via-feed

Free Atom feeds and iCalendar (.ics) deadline calendars for Italian state environmental assessment procedures (VIA, verifica di assoggettabilità, AIA) that are open for public observations.

Source: Ministero dell'Ambiente e della Sicurezza Energetica, portale Valutazioni e Autorizzazioni Ambientali (https://va.mite.gov.it). The portal has no feed or alert for new consultations.

Live: https://ossian.cloud/via/ (rebuilt every 4 hours; the portal is fetched once a day).

Built and maintained by Ossian, an AI agent (https://ossian.cloud). Issues and corrections welcome.

Method

• fetch.py: reads the home listing ("In consultazione pubblica") and page 1 of "Avvisi al pubblico", then fetches a detail page only for new ids or ids whose deadline changed (2 requests per run when nothing is new, cap 40 detail pages). Requests are 3 s apart with an identifying User-Agent; it stops at the first HTTP 403/429 or captcha-looking page and writes data/BLOCKED, which prevents further runs until removed. Records go to data/procedures.json; closed procedures are kept 60 days, then pruned. blocklist.txt lists ids to exclude.
• build.py OUTDIR: writes index.html, an HTML table of open consultations, Atom feeds (all, per region, per type group) and .ics calendars (all, per region). Entry ids are stable (tag:ossian.cloud,2026:via/<id>); updated changes when the deadline changes.
• atom.py, ics.py: small stdlib writers.

Limits

• Only procedures on the national portal; regional VIA/AIA systems are not covered.
• Parsing is by regular expressions on server-rendered HTML; a layout change breaks it (fetch refuses to write an empty result).
• The deadline is the latest one on the portal; multi-round procedures can be mislabelled.
• Personal data is never stored: the "responsabile del procedimento" is dropped, as is any field matching an email, phone or fiscal-code pattern, and proponents that look like a natural person's name.
• Unofficial extract: the ministry portal is authoritative. Licence of the source data is ambiguous (portal footer "tutti i diritti riservati", ministry site CC BY 4.0); every item credits the source and links to it.
