
So
there's
nothing
in
place,
but
we
are
certainly
kind
of
keen
to
explore
options
for
that
and
kind
of,
particularly
we've
seen
a
few
different
use
cases
so,
looking
at
more
stuff
around
social
prescribing,
getting
lots
of
feedback
from
social
prescribers
that
they'd
want
to
be
have
some
element
of
confidence,
trust
and
knowledge
about
their
qualifications
or
the
suitability
of
a
activity
provider
to
for
them
to
actually
use
open
data.
So
it's
definitely
a
couple
of
use
cases
that
we're
interested
in
okay.
B
Actually,
so
you
may
have
seen
that
about
something
else,
but
they
they're
building
an
activity
find
in
Manchester
wide
it's
going
to
around
for
the
local
leisure
operators,
and
also
lots
of
smaller
providers
to
to
be
bookable
in
one
place
for
Manchester
and
that's
going
to
be
called
MC
our
actives,
the
challenge
they
have
with
that
is
obviously
to
but
they're
their
brand
to
it.
They
wanted
to
make
sure
that
every
provider,
small
and
large
that
was
on
there
was
did
have
a
level
of
something
like
safeguarding
certificate
or
whatever.
B
It
is
that's
necessary
to
give
them
confidence
that
these
promoters
are
well-intentioned
and
well
equipped
to
deal
with
vulnerable
adults
and
children
specifically.
So
the
work
that
was
to
actually
they've
they've
got
three
trust
levels.
They
call
them
which
they
associate
with
different
providers
and
and
also
some
actually
specific
activities
for
certain
providers.
So
it
might
be
that
a
Zumba
instructor
gets
gets
just
a
trust
level
two
for
some,
but
not
if
they
started
to
run
classes.
B
G
B
A
G
A
B
C
A
A
B
Talking
to
EMD
earlier
again,
I,
don't
think
shells
may
be
showing
the
call
either
no
she's,
not
so
EMD
had
mentioned.
There
were
a
number
of
different
qualifications
with
NAMD,
it's
quite
diverse,
different
qualifications,
it
exists,
but
it
basically,
the
idea
of
this
spec
is:
let's
assume
the
qualifications
that
this
certain
kind
of
certification
is
decentralized.
That's
the
first
assumption.
Second,
assumption
is:
let's
assume
that
that
there
is
a
level
of
trust
worthiness
of
these
sources
of
accreditation
themselves,
so
they
do
some
kind
of
manual
checking.
B
These
aren't
just
like
documents
that
you
upload
with
your
session,
because
if
the
documents
can
be
uploaded
with
the
session,
then
the
approach
here
doesn't
really
make
any
sense,
because
it's
all
just
self-certified
stuff.
However,
if
it's
the
case
that
there
are
bodies
that
like
MCR
and
we
thought
mark
were
but
maybe
maybe
it's
decentralized
now,
some
of
the
ng
B's
are
and
actually
are
credible
sources
and
I
think
BBC
get
inspired
used
to
do
this
when
it
existed
is
to
that
the
clubs
they
accept
it
on
so
they're.
D
B
Know
actually
in
Barry
there's
something
similar
with
the
project
they
have
their
key
ballot,
which
is
I,
will
if
you
will
and
they
had
an
accreditation
person.
So
so,
let's
assume
that
that
person
exists.
That's
a
credit
certification
publisher
and,
on
the
other
side,
you've
got
the
opportunity
data
publisher,
like
open
sessions
or
book.
B
When
so,
the
idea
is
that
if
the
sessions
are
published
in
open
sessions
and
they're
available
for
anyone
to
access
using
share,
then
someone
can
externally
put
a
stamp
of
approval
on
one
of
those
organizations
and
a
subset
of
their
sessions
or
all
of
their
sessions.
To
say,
I
trust
this
organization,
and
they
can
do
that
stamp
for
approval
in
a
way
that
can't
easily
be
forged.
So
that
lets
say
MC
are
active,
approves
an
open
sessions
organizer.
