Speaker Title Time Material
Markus Demleitner Getting COOSYS ready for 2025 15+3

Lecture Notes

As the real epoch progresses away from the convenient J2000.0 that the VO was born in, being able to automatically apply proper motions to catalogues in VOTables becomes more and more important. Our existing COOSYS element is not quite sufficient for that, and while the Coords model will be, its annotation will be a VOTable-external standard. In this talk I will discuss what it would take to make COOSYS work for pure-VOTable, Coords DM-compatible epoch propagation.

MOC lib Rust and its derivatives: MOCPy, MOCWasm,MOCCli and MOCSet

15+3 (21:38 in recording)

PDF Slides

MOC lib Rust is a Rust implementation of the MOC 2.0 standard. Originally developed to improve MOCPy performances, it has grown as a standalone library natively used in CDS internal projects.
Still at the very core of MOCPy, its functionalities are also available through MOCCli and MOCWasm. MOCCli is a command line utility, a simple executable file, pre-compiled for Linux, MacOS and Windows. MOCWasm is a JavaScript/WebAssembly library made to manipulate MOCs in Web Browsers.
Finally, in order to fulfill VizieR needs, we have been developing MOCset. MOCSet is a command line utility for building, updating and querying a set of MOCs. Its memory footprint is possibly low.

Supporting Prototype Implementations in PyVO

15+3 (39:05 in recording)

PDF Slides

PyVO implements the IVOA standards. As part of the standard approval process, new features are proposed and need to be demonstrated before the standard may be approved. PyVO may implement features that are not yet part of an approved standard.Such features are unstable, as the standard may be subject to reviews and significant changes, until it's finally approved.

The new `prototype` package provides support for such prototypes.
