In this way, this standard is focused on access to metadata related to the planning of a certain observatory, more than on access to the scientific data products. Also, the data model will be focused on discovery of planned observations, which is very useful information for multi-wavelength coordination observations, re-planning information propagation, follow-up of Targets of Opportunity alerts, preparation of proposals, etc. <P />As with ObsCore, a serialisation into a relational table is defined, which allows users to run complex queries using the IVOA Table Access Protocol. The document also prescribes how to register and discover ObsLocTAP services.ELETTRONICOenhttps://ivoa.net/documents/ObsLocTAP/20210724/REC-ObsLocTAP-1.0-20210724.pdfhttps://ivoa.net/documents/ObsLocTAP/20210724/2021ivoa.spec.0724SINF/01 - INFORMATICAERC 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
