Sample repository

A repository for physical research samples — geological, environmental, biological, or material — that catalogues, stores, and provides access to samples for downstream analysis, often issuing persistent identifiers (IGSN, DataCite DOI) for citation and provenance tracking.

Answers are drawn from this dictionary entry and the rest of the CASRAI corpus, with a link to every source.

Answers are AI-generated from CASRAI’s own published pages and can be wrong, so check the linked sources before relying on one; your question is logged without personal data — never sold, never used to train a third-party model — to show us what CASRAI is missing, so please do not type personal or confidential details. How we use this

Sample repositories span domains from geosciences (SESAR, the international IGSN allocator) and oceanography (rock-core and water-sample archives) to environmental (insect and plant-specimen collections) and biomedical (biobanks, biorepositories). They differ from data repositories by managing physical artefacts: storage logistics (climate-controlled facilities, freezers), shipping, and physical-condition QA matter alongside the digital metadata layer. PID-minting at sample registration (IGSN-style) is now best practice in many sample-repository communities.
