Limits and pitfalls

• No API and no documented limit. We read the 261 pages once a week, three at a time with a pause; a page came back in 0.2 s. tested
• Our index is cached on the CDN for an hour (s-maxage=3600); the state is that of the latest Monday harvest. tested
• The blocks appear in a different order per page: look them up by title (itemTitleAlt), not by position. The number in the Overeenkomst block is not a year ('40' for an agreement until 2040): read the date from the sentence. tested
• Do not copy names, phone numbers or email addresses of staff; those are on the pages too. experience
• Municipality and province are not on the page. We look up postcode and house number in the PDOK BAG WFS and place the point in the municipal boundaries (2025 division); for one location that failed (folder 'Onbekend', 16 Oct 2026). tested
• Our index only gives key and title per location; capacity, type and address are on our dataset page per location. tested
