Persistent Identifiers Workshop

Mankind has changed the gene pool of the food they are eating for centuries to perfection, but reduced diversity drastically...
... this has a negative effect when an old retro-virus found its way to alter the bio-engeneered crops, making them indigesible for human consumption.
The dried-out gene pool lacks the key to stop the deadly virus, which makes mankind an endangered species.
A serious question in 2305:
Thank God we still have the answer.
"Does anyone know where we left the DNA code for the original lemon back in the old days ?"
... we still have the answer
Phew... lucky them!
But we have to start building a trustworthy infrastructure that makes knowledge discovery possible, for now and in the distant future.

The researcher's perspective
What is this number
What can I use it for
Is is useful for me
Is it a burden on my existing work
Resolution, what is that
Ah, ... but where do I
have to go to resolve

Persistent Identifier Infrastructure
Autonomous Control
Serves Long Term Preservation
Research and Cultural heritage community
Duration: 1 year
Build on positive experience
A good start for international harmonising of PId solutions can be made by examining the urn:nbn (NBN) namespace for challenges and opportunities. The participating national NBN implementers, national libraries and/or national agencies responsible for long term preservation of cultural heritage and research information, have much experience and sound expertise with regard to URN-NBN PId that will be used for a global solution.
This applies to technical issues, to policy issues and governance models, and to information and user support.
Emphasis on policy and organisation
The national implementations are tailored to different national situations with different policies and laws. Joint development of policies and design of a management organisation is the core element in the project. This will ensure a stable and reliable infrastructure that meets commonly agreed user requirements, allowing partners to have their own local policy in place.
Existing practices will inform partners to define a business plan that supports a sustainable worldwide URN-NBN persistent identifier infrastructure.
Non proprietary solution
In order to avoid dependency on proprietary solutions, the global resolver policies and management organisation will be owned and controlled by the cultural heritage and research community members that participate in the project. The global resolver solution will develop common guidelines and criteria needed for an international transparent PId infrastructure.
Long term perspective
The one year project has four deliverables defined, but global long term preservation based on URN-NBN persistent identifiers will not be finished in one year. Therefore the project will also issue a roadmap towards further development, increased trust and participation of stakeholders and future services that will support the communities needs, such as comparison of usage statistics, global citation analysis, portals, enhanced publications (relations between objects), metadata interoperability facilities, global semantic thesauri, detection of duplicates, etc.
Recommendations will also address the (further) harmonisation with other PId systems.
Benefits and beneficiaries
Welding existing components together
International functionality
The NBN project will have a direct beneficial impact on the national URN-NBN communities. The national technical, policy and communication approaches will be enhanced and functionality of the URN-NBN system will be available at an international level.
Direct benefits for user community
The project will provide increased functionality to the listed target audiences:
•Those who assign PIds (e.g. content producers, authors, or organisations operating on their behalf)
This community will be able to make use of a globally recognized and harmonised URN-NBN system for reliable long term preservation.
•Those who use PIds for citation (e.g. content users, readers or organisations operating on their behalf)
This community will be able to refer to content/publications (e.g. for citations) in an easy and unambiguous way by using the URN-NBN PIds, knowing the citations will be globally recognised, unambiguous and available.
•Those who surf to information via a URN-NBN (e.g. web users, scholars)
This community will find URN-NBNs reliable actionable web-links that directs them to the expected information objects and will discover more services based on URN-NBN PIds.
Direct benefits for the URN-NBN
management organisations
The project will provide essential guidance for future development of a PId infrastructure:
•National IT governance organisations
will be able to discuss at a much higher level of expertise about necessary global solutions concerning permanent accessibility and traceability of information objects on the basis of international experience with a concrete NBN infrastructure. Some national responsibilities and/or procedures may benefit from economy of scale
Other benefits
Outside the URN-NBN domain this project will result in knowledge and experience to help harmonising URN-NBN with other PId systems, which in turn will lead to a worldwide solution for long term preservation, a benefit to all user communities.
This project will help move issues that have been a problem for several years. Upgrading and integration to an international level has been talked about a lot but got smothered in discussions about definitions and lack of targeted resources. The impulse of Knowledge Exchange having an interest may help achieve a global resolver solution.

Overall, practical experience will build trust and confidence. The collaborative effort will establish a more trustable PId infrastructure that can provide unambiguous and permanent accessibility in a transparent way. It will be governed and managed collaboratively on an international level, based on agreed policies aimed at maintenance, service provision and wide usage. National organisations will successfully cooperate and develop a shared infrastructure while maintaining their local implementations.
