dataportalen

Python access to dataportal.se that gives you plain dicts, not RDF.

Sweden's open-data registry describes its 23,500 datasets in RDF, which means every value arrives as a web address: a dataset about roads is filed under http://publications.europa.eu/resource/authority/data-theme/TRAN rather than under "transport". Working out that it means "transport" is, per the registry's own documentation, your problem.

This package makes it not your problem. You search with words and you get dictionaries back.

Install

pip install dataportalen

Distribution and import name are both dataportalen. The unrelated dataportal package on PyPI is a Korean public-data client — not this.

Quick start

from dataportalen import Catalog, text

cat = Catalog()          # downloads the catalogue the first time: ~7 min, 64 MB
print(cat.info())        # {'datasets': 23576, 'data_services': 599, ...}

page = cat.datasets(theme="transport", format="csv")
print(page.total)                               # 67

for dataset in page:
    print(text(dataset["title"]), text(dataset["publisher"]["name"]))
    for dist in dataset["distributions"]:
        print("   ", dist["format"], dist["access_url"])

That first line takes about seven minutes. It downloads the whole catalogue once, and every search after that is local and takes hundredths of a second. Run it deliberately the first time — it prints a progress line.
