The current, stable version of VOEvent is at <a href="https://www.google.com/url?q=https://www.ivoa.net/documents/VOEvent/20110711/&source=gmail-imap&ust=1690909773000000&usg=AOvVaw3tMK7cYHcVaSOl9jfM-q00" target="_blank">https://www.ivoa.net/documents/VOEvent/20110711/</a></p> * <p dir="ltr">Pick up discussion on Time Series Cube Data Model (2019), to get status, establish if it leads to a recommendation, etc. Does the datacube only have a time dimension, or also a spectral dimension? Of relevance for upcoming spectral time domain surveys. We need to ensue that it also fits high energy data (i.e. event files) => <a href="https://www.google.com/url?q=https://www.ivoa.net/documents/Notes/CubeDM/20190318/index.html&source=gmail-imap&ust=1690909773000000&usg=AOvVaw3b-FZEf9Zb6HbmC0aO7nFO" target="_blank">https://www.ivoa.net/documents/Notes/CubeDM/20190318/index.html</a></p> * Time search postponed in the Cone Search standard to the next major release * Evaluate synergies with HAPI protocol for heliophysics time domain data (https://vires.services/hapi/) * Form Galluzzi's talk at interop: radio time/frequency datasets. Similar to GW transients. Are there standards for this? * <p dir="ltr">Status of (S)TMOC => Space and Time coverage => Does this require updates? Is it currently being used? <a href="https://www.google.com/url?q=https://www.ivoa.net/documents/MOC/20220727/index.html&source=gmail-imap&ust=1690909773000000&usg=AOvVaw2lchjaDya3oBdU4ZR4gDn7" target="_blank">https://www.ivoa.net/documents/MOC/20220727/index.html</a></p> * <p dir="ltr">Cone search service that allows for time constraints</p> * <p dir="ltr">Other, dormant documents: <a href="https://wiki.ivoa.net/twiki/bin/edit/IVOA/VOEventRegExt?topicparent=IVOA.2023ARoadmap;nowysiwyg=0" rel="nofollow" title="VOEventRegExt (this topic does not yet exist; you can create it)"> VOEventRegExt </a> => Extension of the VO registry to describe a service providing VOEvents (dormant still 2014 ); [[STC]]-S => Space Time coordinate linear definitions (dormant still 2013)</p> ---++ Standard and Processes <br /> <span><span><span><!--<br /> * Set ALLOWTOPICRENAME = IVOA.TWikiAdminGroup <br /><br />--></span></span></span>
