The workshop will be held in conjunction with the 1999 International Conference on Logic Programming, which will take place in Port Las Cruces, NM, from November 29 to December 4, 1999.

Thus, we encourage anyone interested in attending the workshop to submit a note by electronic mail to the workshop organizers before July 1, 1999, at the address epontell aT cs.nmsu.edu.
