Server-side Operations for Data Access version 1.0 Proposed Erratum 2: Wrong VOTable syntax in polarization example

Author: François Bonnarel

Date last changed: 2023-01-20

Date accepted: 2023-04-05

Rationale

In section 4.2, the VOTable excerpt given for the POL PARAM is written following a wrong syntax for the OPTION element. The value of this element is coded as a content of the element instead of as a value of the "value" attribute of the element. In addition the closing tag of the VALUES element is wrongly written

</VALUE>

instead of

</VALUES>

This bug orignally described on github in SODA issue #1 (https://github.com/ivoa-std/SODA/issues/1)

Erratum Content

This Erratum proposes following changes.

Fix VOTable syntax

In §4.2 "*SODA Service Descriptor from DataLink*" of SODA-1.0, update the Polarization example OPTION tags in

<PARAM name="POL" ucd="meta.code;phys.polarization"
datatype="char" arraysize="*" value="">
<DESCRIPTION>Polarization states to be extracted.</DESCRIPTION>
<VALUES>
<OPTION>I</OPTION>
<OPTION>V</OPTION>
</VALUE>
</PARAM>

from

<OPTION>I</OPTION>

to

<OPTION value="I"/>

from

<OPTION>V</OPTION>

to

<OPTION value="V"/>

from

</VALUE>

to

</VALUES>

Impact Assessment

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