IVOA Roadmap for 2016A

This outlines the roadmap for development activities by the various IVOA working and interest groups in 20116 between the Cape Town and Trieste Interops.

Applications

Data Access Layer

Data Model

Grid and Web Sevices

Registry

VOResource 1.1: A large number of minor issues are being fixed in this first overhaul of VOResource in 10 years. The main new feature is a capability to represent alternative identifiers (DOIs, ORCIDs, etc). Until Trieste, we want to reach consensus on the remaining open questions, with implementations, also in RegTAP following after Trieste.

SimpleDALRegExt 1.1: The adaption of SimpleDALRegExt to new DAL protocols (in particular SIAP 2.0) should see PR soon and should be ready for REC by Trieste.

Registry Interfaces 1.1: RFC soon [Theresa?]

TAPRegExt 1.1: This will be kept in lockstep to the progress of the TAP/ADQL updates.

Registering TAP tables: We are encouraging takeup of the Discovering Data Collections Note. Until Trieste, we in particular hope for more feedback from the CDS. Since they would like to link tables and (cone search) services, there is a (weak) link with VOResource 1.1. We believe such links could be done based on record-local tags.

Spatial searches in the Registry: We will continue to lay the software foundations in pgSphere (i.e., indexable MOCs). The existing footprintURL mechanism to distribute footprints will be good enough for prototyping.

Standards records: We would like to finally have StandardsRegExt records for all IVOA recommendation, and we will work with the WG chairs to have them generated. A page at http://wiki.ivoa.net/twiki/bin/view/IVOA/WriteAStandardsRecord has been set up to guide standards authors.

We will continue maintenance of the Registry system and contents, as well as our validation operations.

Data Curation & Preservation

Theory

Time Domain

Immediately following the Stellenbosch InterOp, VOEvent Transport Protocol 2.0 moved to RFC. We expect to devote the bulk of effort in this period to responding comments and, hopefully, pushing VTP towards full recommendation status.

Based on discussions at Stellenbosch, we will continue informally exploring prospects for time series representation within the VO.

We will seek to engage with the large facilities represented at the Stellenbosh "focus sessions", and explore how we can best help address their needs. As and when the promised (Ciardi's talk) LSSTC funded alert system study takes place, we will actively engage with this effort.
