Suggested parent term

Parent CDNO 'dietary nutritional component'

We'll make it be subclass to 'plant matter' [ENVO:01001121]. With an axiom linking to 'dry' [PATO:0001824]

Following an example such as https://github.com/FoodOntology/foodon/releases/tag/v0.4.8 follow the github release process and give a little description nothing to fancy just a small paragraph about CNDO and what it includes. ie. DNCs and chemical concentrations.

You can look at this envo release https://github.com/EnvironmentOntology/envo/releases/tag/v2020-06-10 for an example of how to name it. something like 2020-06-10 release

Following up on some discussion with @LilyAndres we have an opportunity for some potential interest and maybe adoption of CDNO by some of our collaborators. In our next release we'll need to make sure that we clarify that we've changed the axioms on original set of terms away form plant and to material to be more general. Normally this would merit deprecation and replacement, however, since our initial release 2021-02-08 was experimental and we did not yet have a user-base, we opted to simply change the axioms within the chemical concentration's while keeping the IDs the same. In our next release we'll need to make sure that's clear.

This issue has been created to discuss the relationships of vitamins and their vitamers in CDNO and CHEBI.

1. We have ask CHEBI team, specially @amalik01 for clarification about the relationships described in CHEBI. One issue raised is the different relationships assigned to fat and water soluble vitamins. For example:

• The ‘B vitamin’ [CHEBI:75769] and ‘Vitamin C’ [CHEBI:21241] have the ‘is_a’ relationship with ‘water-soluble vitamin’ [CHEBI:27314].

• In contrast ‘Vitamin A’ [CHEBI:12777], ‘Vitamin D’ [CHEBI:27300], ‘vitamin E’ [CHEBI:33234] and ‘Vitamin K’ [CHEBI:28384] have the ‘has_role’ relationship with ‘fat-soluble vitamin’ [CHEBI:24020].

The term vitamer is not defined as such in CHEBI. However, some vitamer molecules have been assigned to specific vitamins with:

• ‘has_role’ = eg some vitamers from ‘B vitamin’ [CHEBI:75769] and ‘vitamin C’ [CHEBI:21241]

and the rest with

• ‘is_a’

See the following link:

The proposal from CHEBI is to

• assign 'is a' vitamin to both fat and water soluble vitamin

• assign the 'has role' relationship to all vitamers (in their case vitamin) molecules.

2. Within CDNO we propose to refine/extend the relationships, re-using where possible the CHEBI definitions.
Thus: (reading the relationships right to left)

3. We propose establishing definitions/relationships for vitamin roles within the ‘dietary_function’ class of CDNO.

A separate thread/issue will be generated to discuss this class.

What do you think?

We'll need to choose and add an appropriate license.

I was expecting that when we ran make prepare release that it would call a robot reasoning routine on the cdno.owl file and have a clean concentration hierarchy, akin to running elk locally in the ontology. However, it did not. looking more into it other ontologies such as ENVO have the same workflow and don't seem to have ELK run to make a nicer hierarchy. There is probably a way to fix this using robot's reason command.

Suggested parent term

Parent CDNO 'dietary nutritional component'

As the coverage of CDNO is now "Compositional Dietary Nutrition Ontology" I would suggest to clarify the current hierarchy which is "dietary nutritional component"

Actually, they are a mismatch between compositional constituents and "real" nutritional components.

I mean we can enlarge the coverage of this branch by renaming it "compositional constituent" and then distinguish between nutrient subclasses and other subclasses (see my suggestion below)

This is the direction I am taking in my own work. I would be happy if we could agree on this.

Note about the definitions in the concentration terms, the grammer is a little off it's

The concentration of X when measured in plant structure.

It should be something like a plant structure. or some plant structure. @CropStoreDb and @LilyAndres any preferences? I think some works. I'll add this to the DOSDP file before we run all the new terms.

@LilyAndres what's the plan are you going to run the whole workflow soon? If so I we should quickly address this.

CDNO is currently focused on 'concentration of' chemicals in 'plant structure'. The FoodOn ontology curation team is looking at concentrations of chemicals in animal and plant materials - including mercury in fish for example. One move would be to generalize all the CDNO concentration expressions to apply to 'organism' instead of just 'plant structure'? What are your thoughts on that?

Assuming CDNO could take on more general organism related concentrations, we'd then be in a position to contribute them. For example, there is a variation on your mercury concentration (probably not a subclass though) which is concentration of 'methylmercury compound' in organism, which I guess is the form commonly quantified in food.

We have a google sheet where we are working on the precomposed terms and patterns for high concentration of X in Y, and as well food classes having high (or low) concentrations.

@LilyAndres @CropStoreDb @ddooley @ramonawalls

Regarding the CDNO mappings, I realize it might not quite show up how you’d want/expect. In the robot template it makes sense as USDA and INFOODS are in the column headers.

However, those won’t get compiled so what will end up happening is we’ll get

Perhaps this is desired and we can stop there, however, if not I propose two possible solutions:

1. Change the annotation property from http://www.geneontology.org/formats/oboInOwl#hasDbXref to a newly invented one in CDNO perhaps something like http://www.geneontology.org/formats/oboInOwl#USDADbXref

2. Add something like USDA_ to the beginning of all the rows in the mappings csv and keep the hasDbXref annotation property.

