[edit] Motivation

Prolog implementations have progressed since the original ISO standard was written and as a result new predicates are commonly available but may be absent from the standard, have different names, or have different semantics. A revision to the standard aims to address these limitations.

[edit] How to get involved

  • contribute to this wiki
  • vote at ICLP 2007 in September.
  • join the ISO committee - see [1]
