Change history

The following example shows how to publish data about a contracting process. Publish a release for each event in the process and update the record each time you publish a release.

Each subsection refers to a stage or event in the contracting process lifetime.

Note

For an introduction to the concept of a change history, see the releases and records primer.

Note

For guidance on how to set the id field on each release, see the easy releases worked example.

Tender

The London Borough of Barnet publishes a tender for cycle lane improvements. They issue the tender via a notice of intended procurement. This is also known as contract notice or opportunity notice.

The publisher creates a release to represent this notice. The release uses the 'tender' tag and provides the details in the tender section.

The publisher also creates a record for the new contracting process. The releases list includes the new and only release so far. The compiled and versioned releases are also created for the record. Since there is only one release, the compiled release is nearly identical to this release. Compare the release and the record using the box below.

Tender Update

The enquiry period has ended, and a few questions from potential suppliers have been received. The procuring entity issues a document with the responses to the enquiries received from bidders.

The publisher creates a new OCDS release with the 'tenderUpdate' tag.

The previous release is not changed. In the new release, the publisher adds a link to the new document in the tender.documents section. The tender.hasEnquiries field is also set to true. The publisher has decided to keep unchanged fields from the previous releases in the new one.

The record now has two immutable releases, and updated compiled and versioned releases. Note that the compiled release includes the enquiries document in the tender section. Also, the field tender.hasEnquiries has more than one entry in the versioned release.

Award

The procuring entity makes the decision to award the contract to Balfour Beatty. They issue an award notice.

The publisher creates a new OCDS release for the award. The record has the relevant information in the award section and uses the 'award' tag.

The parties array has a new entry with the supplier's information. The complete tender section is repeated, with the status field set to 'complete'. Previous releases remain unchanged.

The publisher adds the new release to the record. They also update the compiled and versioned releases. The compiled release reflects the changes to the awards, tender and parties sections. The versioned release includes a new change for the tender.status field.

Contract

By law, the procuring entity has to wait for complaints for a given period of time before signing a contract. Once the period ends with no complaints, the contract with the supplier is signed.

The publisher creates a new OCDS release using the 'contract' tag. They include all the relevant information in the contracts section.

The record gets updated to include the new release. The compiled and versioned release now have the new contract section. There are no updates to other sections.

Implementation

The supplier starts the construction work. After a while, the procuring entity makes the first payment to the supplier. The publisher creates a release to document this update in the process.

So far, the council used a single procurement system to manage the process. The procurement system published the previous OCDS releases.

The council now uses a separate financial system to manage payments. The financial system publishes the new OCDS release.

The procurement system and the financial system share a common contracting process identifier. This means that the two systems can publish releases using the same ocid.

The new release uses the 'implementation' tag. The contracts.implementation.transactions section includes the details of the payment.

Because the new release uses the same ocid, it is possible to update the record with the information.

Combining data from different systems

OCDS can be used to combine data from different systems. For more information refer to the guidance on system architectures.

The publisher adds the new release from the finance system to the releases list in the OCDS record. The compiled and versioned releases get updated to include the new transaction.
