Slot: sample collection duration (sample_collection_duration)

The length of time over which the sample was collected. A grab sample is collected at one moment and a composite sample accumulates over a period (commonly 24 hours).

URI: nmdc:sample_collection_duration

Applicable Classes

Name Description Modifies Slot
Biosample Biological source material which can be characterized by an experiment. no

Properties

Examples

A 24-hour composite sample; the raw value keeps the weighting detail the submitter reported.

type: "nmdc:QuantityValue"
has_raw_value: "24-hr flow-weighted composite"
has_numeric_value: 24
has_unit: "h"

Comments

  • Record the duration in hours, minutes or days and keep the submitter wording in has_raw_value. Whether a composite was flow-weighted or time-weighted belongs in samp_collec_device and samp_collec_method, not here.

notes:
- 'PHA4GE Wastewater Contextual Data Specification 4.4.4: related match to sample
  collection time duration value (GENEPIO:0100766) and sample collection duration
  unit (GENEPIO:0100767); one QuantityValue here is split across PHA4GE value and
  unit fields.'
- 'NCBI BioSample: close match to the sample_collection_time_duration attribute of
  the PHA4GE.wwsurv.1.0 package (an ISO 8601 duration) and to the ww_sample_duration
  attribute of the SARS-CoV-2.wwsurv.1.0 package (whole hours, 0 for a grab sample).'
comments:
- Record the duration in hours, minutes or days and keep the submitter wording in
  has_raw_value. Whether a composite was flow-weighted or time-weighted belongs in
