    Mapping VO Protocols/Metadata on top of existing archive
    
    Imagine you are in charge of a project on-line archive and you want to integrate it in the VO framework.
    Depending of the nature of your data (images, spectra, cubes, timeseries, catalogs) and on the completeness you want to reach the choice of protocols to implement will be different.
    The talk will make a review of the various possibilities according to various examples.

    Provenance of published data (postponed to Wed. 12:00)
    
    In the context of Open Science, data provenance has become a key piece of information to be provided with astronomical data. It is particularly essential to ensure trust in the data, thus promoting its reuse. As such, provenance is explicitly mentioned in the FAIR principles, which aim to make research data Findable, Accessible, Interoperable and Reusable. In practice, provenance should come with the appropriate granularity and level of details. Based on the IVOA Provenance data model, I will present several proposed solutions to capture, store and access provenance metadata for published data.

    CAOM within the ESAC Science Data Centre
    
    We would like to present an overview of the Common Archive Observation Model (CAOM), a general purpose data structure for use as the core data model of an astronomical data centre, designed by the Canadian Astronomy Data Centre (CADC). This common model is being used at the ESAC Science Data Centre (ESDC) in the contexts of the European Hubble and James Webb Space Telescopes Science Archives. We will demonstrate how we made possible to achieve a fruitful collaboration between Space Telescope partners by making use of a common observation data model, together with software projects built around it to enable the collection, exchange and verification of astronomical datasets.

    Providing access to Solar System & heliophysics data (VESPA / Europlanet)
    
    VESPA (Virtual European Solar and Planetary Access) has been focusing for nearly 10 years on adapting Virtual Observatory (VO) techniques to handle Planetary Science data. The objective of this activity is to build a contributive data distribution system where data services are located and maintained in research institutes, as well as in space agencies and observatories. VESPA is part of Europlanet, a series of programs funded by the European Union and dedicated to enforcing collaborative activities in Planetary Science both within and outside Europe. A new program called Europlanet-2024 has started in 2020 for a 4-year period. VESPA has defined an architecture adapted from the astronomy VO, and incorporating concepts and standards from other areas (Earth observation, Heliophysics, etc). The basic system uses the VO infrastructure: data services are installed in any location but are declared in a system of harvested registries with identifiers. Such services are interoperable via clients and tools, which also provide visualization and analysis functions. A specific access protocol (EPN-TAP) has been defined to allow the user to identify data of interest.

    Stored Data Retrieval through Virtual Observatory standards
    
    A service to retrieve data stored both in a long term preservation storage and in a fast access file system has been built at the Italian Astronomical Archives (IA2), based on Virtual Observatory standards. Some IA2 users have the need to store big sized data sets for a long term. At the same time, they need to recall these data when needed, perform analysis and store the new results. The proposed hardware solution is built on a long term preservation storage (tape library) connected to a fast access storage node for direct data exploitation. The software service has a data retrieval web interface based on IVOA standards: VOSpace for the data transfer and access, Single Sign-On (SSO) for the authentication, Group Membership Service (GMS) for the authorization, Universal Worker Service (UWS) to manage transfers. The plan for the future, after putting the service into production, is to exploit the use of IVOA standards to make this service interoperable with other similar in different data centres.

    ARTEMIX / Yaftis - Remote 3D viewer
    
    Yafits (Yet Another FITS viewer) is a standalone web application that enables remote visualisation of 3D data cubes hosted in FITS format on the server-side. The client can display images and spectra in order to quick-look the scientific content of the observations. The prime use is for radio-astronomy data, ie the ones from ALMA, IRAM/NOEMA or SKA but any kind of 2D or 3D FITS could be remotely accessed. Dedicated methods for radio data inspection have been implemented, like for instance the comparison with expected spectral lines frequencies compiled in molecular database catalogues. Yafits also uses SAMP for interoperability with Aladin or CASSIS to enable further data analysis. Yafits is integrated into ARTEMIX (ALMA RemoTE data MIning eXperiment http://artemix.obspm.fr) a web service that offers remote FITS visualisation of the ALMA scientific Archive since 2016 and which is continuously evolving with Yafits new features.

    Low Frequency Radio Astronomy on the VO
    
    We present the MASER (Measurement, Analysis, and Simulation of Emissions in the Radio range) toolbox, which enables science ready access to low frequency radio astronomy data. MASER focuses on time-domain and dynamic spectra data products and associated tools. Being at the interface between astronomy, heliophysics and planetary sciences, we make use of interoperable standards from each world (VOTable, TAP and UWS from the IVOA, EPN-Core from Planetary Sciences, or Das2 from heliophysics).

    Publishing survey data from the Observatorio Astrofísico de Javalambre (OAJ): The CEFCA Catalogues Portal
    
    The Centro de Estudios de Física del Cosmos de Aragón (CEFCA) is carrying out from the Observatorio Astrofísico de Javalambre (OAJ, Teruel, Spain) two large area multiband photometric sky surveys, J-PLUS and J-PAS, covering the entire optical spectrum using narrow and broad band filters. J-PAS and J-PLUS include coadded and individual frame images, dual and single catalogue data which include parameters measured from coadded images and photo-redshift computations. This contribution presents the CEFCA Catalogues portal (archive.cefca.es). A powerful web portal which has been implemented to publish all this survey data offering advanced tools, each suited to a particular need, for data search, visualization and download. This portal includes web user interface services such as sky navigator, object visualization, object list search, ADQL asynchronous queries interface, cone search and image search and download. All these web interface services support SAMP protocol to interoperate and communicate with VO-compatible applications. The CEFCA catalogues portal also offers all of this data through Virtual Observatory (VO) services like SIAP, SCS, TAP and catalogue and images HIPS. Moreover, the CEFCA Catalogues portal enhances data publication of these large surveys following FAIR principles to maximize research efficiency.

    The EVN data archive VO service
    
    At JIVE we are working on making interferometric visibility data from the European VLBI Network (EVN) archive available through VO protocols. For this purpose we have built a TAP service that serves ObsCore records. To create these records we wrote some special-purpose software in Python that extracts the necessary meta-data from FITS-IDI files. In this presentation I will discuss some of the choices made when writing this software as well as some further improvements we still intend to make before the service goes "live". I'll finish with some results on an attempt characterize the UV-coverage of VLBI data using a parametrization that is being considered for a Radio-specific extension to ObsCore.

    ESAP: the ESCAPE ESFRI Science Analysis Platform
    
    ESAP, the ESCAPE ESFRI Science Analysis Platform, is being developed to provide a flexible toolkit for constructing science platforms. It provides capabilities to quickly unite a range of data access and analysis services — in particular those developed by the ESCAPE project — behind a single, consistent but customizable, user interface. In this presentation, I will provide a brief overview of ESAP's aims, its architecture, and its current and expected future capabilities.

    Catalog of Coronal Hole detection in TAP service
    
    Coronal holes (CH) are seen as dark features on EUV images of the Sun. They are the source of the fast solar wind, and as such are closely monitored. The CH feature recognition module named SPoCA-CH was developped at the Royal Observatory of Belgium. Since 2010, one version of this software is running at LMSAL and provides near-real time detection of coronal holes. We would like to provide the outputs from an updated version of SPOCA-CH as a catalog for a VESPA TAP service. In this talk, we will discuss our progress, as well as questions regarding the encoding of tracking or provenance information within this TAP service.
