cence or duplication of effort, and offers searching and browsing tools to authorised users
to locate and retrieve the assets managed.
A DAM solution is likely to comprise of the following three broad components:
1.Archive
The archive is central to the DAM venture. It allows assets to be stored, manipulated,
re-used and re-purposed for future work, thus saving time and effort, and has the
obvious benefit of cost reduction.
2. Project Management tools
Specialised tools can facilitate collaboration between departments of an organisation,
or lead to smoother communications between the organisation and its external project
partners or customers.They will assist in further reducing costs associated with run-
ning collaborative projects, such as
postage and packaging, and other tradi-
tional forms of communication.
3. Rights Management
User permissions can be followed and
intellectual property rights tracked
automatically using Web crawlers/
spiders, image watermarking and object
steganography, which involves placing
an invisible, non-removable tracking
mark within the digital asset or its
associated, indivisible metadata.
End-to-end solution vendors, such as
Artesia
, with its TEAMS product,
speak of the need for a DAM product
that has the power to `ingest, index, categorize, secure, search, transform, assemble, and
export' content in as many forms as required. Each of these functions may be of particu-
lar interest and relevance to the cultural heritage community, as this report will outline.
Metadata: theory
A DAMS can provide tools for managing digital objects from creation, through publi-
cation and dispersal, and eventually on to the archive. Systems can automatically accept
the data output by the digitising process or accept input from other compatible systems.
They can assign storage positions and set and monitor management access, security, and
management attributes based on metadata assigned either by the object's creator or auto-
matically during the digitisation and ingest processes. It can store a digital entity or a
digital entity's location together with its metadata in a database.

Holding large digital objects (such as multimedia files) in a database is not yet as efficient as storing them
in a standard file system, so the filepaths of resources are often used to link the locations of such objects
with their corresponding metadata, and to identify the whereabouts of the object itself.
