I don't understand. How would you use LibreOffice to build a collection of object photos and descriptions, with custom descriptors and normalized data references, that could be deployed as a searchable / filterable website?
What I'm describing, and what the article suggests, isn't about a UI for creating key-value stores that can be saved as CSVs. Any database UI wrapper can do that. The concept is about ingesting CSVs, normalizing the data, and turning them into websites. The parent I was responding to built a system (or two systems, apparently) for doing this as SaaS based around Wordpress.
