GeochemAnalyticalMethod: inconsistent notation formats

[mk618]

We have a notation “ICPMS” but then another one as “MC-ICP-MS”. Should the first also read “ICP-MS”?

[mk618]

There is also "LAICPMS". Better as "LA-ICP-MS"?

A few comments from me after looking into the GEOROC mapping of methods:

• Hyphens are not always used systematically in the methods. Perhaps this could be made more systematic in the future, so that the individual method “parts” (e.g. MC-ICP-MS or Q-ICP-MS but LAICPMS or SNICPMS) are always separated by a hyphen, or that there are no hyphens at all?

• Gamma Counting and Gas Chromatography analysis have the same abbreviation "GC". My suggestion would be to change the abbreviation for gamma counting to "GAMMA", then it would also fit systematically with Alpha Counting ("ALPHA") and Beta Counting ("BETA"). The problem is that the abbreviation "GAMMA" is already used for Gamma Ray Spectrometry, where the abbreviation could then also be changed (e.g. "GRS" or similar).

• For Inductively Coupled Plasma Emission Spectrometry, the current notation is "ICPES", which actually also fits. In common usage, however, the abbreviation for this method is "ICPAES" (Inductively Coupled Plasma Atomic Emission Spectrometry; if I’ve understood it correctly), so would it make sense to use this common abbreviation here? Or should the Inductively Coupled Plasma Atomic Emission Spectrometry (ICPAES) be an extra method derived from ICPES, as is the case for ICPOES?

• Secondary Ionization Mass Spectrometry has an abbreviations "TOF-SIMS" in the RVA version, but should be only "SIMS"?

• There is currently no method for "SHRIMP" on the RVA version of the methods. The GEOROC SHRIMP methods were mapped to SIMS (which is certainly not wrong), but in my opinion "SHRIMP" could also be used as its own method.

• In GEOROC, we also have the multi-collector SIMS (MC-SIMS) and TIMS (MC-TIMS) methods, which would now also be lost through the mapping (to SIMS and TIMS). I could also see an advantage in keeping the MC variants in the methods (even though the analytical instruments are same as for non-MC methods).

• Should High Resolution Inductively Coupled Plasma Mass Spectrometry be a separate method? This only describes the aperture of the entrance slit in the device is, whereby this is not specific to the device or method type.

• In certain combinations for ICPMS, important information is lost, e.g. Laser Ablation Multi-Collector Inductively Coupled Plasma Mass Spectrometry is mapped to LAICPMS, whereby the "multi-collector" part is then completely lost. Although, MC-ICPMS is also a recognized method and a combination of LA and MC would be very useful here in my opinion. Similar cases also occur with other features, such as Isotope Dilution (rather important information for precise isotopic data), Sector-Field, Quadrupole, etc., where the "Laser Ablation" feature predominates and is favored as a method for mapping. Is there a good solution for this?

Meeting 2024-02-22 Add SHRIMP as a method Technique -- one process method-- workflow

Mapping spreadsheet-- move to github hyphenate notations narrower notations in alt labels alt (non-hyphyenated notations) in altLabel.

he problem is that the abbreviation "GAMMA" is already used for Gamma Ray Spectrometry, where the abbreviation could then also be changed (e.g. "GRS" or similar). "ICPES", which actually also fits. In common usage, however, the abbreviation for this method is "ICPAES" change ICPES to ..AES, ..ES is alt label.

SIMS (MC-SIMS) and TIMS (MC-TIMS) methods add as altLabels add ID- and MC- altLabels.

regarding technique vs method vs procedure etc: should the definition of Analytical Method (https://w3id.org/geochem/1.0/analyticalmethod/analyticalmethod) be updated?

[smrgeoinfo]

currently we have

Procedures that operate on material samples to produce observation results with information about the physical properties, chemical or isotopic composition, crystallography, or molecular structure of the sample. {@en}

We could add a scope note along the lines of A method is often a composite of multiple processes that might involve one or more instruments and techniques.

The various combinations of laser ablation, multi-collector, and ICPMS are mostly covered by the skos:altLabels. Following our discussion in the meeting today, I think we're in agreement that we need to keep the size of the vocabulary under control, and make it clear in instructions that in these cases, the most specific subsuming class should be used for data construction, and users should be aware that if they use very detailed methods in their search they might miss results of interest because all the details of the method might not be included in the class definition. Free text in the metadata should include as detailed as possible description of the method, with the lab's favorite naming for the methods; these can be indexed for search.
