Researcher IDs - An essential way to establish and maintain your digital identity

Definition: What is a researcher identifier (or author identifier)?

A researcher identifier, often referred to as an author identifier, is a unique and permanent alphanumeric code that serves to distinguish you unequivocally as the author of a publication. Over the course of your professional journey, your identity may undergo changes that result in ambiguity, such as name changes due to marriage, the use of pseudonyms, the presence of individuals with similar names, or variations in abbreviations and alphabets. Consequently, discerning who is who and tracking their contributions can become challenging. Author IDs play a pivotal role in resolving these issues by providing a definitive means of self-identification.

Significance:Author identifiers empower you to exercise greater control over your digital identity.

The researcher identifier ecosystem:In the realm of research, researcher identifiers are growing in both significance and abundance, making it increasingly complex to navigate this landscape. Several identifiers are automatically assigned by publishers or platforms, while others require application, giving you greater authority over your digital footprint. Prominent examples include ORCID and Idhal, which require visits to their respective platforms for creation. Both identifiers work hand in hand. ORCID is a non-profit organization with a broad international membership base, including Inria. Integration possibilities abound. On the HAL platform, for instance, you can link your ORCID identifier to further bolster your digital identity, or seamlessly incorporate your HAL deposits into your ORCID account. Given Inria’s mandatory depositing of your scientific output in the HAL Open Archive, it is strongly advised to create an Idhal account associated with your ORCID number to make the most of your digital identity.
