Digital Object Architecture (DOA)
DONA Foundation and ITU
Information session
Com-ITU/CEPT - January 2016, Copenhagen, Denmark
DOA – Presence, Applications & Use
Global presence

Over 1,000 services built on DOA, in 75
countries, on 6 continents.

Today top-level DOA global root servers
receive avg. 200 million resolution requests
per month.

Assigned namespaces (“prefix”) +16,000.

DOA – An open architecture
Vendor-independent
Open source (free of charge)
Non-proprietary system
Based on official and/or popular standards (e.g. Digital Object
Interface Protocol as described in Recommendation ITU-T X.1255)
or protocols
Allows all vendors to create add-on products that increase
system’s:










flexibility,
functionality,
interoperability,
potential use,
and useful life.
An open architecture which enables the users to customize and
extend a system's capabilities to suit individual requirements.
An environment which enables different technologies to
interoperate.

DOA Features & Benefits
Interoperability of heterogeneous systems - The Digital Object

Architecture can be built around existing systems.
Enormous scale - the DOA can process billions of handle records.

The DOA makes this enormous data oversight extremely cost
efficient and easy to facilitate.

Multilingual support of all types of languages and scripts.

Quality of information - Information becomes a digital object and
therefore is resilient and persistent versa broken links of URLs.
Integrity & privacy of data - each Handle record has a

public/private key function for digital signature.

Solution using DOA framework
ITU Library and archives
Past challenges:



Need persistent identifier for its digitized documents
Need persistent identifier for web pages
Registered under prefix “11.1004/020.1000/”
Web pages and digitized documents are associated with a
persistent identifier, such as:



ITU conferences collection webpage


International Telegraph Conference (Paris, 1865)
