Abstract. We see the local content from peers organized in directories (i.e., on local ordered lists) of local representations of entities from the real world (e.g., persons, locations, events). Different local representations can give different “versions” of the same real world entity and use different names to refer to it. (e.g., George Lombardi, Lombardi G., Prof. Lombardi, Dad). Although the data from these directories are related and could complement each other, there are no links that allow peers to share and search across them. We propose a Distributed Directory System that constructs these connecting links and allows peers to: (i) maintain their data locally and (ii) find the different versions of a real world entity based on any name used in the network. We evaluate the approach in networks of different sizes using PlanetLab and we show that the results are promising in terms of the scalability.