B
That
is
something
that,
then,
is
it's
not
it's
not
easy
for
someone
to
pretend
to
be
that
organizer,
and
so
that's
something
that
is
quite
robust
and
we
can
then
trust
as
you're
when
you're
consuming
both
of
those
data
sources
and
you
can
combine
them
together.
So
a
feed
of
certifications
on
the
one
side
and
a
feed
of
sessions
on
the
other,
and
you
can
merge
those
two
which
gives
you
that
confidence
that
you
know
and
you
can
filter
things
that
are
accredited
or
not.
Does
that
make
sense
so
far.
E
B
Sure,
okay,
so
certification,
publisher,
opportunity,
publisher,
that's
the
idea,
so
just
without
looking
at
the
code
too
deeply,
because
we
don't
need
to
get
into
this
huge
amount
technical
detail,
but
to
give
you
a
sense
of
what
the
certification
publish
would
publish
they
publish
two
things.
The
first
thing
they
published
is
what's
called
a
scheme.
The
scheme
is,
and
I
mean
it
can't
just
be
made
up
by
the
certification
published
depending
on
whatever
certifications.
They
have
it's
just
basically
a
list
of
certifications.
They
could
be
levels,
they
could
be
anything
really
any
kind
of
badge.
B
That
is
useful.
Incredible.
Those
badges
come
with
the
URL
that
links
through
to
what
the
requirements
and
criteria
are
for
that
badge
and
how
trustworthy
is
so
there's
those
badges
can
then
be
put
on.
Websites
like
get
active,
will
change
for
life
or
wherever
there's
a
logo
for
the
badge.
So
you
can
actually
render
it
as
a
badge
if
you
wanted
to-
or
just
put
the
name
of
it,
there's
a
name
as
well.
So,
for
example,
level
3
for
MCA
are
active.
B
B
So
that's
the
first
thing
you
publish
the
levels
and
the
second
thing
is
you
publish
the
list
so
if
anyone's
familiar
with
the
are
pde
kind
of
open,
open
standards
that
exist
at
the
moment
for
them
for
publishing
opportunity
data,
it's
exactly
the
same
thing.
Instead
of
a
feed
of
events,
though
you're
just
publishing
a
feed
of
certificate,
certifications
which
is
basically
a
link
between
an
organizer
and
a
certification
level.
B
So
in
this
example
we're
using
book
when
and
basically
saying
that
book
when
organizer
to
4601
is
level
4
by
change
for
life's
level
levels,
but
they
might
have,
and
so
all
we're
really
publishing
is
just
a
connection
between
those
two
things
and
the
reason
that
can't
easily
be
forged
is
that
the
organizer
URL
there
is
actually
the
ID.
That's
in
the
feed
from
book
1
or
from
open
sessions,
that's
the
ID
of
the
organizer
within
those
systems,
and
so
as
long
as
those
systems,
those
organizer
IDs
can't
be
reused,
which
wouldn't
be
the
case.
B
So
if
that
would
be
sorry
that
would
be
the
case
if
you
were
using
like
an
incrementing
integer,
for
example,
you
would
just
you
know:
everyone
gets
an
ID
used
to
be
the
next
IDs.
You
would
never
get
an
existing
ID
reused
by
different
organizations.
So
that's
the
identifier
that
gets
certified
and
so
they're
the
two
things
that
gets
published
and
then
the
question
is
well.
If
you
still
running
one
of
these
certifications
for
self
service
form,
how
do
you
make
it
really
easy
for
someone
to
actually
upload
their
session
document?
B
Sorry,
their
certification
documents,
so
the
flow
the
MC
are
active
or
thinking
about
is
something
like
you
go
in.
You
say
I'm
a
provider
in
Manchester.
They
say
what
sessions
do
you
run?
Is
it
for
children,
children
of
vulnerable
adults?
Is
it
just
for
adults?
You
select
that
it
says
right,
you
too,
and
it
says
which
activities
do
you
run
it
for?
