Tools for contractors

But:

  • Many current data-driven examples rely on proprietary data-sharing;
     
  • Most existing tools are custom-build for one particular country or context;
     
  • Where data is available, quality is often low;
     
  • Many countries lack any good quality published procurement data, or only have data on one stage of the process;

This is where OCDS comes in...

Interoperability

Quality

The Open Contracting Data Standard

A brief history

Built around data supply...

...and user need

Resulting in...

Field & identifier specifications

What to publish, and how to identify it consistently across the whole contracting process

 

JSON schema & flattened serialisations

How to publish data so that it can be read by different systems, and converted into accessible formats for different users. 

 

Publishing patterns

Stepping stones towards best practices for sharing data on the web: improving usability. 

The whole contracting process:

A worked example

1) Planning

2) Tender / formation

3) Enquiries

4) Award

5) Contract

6) Progress update

7) Contract ammendment

8) Completion

The pieces...

OCDS brings together data & documents from all stages of the contracting process

The contracting record

Releases and records

  • Real-time notices and updates;
  • As much information as the publishing system can share;
  • Linked to a contracting process ID;
  • Summarising the current state of the contracting process;
  • Bringing together data from different systems;
  • Providing change history;

Implementation approaches

  1. Map existing information sources
    What data do you have now? What data that users demand is missing? 
     
  2. Identify the identifiers
    Can you identify a whole contracting process?
     
  3. Engage users
    Understand the needs of your user community, and what they can bring to implementation.
     
  4. Choose architecture
    Centralised vs. distributed
     
  5. Publish & improve
