CADDY History

To facilitate the newly established Directive 91/414/EEC procedure for (re-)registration of plant protection products ECPA, the EU Commission and the European Member States agreed in 1995 to jointly develop an electronic standard for the submission of plant protection dossiers in Europe under the acronym "CADDY".

The "Joint EU Member States / ECPA Data Transfer Steering Group" consisting of five experts from European Member States, a representative from the EU Commission and five experts from ECPA was established in June 1995 to work out a solution to meet their strategic goals:

To facilitate

  • the provision of dossiers for pesticides to regulatory authorities,
  • the long-term archiving of such dossiers,
  • and the accessibility of information contained in such dossiers in a cost-effective manner using electronic media.

The original CADDY format specification was developed in 1995 in order to provide an effective electronic transport medium for complete submissions from the applicant to the reviewer. At that point, study reports used for the preparation of submissions existed primarily in paper form in an archive or as paper scans in an electronic archive. The first CADDY specification was deliberately kept simple, to allow rapid implementation of a robust system and in a cost-effective manner using electronic media.

These strategic objectives have been largely achieved in Europe, with electronic submissions in the CADDY format now the norm and the number of paper dossiers distributed to EU member states significantly reduced.

As a next step, an additional strategic objective of providing optimized support for the examination and assessment of dossiers by regulatory authorities was added. A driving force for the development of CADDY-xml has been the need to integrate the dossier submissions with the internal information systems of regulatory authorities.

Over the past 10 years, document management technologies have evolved considerably and XML-based web technologies have become standard. Applicants are increasingly storing study reports in native electronic formats (i.e. without scanning step). Also, additional electronic format - other than TIFF - suitable for long-term storage of documents have emerged and become ISO standards, such as PDF/A.

In spite of its success in replacing paper dossiers in Europe, the uptake of CADDY has been limited to agrochemicals in Europe, with other regions pursuing a different approach based on PDF. The CADDY standard, therefore, needs further development to make it useful as a tool for dossier and data exchange in the context of global work sharing, as it is currently being promoted by OECD. In addition, there is a clear trend towards more structured data submission based on OECD templates which needs to be appropriately supported by modern technology.

For this reason, the ECPA eSEG started work with the EU Commission and some EU member states to further explore a more flexible development of the CADDY standard.

The initial CADDY-xml Specification has been finalized in June 2005 and agreed in the Joint Caddy Steering Group. The CADDY-xml Converter is a conversion software that transforms CADDY dossiers into CADDY-xml dossiers. Both software and specification are available for download ( CADDY-xml Specification / Converter).

With these tools (specification and conversion software), applicants and reviewing authorities are able to create and exchange self-contained dossiers and a basis for further developments to support and facilitate work-sharing has been created.

International progress
In mid 1996 the US and Canadian authorities and industry joined this steering group and the group was renamed the Joint CADDY Steering Group (JCSG). Representatives from the Pesticide Regulatory Management Agency of Canada (PMRA) and the Canadian industry and representatives from the Environmental Protection Agency (EPA) of the United States and the American Crop Protection Association (ACPA) joined the group, and provided their invaluable input for the development of the current CADDY retrieval software until 1999.