You
select
that
and
it
says
which
these
are
the
documents
you
need
to
upload.
B
You
upload
those
documents,
and
the
next
step
is
where
your
sessions
published,
and
it
will
ask
you
for
it
will
ask
you
to
paste
in
the
URL
of
the
page
that
your
organization's
page
on
book,
when
so
it's
just
like
paste
in
the
book
and
maybe
there's
a
little
in
a
diagram
to
explain
how
to
do
this.
You
just
find
the
the
organization
page
on
open
sessions
or
book
when
and
you
can't
be
paste.
B
B
B
So
if
I'm
Co
active
can
easily
just
read
that
page
and
check
that
it's
a
valid
page
in
that
ID
is
valid
and
it's
the
robust
identifier.
So
it's
just
a
small
amount
of
validation
which
will
be
enough
to
to
create
that
that
link
and
then,
of
course,
anyone
who's
consuming
that
consuming.
The
data
can
take
that
ID
from
the
open
sessions
feed
or
from
the
book
when
feed
and
link
it
to
the
ID
that
exists
in
the
list
of
trust,
certifications,
feed
and
there
you
go
that's
so
that's
that's
I
think
is
one
one.
B
B
Mc
are
active,
which
means
that
if
you
were
an
organization
that
maybe
didn't
want
to
go
through
and
let
all
of
these
individual
schemes
you
just
wanted
to
pick
one
you
trusted
like
club
Marc,
you
might
then
be
able
to
infer
other
or
EMD.
Maybe
you
might
be
able
to
infer
all
the
other
types
of
accreditation.
B
B
I
should
have
mentioned
that
you
can
supply
and
as
the
accreditation
body,
a
list
of
activities
and
an
age
range
for
which
certification
is
valid
and
so
just
yeah.
The
last
example
in
that
list
there.
So
here
you
can
see
you
can
say
this
is
only
valid
for
body
pump
and
it's
only
valid
for
activities
relevant
for
over
a
teams
and
yeah.
B
B
Yeah,
it's
a
good
question.
I
guess
this
is
quite
a
light
touch
I
mean
it
might
be
that
we
can
provide
a
tiny
bit
of
open
source
code
that
does
the
validation
of
the
ID
bit.
That
they'll
all
need
to
do,
obviously
when
they
paste
that
ID
in
to
help
with
adoption.
But
apart
from
that,
it's
just
a
case
of
kind
of
I
guess
if
they've
already
got
a
big
database
of
all
the
people,
they
trust.
This
is
just
basically
a
feed
of
that
database,
as
other
communities
are
so
yes,
there
may
be.
B
The
work
involved
is
quite
minimal
and
maybe
would
be
the
small
addition
of
this
kind
of
check
box.
There's
some
by
deep
thing
you
face
in
which
we
might
be
able
to
help
of
the
libraries
we
know.
Nc
are
active
a
very
keen
to
do
this
and
I
guess
that's
why
that's
what's
kind
of
driven
this
to
a
appointment?
Maybe
we
should
do
this
spec
now,
because
we've
been
talking
about
this
kind
of
thing.
B
The
years
not
actually
had
a
driver
to
do
it,
but
obviously
with
Interactive's
and
project
is
about
to
kick
off
and
that
this
is
a
cool
thing
to
them.
They
would
certainly
be
keen
to
provided
a
set
I
think
and
we
transport
England
about
these
other
schemes.
We
need
to
have
a
quick
chat
to
a
few
different
organizations
who
are
publishers,
maybe
bring
some
of
them
on
that's
cool,
just
check
that
they're
happy
and
you
know,
they've
got
longevity
to
their
schemes.
They're,
not
like
winding
down
I,
wonder.
G
B
Essentially,
is
probably
probably
badminton
netball
and
swimming
at
the
obvious
ones,
because
they're
they're,
already
data,
that's
decentralized,
triathlon
orienteering
and
cycling
actually
have
their
own
data
sources
for
most
of
the
sessions
just
in
the
UK
and
although
that's
not
exclusive.
