The panel on extensions of the language of Logic Programming has considered a number of important issues in this respect, and in particular discussed this issue for the Answer Set Programming Paradigm.
There seems to be general agreement that extensions to the language of LP/ASP are necessary, and that there is a variety of possibilities for such extensions. Some guiding principles have been pointed out for the design of such extensions, which might prove valuable. While applications and usage of LP/ASP might be a driving force for LP/ASP extensions, the knowledge representation and epistemological perspective of LP should not be forgotten about, and carefully respected.
Couplings of ASP with other programming languages, or database query languages, is an interesting issue, which at present is not solved and requires more work.
Overall, the panel and the discussion made a very optimistic impression about the further development of extensions to ASP and LP.