That way it'll show up looking something like this:

I'd advocate for solution 2 but would like to hear everyone's thoughts/ suggestions.

We'll leverage the ENVO chemical_concentration DOSDP for our new CDNO concentration terms. See ENVO's chemical_concentration.csv, and chemical_concentration.yaml.

This issue has been created to discuss the labels and reuse of CHEBI terms in the CDNO mineral nutrient class.

Having checked some CHEBI labels that were incorrectly re-labeled in CDNO (see issue #64), e.g. re-labeled as 'calcium', we identified some terms where the representation of mineral nutrients could be improved in the dietary nutrition domain:

1. We propose the reuse of other CHEBI terms. For example the ionic form (atom with more or less electrons) of an element is often measured when quantifying e.g. the 'concentration of calcium' in milk, typically using a method (eg ICP-MS) that estimates the concentration of calcium (2+) ions. However, the quantity being calculated is typically expressed as atomic Ca, even though it may be present in multiple bound, ionised or other molecular forms (eg salts). In some situations, there may be an assay that allows the estimation of concentration (via stoichiometry) of a specific salt.

Thus, within the 'dietary nutritional component' and 'dietary nutritional component concentration' classes, we would include eg. 'calcium(2+)' [CHEBI:29108] in addition to 'calcium atom' [CHEBI:22984].

2. To ensure there is vocabulary more tailored to dietary nutrition, we propose the adoption of the terms ‘dietary calcium’, ‘dietary magnesium’ etc, and under these have options for hierarchical sets of terms including: ‘calcium atom’, ‘calcium ion’, ‘calcium salt’.

We welcome feedback to know whether this provides a way forward to help nutritionists navigate to appropriate ChEBI terms and distinguish in what form an element may be present, quantified/estimated or reported depending on assay.

3. The hierarchical classification would look something like this, using 'calcium' as an example:

Hey @LilyAndres, we'll need to add some descriptive information to our README.md. Definitely the title: Crop Dietary Nutrition Ontology, and any other supporting/descriptive information about the project. See ENVO's, or @ramonawalls BCO or PCO README.md files as examples.

@LilyAndres noticed the following terms are miss-matched between the modules/mappings.owl and modules/chemical_concentration.owl files.

CDNO:0200181	5-formyltetrahydrofolic acid
CDNO:0200182	vitamin B

It should be an easy fix to just switch them in the templates/mappings.csv to be in the same order as they are in the templates/chemical_concentration.csv file.

Maybe @LilyAndres can double check to see if there are any others that got switched. I suspect this happened because there was some confusion about the vit b term, but so maybe its the only one but if were not sure it's good to check.

This concentration points to CHEBI:15640 - 5-formyltetrahydrofolic acid, but it seems like the hasDbXrefs are coming in at too broad a level. Can the INFOODs and USDA_NDB tags be associated with concentrations at a more granular level? Is it really the case that multiple ones are correct for 5-formyltetrahydrofolic acid? Ideally INFOODs and USDA_NDB are only 1-1 DB Xrefs.

I am in the process of deprecating FoodOn nutrient terms in favour of the CDNO ones. On the vitamin branch I've managed to eliminate FoodOn duplicates for the most part, but there are some vitamin B & C underlings that I'm not sure about. See the bolded FoodOn vitamin branch (which uses NCIT Vitamin term http://purl.obolibrary.org/obo/NCIT_C944) which will be obsoleted soon:

I wasn't sure if the underlings given on the FoodOn side should be added to the CHEBI side? Or are they erroneous?

I wrote a python script to convert the NCF into the working Robot templates. I'll add that work to CDNO in a util directory in cdno/src/ontology.

In order to map the CDNO chemical concentration terms to existing labels or other information from the consortia such as the USDA or INFOODs, we'll need a new mapping robot template.

We'll be making use of a Robot template to generate the Nutrition Schema Framework terms. As per FOODON's example, we'll use this google sheet to collaboratively edit the Robot template, and export it as a csv file and compile within the ontology.

Following form the work in #52 we now have the issue that some classes are asserted as subclass to material entity when we only want them to show up in cdno-edit.owl as subclass to the appropriate terms from the dietary nutritional component hierarchy.

We'll need to remove the subclass axioms that are subclass to material entitiy, for example

Was there a technical/logic issue trying to position the hierarchy? I see:

As per ongoing discussions with @CropStoreDb @ramonawalls and @LilyAndres we will need to create terms for harvested materials which are the cross of NCBITaxon ids and PO plant parts. @LilyAndres has created a spreadsheet of relevant crops and their anatomical parts relevant to use-cases within the scope of CDNO here: CDNO_PO_harvested_materials. A preview of the sheet is as follows:

As we formulate an appropriate DOSDP or Robot Template, we'll want to capture the derives from relationship (or similar) between the PO and NCBITaxon terms respectively. These terms are intended to fill the part of some Y in the CDNO concentration of terms, of which the nutritional framework terms will inhere in.
