---+ ObsCore 1.1: Erratum 1

Author: DM WG

Date last changed: 2018-12-19

Date accepted:
---++ <span style="background-color: transparent;">Rationale</span>

<span style="background-color: transparent;">This erratum corrects a few issues noted in the </span> [[http://www.ivoa.net/documents/ObsCore/20170509/REC-ObsCore-v1.1-20170509.pdf][ObsCore-1.1 document ]].

   1 <span style="background-color: transparent;">Table 6, page 56, lists </span><span style="background-color: transparent;">invalid UCD strings for certain elements (invalid with respect to the UCD1+ standard) </span><span style="background-color: transparent;">in obstap columns definition.</span>
---++ Erratum Content
---++++ Invalid UCDs in Table 6 page 56: _TAP_SCHEMA.columns_
---+++++ Original Wording (Invalid UCDs)
   * *obs_publisher_did*: UCD = <em><span style="background-color: transparent;">meta.ref.uri;meta.curation</span></em> 
      * The problem being that <em>meta.curation </em>is a primary word (P) being used as secondary. _meta.ref.uri_ is indifferent (Q)
   * *publisher_id*: UCD = <em><span style="background-color: transparent;">meta.ref.uri;meta.curation</span></em> 
      * <span style="background-color: transparent;">Same as obs_publisher_did</span>
   * *o_stat_error* UCD =<em> <span style="background-color: transparent;">stat.error;phot.flux</span></em> 
      * The issue here being that the addition of _phot.flux_ is too specific for the usage.
---+++++ New Wording (correct UCDs)
   * *obs_publisher_did* <span style="background-color: transparent;">: UCD = _meta.ref.ivoid_ </span>
   * *publisher_id*: UCD = <em><span style="background-color: transparent;">meta.ref.ivoid</span></em>
   * *o_stat_error*: UCD = <em><span style="background-color: transparent;">stat.error</span></em>
---++ Impact Assessment
   * ObsCore clients normally use column names or perhaps utypes to identify data model members. The change of the UCDs proposed here should not impact them.
   * Clients not aware of ObsCore will profit from the proposed change; for obs_publisher_did and publisher_id, they will no longer produce diagnostics for invalid UCDs, and for o_stat_error they will not be mislead any more.
   * This change may rise Taplint warnings.
