---++ SSA-1.1 and Spectrum-1.1 Proposed Recommendation: Request for Comments

This document serves as the RFC center for the Proposed Recommendation entitled "Simple Spectral Access, Version 1.1". 
At the same time the Spectrum Data model document has been updated 
in order to correct minor inconsitencies in notation with respect to the SSA protocol standard document ( Utypes mispell, UCD, Fits keywords completed.)

Latest version of SSA can be found at:
   * http://www.ivoa.net/Documents/SSA/20110417/

Latest version of Spectrum Data Model can be found at:
   * http://www.ivoa.net/internal/IVOA/IVOADMSpectraWP/PR-SpectrumDM-1.1-20110318.pdf

Additional discussion about any of the comments or responses can be conducted on the Data Access Layer mailing list, dal@ivoa.net and on the Data Model mailing list, dm@ivoa.net However, please be sure to enter your initial comments here for full consideration in any future revisions of this document

---++ Comments from TCG member during the TCG Review Period: 01 June 2011 - 28 June 2011

WG chairs or vice chairs must read the Document, provide comments if any and formally indicate if they approve or not the Standard.

IG chairs or vice chairs are also encouraged to do the same, althought their inputs are not compulsory.

Comments on SpectrumDM 1.1 - IVOA.ChristopheArviset 2011-06-07

All my comments are mainly editorial or related to document formatting. I'll be happy to approve SpectrumDM 1.1 once they've been addressed.

[Section 1 Introduction and Motivation]
This section should already clearly indicate the reason for SpectrumDM 1.1, which is mainly for corrections coming from feedback implementation and does not represent any fundamental changes wrt the existing Recommended SpectrumDM 1.03 released on 29 October 2007. It should also indicate its "pairing" with SSAP 1.1.

[Section 1.1 Change log]
This section should also clearly indicate the Recommended SpectrumDM 1.03 released on 29 October 2007

[Section 1.2 IVOA Architecture]
Last paragraph should either be rewritten to better reflect the relationship between SpectrumDM 1.03, SpectrumDM 1.1 and the upcoming SpectrumDM 1.2 or should be removed (one could argue why we need a reference to SpectrumDM 1.2 in the SpectrumDM 1.1 document?).

[References] 
The references section should be udpated with latest version of standards and should contain all IVOA standards introduced in Section 1.2

Various formatting issues:
   * Blank pages that should probably be removed: 18, 22, 66, 81
   * Landscape pages that are cut on the border: 19, 20, 21, 23, 24, 25, 26
   * Pages cut on the border due to too long text: 40, 41, 55, 57



Comments on SSAP 1.1 - IVOA.ChristopheArviset 2011-06-07

All my comments are mainly editorial. I'll be happy to approve SSAP 1.1 once they've been addressed.

[Page 2] Reference to VOSI should be updated as it has now become a REC

[Section 1] Introduction
As agreed, together with the IVOA Architecture Diagram, some text should explain the relationship between SSAP and the other IVOA Standards present on that diagram.

The SSAP text used for the IVOA Architecture document could probably be inserted as is:

Simple Spectra Access Protocol (SSAP) defines a uniform interface to remotely discover and access one dimensional spectrum coming from data and metadata collections. SSAP is based on the Spectrum Data Model (itself making reference to the CharDM) that is capable of describing most tabular spectrophotometric data, including time series and spectral energy distributions (SEDs) as well as 1-D spectra. SSAP can be used from VO applications to access the associated spectrum resources.
As with most of the IVOA Data Access Protocols, SSAP makes use of VOTable for metadata exchange, STC, UCD, Utypes and Units for metadata description.
An SSAP service is to be registered into the VO Registry, using the associated registry standards (in particular Resource Metadata, VOResource and SimpleDALRegExt specifically for Data Access Protocols such as SSAP). Once registered, an SSAP service will get a unique IVOA Resource Identifier. Furthermore, an SSAP service should be registered with its supported interfaces through the VOSI standard.