Obviously
that
can
be.
You
can't
build
a
cycling
sessions
on
open
session,
so.
D
It
feels
like
a
small
standalone
server
to
produce
this
feed
would
be
useful
as
a
reference
for
someone
building
into
other
systems
and
also
for
smaller
organizations.
Even
if
it's
something
whereby
you
put
a
URL
in
it,
it
then
opens
that
in
a
new
tab
and
you
check
it
and
then
there's
some
checkboxes
for
you
to
say.
Yes,
it's
this
that
and
the
other,
and
then
that
just
puts
it
into
a
local
database
that
they
can
provide
the
field,
because
small
organizations
they
could
literally
just
get
that
set
up
and
that's
their
field.
D
So
this
is,
you
need
something
that
can
provide
the
accrediting.
Accrediting
organization
needs
to
provide
a
feed
of
things,
they've
accredited
yeah
as
a
small
organization.
If
I
have
some
kind
of
thing,
I
can
login
to
I
can
paste
in
a
URL
to
it
and
then
say
yes,
I
prove
this
that
and
the
other,
and
then
it
generates
the
accredited
fee
from
that
set
of
URLs
I
can
go
and
delete.
Something
I
can
manage.
D
B
D
Or
just
put
in
URL
one
by
one
for
yeah
bulb
loading
would
be
nice
as
well,
but
the
real
value
on
an
ongoing
basis
seems
to
be
able
to
check
the
box
to
say
yes,
this
is
overrating
only
this
is
of
this
type
of
that,
otherwise
everything
is
going
to
be
a
generic
theater.
Yes,
we
approved
everything
from
this
site
which
might
be
fine
in
some
cases,
but
it
only
needs
something
for
some
provider
to
take
there.
B
A
A
B
A
B
A
B
Yeah
exactly
Omni,
basically
wait.
They
might
have
one
badge,
they
might
have
five
yeah.
They
might
give
up
multiple
badges
as
long
as
because
I
suppose.
The
other
thing
is
that
we
don't
know
what
the
native
users
are
going
to
want
to
filter
on
which
which
schemes
they
trust
so
I
guess
as
long
as
they're.
These
are
all
published
and
people
can
make
informed
decisions
about
which
schemes
they'll
accept,
which
also
seems
to
be
from
what
I'm
from
this
some
of
the
chance
I've
had
on
this.
B
It
seems
that
that
actually
is
a
fairly
complex
questions
is
not
just
use
that
list.
They
need
to
understand
how
what
the
processes
are
behind
it
and
it's
processes
efficient
and,
if
there's
a
problem,
if
they
can
actually
actually
contact
the
organization
to
get
hold
of
the
original
certificates
that
we
used
in
the
yeah.
That
kind
of
thing,
so
some
two
ends
up.
If
you
go
to
the
enth
on
it,
I
think
they
probably
need
probably
quite
high
trust
relationships
between
the
trust
organizations.
B
She
said
I
mean
right
between
between
the
users
and
the
trust
organisations,
but
if
you're
just
at
the
kind
of
casual
level
of
a
bit
like
changing
for
life,
it's
like
can
we
make
this
slightly
better
they're,
just
putting
a
warning
on
the
website,
then
yeah.
This
is
probably
where
you
can
take
the
warning
off
and
put
a
badge
on.
Instead.
B
B
They're,
going
to
do
things
like
check
that
the
where
they
can,
where
they
have
relationships
in
place
with
booking
systems,
check
that
the
sessions
aren't
canceled
too
often
things
like
that,
and
if
a
writer
cancels
their
own
sessions
three
times
in
a
row
that
they
lose
the
badge
so
really
quite
and
I
think
they're
going
to
do
that
by
checking
the
feeds
not
entirely
sure
what
they
gonna
do,
but
yeah.
So
so
something
I
guess
take
there.
B
Let
this
source
idiot
of
a
quality
assurance
exercise
as
well
as
just
some
doesn't
the
relevant
documents,
but
so
so
to
that
end,
doesn't
have
the
beginning
levels
in
there.
