-======Recommendation to ...======
-M4.3 Researchers assign IGSNs to samples
 =====Description=====
-Status:
+Status: 23.5.2025
 =====Motivation for this Recommendation: =====
-[shortened from below]
+Researchers, technicians, and others who take or handle samples are best positioned to record IGSNs because they are directly involved in the sampling process and have immediate access to critical contextual information. By recording IGSNs at the time of sampling—and documenting parent IGSNs when creating subsamples—they help ensure that sample provenance is accurately captured and preserved. This reduces the risk of information loss, supports reproducibility, and enables reliable linking of samples to data, publications, and other research outputs. Their active involvement in IGSN registration strengthens the traceability and long-term value of sample-based research.
 =====Recommendation ====
-[shortened from below]
+It is recommended that researchers, technicians, and other people who take samples:
-[Format: Wer! macht was! wo! wann! unter welchen Voraussetzungen!]
- For researchers it means:
-    Record an IGSN with any sample taken.
-    Record the parent IGSN with any subsample measured
-For data infrastructures:
-    record a IGSN to identify samples and parent samples and make this data part of the metadata available for harvesting.
+  - record an IGSN when taking a sample.
-    treat IGSN metadata as the primary source of truth and update your own metadata accordingly.
+  - record parent IGSNs when subsampling or splitting physical samples.
