Applicable "stated in" value

ChEBI (Q902623), Chemical Entities of Biological Interest (Q55118295)

Data type

External identifier

Template parameter

Template:Infobox drug (Q6033882) ChEBI , Template:Chembox (Q52426) ChEBI

Domain

term (note: this should be moved to the property statements)

Allowed values

\d+ (Only digits, without the prefix "CHEBI:")

Usage notes

Only primary CHEBI identifiers (from "CHEBI ID" field) should be present in items; secondary identifiers (from "Secondary ChEBI IDs" field) should not be added.

Example

dimethyltryptamine (Q407217) → 28969 (RDF)
acetylene (Q133145) → 27518 (RDF)

Canonical capitalization and OBO prefix[edit]

Although CHEBI frequently uses a lowercase h it is more common to use a fully capitalized prefix 'CHEBI' when constructing database identifiers. For example:

GO prefix registry
OBO Entry - the OBO purls are of the form $OBO/CHEBI_nnn, and rendered as CURIEs CHEBI:nnnnn

Is there a way we can denote this as a property here so that we can harmonize our registries?

I think there is no real problem as Wikidata does not store or construct a full identifier like CHEBI:12244 but only the number part. You cannot construct the id by using the property label since that is language-dependent. --SCIdude (talk) 15:59, 4 April 2021 (UTC)[reply]

Name of property is gone?![edit]

Tried to add a ChEBI ID for a compound I added to Wikidata (https://www.wikidata.org/wiki/Q2756638). Unfortunately, I could not search ChEBI as an identifier... After checking another compound; I saw the name of the property was not displayed, it just reads P683. Why is this? @Egon_Willighagen: @andrawaag:

I guess this was a temporary hickup. If you still have the issue, ping me with a screenshot. --Egon Willighagen (talk) 06:14, 1 January 2021 (UTC)[reply]

Secondary identifiers[edit]

There is a problem with current constraint and the presence of secondary identifiers. One way is to delete secondary ids, the other way is to change the constraint. You can comment on this topic here (WikiProject Chemistry). Wostr (talk) 18:59, 14 July 2018 (UTC)[reply]

@Wostr: I have added a Modified single value constraint on the top of this page that does not have these shortcomings. I propose to use that and remove the general single value constraint. --SCIdude (talk) 15:42, 4 April 2021 (UTC)[reply]

@SCIdude: I think the result of the discussion on WikiProject discussion page was that there should be only one ChEBI ID per item and we should not store secondary IDs. Wostr (talk) 19:11, 4 April 2021 (UTC)[reply]

skos:exactMatch?[edit]

How am I supposed to use the constraint? And what is the purpose? For example, carbon dioxide (Q1997) uses skos:exactMatch (exact match (Q39893449)) but this results in conflicting properties: how is the relation between Wikipedia and Wikidata defined? While it attempts to introduce semantic meaning, it does it wrongly. The ontological model in ChEBI is not skos:exactMatch of what Wikidata uses:

ChEBI has every chemical as a subclass not an instance
things like gas are not associated with the chemical compound (ChEBI does not have a CO2 for gas and one for the solid; ChEBI goes wrong here itself)
Wikipedia often is about slightly different things (this is a larger problem, I know)
things like refrigerant (Q266790) are roles in ChEBI, not types

So, should I convert this to skos:closeMatch (close match (Q39893184))?

Second, is this also how we are going to link Wikidata neutral forms of compounds to the corresponding ions in ChEBI, e.g. with related match (related match (Q39894604))? --Egon Willighagen

This is most useful for MeSH IDs, because in case of that database, there are many situations of not 1:1 relationships between entries. In case of ChEBI I started adding these in items about classes and groups of chemical compounds to indicate whether item in WD is an equivalent to ChEBI entry (and maybe in the future that would allow to check our classification tree and ChEBI). In case of chemical compound, I think most of WD items should have an exactMatch. About the problems mentioned: (1) WD should have every chemical compound to be a subclass, (2) instance of gas was an incorrect statement that was imported from ru.wiki, (3) Wikipedia is not a problem to anything in WD, it does not define an item, it does not affect any statements in an item; Wikipedia sitelink should be associated with the most similar concept in WD (ideally it should be a 1:1 relationship, but in the case of chemistry, usually it is not 1:1), (4) I think all statements involving roles and uses should be moved to more specific properties like has use (P366) and subject has role (P2868); just like CO2 is not a preservative, it is used as preservative, it is not a vasodilator agent, it acts as vasodilator agent. I tried to do this with food additives, but we need a more general approach to this preceded by a discussion, (5) neutral forms should be linked to neutral forms, ions should be linked to ions; relations other than exactMatch should be used only when there is no an exactMatch item.

@Egon Willighagen: Wostr has correctly removed instance-of gas. The irritation comes from "greenhouse gas". As to "ChEBI has every chemical as a subclass" I think we are coming to this conclusion in Wikidata too. --SCIdude (talk) 15:54, 4 April 2021 (UTC)[reply]

Also, don't use ChEBI Id to connect organic ion with base, use conjugate acid (P4147) and conjugate base (P4149). However for anorganic ions skos:related is certainly fine as long as there is no WD property. --SCIdude (talk) 16:03, 4 April 2021 (UTC)[reply]
