About WG5

The production and maintenance of International Standards in the field of Information Technology is carried out by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) through their Joint Technical Committee 1 (JTC1). Most of the work of JTC1 is, however, delegated to one of 20 Sub-Comittees (SCs) which, in turn, normally delegate the detailed work to permanent Working Groups (WGs).

SC22 is the JTC1 Sub-Committee responsible for "programming languages, their environments and system software interfaces", and carries out most of its work through its Working Groups. WG5 is the Working Group responsible for the development and maintenance of Fortran language standards.

WG5, like all other JTC1 Working Groups, consists of a Convenor and one or more Project Editors, all appointed by the parent Sub-Committee (SC22 in WG5's case), together with a number of individual members who are nominated by their National Member Bodies. It is not possible to apply directly to become an individual member of a Working Group without the support of an appropriate Member Body.

WG5 currently operates a two-tier development structure whereby the Working Group itself determines the broad technical content of the Standards and other formal documents that it is working on, but delegates much of the detailed work to "development bodies" who are charged with assisting the Project Editor for a particular project to create the actual text for the document. For the Fortran 95, Fortran 2003, Fortran 2008 and Fortran 2015 Standards, the US Fortran Committee (INCITS/PL22.3) was given the role of Primary Development Body. All WG5 working documents are available on the WG5 Electronic Document Archive.