The
accessibility
information
is
that
accurate
probably
falls
under
that
a
little
bit
I
guess
if
there's
an
accessibility,
accreditation
body
that
could
be
an
interesting
thing.
So
what
FTS?
All
these
versions
are
rebranded
and
I've
forgotten
all
the
new
name.
So
whatever
FGS
became
accessibility
Alliance
they
may
want
to
do
the
same
thing
and
accredit
things
themselves.
B
I
guess
we
should
bring
up
a
conversation
separate
to
categorizing
things.
But
yes,
it's
definitely
it's
a
good
point.
I
suppose
we
should
probably
have
at
least
one
conversation
with
those
guys
around
this
identify,
if
that's
something
Indians
didn't
do
thing
and
but
I
suppose
at
least
a
suit
or
a
generic.
Then
it
doesn't
need
specific
kind
of
connections.
B
Yeah
totally
and
in
fact
you
could
probably
extend
quite
easily
the
the
activity
and
age
filters
we've
gone
there
to
accessibility
supports
as
well,
so
that
you
could
say
you
know
if
something
is
suitable
for
visually
impaired
people
and
here's
the
certification
that
says
they
know
how
to
deal
with
blind
dogs.
As
with
guide
dogs.
B
A
Yeah
this
was
equally,
it
could
apply
to
a
scenario
like
competence
of
instruction
up
to
a
certain
level
so
that
the
martial
arts,
for
instance,
yeah,
can
instruct
yellow
belt
came
again.
It's
just
a
question
of
an
authority
and
having
fun,
and
that
would
I
guess
the
only
the
only
thing
that
would
have
to
change
is
that
probably
we
need
to
think
about
really
about
safeguarding,
although
that
will
be.
A
G
And
can
hear
me
out
right
now,
yeah
much
better
okay
and
for
a
person
who
is
on
open
sessions
and
they
are
uploading
a
table
tennis
session
and
say
they've
already
got
accreditation
with
table
tennis
England
and
if
the
both
systems
are
working
perfectly.
Who
would
who
actually
makes
that
link
between
the
organization
and
the
current
accreditation
provider,
always
at
Table,
Tennis
England?.
B
B
Yeah,
because
because
it
probably
is
on
them
to
go
to
table
sinners,
England
and
then
you
know
apply
for
accreditation
to
be
recognised
there
after
they
go
to
open
sessions,
because
that's
the
URL
link
is
that
way
around
you
have
to
on
Table
Tennis
England.
They
have
to
see
the
open
session
staff
and
then
approve
it.
B
So
if
you've
got
well
or
even
that's
been
given
to
you
and
you
just
go
in
a
cupboard
somewhere,
so
you've
got
Telus
England
saying
yet
your
this
is
your
certificate,
just
uploading
that
as
documents
providing
it
or
even
its
tables,
this
image
on
their
website
and
just
got
a
big
list,
I
suppose
you
would
still
need
to
go
to
table
settings
and
associate
your
open
sessions
page
with
the
organization
they
recognized
you
as
in
table
tennis.
England
sounds
like:
do
you
have
to
go
to
Table,
Tennis
England,
so
I?
B
Guess
it's
just
a
question
there
about
how
how
we
realistically
signpost
people
to
know
what
accreditation
they
need,
because,
basically,
if
you
Yossi
was
saying,
if
you
put
your
stuff
open
sessions,
that's
not
the
end
of
your
journey.
You
might
need
to,
depending
on
the
activity
you've
selected,
that
you
know
you
might
have
a
relevant
certification
or
the
area
you're,
providing
universe
in
Manchester
or
something
you
might
have
a
relevant
certification.
What
you
should
seek
out
to
try
and
get
yourself
ticked
off,
yeah.
G
I
mean
I'm
wondering
like
you
could
in
the
future,
get
it
to
a
point
where
open
sessions
recognizes
the
activity
type
that
you've
put
in,
and
then
you
get
to
the
end
of
the
flow
of
upload.
