In some sense the information in this category could be a repeat of metadata in the sampleprep category. I went back to the metadata originally in sampleprep and moved some of it here as it seemed to fit better. I also changed the name of the category to sample metadata (from matrix metadata) because the sample matrix (while important) is only one piece of metadata that describes a sample and how it was sampled. So, the metadata is broadly about the sample, how it was collected, and how it was stored. Thoughts? Email This email address is being protected from spambots.

- identifier: the unique identifier of the sample (string) [10-02-14]
- amount: the mass or volume of the sample received or collected (float/decimal) [10-02-14]
- amount unit: the unit of the quantity of the sample amount (string/enum/vocab) [10-02-14]
- aggregation: if the sample was obtained by collecting it at multiple locations and combining then it should be described here (string) [10-02-14]
- matrix: description of the type of sample material (from a controlled vocabulary) (string) [10-02-14]
- physical state: the phase of the sample (e.g. solid, liquid, gas, slurry, etc.) (enum) [10-02-14]
- homogeneity: the homogeneity of the sample at collection (e.g. homogeneous, heterogeneous, emulsion) (enum) [10-02-14]
- sampling event: was the sample collected as part of a specific trip/exploration/voyage? (string) [10-02-14]
- sampling location: a description of or GPS coordinates for where the sample was obtained (string) [10-02-14]
- sampling depth: the depth below sea level the sample was collected (string) [10-02-14]
- sampling depth unit: the unit for the sampling depth (string/enum/vocab) [03-01-15]
- sampling altitude: the altitude above sea level the sample was collected (string) [10-02-14]
- sampling altitude unit: the unit for the sampling altitude (string/enum/vocab) [03-01-15]
- sampling conditions: what were the environmental conditions (weather) where the sample was collected (string) [10-02-14]
- sampling protocol: how the sample was collected (string) [10-02-14]
- sampling equipment: the apparatus used to collect the sample (string) [10-02-14]
- field stabilization: a description of the any processes used to stabilize the sample in the field (string) [was 'field prep' 02-16-15]
- field additives: list of substances added to the sample to stabilize the concentration of the analyte(s) to be determined (string) [was 'field prep' 02-16-15]
- storage container: container that the collected is stored/placed in for transport/storage (should include material type as well as container type) (string) [02-16-15] (replaced 'vessel' with 'container')
- storage conditions: how/where the sample is stored after collection, prior to lab processing and/or analysis (string) [10-02-14]
