---+ !Server-side Opertaion for Data Access version 1.0 Proposed Erratum 1: ID parameter UCD amendment

Author: Marco Molinaro

<!-- Date accepted|rejected: 20NN-MM-DD -->

---++ Rationale

!SODA protocol uses the *ID* parameter to specify opaque identifiers to the dataset or file to be accessed.
The UCD specified in the !SODA-embedded 3-factor semantics is reported in the REC text as 
<verbatim>meta.ref.url;meta.curation.SODA</verbatim>
This is not a valid UCD both for the, probably, typo of the added *.SODA* part and the fact that meta.curation
identifies a *man/organization responsible for the data* as per the UCD vocabulary.

---++ Erratum Content

This Erratum proposes to change, in §3.2.1 "*ID*" of [[http://ivoa.net/documents/SODA/20170517/index.html][SODA - Version 1.0]] 
the UCD in the sentence
<verbatim>
The UCD describing the ID parameter is meta.ref.url;meta.curation.SODA
</verbatim>

from

<verbatim>meta.ref.url;meta.curation.SODA</verbatim>

to

<verbatim>meta.ref.uri;meta.dataset</verbatim>

amending so the typo, the reference to a dataset rather than an organization and using a UCD referring to an identifier rather than a resource locator.
Using *meta.id* won't work together with *meta.ref.uri* being both *P* UCD words.

---++ Impact Assessment

Being the UCD only used in !SODA to describe uniquely the *ID* parameter using the 3-factor semantics, this change won't probably have any impact
on the service provider's side (requiring only a change in the service description). On the client side it has o be evaluated whether applications need
changes. However it has to be noticed that there are few !SODA service currently in place (and none registered).
