Every

object

in

Fedora
...
has
...
a
...
Dublin

("DC")
...
Datastream.
...
The
...
following

triples

are
...
derived

from

its

content,

which

may

consist

any

number
...
of
...
each
...
of
...
the

15

elements.

If

unprovided

the

DC

will

be

automatically

created

with

(a

Note:

If

the

there

This

stated

though

it

that

be
