iarcratingid

iarcratingid is a term used to describe a persistent, internal identifier applied to a specific rating decision within systems that track carcinogenicity assessments, particularly those associated with the International Agency for Research on Cancer (IARC). In public data releases or documentation, it may appear as a reference key that uniquely links a rating entry to its broader metadata, such as the evaluated agent, the rating category, the publication or monograph in which the rating appears, and the date of assessment.

The primary function of an iarcratingid is to enable precise reference and data linking. By assigning a stable identifier to a discrete rating, researchers, publishers, and data repositories can retrieve the exact entry, compare revisions, and integrate the rating with related records across databases. This facilitates reproducibility, version control, and traceability of the assessment process.

Format and scope may vary by implementation, but an iarcratingid is typically an alphanumeric string generated at the time of rating. It may encode or accompany components such as the agent or substance code, year of rating, and a sequence or version number. The exact syntax is governed by the data schema used in a given IARC data release or internal system.

In practice, iarcratingid supports programmatic access to IARC information and archival of historical assessments. When a rating is updated or superseded, the original identifier may remain for historical reference, with the updated entry receiving its own identifier to reflect the change.
