· DSTU document updates
o Review status of our DSTU QA review tasks and work on remaining updates
o Rob went through the glossary – removed entries fixed capitalizations
o Required - is the only place that using the term blank – blank is not the right term – null value is really what we mean – we are not using this in the HL7 conformance sense – we are using required in our overlap table – so remove entries for blank and required glossary entry
o Not permitted – this is for v3 messaging – remove
o Null – leave in
o There seem to be lot of glossary entries that are is explaining a lot of general HL7 items – do we need all this in the glossary?
o Choice – is lower case in v3 – update the document – does TermInfo need to define all the terms even if only mentioned once in the document? Delete entry about the choice due to specialization, as that is only used in the glossary entry of choice
o Coding and terminologies – is only in one place as header – we do have definitions for both elsewhere – remove
o Concept – use the HL7 definition from Core Principles
o Terminology – need to do more research on – the current definition here is not quite right – Daniel found the ISO definition, though it is not very extensive
o Terminology Server – server actually provides the vocabulary following the rules of the underlying terminology
Riki drops off the call at 10 AM EDT.
o We finished discussing the glossary entries for "terminology" and "terminology server". We now have the ISO 1087 definition for "terminology", plus the additional TermInfo note. Jos is going to write a further explanation of "terminology" vs. "vocabulary" and we'll look at that next week and see which definition we prefer to use.
o Rob will see if he is able to find (without spending too much time) a reasonable definition for "terminology server" and we can look at it next week - if not, we'll drop that entry.
o We discussed whether to reinstate the entry for "Version 3 Guide" as it's referenced 8 times elsewhere in the glossary, but decided to leave it out.
o Rob will check about removing the comments for ballot item #198 for the "vocabulary binding" entry (we should be OK to do that). There is also link to Core Principles in the 2014 ballot, and we should update that.
o We looked at and discussed the CDA R2 example that Rob added as Example 6 in 1.8.6.3.2.3. We decided to include only one example in this section (removed "mammography requested"). The numbering for the subsequent examples needs to be adjusted. We will keep the color coding from XML Spy in the example, as it helps with readability.
The call was adjourned at 10:30 AM EDT.
