RowFold vs other tools — Where the model stops being a table and starts being a graph. (5)

• Formatted identifiers — SO-2026-0042 — with per-category sequences. RowFold: yes, several sequences per field, resets, allocate on a state change. Airtable: autonumber, or a formula you assemble. Smartsheet: prefix + date tokens, one column per sheet. Notion: prefix only, no date or padding. monday.com: prefix, but renumbers when a row moves. • Units of measure — values that convert, and refuse to convert across kinds. RowFold: yes, workspace unit library, stored canonically. Airtable: no. Smartsheet: no. Notion: no. monday.com: no. • Relationships that carry a validity period, so an ended link stops counting. RowFold: yes, dated links, overlaps refused by default. Airtable: no. Smartsheet: no. Notion: no. monday.com: no. Documents • A document on the record itself — headings, tables, checklists, images. RowFold: a field type, so a table can carry several. Airtable: rich text in a long text field, no tables or images. Smartsheet: attachments and comments. Notion: yes, the item's own page. monday.com: yes, a doc column.
