Dietary Fiber Ontology Working Group: Approved Terms (10/8/24)

[NutrientInstitute]

Fiber terms reviewed and approved by the Dietary Fiber Ontology Working Group, will now be submitted here in small batches of 5-10 terms every week or so.

The following terms have been approved by the working group and are ready for implementation into CDNO.

[LilyAndres]

Thanks @NutrientInstitute I am working on this. Question, do I need to create any sugar derivatives from this?

[NutrientInstitute]

@LilyAndres We do not have any "derives from" relationships to share at this time. We are currently fouced on direct parent-child relationships, but will pass on any feedback we may recieve on the derivation of fiber terms.

[LilyAndres]

Ok @NutrientInstitute thanks. I have added the new terms, I didn't add 'chitosan' because it already exist [CHEBI_16261] and [CDNO_0200719].

[LilyAndres]

This issue has been solved in the latest release, I will close it now.