Again
it
says,
would
you
like
to
submit
this
to
Table,
Tennis
England
and
then
goes
through
to
the
way
if
they
have
a
scheme
up
and
running
yeah
customer
journey
from
uploading
it
to
submitting
it
to
the
certification
provider?
Okay,
yeah.
B
That'd,
be
great,
I
mean
actually
that's,
probably
a
yeah.
That
probably
is
something
that
I
don't
know
what
the
end
point
looks
like
you're
hitting
when
that
last
step
happens,
but
there's
probably
something
additional
needed
so
that
you
can
seamlessly
move
from
open
sessions.
I
guess
the
assumption
with
respect
as
written
is
that
the
open
session
wouldn't
do
anything
special
apart
from
just
that
little
bit
of
HTML
code
but
I.
Guess
if
you
wanted
to
yeah
massively
optimize
the
journey
there,
then
yeah.
That
would
be
good.
B
G
B
Then,
if
you've
consumed
one
to
have
schemes
yourself,
you
could
then
recommend
which
scheme
and
the
obviously
the
scheme
it
should
have
like
a
submission
URL
that
someone
can
just
go
to
to
send
them.
So
you
sure
to
kind
of
so
I
guess
adding
those
two
things
that
would
probably
allow
for
that.
Yeah.
G
A
I
B
Well,
I
would
say
yeah
if
everyone,
when
we
talk
to
the
other
bodies
it
works.
Certainly
this
has
been
a
product
of
lots
of
conversations
over
a
long
period
of
times.
I
feel
like
this
is
just
just
a
very
very
easy
summary
lots
of
iterative
thinking
but
yeah
nice
to
have
a
way
to
go
yeah.
We
something
should
have
a
further
few
conversations
with
Izzy
with
Cod
mark
people,
all
with
some
of
their
than
GPS
yeah.
C
A
A
B
Yes,
so
this
is
about
allowing
a
someone:
who's
got
a
membership
already
at
yellow
or
another
site,
for
example,
to
to
another
provider
to
use
that
membership
when
they
make
a
booking
through
open
booking.
To
do
that,
they'll
need
to
first
use
some
soil
or
flow
to
verify.
They
are
indeed
a
member,
the
member.
They
say
they
are
using
M
passwords
for
the
membership
and
when
that's
happened,
you
get
that
member
ID
and
then
the
idea
here
is
that
you
can
still.
B
B
G
B
Yeah
and
so
on
this
one,
this
is
potentially
started
more
generic.
Actually,
if
you've
got
because
there's
a
situation
with
open
booking
where
you
might
be
logged
in
on
change
for
life
and
have
a
user
ID,
but
two
legends
or
or
open
sessions,
you're
a
guest
and
you're,
not
you're,
not
you
don't
have
a
login
to
legend
as
such,
so
you're
you're
a
guest
as
far
as
legends
concerned,
but
you're,
a
known
user.
B
B
If
has
changed
for
life
you're
comfortable
to
do
so
as
an
optional
field,
so
that,
if
you're
doing
analytics
on
the
booking
system,
you
can
see
repeated
trends
of
users
doing
things
because
that's
the
same
user
twice,
they
might
be
the
same
guest
user
twice.
But
you
can
you
can
that
way?
You
can
reference
that
that's
the
same
guest
user!
That's
some
that's
yeah
and
then,
if
there's
any
interesting
behaviors
you
can
learn
from
from
that
user
and
and
what
they're
purchasing
and
how
that
and
which
which
contents
they're
coming
through
things
like
that.
B
So
I
was
the
idea
and
also,
of
course,
for
children.
It
means
that
if
you
don't
have
an
email
address,
that
ID
can
be
used
in
place
of
a
unique
identifier
as
an
email
which
is
the
cornea
current
mandatory
for
making
your
booking,
but
for
the
attendees
themselves
and
keep
put
in
a
child's
first
name,
and
certainly
you
could
use
this
identifier
as
well
to
identify
that
child
yeah.
