IVOA Roadmap for 2015A

This outlines the roadmap for development activities by the various IVOA working and interest groups in 2015 between the Sesto and Sydney Interops.

Applications

VOTable 1.4

→ awaiting VODML serialization decision before starting a new cycle
→ call to read and comment the VODML mapping document

JSAMP
→ Support for https → try and see if a few standard adjustements will be required

HiPS
→ Study a new capability entry in the registry ?

Data Access Layer

Data Model

SpectralDM 2.0

Document stable, waiting for one pending implementation already provided

Somes comments received fue to this implemenation. Discussions to be taken to either update the spec covering some of the

suggestions or close SpectralDM 2.0 (and wait for recommendation) and include proposals into a possible SpectralDM 2.1 (draft for Sydney)

ObsCore 1.1

Stable draft provided in Sesto

VO/DML

Document stable with enough implementations

PR to be released after Sesto if agreement is obtained during Sesto (presentation of the status to be done during this interop)

VO/DML mapping

Working in a public draft in coordination with Apps. Not clear schedule (maybe PR for Sydney)

SourceDM

Initial discussions. First WD to be presented in Sydney

CubeDM 1.0, DataSetDM 1.0

Parallel activities. Documents stable. Waiting to have implementations in coordination with SIAv2 DAL spec

If no major problems are found before Sydney, maybe we could have a PR version in Sydney for both specs

It makes use of a more or less stable version of STC 2.0 model

STC 2.0

Preliminary stable UML provided. Spec still in a preliminary editorial phase.

WD to be presented during interop in spring 2016

Grid and Web Sevices

Registry

Semantics

Data Curation & Preservation

Education

Knowledge Discovery in Databases

Operations

Theory

Time Domain

VOEvent Transport Protocol

There's agreement within the IG that this is broadly ready to move forward from Working Draft. Will need to be "sponsored" by a WG (likely DAL).

VOEvent Registry Extension

Revision required following comments. Pending manpower; hopefully addressed this year.

VOEventContainer

Currently on hold pending manpower and refined understanding of requirements.

Time series representation

Enrique Solano has demonstrated that neither of the two approaches currently suggested for representing time series in the VO -- SimpleTimeSeries and Spectral Data Model v2 -- address all potential use cases. Working towards a comprehensive solution is a priority. Pending manpower to make progress.

Community engagement

Time domain has been identified as a priority by the IVOA CSP. Community engagement is key to this, and will require support from the larger IVOA machinery.
