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'

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'
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.

Speaker	Title	Abstract	Time
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'
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		15'+5'
