Other PIDs


IGSN ID (International Generic Sample Number) is a unique and permanent identifier for physical samples (e.g. rocks, water, soil). IGSN can be used as a standard method for their identification, citation and reliable localization.

The IGSN ID preserves the identity of the sample even as it moves from laboratory to laboratory and data appear in different publications, removing the ambiguity that results from similar sample names. IGSN ID allows researchers to track the analytical history of a sample and build on previously collected data when developing new procedures. In addition, IGSN ID provides a link between disparate data generated by different researchers and published in different scientific papers.

Example of IGSN ID: SSH000SUA. Information about this sample can be obtained via the URL of handle: http://hdl.handle.net/10273/SSH000SUA or DOI: https://doi.org/10273/SSH000SUA.

The IGSN is operated by the International Generic Sample Number Organisation (IGSN e.V.), an international registration agency. Organisations wishing to assign an IGSN must pay an annual membership fee to the IGSN e.V. Thanks to the partnership between IGSN e.V. and DataCite, IGSN IDs can now also be registered through DataCite and used in any industry to identify physical objects.

Registering an IGSN ID for a material sample links the physical world to the digital world, creating a long-term digital footprint that can outlive the sample itself. It provides proof that the sample exists and also preserves information that helps ensure that research investments are not lost and supports potential future research. This is particularly important for rare or unique samples.

The digital representation of the sample material is the landing page, which displays the sample description identified by the IGSN ID. The presentation of metadata on should include as many elements as possible to improve the findability and distinguishability of each sample. For example: sample images, sample location maps, relationships to other samples, related data, publications, organisations/persons.

In the DataCite metadata schema, IGSN identifiers allow a material sample to be linked to other entities by reference to their PIDs using relatedIdentifier and describe the nature of the relationship with the sample via relationType. IGSN identifiers are also functional links that can be incorporated into publications and datasets and linked to contextual information in online sample descriptions stored in metadata records or landing pages. They can also be included in the metadata of datasets, enabling their retrieval in research data repositories and metadata harvesting portals.

An IGSN ID can be assigned to a material sample at any stage of its life cycle, but the most effective way to avoid ambiguity is to use the IGSN ID as early as possible. It is strongly recommended to assign an IGSN to a material sample as soon as it is collected in the field or synthesised in the laboratory.

RAiD (Research Activity Identifier) is a persistent and globally unique identifier for research projects. RAiD is provided free of charge by the Australian Research Data Commons (ARDC). 

RAiD helps to track who is involved in a project, who is funding it, what the outputs of the project are and what tools have been used. RAiD thus allows all information related to a research project to be gathered in one place.

RAiD is based on a handle system. The RAiD handle is assigned via the RAiD API using the ARDC Handle Service or via the RAiD User Dashboard

Like ORCID, RAiD includes a modifiable record and the ability to add or change content without having to version the ID itself. Each new entry is time-stamped. In addition, the source of the new information is captured, if available.

RAiD offers flexible openness management, while sensitive data can remain closed.

Metadata contains descriptive information about the project (e.g. grants, organizations, collaborators, articles, etc.). Metadata can also include other persistent identifiers – e.g. ORCID for researchers associated with the project, DOI for funding grants, ROR for research institutions.

Information on other persistent identifiers will be added over time.
