ARTAT- Partnership and Application Context
The experiment application will start with three
repositories
The ICCU istitutional repository named MAGTECA,
which is the grounding archive of the italian
national Digital Library Portal and
Cultural-Tourist Network (www.internetculturale.it
). It contains more than 2.000.000 of digitalized
images with the corresponding metadata
consolidated in more than 29.000 documents. The
metadata framework is encoded in MAG
(http//www.iccu.sbn.it/genera.jsp?id267).
Magazzini Digitali is a project undertaken by
Fondazione Rinascimento Digitale and National
Library of Florence (http//www.rinascimento-digit
ale.it/index.php?SEZ28) The selected objects
from the repository are Doctoral Thesis that are
harvested by the repository from the italian
universities institutional repositories. The
metadata framework is encoded in MPEG21-DIDL
(http//www.chiariglione.org/mpeg/standards/mpeg-2
1/mpeg-21.htm).
The digital repository of the Library Archive
of the British School at Rome which have digital
images of items from the collections of historic
photographs, prints and maps The digitalized
collections comprehend around 40.000 images with
more then 13.900 metadata documents.
(http//digitalcollections.bsrome.it/). The
metadata framework is encoded in METS
(www.loc.gov/standards/mets).

4.3. How are metadata and materials stored within
the preservation repository? For example, one
repository might zip metadata together with
content files and store the zip file as a single
entity. Another repository might store metadata
in relational database tables and content files
as individual entities in a file system. A third
repository might use multiple METADATA What
categories of metadata are (or will be) stored by
and used by your preservation repository? Please
check all that apply. __ rights and permissions
__ provenance (document history) __ technical
metadata __ administrative and management
information __ bibliographic/descriptive __
structural metadata __ other If you are using or
planning to use metadata elements from one or
more published scheme, which schemes are you
using? Please check all that apply. Does your
repository record information about these types
of entities? Please check all that apply.
Describe the sort of metadata that is (or will
be) recorded about each of these entities, giving
a few specific metadata elements as examples. __
collection __ logical object such as a book or
photograph __ non-digital source object __ file
__ bitstream (a bitstream may be equivalent to a
file, a subset of a file such as a binary object
embedded in a PDF, or greater than a file such as
a digital video stored in three parts) __
metadata __ other How is metadata obtained (or
expected to be obtained) by the preservation
repository? For example, is it submitted by
depositors, extracted automatically by the
repository's computer programs, other? If
different methods are used for different sets of
metadata, please note all of them. 5.6. How is
metadata stored and updated in your preservation
repository? If multiple methods are used, please
explain. __ in a relational database __ in an XML
database __ in an object-oriented database __ in
a proprietary database or format __ in flat files
__ bundled with related content files

CORE
a high impact event where not only the PML, but
also the objects and/or metadata objects have
been involved. In the last case, redundant
metadata probably will be involved and updated by
means of checking differences obtained by the
comparison of original AIPs metadata and PML
duplication metadata. The fact of changing the
original AIPs objects forces to find solutions
about the creation of new one AIP and how it
should be structured.
