DAL 1

Time: Tuesday 9 May 11:00 CEST [session #6]

Location: Plenary room

Speaker	Title	Time	Material	Abstract
Joshua Fraustro	Python TAP implementation at MAST: Lessons Learned	12'+3'	pdf	STScI will be launching its overhauled TAP service rewritten as a Python-based microservice this summer. We’ll cover the challenges, quirks, and lessons learned implementing a set of standards that continue to evolve while attempting to maintain years of client compatibility.
Patrick Dowler	TAP-next: user-managed persistent tables	15'+14'	pdf	CADC/CANFAR has developed extensions to TAP-1.1 to support users and projects creating and managing their own tables in a TAP service. There is interest from several other community members to adopt this and it seems like a useful set of optional features to be specified in TAP-next aka TAP-1. There are open questions and some rough spots that need work so this talk is seeking "agreement in principle".
Tamara Civera	ADQL vector functions implementation in the Observatorio Astrofísico de Javalambre (OAJ)	12'+3'	pdf	The Observatorio Astrofísico de Javalambre (OAJ, Teruel, Spain) is carrying out two large area multiband photometric sky surveys, J-PLUS (Cenarro et al. 2019) and J-PAS (Bonoli et al. 2021), covering the entire optical spectrum using narrow and broad band filters. To publish these surveys data, the CEFCA Catalogues portal (archive.cefca.es) has been implemented, offering web user interface services as well as VO services like SIAP, SCS, TAP and catalogue and images HIPS. Surveys data includes the catalogues of the sources detected in the images with the photometry for each object in the different bands measured using different methods. All this information is stored in tables containing massive amounts of vectors. In this contribution we present our implementation of some ADQL vector functions, and a proposal to add to ADQL a new concept called "Enumerations" which can be used as constants in queries and can make the access to the data of those vectors easier for the user.
Grégory Mantelet	ADQL-next	15+14	pdf	ADQL-2.1 is currently under RFC and will hopefully become a REC in some weeks. So, it is now the time to prepare the next version. Some features were already proposed for ADQL-2.1 and unfortunately postponed. So, let's talk about them, but also share any other ideas for next version of ADQL. This talk will start with a brief listing of already known propositions and then will be completely open to discussion.

ConeSearch Splinter

Time: Tuesday 9 May 12:30 CEST [lunchtime session]

Location: Plenary backstage area

Discussion on next steps for ConeSearch - planning a small update before the big step to add time. Should UCDs be changed to v1.1 in the update?

Note: This session may not be on zoom - if you would like it to be, please contact James or Grégory.

DAL 2

Time: Thursday 11 May 16:00 CEST [session #16]

Location: Plenary room

Speaker	Title	Time	Material	Abstract
Petr Skoda	Echelle spectra and the ways toward their VO interoperability	12'+3'	pdf	Echelle spectrograph is one of the most precise astronomical instruments delivering the highest spectral resolution and widest spectral range together. Currently, it is the crucial instrument for exoplanet research capable of delivering radial velocity precision of the order of several meters per second. This is unfortunately achieved at the expense of extremely complicated reduction procedures resulting in a zoo of custom storage formats requiring individual programmatic access to achieve the maximum precision. As there is no generally accepted format for interoperability of echelle spectra, the providers convert the results in a format of 1D vector as in single-order spectra leading to the severe degradation of its potential. As the future exoplanet missions as e.g., PLATO are inherently dependent on a multitude of different ground-based observatories equipped with echelle spectrographs, there is a great challenge for the IVOA to develop the proper interoperable data format and access patterns (supported by massive queries and server-side processing). We will give an overview of the problems in echelle spectroscopy and suggest possible ways for an IVOA standard.
Margarida Castro Neves	LineTAP implementation in SPLAT-VO	12'+3'	pdf
Patrick Dowler	DALI	12'+3'	pdf
François Bonnarel	Transition from SIA to DAP and SODA 1.1	12'+3'	pdf	The talk insists on a few strong drivers for evolution of these standards and proposes a roadmap
Grégory Mantelet	Simbad's Cone Search implementation	12'+3'	pdf	Simbad has always provided a Cone Search service following the SCS-1.0 standard. However, this service became a bit oldish, especially in term of performances. New features are also required by some users. So, recently a new implementation of the Simbad's Cone Search is online with a different technology and new features. It also gives the occasion to make a step forward Cone Search 1.1 by following some modifications already listed in the last Working Draft and by introducing few other desired features.
Various	DAL RFC Overview	12'+3'	ADQL DataLink	Lightning talks on each RFC currently open
