...

An

...

understanding

...

of

...

metadata

...

standards

...

and

...

profiles

...

is

...

critical

...

to

...

a

...

successful

...

distributed

...

cataloging

...

strategy

...

that

...

will

...

result

...

in

...

useful

...

client

...

applications

...

of

...

the

...

technology.

...

CSW

...

servers

...

can

...

return

...

any

...

number

...

of

...

metadata

...

standards

...

in

...

a

...

search

...

or

...

harvest

...

operation,

...

and

...

applications

...

written

...

to

...

use

...

the

...

CSW

...

service

...

methods

...

need

...

to

...

"know"

...

what

...

they

...

are

...

getting

...

in

...

a

...

few

...

key

...

areas.

...

Some

...

policies

...

may

...

need

...

to

...

be

...

put

...

in

...

place

...

across

...

instances

...

of

...

the

...

technology

...

stack

...

so

...

that

...

there

...

are

...

general

...

rules

...

of

...

the

...

road

...

that

...

everyone

...

understands.

...

For instance,

...

we

...

may

...

want

...

to

...

specify

...

that

...

every

...

metadata

...

record

...

returned

...

by

...

CSW

...

is

...

identified

...

with

...

a

...

universally

...

unique

...

identifier

...

(UUID)

...

so

...

that

...

search

...

and

...

harvest

...

operations

...

can

...

tease

...

out

...

duplicates.

...

In

...

this

...

same

...

vein,

...

we

...

may

...

want

...

metadata

...

from

...

CSW

...

servers

...

to

...

support

...

some

...

search

...

criteria

...

or

...

server

...

configuration

...

that

...

will

...

serve

...

only

...

the

...

unique

...

records

...

that

...

call

...

that

...

particular

...

instance

...

"home"

...

as

...

opposed

...

to

...

other

...

records

...

that

...

may

...

be

...

harvested

...

onto

...

that

...

server.

...

If

...

vocabularies

...

of

...

terms

...

are

...

important

...

to

...

a

...

particular

...

collection

...

of

...

metadata

...

and

...

applications

...

that

...

use

...

those

...

metadata,

...

we

...

may

...

want

...

to

...

specify

...

that

...

controlled

...

vocabulary

...

sources

...

be

...

identified

...

to

...

a

...

particular

...

registry

...

in

...

a

...

particular

...

way

...

so

...

that

...

the

...

authorities

...

can

...

be

...

understood

...

by

...

any

...

application.

...

All of these considerations may provide a useful focus for the Metadata Team.
