Science platforms - IVOA May 2023 Interoperability Meeting

* back to main programme page *

There are two sessions dedicated to discussing science platforms at the interop.

The theme of these sessions will be to explore the state of the art for science platforms in astronomy, and to understand what the IVOA can do to support the development of the next generation of services needed to handle the increasing volumes of data available in the future.

The participants will be asked to reference three key questions about the IVOA's role:

  • What things from the IVOA worked ?
  • What things from the IVOA didn't work ?
  • What does the IVOA need to do next ?

Each of the sessions will have around 60 minutes for talks followed by 30 minutes set aside for a panel discussion.

Tess Jaffe
NASA Goddard Space Flight Center
NASA Astrophysics Platform 12' We'll give an overview of the planned NASA astrophysics science platform, particularly what it is intended to do and what it will NOT do. We'll then give a status update and describe some of the areas that connect to IVOA. pdf

SKA Observatory
SKA science platform 12' The SKA Regional Centres Network (SRCNet) is being established to handle the massive data produced by the Square Kilometre Array (SKA) project. This network includes nodes across 16 countries. The definition of standardised federated protocols is crucial for a future harmonised network. The International Virtual Observatory Alliance (IVOA) provides adequate composition and experience in promoting interoperability. Implementing IVOA-like protocols within the SRCNet would enable standardised data exchange, storage, and analysis. These protocols will not only address immediate challenges but also establish a foundation for future connections between astronomical science platforms globally. google slides
Simon O'Toole AAO Macquarie University AAO Data Central's adventures in the VO 12' Data Central is now a mature science platform with many different facets, including implementations of several IVOA standards. We offer IVOA services like TAP, SIA, SSA, SCS and DataLink, but also a service that aggregates a large range of IVOA services together for single objects of interest. In this talk, I will give an overview of how the IVOA has helped our journey to FAIR data, where we are hitting roadblocks, and some possible new directions. pdf
Yunfei Xu
China-VO Science Platform 12' The China-VO science platform is a cloud-based platform that leverages modern infrastructure to facilitate diverse astronomical research. To ensure flexibility and scalability, we have adopted a microservice architecture, enabling the creation of independent applications within the platform. Our implementation incorporates various IVOA standards, which serve as the bedrock for seamless data access and visualization functionalities. In this presentation, we will highlight a compelling use case of the platform: the Time Domain Astronomical Information Centre (TDIC). By showcasing the TDIC, we aim to illustrate the exceptional features and capabilities of the China-VO science platform. PPTX

CfA Nexus R&D 12' In this talk we present the Center for Astrophysics and Harvard & Smithsonian Research and Development effort to provide a multi-wavelength science platform catered to scientists across departments and wavelength domains. The effort is aimed at integrating heterogeneous data using IVOA standard protocols, as well as providing a platform for bringing astronomer's science close to the data, in preparation for the ambitious vision of enabling Peta-scale Astronomy through missions currently being developed at the Center for Astrophysics. pdf
All Discussion 30' Panel discussion covering the topics raised in the talks, with emphasis on the IVOA's role going forward.
What does the IVOA need to do next ?

Session II

Time: Thursday 11th May 14:0015:30 CEST [session #15]

Vicente Navarro
ESA Datalabs, an Open Digital Platform for Innovation and Collaboration in Space Science 12' Nowadays, the sheer amount of data collected from space-borne and ground-based sensors, is changing dramatically past approaches towards data processing and storage. In the era of Big Data, Machine Learning and seamless collaboration, data transfers are being replaced by algorithm transfers and computation close to the data. Through a Software as a Service (SaaS) delivery model, ESA Datalabs leverages technologies such as, Docker, Kubernetes, JupyterLab and Data Science packages to implement a Digital Platform for innovation in Space Science. pdf
Mario Juric
University of Washington
HiPSCat: extending HiPS to for highly scalable large-scale catalog analyses 12' HiPSCat: Motivated by Rubin, we're developing a partitioned dataset format enabling distributed analysis, joins, and cross-matching of catalogs at PB+ scales. The aim is to enable analytics tools allowing users to perform joint, full-catalog, analyses on science platforms. We're looking for feedback and collaboration opportunities. pdf
Robert Nikutta
NOIRLab's Astro Data Lab science platform 12' In six years of operations Data Lab has attracted over 2500 users. It hosts over 120TB of catalogs and 2+PB of images near compute resources. We are now also serving massive spectroscopic surveys including the imminent DESI EDR. R&D is under way to migrate some services to the cloud, beginning with the Jupyter notebook server. This talk will report on progress and challenges ahead. pdf
Brian Major
CANFAR Science Platform and the IVOA 12' The CANFAR Science Platform allows users to build, publish, and execute docker containers both interactively and programmatically. This has been a success, but challenges lay ahead through participation SKA SRCNet and the Vera C Rubin Observatory, where data and processing are geographically distributed and controlled by different institutes. We require mechanisms to allow this network of heterogeneous science platforms to work together. pdf

Gaia Data Mining platform 5'' We are developing a data mining platform using Zeppelin and Spark to analyse data from Gaia. Our deployment provides local low-latency access to the Gaia data partitioned and formatted as Parquet files. We are interested in how we could describe and register and publish the Parquet formatted data and the service associated with it in the IVOA, enabling others to use our data and/or service. pdf
