Persistent Identifiers (PIDs)

Persistent identifier (PID) is a unique digital identifier associated with an object (person, organization, book, article, document, file, web page or other digital or physical object) and registered in a certain registration system. Registration in the system means that the link between the object and the identifier will be valid for a long time and information about the object will be found in the virtual space for a long time. Using a PID ensures that a digital reference to a digital or physical object will be valid even if the location of that object in the digital or physical space changes.

Many PID systems exist that are linked to very diverse objects: publications (DOI), datasets (Handle, DOI), individuals (ORCID), organizations (ROR), etc. Each of the systems has its own specific characteristics and features, strengths and weaknesses.

LiDA plans to develop and implement PID policies that will regulate the issuing of PIDs to different curated objects (data set catalogues, data sets and data files and related material) and the usage of other PID systems to document curated objects. Currently, “LiDA PID Policy for Data Sets” is being developed implementing project “Creating EOSC compliant Persistent Identifier (PID) policy for LiDA“.
