---++ Datalink-1.0 Erratum 1: RESOURCE type value

Author: Markus Demleitner

Date last changed: 2017-11-22

Date accepted: 2018-02-22

---+ Erratum content

In section 3.2.3, in the first line of the example, [[http://ivoa.net/documents/DataLink/20150617][Datalink REC-1.0]] says

=<RESOURCE type="service"...=

This must be replaced with

   =<RESOURCE type="meta"...=


In section 4.4, in line 18 of the example, Datalink REC-1.0 says

   =<RESOURCE type="service"...=

This must be replaced with

   =<RESOURCE type="meta"...=


---+ Rationale

During the development of Datalink, it was discovered that the type
attribute of the VOTable RESOURCE element only admits a controlled
vocabulary.  The previous proposal to have type="service" for datalink
service definition blocks was then retracted.  Instead, conventional
type="meta" blocks are to be used.

In the editing process, two examples for the previous proposal were
accidentally left in the text.  This erratum corrects this oversight.

---+ Impact assessment

There should be no impact, except to reduce possible confusion of
implementors.  No normative text is changed, and even if someone had tried
to implement based on the erroneous examples, they would have yielded
invalid VOTables, and thus their services would have been flagged
invalid anyway.
