OpenCorporates (Largest Open Database of Companies in these World) is Creating Corporate Events Dataset

The OpenCorporates database currently contains data about 138 million companies located in countries around the globe.

From an OpenCorporates Blog Post:

2018-01-10_20-04-48OpenCorporates is creating a corporate events dataset, as part of the EU Business Graph project – to ensure that cross-border and cross-lingual data on corporate events is more readily available and accessible for all.


Events are critical moments in the life cycle of a company, including incorporation, dissolution, changes in structure, liquidation, mergers, winding up orders, annual general meetings and director actions. Yet, despite the obvious importance of these – both for society and business, they are extraordinarily difficult to find, particularly in a standardized form over multiple jurisdictions.

As part of the BusinessGraph project, OpenCorporates is creating a corporate events product that will:

  • Create a common model and schema for corporate events
  • Extract corporate events from changes in the official data at company registers
  • Infer events from government gazettes
  • Make this available both through the OpenCorporates website and as structured data via the API and bulk data dumps

This will provide greater visibility of internal events, including:

  • Incorporation and dissolution of companies
  • Changes in core attributes (including name, registered address, company type, industry codes)
  • Significant credit events (including company status, winding up orders, appointment of liquidators and changes in status on company registers)
  • Changes in leadership and directors
  • Changes in corporate structure (shareholders, increase in share capital and changing subsidiaries and parents)
  • Changes in licences and permissions
  • Announcements and filings, including annual accounts and annual returns
  • Useful metadata around the events (for example a company failing to file a return on time).
