Not every government that publishes tenders online runs a bidding portal. Some — including a number of Canadian provincial and territorial governments and other open-data programs — publish their tenders as open-data datasets on a platform called CKAN. If you have ever browsed a site with a “data catalogue” of downloadable CSV and JSON files, you have seen CKAN. This short guide explains how to bid when the opportunity shows up as open data rather than on a portal.

What a CKAN tender feed actually is

CKAN is open-source software for publishing open data. When a government uses it for tenders, each opportunity is a row in a dataset — often a CSV or JSON file, sometimes behind a simple search page — listing the title, buyer, category, closing date, and, crucially, a link. The record exists for transparency and reuse, not for transacting. You cannot register or submit a bid inside a CKAN catalogue; there is no “submit” button and no vendor account.

The record is a pointer — follow it through

Think of the open-data record as a signpost. It tells you a tender exists and gives you enough to decide whether it is worth pursuing, but the actual solicitation lives somewhere else. Every useful record includes a link or a reference number that leads to the real thing: a documents page, an email contact, or the government’s official procurement portal where you register and submit. Your job is to follow that link through and complete the process on whatever system it lands you on.

So the workflow is simple but easy to get wrong:

  • Read the recordfor the essentials — buyer, scope, and above all the closing date and time.
  • Open the link to the source solicitation. Do not rely on the data fields alone; the linked documents are authoritative if they disagree with the summary.
  • Register and submit where the link takes you— which may be a full procurement portal, or may be email or sealed paper.

Watch for lag and gaps

Because open-data feeds are generated on a schedule, a record can lag the source by a day or two, and occasionally a link points to a page that has already closed or moved. Always confirm the deadline on the official solicitation, not just the dataset, and register early enough to leave room for surprises. If the record is thin, the reference number is usually enough to find the tender on the buyer’s own site.

Where the link leads

Where you end up decides what you do next. If the link opens a modern procurement portal, the universal steps apply — see the government-portal playbook. If instead it drops you at a PDF and an email address with no portal at all, follow how to bid when there is no portal. Either way, our directory saves you from trawling data catalogues by hand: we surface these opportunities alongside everything else, so you can browse open bids and click straight through to the source.

The bottom line

A CKAN tender record is a pointer, not a bidding system. Read it for the essentials, confirm the deadline on the official solicitation, and follow the link through to register and submit wherever it actually lives. It is a small topic with one big rule: never treat the data record as the finish line. For the larger world of transparency feeds this belongs to, see international open-contracting portals, and to find these opportunities without the manual search, start from how to find local government contracts.
