  The VIALACTEA project has a work package dedicated to Tools and
Infrastructure and, inside it, a task for the Database and Virtual Observatory
Infrastructure. This task aims at providing an infrastructure to store all the
resources needed by the, more purposely, scientific work packages of the
project itself. This infrastructure includes a combination of: storage
facilities, relational databases and web services on top of them, and has
taken, as a whole, the name of VIALACTEA Knowledge Base (VLKB). This
contribution illustrates the current status of this VLKB. It details the set of
data resources put together; describes the database that allows data discovery
through VO inspired metadata maintenance; illustrates the discovery, cutout and
access services built on top of the former two for the users to exploit the
data content.
