PortalJS — Add Resource

Overview

Add a resource — an additional file — to a dataset that already exists in a portaljs-catalog portal. Where /portaljs-add-dataset creates a new dataset (one file), this skill adds a file to an existing one: a data dictionary, a methodology document, or another data file (e.g. a second year's figures).

Mirrors the Frictionless Data Package model: a dataset holds a resources[] array, and the showcase at /@<namespace>/<slug> renders one section per resource (preview, schema, download). A single-file dataset migrates to resources[] automatically the first time a second file is added — no data is lost.
