PIDapalooza<https://pidapalooza.org/> is back! In January 2018, we will bring together creators and users of persistent identifiers (PIDs) from around the world to shape the future PID landscape through the development of tools and services for the research community. PIDs support proper attribution and credit, promote collaboration and reuse, enable reproducibility of findings, foster faster and more efficient progress, and facilitate effective sharing, dissemination, and linking of scholarly works. It is being organized by California Digital Library, Crossref, DataCite, and ORCID. PIDapalooza January 23-24, 2018 pidapalooza.org<http://pidapalooza.org/> Propose a talk<https://docs.google.com/forms/d/e/1FAIpQLSdR7TGVGMRUVVgMejMqJhgKa8xdL-GDGyv97g_RSRumBAjgTg/viewform?usp=send_form> If you’re doing something interesting with persistent identifiers, or you want to, come to PIDapalooza and share your ideas with a crowd of committed innovators. Conference themes include: 1. PID myths. Are PIDs better in our minds than in reality? PID stands for Persistent IDentifier, but what does that mean and does such a thing exist? 2. Achieving persistence. So many factors affect persistence: mission, oversight, funding, succession, redundancy, governance. Is open infrastructure for scholarly communication the key to achieving persistence? 3. PIDs for emerging uses. Long-term identifiers are no longer just for digital objects. We have use cases for people, organizations, vocabulary terms, and more. What additional use cases are you working on? 4. Legacy PIDs. There are of thousands of venerable old identifier systems that people want to continue using and bring into the modern data citation ecosystem. How can we manage this effectively? 5. Bridging worlds. What would make heterogeneous PID systems “interoperate” optimally? Would standardized metadata and APIs across PID types solve many of the problems, and if so, how would that be achieved? What about standardized link/relation types? 6. PIDagogy. It’s a challenge for those who provide PID services and tools to engage the wider community. How do you teach, learn, persuade, discuss, and improve adoption? What’s it mean to build a pedagogy for PIDs? 7. PID stories. Which strategies worked? Which strategies failed? Tell us your horror stories! Share your victories! 8. Kinds of persistence. What are the frontiers of ‘persistence’? We hear lots about fraud prevention with identifiers for scientific reproducibility, but what about data papers promoting PIDs for long-term access to reliably improving objects (software, pre-prints, datasets) or live data feeds? We believe that bringing together everyone who’s working with PIDs for two days of discussions, demos, workshops, brainstorming, and updates on the state of the art will catalyze the development of PID community tools and services. PIDs don't have to be boring...promise!
