---+ !Server-side Operations for Data Access version 1.0 Proposed Erratum 3: Wrong VOTable syntax in BAND example

Author: François Bonnarel

Date last changed: 2023-01-23

Date accepted:

---++ Rationale

In section 4.2, the VOTable excerpt given for the BAND PARAM is written following a wrong syntax for the MIN and MAX elements. The values of these elements are not consistent with the BAND arraysize attribute because they only contain a single number. MIN and MAX should actually contain arrays of 2 numbers. The MIN array should give the minimum length interval and the MAX array should give the maximum length interval. In addition the closing tag of the VALUES element is wrongly written<br />&lt;verbatim&gt;&lt;/VALUE&gt;&lt;/verbatim&gt;

instead of<br />&lt;verbatim&gt;&lt;/VALUES&gt;&lt;/verbatim&gt;

This bug orignally described on github in SODA issue #2 (https://github.com/ivoa-std/SODA/issues/2)

---++ Erratum Content

This Erratum proposes following changes.

---++++ Fix VOTable syntax

In [[http://ivoa.net/documents/SODA/20170517/REC-SODA-1.0.html#tth_sEc4.2][§4.2 "*SODA Service Descriptor from DataLink*"]] of !SODA-1.0, update the BAND  example MIN tag in

<verbatim><PARAM name="BAND" unit="m" ucd="em.wl;stat.interval"
    datatype="double" arraysize="2"      
    xtype="interval" value="">     
    <DESCRIPTION>The wavelength intervals to be extracted</DESCRIPTION>
    <VALUES>                                                           
      <MIN value="3e-7"/>
      <MAX value="8e-7"/>
    </VALUE>             
  </PARAM>  </verbatim>

from

<verbatim> <MIN value="3e-7"/></verbatim>

to

<verbatim> <MIN value="3e-7 5.5e-7"/></verbatim>

from

<verbatim><MAX value="8e-7"/></verbatim>

to

<verbatim><MAX value="2e-7 8e-7"/></verbatim>

from

<verbatim></VALUE></verbatim>

to

<verbatim></VALUES></verbatim>

---++ Impact Assessment

Fixing the VOTable syntax in an example will make no harm to any service and will avoid implementers writing code delivering incorrect VOTables.
