In this work we present a research line that focus on the design and implementation of a Directory Facilitator for a FIPA multi-agent platform. We will introduce three different approaches: a centralized version, a distributed one, and a hybrid solution. As we will explain below, the hybrid approach will have several advantages and it will be our choice for future implementations.Eje: Inteligencia artificialRed de Universidades con Carreras en Informática (RedUNCI
