HiPS Working Draft 1.0

[Pierre Fernique]

Dear Apps members,

I'm pleased to announce that the *HiPS WD 1.0 is available on the IVOA 
document repository* (http://www.ivoa.net/documents/HIPS/index.html).

The HiPS standardization process has been decided one year ago at the 
Sydney Interop meeting in November 2015. This document derives from the 
HiPS note (http://www.ivoa.net/documents/Notes/HiPS/index.html) with 
additions and contributions of HiPS authors, contributors and HiPS 
producers who have accepted to participate to the elaboration of this 
document: Pierre Fernique (CDS), Mark Allen (CDS), Thomas Boch (CDS), 
Tom Donaldson (STScI), Daniel Durand (CADC), Ken Ebisawa (JAXA), Laurent 
Michel (SSC-XMM), Jesus Salgado (ESAC), Felix Stoehr (ALMA).

This working draft has been largely improved at the author level during 
the last 4 months and it should be (we hope) quite mature at this stage.

As HiPS is already used by the community, a collection of HiPS, tools, 
servers, clients are already available on various places. A list of 
links to some of them is provided below which can illustrate this document.

  * Clients: Aladin Desktop

  * Servers: Leiden, IRAP, SSC, CDS, AMIGA, svo.ba, IAS, ESAC, JAXA =>
    HiPS collection <http://aladin.u-strasbg.fr/hips/list> (~ 350 HiPS /
    100TB)
  * HiPS generators: Hipsgen
    <http://aladin.u-strasbg.fr/hips/HipsIn10Steps.gml>, Hipsgen-cat
    <http://aladin.u-strasbg.fr/hips/HipsCat.gml>

The authors of this document have voluntarily tried to minimalize the 
potential impact of this HiPS evolution/standardization on these already 
existing HiPS components. The specifical HiPS WD evolutions are mainly 
related to the meta data description (Obscore vocabulary, IVOA registry 
declaration, ...): a transitional period should be easily manageable 
without requiring the full regeneration of HiPS data collection.

Questions, comments, feedback are welcome. Do not hesitate to use this 
Apps mailing list directly.

Thanks a lot for all (other) authors and contributors
Pierre Fernique
