Preservation methodpreservation_storage.preservation_methodfile_copy (string enum) The method by which a biomaterial was preserved through the use of chemicals, cold, or other means to prevent or retard biological or physical deterioration. Should be one of: "cryopreservation in liquid nitrogen (dead tissue)", "cryopreservation in dry ice (dead tissue)", "cryopreservation of live cells in liquid nitrogen", "cryopreservation, other", "formalin fixed, unbuffered", "formalin fixed, buffered", "formalin fixed and paraffin embedded", "hypothermic preservation media at 2-8C" or "fresh".
Storage methodpreservation_storage.storage_methodfile_copy (string enum) The method by which a biomaterial was stored after preservation or before another protocol was used. Should be one of: "ambient temperature", "cut slide", "fresh", "frozen at -70C", "frozen at -80C", "frozen at -150C", "frozen in liquid nitrogen", "frozen in vapor phase", "paraffin block", "RNAlater at 4C", "RNAlater at 25C" or "RNAlater at -20C".
Storage timepreservation_storage.storage_timefile_copy (number) Length of time the biomaterial was stored for in Storage time units. For example "5".
Preservation and storage>Storage time unit (time_unit_ontology object) The unit in which Storage time is expressed.
Time unit ontology IDpreservation_storage.storage_time_unit.ontologyfile_copy (string from time_unit_ontology) An ontology term identifier in the form prefix:accession. For example "UO:0000010" or "UO:0000034".Graph restriction: Subclasses of UO:0000003, UO:0000149 from obo:efo or obo:uo.
Time unit ontology labelpreservation_storage.storage_time_unit.ontology_labelfile_copy (string from time_unit_ontology) The preferred label for the ontology term referred to in the ontology field. This may differ from the user-supplied value in the text field. For example "second" or "week".
Time unitRequiredpreservation_storage.storage_time_unit.textfile_copy (string from time_unit_ontology) The name of a time unit being used. For example "second" or "week".
