1. Management Summary
1.1 JTC1/SC22/WG17 Statement of Scope
Development and maintenance of ISO/IEC standards related to programming
language Prolog
1.2 Project Report
1.2.1 Completed Projects
ISO/IEC 13211-2. Programming language Prolog-part 2 Modules
1.2.2 Projects Underway
Consideration of proposed drafts on Definite clause grammar,
and global variables and arrays.
1.2.3 Canceled Projects
None
1.3 Cooperation and Competition
2. Period Review
2.1 Market Requirements
Prolog is a niche language. It is extensively used by a small number of
users mainly for applications in configuration, web and CGI generation,
constraint handling and natural language.
It is taught in a significant number of universities.
2.2 Achievements
A draft of a Technical report on Definite Clause Grammars is out for ballot.
Paulo Moura is to be the editor.
Roger Scowen has submitted a set of defect reports and corrigenda which is
currently undergoing a ballot.
2.3 Resources
WG17 meets as needed, usually once a year, and works by electronic
correspondence between meetings. Four countries are participating in
meetings: Germany, Japan, the UK, and the USA.
3. Focus Next Work Period
An informal set of editors for the drafts is in place.
These will be reviewed at the October meeting in Sitges, Spain.
3.1 Deliverables
- Paulo Moura. Draft Technical Report Prolog Definite Clause Grammars.
N186
- Roger Scowen. Defect Reports and Corrigenda for ISO/IEC 13211-1 N187.
3.2 Strategies
None.
3.2.1 Risks
WG17 suffers from a decline in interest in supporting standardization
efforts.
3.2.2 Opportunities
It seems likely that Portugal is willing to take a more active role in Prolog standardization.
Locating the 2005 meeting with ICLP in Sitges was a success. The 2006 meeting is colocated with
FLoC (which includes ICLP) in Seattle
3.3 Work Program Priorities
The current priorities are the completion of the technical report on DCGs -- assuming that the ballot is successful.
There are also a number of issues with defects in part 1 that need to be resolved. further work on globals and arrays
is underway.
4. Other Items
This section includes items that are part of the Convener's Report, but not
part of the business plan.
Holding the meetings colocated with ICLP (the International conference Logic Programming
seems to be effective in increasing participation.
4.1 Action Requests at the Forthcoming Plenary
None
4.2 Schedule
A schedule for additional TR's is to be set at the meeting in Seattle.
4.3 WG17 Meetings
4.3.1 Recent Meetings
October 5th 2005 Sitges, Spain.
August 21st 2006, Seattle, Washington
None.
4.3.2 Future Meetings
To be scheduled, depending on the timing and location of ICLP 2007.
