Add a chart (line, bar, area, pie, or scatter) to a dataset's showcase in a PortalJS portal.

Add a dataset (CSV, TSV, JSON, or GeoJSON) to an existing PortalJS portal.

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.

Render a GeoJSON dataset on an interactive Leaflet map in the Views section of a dataset's showcase.

Add another file (resource) to an EXISTING dataset in a PortalJS portal — a data dictionary, methodology, or an additional data file.

Recommend a data-portal architecture (storage, compute, catalog, access, hosting, metadata) from your needs, then hand off to the build skills.

Audit a local or remote tabular file (CSV/TSV) for common data quality issues.

Wire a scaffolded PortalJS portal to a CKAN backend over its API.

Define a dataset's metadata profile — infer a Frictionless Table Schema from its data, add Data Package metadata (license, sources, keywords), and write it into datasets.

Deploy a PortalJS portal to PortalJS Arc — Datopian-managed static hosting on Cloudflare.

Migrate (harvest) datasets between open-data platforms.

Scaffold a new PortalJS data portal from a brief.
