Copenhagen - 7 June 2012. At the European Data Forum (EDF) 2012, founder Chris Taggart presented the added-value of  an open identifying system for companies. Through his involvement in the Core Business Vocabulary Working Group, a similar identifying system is part now part of the Core Business Vocabulary. is an independent open data initiative, maintaining information of over 43 million companies in 50 jurisdictions, including 23 US states. In his presentation at the European Data Forum 2012, founder Chris Taggart explained that much of the added-value the open company register brings is based on the fact that it uses an open identifying system for legal entities: Each legal entity has a unique resource identifier (URIs) that is IP-free and is based on identifier of the company in its local company register.

According to Crhis Taggart, having an open identification system for legal entities is a minimum for sharing information about companies in an interoperable way. It allows among others the following services to be developed on :

  • Company search and has a simple search for companies, allowing search across multiple jurisdictions to be executed within minutes, rather than days required to contact the local company registers that are not openly accessible on the Web. Information that is not available in one register is linked to information from another register. This allows users to triangulate data and obtain information in minutes that was previously nearly impossible to obtain.
  • Entity reconciliation: offers reconciliation web services that allow any user to cleanup of messy company names, and associate them with unambiguous company URIs. Via integration with tools like Google refine company information can be associated with unique company identifiers.
  • Enriched company data: uses its open identification and reconciliation services to enrich its company data with information such as company addresses, international trademarks, UK government spending,  health & safety violations, etc. 

Since November 2011, participated in the ISA Core Vocabularies Working Group, building consensus on a fundamental data model for identifying and describing fundamental information about legal entities. One of the main benefits that the Core Business Vocabulary will bring is the open identification system of companies, similar to the one foreseen by
