Physio-chemical properties human readable defs etc? #72

Open meganrwong opened 1 year ago

meganrwong commented 1 year ago

Hello, We are looking at re-use potential of your physio-chemical properties list. Do I have the URI for physio-chemical properties right? For example http://w3id.org/glosis/model/layerhorizon#Aciexc

I was hopeful I would land at a point with human readable definition of e.g. of exchangeable acidity (Aciexc), and also wondered the source of the code list (was it FAO? might you have a source reference you can point us to?).

Hi Megan,

the physio-chemical properties are encapsulated by the container class glosis_cl:PhysioChemicalPropertyCode within the code-lists module. The full list of individuals is in the lines below, linked also with SKOS predicates.

This list stems from a document titled "Specifications for the Tier 1 and Tier 2 soil profile databases of the Global Soil Information System" produced with Pillar 4 of the Global Soil Partnership in 2018. To my knowledge that document was never made public. There is a number of questions around these properties, especially whether they actually comply with the Property concept of SOSA, as they carry some information on the observation procedure. These questions will be addressed for release 2.0 of the ontology.

In release 2.0 I also hope to have better human readable descriptions and associated references, as in the procedures module.

Hello Luis. Thanks for the clarification. We will be interested in work plans for developing obsv properties lists for soil, as we are in need of a better, good quality list also (ANSIS and Soil VAS Soil CRC). Ideally we would not duplicate efforts of a list that should be re-usable between many. By the way I notice ENVO and AGRO are getting some up also.

Hi Megan,

plans exist, but not a time-line yet. In any case, @Montanaz0r has been working on a tool that transforms CSV files into RDF (and back). The expectation is for this tool to help engaging with soil scientists in the development of code-lists (properties and so on).

Do you have any idea where I may be able to find this document so that I can cite it as the source of this list? Much thanks for your time.

Hi again Megan. This thread ended up triggering the publication of the ISRIC report that provided the basis for the current list of physio-chemical properties: https://doi.org/10.17027/isric-dcmkd4-g431

Descriptive (qualitative) properties and respective code-lists were digitised from the FAO Guidelines for Soil Description. That work was conducted by Kathi Schleidt and Thomas Reznik, and also resulted in a report delivered to the GSP. The GSP is yet to make it public.
