Subject: PEN: UDF catalogue 1.2
Message-ID: <9cdc49c6-f33c-4324-9a75-de962098c51f@astro.unistra.fr>

Dear DAL members,

This is a quick announcement for a minor revision of the
UDF Catalogue Proposed Endorsed Note - version 1.2. This PEN is
now released and may become an Endorsed Note at the next TCG meeting.

So, if this is of some interest for you, please have a review very soon 
as it
may be voted at the next TCG meeting. For questions and comments, Markus 
and Jon
will be glad to collect and answer to them.

For reminder, this note aims to gather ADQL user defined functions 
recommended
by the IVOA. Such functions must be implemented by at least two 
implementations
in order to appear in this note. Those functions are prefixed by `ivo_`.
ADQL/TAP service providers are strongly encouraged to follow the 
definition of
functions listed there for a given feature if already covered by a 
function of
this document. The goal is to prevent the dissemination of variations of 
similar
functions by defining a single function signature and behavior.
Example of UDF already endorsed: `ivo_healpix_index(hpxOrder, long, lat)`.

The previous version was EN-1.1 
<https://www.ivoa.net/documents/udf-catalogue/20231117/index.html> and 
was released on the 10th of October 2023.

In this PEN-1.2 /(see the IVOA doc. version -
https://ivoa.net/documents/udf-catalogue/20240807/ - which matches
the version on GitHub <https://github.com/ivoa-std/udf-catalogue>)/, Jon 
and Markus have added the following functions:

- `ivo_epoch_prop` and `ivo_geom_transform` as astrometry function
- `ivo_simbadpoint` as convenience function
- `ivo_normal_random` as a statistics function
- `ivo_to_jd` and `ivo_to_mjd` as a datetime functions
- `ivo_hms_to_degrees` and `ivo_dms_to_degrees` as a celestial 
conversion functions

Cheers,
Gr?gory and Joshua

Dear all,

For the record, to avoid misunderstandings:

  *   PEN-1.2 does not contain `ivo_epoch_prop`(the ESA implementation is not yet ready);
  *   PEN-1.1 did contain the `ivo_epoch_prop_pos`simplified version and this UDF is accordingly part of the UDF Catalogue 1.1.

Best wishes,

Jos

Dear Jos,

Yes, you're perfectly right. Sorry for this mistake. `ivo_epoch_prop` is 
not yet part of the UDF Catalogue. This is the subject of the frozen 
PullRequest #20 <https://github.com/ivoa-std/udf-catalogue/pull/20>. I 
should have been more careful when sending this email. Thank you for 
raising these points.

Cheers,
Gr?gory

Subject: Call for contributions to DAL WG session at Nov. 2024 Interop
Message-ID: <675d7e53-0fd5-4efd-8256-bd80c8b42016@astro.unistra.fr>

Dear DAL members and IVOA,

The November IVOA Interoperability Meeting 
<https://indico.ict.inaf.it/event/2996/> will take place in La Valletta, 
Malta from 14 - 17 November 2024. Remote attendance will also be supported.

We invite you to contribute to the DAL session with a DAL related topic.

For reminder, DAL stands for Data Access Layer. This Working Group aims 
to define standards and protocols to access data in an interoperable 
way. Here are few examples of well-known DAL standards: (Simple) Cone 
Search, SIA (image access), SSA (spectra access), TAP (Table Access 
Protocol) and ADQL (SQL-like language to query a database). The full 
list of DAL standards is available on the IVOA Documents page 
<https://www.ivoa.net/documents/>.

During this interop., you can contribute, remotely or in-person, with a 
talk presenting implementations, sharing your experience as user, 
presenting and discussing progress on a DAL standards, or presenting 
use-cases. If you are interested, please send your contribution (with a 
speaker name, a title, and ideally an abstract) to 
gregory.mantelet at astro.unistra.fr and jfraustro at stsci.edu. If you are 
unsure about the suitability of a talk, or are a first time contributor, 
please get in contact with us and we can discuss it.

Cheers,
Gr?gory Mantelet and Joshua Fraustro
