Reason for Singular versus Plural seems wrong
Great guidelines for REST here. I had one critique for those interested.
The reason given for the "Singular versus Plural" resource naming case doesn't feel like it justifies doing one over the other. https://github.com/plone/plone.restapi/blob/b51b2e97235b1a03a3bc21a93fc62d0ae638b4a2/docs/source/conventions.md?plain=1#L71-L73
Rather, it sounds like a great reason to favor consistency.
That aside, I do think it is unreasonable to impose an opinion on this matter. Many people prefer the plural for describing a collection of things. However, modern OO class naming convention would very much encourage you to use the singular form, though many instances of a class can exist. A similar conversation can be had over database table names in a relational database.
I don't think there is an answer, I think consistency is key. Therefore, I think the rule here should not be "Singular versus Plural", but rather to be one or the other wholeheartedly. And I do believe that consistency should bleed into the codebase naming conventions as well.
Just food for thought.
@aaiezza not sure I fully understand what you suggest here. I agree, there is no right or wrong on this topic. We made a decision for plural for consistency reasons. Are you suggesting that we change the headline to "Use Plural for resource naming" to make this decision more obvious?
@tisto that might be helpful for the sake of driving home the consistency idea in this document.
However, I could see a note being present with this list of conventions reminding viewers that these are Plone's decisions, not necessarily something that would work everywhere or should be adopted as-is by everyone. I see people referencing this doc https://6.docs.plone.org/plone.restapi/docs/source/conventions.html as the end-all, be-all of REST conventions that everyone should do.
