PIDapalooza 2020 in Lisbon, Portugal

PIDapalooza is the “Open Festival of Persistent Identifiers”, an international annual conference focused on research related persistent identifiers (“PIDs”). The conference has a unique flair – it places special importance on the interaction with the audience, and encourages experimentation and thinking outside the box in how to carry out presentations. This year the meeting took place in Lisbon, Portugal. Several presentations offered interesting viewpoints and information also relevant to the Finnish research information hub.

The Portuguese keynote talked about how they have created a national scheme where every student gets a student ID, to which all electronic documentation is tied. Several changes in legislation have been enacted to e.g. ensure that the electronic documents are legally valid, just like their paper predecessors. If the student continues onto a research career, the student id continues as a science id, to which all publications, research grants, and other scientific accomplishments and merits are tied.

One memorable presentation ( was performed in the form of a fairytale, in which the audience chose the path to follow. In addition to the innovative presentation format, it illustrated very well how important it is not only to create persistent identifiers but also to adopt the use of PIDs into common practices.

Based on the continuum of certain themes in the PIDapalooza conferences during the past few years, it is clear that not all, if any, of the issues are easily solved, and require international synergy and collaboration. And Pidapalooza is one of the main forums for doing exactly this. The efficient use of PIDs is one area that requires collaboration and communication. We have to be able to show the added value of using PIDs. One way to illustrate the benefits is to create a view on how to take advantage of connections.

The use of persistent identifiers is constantly evolving and this year the conference introduced some new ones. For example, identifying software source code (SWH-IDs, enables referencing and reusing source code in the future.

The InTRePID (, In-Text Reference Pointer Identifier, was also a new type of id introduced. InTRePIDs link to the context in where a reference is done, and calculate the potential significance of articles in a reference list since it can be meaningful whether a source is cited once or eight times during an article. The linguistic context of a citation can also be analyzed to determine the type of citation in question (e.g. supporting, contradicting). For such purposes, it becomes necessary to identify each occurrence of a citation in text.

The presentation “MERIL’s PIDdy Party!” ( on the other hand, told the familiar sad story about a project that was left without a proper business plan for continuity after the project funding stopped. MERIL worked on creating a European wide portal for documentation and discovery of research infrastructures (, developed in several FP7 and H2020 projects.

The Finnish Research Information Hub gave a presentation on “Unified Identifier Management and Resolution Services” focusing on the use of PIDs in the upcoming hub and a PID management service that is currently being developed at CSC. The audience gave input on the consequences of having several PIDs for the same resource and ideas about how to prioritize different identifier types.

These souvenirs brought again new viewpoints and plans on the table. Next year, the Research Information Hub will hopefully be able to share its best PID practices as well as the current dilemmas for the international experts to reflect and clarify.
