<-- Date accepted|rejected: 20NN-MM-DD --> RationaleIn the process of moving the DataLink-1.0 into the ivoa-std GitHub repo, it has been found an error in the example in §4.6 (page 26) (see DataLink issue #3). The error consists in a wrongref="primaryID" attribute linking a service descriptor PARAM
to a results table FIELD .
This erratum proposes to suppress the wrong ref attribute.
Erratum ContentThis Erratum proposes to replace, in §4.6 of DataLink - Version 1.0 the firstRESOURCE element of the example:
<RESOURCE type=”meta” utype=”adhoc:service” name=”this”> <PARAM name="standardID" datatype="char" arraysize="*" value="ivo://ivoa.net/std/DataLink#links-1.0" /> <PARAM name="accessURL" datatype="char" arraysize="*" value="http://example.com/mylinks" /> <GROUP name=”inputParams”> <PARAM name=”ID” datatype=”char” arraysize=”*” value=”” ref=”primaryID”/> </GROUP> </RESOURCE>with the following one: <RESOURCE type=”meta” utype=”adhoc:service” name=”this”> <PARAM name="standardID" datatype="char" arraysize="*" value="ivo://ivoa.net/std/DataLink#links-1.0" /> <PARAM name="accessURL" datatype="char" arraysize="*" value="http://example.com/mylinks" /> <GROUP name=”inputParams”> <PARAM name=”ID” datatype=”char” arraysize=”*” value=”” /> </GROUP> </RESOURCE>That is, removing the ref attribute and its value, that refer to a non-existent FIELD in the example itself.
Impact AssessmentThe proposed change doesn't impact any part of DataLink implementations since it simply amends an example fixing it.<--
