    - Example & validation. Can we configure things so that 27% & 27 % & 0.27 will
      validate?
    - I think it's weird the way GSC writes the title. I recommend this change. Thoughts?
      I would argue this isn't an extreme unusual property. It's just a biogeochemical
      measurement.
    - This is no longer matching the listed IRI from GSC. When NMDC has its own slots,
      map this to the MIxS slot
    - Example & validation. Can we make rules that 27% & 27 % & 0.27 will validate?
    - I think it's weird the way GSC writes the title. I recommend this change. Thoughts?
      I would argue this isn't an extreme unusual property. It's just a biogeochemical
      measurement.
    notes:
    - Aluminum saturation is the percentage of the CEC occupies by aluminum. Like
      all cations, aluminum held by the cation exchange complex is in equilibrium
      with aluminum in the soil solution.

    comments:
    - The abiotic factors play a profound role on the type and composition of organisms
      in a given environment. The GOLD Ecosystem at the top of the five-level classification
      system is aimed at capturing the broader environment from which an organism
      or environmental sample is collected. The three broad groups under Ecosystem
      are Environmental, Host-associated, and Engineered. They represent samples collected
      from a natural environment or from another organism or from engineered environments
      like bioreactors respectively.

      Ecosystem categories for Host-associated samples can be individual hosts or
      phyla and for engineered samples it may be manipulated environments like bioreactors,
      solid waste etc.

      air as different Ecosystem Types. In the case of Host-associated samples, ecosystem
      type can represent Respiratory system, Digestive system, Roots etc.

      I would argue this isn't an extreme unusual property. It's just a biogeochemical

    - This is no longer matching the listed IRI from GSC. When NMDC has its own slots,

    - Aluminum saturation is the percentage of the CEC occupies by aluminum. Like

    comments:
    - The abiotic factors play a profound role on the type and composition of organisms
      in a given environment. The GOLD Ecosystem at the top of the five-level classification
      system is aimed at capturing the broader environment from which an organism
      or environmental sample is collected. The three broad groups under Ecosystem
      are Environmental, Host-associated, and Engineered. They represent samples collected
      from a natural environment or from another organism or from engineered environments
      like bioreactors respectively.

    - The Environmental ecosystem (for example) is divided into Air, Aquatic and Terrestrial.
      Ecosystem categories for Host-associated samples can be individual hosts or
      phyla and for engineered samples it may be manipulated environments like bioreactors,
      solid waste etc.

    - The Aquatic ecosystem category (for example) may have ecosystem types like Marine

      air as different Ecosystem Types. In the case of Host-associated samples, ecosystem
      type can represent Respiratory system, Digestive system, Roots etc.

    - All elevations must be reported in meters. Provide the numerical portion only.
    - Please use https://www.advancedconverter.com/map-tools/find-altitude-by-coordinates,

      I would argue this isn't an extreme unusual property. It's just a biogeochemical
      measurement.
    - This is no longer matching the listed IRI from GSC. When NMDC has its own slots,

    - Aluminum saturation is the percentage of the CEC occupies by aluminum. Like
      all cations, aluminum held by the cation exchange complex is in equilibrium

    comments:
    - The abiotic factors play a profound role on the type and composition of organisms
      in a given environment. The GOLD Ecosystem at the top of the five-level classification
      system is aimed at capturing the broader environment from which an organism
      or environmental sample is collected. The three broad groups under Ecosystem
      are Environmental, Host-associated, and Engineered. They represent samples collected
      from a natural environment or from another organism or from engineered environments
      like bioreactors respectively.

      used in other samples?

    comments:
    - Identifiers must be prefixed. Possible FAIR prefixes are IGSNs (http://www.geosamples.org/getigsn),
      NCBI biosample accession numbers, ARK identifiers (https://arks.org/). These
      IDs enable linking to derived analytes and subsamples. If you have not assigned
      FAIR identifiers to your samples, you can generate UUIDs (https://www.uuidgenerator.net/).
