I learned about a workshop discussing ideas around persistent identifiers held in the Netherlands last month as a result of seeing an email from Andrew Treloar @atreloar (Australian National Data Service – ANDS). This workshop organised by the Knowledge Exchange was a seminar to pay:
“attention to the usage of PIDs for publications, and increasingly for data, and for combinations of text, media and data. Also the relation with Author Identifiers was discussed. Standardisation and specifications for transparency between systems was addressed. In break out sessions participants discussed the benefits and challenges in operating multiple persistent identifier systems and the relation of persistent identifiers to Linked Data.”
This grabbed my attention because of some of the discussions both semantic and technical at #lodlam back in May and some of the architectural conundrums facing linked open data enthusiasts.
“more than 40 experts involved in various Persistent Object Identifier (POID) communities met for a Knowledge Exchange seminar to discuss the challenges and opportunities involved in interoperability between multiple PID-systems. Three major systems – Handle, URN:NBN and DOI – presented their current state of affairs and examples of their systems in practice….”
The presentations from this seminar are online and provide some food for thought for the techies thinking around how to set up IDs in linked open data systems.
So I figure this community if it isn’t already aware of this discussion might like to be. I know this is a conundrum that many of those involved with undertaking ANDS funded projects are trying to get their heads around what identifier systems to use and there has been a heap of documentation made available on the ANDS website in an effort to support this. There is information to guide those into the area of system identifiers; there are several pages designed to inform the newby, familiar, and the expert on persistent identifiers, and there is a focused page on DOI (Digital Object Identifiers).
If you’re interested to know more about the Party Infrastructure soon to be launched in Australia through the National Library of Australia, keep your eye on the NLA Party Infrastructure project wiki.
I hope some of this information comes in handy!
