The VLKB resource data and metadata are highly depending on external public and private sources. We acknowledge the efforts of the staff of the primary repositories and archives from which we retrieved the data to be offered to the VIALACTEA members and, at the end of the project, to the astrophysical community (all the relevant starting points are listed in Appendix A). This research made use of Montage. It is funded by the National Science Foundation under Grant Number ACI-1440620, and was previously funded by the National Aeronautics and Space Administration’s Earth Sci- ence Technology Office, Computation Technologies Project, under Cooperative Agreement Number NCC5-626 between NASA and the California Institute of Technology.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.ELETTRONICOenConference paper10.1117/12.22316742-s2.0-85006373172000388804600016https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9913/1/VIALACTEA-knowledge-base-homogenizing-access-to-Milky-Way-data/10.1117/12.2231674.full?SSO=1https://arxiv.org/pdf/1608.04526.pdf2016SPIE.9913E..0HMFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE6 Computer Science and Informatics: Informatics and information systems, computer science, scientific computing, intelligent systems::PE6_10 Web and information systems, database systems, information retrieval and digital libraries, data fusion
