Make a PortalJS portal harvestable by national/EU/US open-data portals — emit standards-compliant DCAT catalog feeds (DCAT 2/3, DCAT-AP, DCAT-US, national profiles) in JSON-LD, Turtle, and RDF/XML at build, with autodiscovery and per-profile conformance checking. Use when a portal needs to be harvested by data.europa.eu, data.gov, or a national open-data catalog.

# PortalJS — Add DCAT
## Overview
Turn an existing PortalJS (`portaljs-catalog`) portal into a harvestable data catalog.
PortalJS is Frictionless-native — a dataset is a Data Package (see
`portaljs-define-schema`) — and DCAT is the serialization + harvest layer on top
(`lib/metadata/dcat.ts` + `lib/metadata/dcat-profiles.ts`). This skill selects one or
more DCAT application profiles, maps every dataset's metadata to them, and writes
static feed files at build time — JSON-LD, Turtle, and RDF/XML — so external catalogs
(data.europa.eu, data.gov, national portals) can harvest the datasets automatically,
on any static host, with no runtime.
