PIDs in Data Infrastructures

Automatic Workflows

• most data is created automatically as part of workflowsmanual operations are exceptions

• at data creation time it is not obvious what their future life will be• later association with metadata and PIDs troublesome and costly

• thus immediate generation of metadata and PIDs as part of automatedworkflows

• data resources need to be referable and often citable (published) • need a reliable and highly performing machinery (registration +

resolution) based on stable standards

typically DOIs viaDataCite

typically Handles via EPIC

• assume that we have a recording of an extinct language and some annotations that tell us what someone said about medicine etc• researchers create relations that need to be preserved Video Recording

PID usage in our domain

Biological and cultural processes have evolved together, in a symbiotic spiral; they are now indissolubly linked, with human survival unlikely without such culturally produced aids as clothing, cooked food, and tools. The twelve original essays collected in this volume take an evolutionary perspective on human culture, examining the emergence of culture in evolution and the underlying role of brain and cognition. The essay authors, all internationally prominent researchers in their fields, draw on the cognitive sciences -- including linguistics, developmental psychology, and cognition -- to develop conceptual and methodological tools for understanding the interaction of culture and genome. They go beyond the "how" -- the questions of behavioral mechanisms -- to address the "why" -- the evolutionary origin of our psychological functioning. What was the "X-factor," the magic ingredient of culture -- the element that took humans out of the general run of mammals and other highly social organisms?

Several essays identify specific behavioral and functional factors that could account for human culture, including the capacity for "mind reading" that underlies social and cultural learning and the nature of morality and inhibitions, while others emphasize multiple partially independent factors -- planning, technology, learning, and language. The X-factor, these essays suggest, is a set of cognitive adaptations for culture.

• EPIC (European PID Consortium: CSC, SARA, GWDG, more) • large data centers with national/organizational (MPS) support• applying redundancy schemes (persistence, availability)• reliability, robustness, performance (registration, resolution)• all the same API (agreement on information associated)

• thus PID syntax not crucial but storing /finding information• feasible business model for science • security of administration DB for system• persistent and balanced governance for HS

• need a worldwide registry of agreed information types to feed our „stupid“ machines

EUDAT relying on EPIC + Handles

Information types in discussion

• multiple links to resources• checksum• link to metadata• citation metadata• RoR statement • mutability flag• persistency statement • pointers to presentation versions • provenance statement • collection statement • pointer to rights

• (support for parts/fragments) • (actionable PIDs)

- need agreements- need standard APIs
