Digital Object Architecture DOA DONA Foundation and ITU
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 2 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: � � � � 4 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. 5

Solution using DOA framework Timeline overview 2015 • ITU-T Recommendations multilingual search tool 2014 Q 3 -4 • List of persistent • Patent statements, +2 000 digital objects • ITU-T active working groups • ITU Library persistent 2013 • ITU-T Test signals, +40 digital objects • ITU-T Recommendations supporting 6 languages and various format, +84 000 digital objects 7 identifiers to digital documents • ITU history portal web pages • ITU-T SGs persistent links (e. g. SG 15 liaison statements, Work programme, …) and selected handbooks identifiers for web pages and DVD-ROM with persistent documents related to the links Study Groups 2014 Q 1 -2 • ITU-T Recommendations • ITU-T Formal description resolution system, +1500 digital objects • ITU Publications persistent identifiers
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) � 8 http: //handle. itu. int/11. 1004/020. 1000/4. 1. 43. fr. 200
Leveraging DOA framework for new features Powerful search tool – PART 1/2 � ITU-T Recommendations search tool: � Index metadata in six languages � Room for tagging Recommendations � Prototype 9
