This specification defines an interface for searching this resource metadata based on the IVOA's TAP protocol. It specifies a set of tables that comprise a useful subset of the information contained in the registry records, as well as the table's data content in terms of the XML VOResource data model. The general design of the system is geared towards allowing easy authoring of queries.ELETTRONICOenResearch reporthttps://www.ivoa.net/documents/RegTAP/20191011/REC-RegTAP-1.1.pdfhttps://www.ivoa.net/documents/RegTAP/20191011/index.html2019ivoa.spec.1011DFIS/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
