Category C liaisons are proposed by JTC 1 to the ITTF after receiving a recommendation from the appropriate JTC 1 subsidiary body, i.e., an SC (or WG reporting directly to JTC 1) ... Each request for liaison status forwarded to JTC 1 from an appropriate JTC 1 subsidiary body must contain a statement of expected benefits and responsibilities accepted by both the JTC 1 organization and the organization requesting liaison status. ..."

Reason for Liaison Ada-Europe is an international organization, set up to promote the use of Ada. It aims to spread the use and the knowledge of Ada and to promote its introduction into academic and research establishments. Above all, Ada-Europe intends to represent European interests in Ada and Ada-related matters. 

In its current form, Ada-Europe was established in 1988. As there is no European legal framework to govern such organizations, it was established according to Belgian Law. Currently, the member organizations are: Ada-Belgium, Ada-Denmark, Ada-Deutschland, Ada-France, Ada-Spain, Ada in Sweden, Ada in Switzerland and Ada UK. Individual members of these organizations can become indirect members of Ada-Europe. Direct membership is available to individuals in countries without national member organization. At the moment, Ada-Europe has about 350 indirect members. 

The best-known of Ada-Europe's activities is its annual conference, now in its 22nd year, which provides the European forum for researchers and users of Ada and other technologies geared towards reliable systems. Ada-Europe publishes the Ada User Journal to keep its members and others abreast of the latest developments related to Ada.

In the past, Ada-Europe members have played an important, but individual, role in the standardization work of SC22/WG9. For example, ISO/IEC 18009 incorporates technical material provided by Ada-Europe members.

A category C liaison relationship will permit the exchange of technical materials on a systematic basis permitting WG9 to improve the technical review of its documents and increase their relevancy to the Ada user community and the marketplace. 

Type of Liaison Formal Liaison

" ... Formal liaison is a formal exchange of documents between two organizations for the purpose of keeping each other informed of their work."
