Speaker Title Abstract Time Material
Massimo Costantini
(in person) 		Spoke3 Archive Infrastructure In this presentation, I will introduce a project currently under development and
funded by the European Union. The infrastructure is designed to provide access
to a curated set of Gaia data through a dedicated web portal, as well as via
TOPCAT and Python clients. We are implementing custom TAP and DataLink services
to support flexible and efficient data access tailored to scientific use cases. 		15'+3' pdf
Pat Dowler
(remote) 		DALI update This will be a short update on the current status of WD-DALI-1.2. The authors feel
the document is now ready to move forwards to RFC so we will also summarise all
the changes from the DALI-1.1 recommendation. 		15'+3' pdf
Grégory Mantelet
(remote) 		ADQL PEG grammar and validation One of the major changes in the next version of ADQL is the migration from a BNF
to a PEG grammar, which will provide a clearer definition of the language.
Unlike the ADQL BNF grammar, the PEG grammar must be machine-readable. This is
particularly important for language validation. In this talk, I will discuss the
challenges and progress of this transition to PEG. In parallel, I am working on
a validator. I will explain how it works and what its current status is. 		15'+3' pdf
All ADQL-next discussions A privileged time for discussions about the desired changes to the ADQL language.
After a reminder of the features already mentioned during the last
interoperability meetings, the discussions will begin in order to decide which
features should be included in the next ADQL version. Everyone is also invited
to contribute ideas and use cases for any desired language features. 		  pdf

Stéphane Erard
(remote) 		Accessing Solar System observations from ESO archive Solar System observations at ESO would benefit from an access via EPN-TAP,
similar to that provided on the HST archive. This is a report on a first test to
identify these data in the archive, and difficulties encountered during the
process. 		15'+5' pdf
Jose Osinde Lopez
(remote) 		Evolution of TAP toward a more stateless architecture TAP is a core component of the ESDC Archives, and to meet growing demands,we aim
to evolve it into a more scalable, fault-tolerant, and flexible service. While a
fully stateless architecture offers clear benefits, such as easier scaling and
improved resilience, some session state must still be maintained.
This presentation will focus on the architectural changes required to move
towards a stateless TAP implementation while preserving essential stateful
functionality. 		15'+5' pdf
Markus Demleitner
(in person) 		A management interface for persistent TAP uploads At the Malta interop, I have proposed a TAP extension to support
persistent uploads. What was still missing was a management interface
that allows users to extend the lifetime of their uploads and create
indexes. In this talk, I will fill that gap. 		15'+5' notes slides

Massimo Costantini
(in person) 		Spoke3 Archive Infrastructure In this presentation, I will introduce a project currently under development and
funded by the European Union. The infrastructure is designed to provide access
to a curated set of Gaia data through a dedicated web portal, as well as via
TOPCAT and Python clients. We are implementing custom TAP and DataLink services
to support flexible and efficient data access tailored to scientific use cases. 		15'+3' pdf

(remote) 		DALI update This will be a short update on the current status of WD-DALI-1.2. The authors feel
the document is now ready to move forwards to RFC so we will also summarise all
the changes from the DALI-1.1 recommendation. 		15'+3'

Grégory Mantelet
(remote) 		ADQL PEG grammar and validation One of the major changes in the next version of ADQL is the migration from a BNF
to a PEG grammar, which will provide a clearer definition of the language.
Unlike the ADQL BNF grammar, the PEG grammar must be machine-readable. This is
particularly important for language validation. In this talk, I will discuss the
challenges and progress of this transition to PEG. In parallel, I am working on
a validator. I will explain how it works and what its current status is. 		15'+3' pdf
All ADQL-next discussions A privileged time for discussions about the desired changes to the ADQL language.
After a reminder of the features already mentioned during the last
interoperability meetings, the discussions will begin in order to decide which
features should be included in the next ADQL version. Everyone is also invited
to contribute ideas and use cases for any desired language features. 		  pdf

Speaker Title Abstract Time Material
Stéphane Erard
(remote) 		Accessing Solar System observations from ESO archive Solar System observations at ESO would benefit from an access via EPN-TAP,
similar to that provided on the HST archive. This is a report on a first test to
identify these data in the archive, and difficulties encountered during the
process. 		15'+5'  
Jose Osinde Lopez
(remote) 		Evolution of TAP toward a more stateless architecture TAP is a core component of the ESDC Archives, and to meet growing demands,we aim
to evolve it into a more scalable, fault-tolerant, and flexible service. While a
fully stateless architecture offers clear benefits, such as easier scaling and
improved resilience, some session state must still be maintained.
This presentation will focus on the architectural changes required to move
towards a stateless TAP implementation while preserving essential stateful
functionality. 		15'+5' pdf
Markus Demleitner
(in person) 		A management interface for persistent TAP uploads At the Malta interop, I have proposed a TAP extension to support
persistent uploads. What was still missing was a management interface
that allows users to extend the lifetime of their uploads and create
indexes. In this talk, I will fill that gap. 		15'+5'  
Pat Dowler
(remote) 		TAP-1.2 - OpenAPI and user-tables This will be an update of the effort to make the user-managed tables feature an
optional part of the TAP standard using OpenAPI as the core specification. This work
touches WD-VOSI-1.2, WD-DALI-1.2, and the beginning of work on WD-TAP-1.2. 		15'+5'

Stéphane Erard Accessing Solar System observations from ESO archive Solar System observations at ESO would benefit from an access via EPN-TAP,
similar to that provided on the HST archive. This is a report on a first test to
identify these data in the archive, and difficulties encountered during the
process. 		15'+3'  
 
Massimo Costantini Spoke3 Archive Infrastructure In this presentation, I will introduce a project currently under development and
funded by the European Union. The infrastructure is designed to provide access
to a curated set of Gaia data through a dedicated web portal, as well as via
TOPCAT and Python clients. We are implementing custom TAP and DataLink services
to support flexible and efficient data access tailored to scientific use cases. 		15'+3'

Markus Demleitner A management interface for persistent TAP uploads At the Malta interop, I have proposed a TAP extension to support
persistent uploads. What was still missing was a management interface
that allows users to extend the lifetime of their uploads and create
indexes. In this talk, I will fill that gap. 		15'+3'
