A working draft for TAPRegExt 1.1 is available on volute: https://volute.g-vo.org/svn/trunk/projects/registry/TAPRegExt

Proposed Errata

Query in 10.7 "Records from Registry"

(This erratum is obviated by the soon-to-be version 1.1 of the standard text)

Suggested Text

The exampe in section 10.7, "Records from Registry" should read

SELECT ivoid FROM rr.resource
RIGHT OUTER JOIN (
  SELECT 'ivo://' || detail_value || '%' AS pat
  FROM rr.res_detail
  WHERE detail_xpath='/managedAuthority' 
    AND ivoid='ivo://cds.vizier/registry') 
  AS authpatterns
ON (1=ivo_nocasematch(resource.ivoid, authpatterns.pat))

Rationale

As values in res_detail are no longer case-normalized (as they had been when the example query was written), the query as given in the REC-1.0 will not yield results for mixed-case authorities (and as it happens, the authorities in the examples are all mixed case). The proposed new query works regardless of authority case.

Impact assessment

As no normative text is changed, implementations are not concerned. Persons trying the example queries will be spared debugging.
