The SDL-2010 version of the Specification and Description Language, which was approved by ITU-T in December 2011 was fully published by ITU-T at the start September 2012.
The ITU-T Study Group responsible for the System Design Languages:
- Abstract Syntax Notation One (ASN.1)
- User Requirements Notation (URN)
- Message Sequence Chart (MSC)
- Specification and Description Language (SDL-2010)
- Testing and Test Control Notation (TTCN-3)
The results of this meeting for System Design Languages was to consent for approval:
- the Annex to Z.104 the allows C concrete syntax to be used in SDL-2010;
- an Appendix to Z.109 giving an example concrete syntax for the abstract language of Z.109;
- the revised edition of Z.151 User requirements notation (URN) - Language definition
SG17 has proposed to the World Telecommunication Standardization Assembly (WTSA-12 <
http://www.itu.int/en/ITU-T/wtsa-12/Pages/default.aspx>) that all these System Design Languages languages except Abstract Syntax Notation One (ASN.1) are covered by a single study Question under SG17. Assuming that this is agreed by WTSA-12, this Question will meet in the first SG17 meeting of the 2013-2016 period 17 - 26 April 2013. The current work continues until the next meeting to the existing Questions - Q13/17 under myself (Rick Reed) and Q.14/17 under Dieter Hogrefe <
hogrefe#informatik.uni-goettingen.de>.
It is planned for the next meeting to update the SDL+ methodology document, and work on revising the Formal definition of the Specification and Description Language (Z.100 Annex F) for SDL-2010. Contributors to either work area are welcome. The SDL+ methodology is being coordinated by myself (Rick Reed). The Z.100 Annex F work is being coordinated by Edel Mary Sherrat <
