Agree with the idea of clustering the requirements. At present, there is no ordering or group at all ... I'm just adding them as they materialise & trying to reference the motivating use cases.

I've added the clustering comment as an issue in the doc to remind us to group things as we progress.

Hi Jeremy,

Thanks for all your work pulling together the use cases and requirements.

Do you think it would be useful to cluster the requirements? Looking at them, I can see:

  * Parsing, eg requirements around recognising other delimiters
  * Annotation Types, eg R-PrimaryKey
  * Metadata Discovery, eg R-PackagingOfMultipleTables
  * Applications, eg R-CsvValidation
  * Non-Functional, eg R-ZeroEditCompatibility

Regarding the requirement R-PackagingOfMultipleTables, I think the requirement is to annotate a group of tables, not necessarily to package them. In other words, a design in which there was a metadata file that pointed to a group of tables hosted elsewhere on the web would seem to satisfy the requirement from PublicationOfNationalStatistics: they wouldn’t necessarily need to be packaged together (eg in a zip).

Also, FWIW, I would only take syntactic requirements from published “CSVs”, not from non-text-based formats like Excel. So, for example, I wouldn’t use the ONS Excel files as demonstrating a requirement to have multiple tables within a single CSV file.
