DDI 4 Sprint in Toronto, June 2014
Introduction
We started with the concept for a production workflow as designed in the previous sprint in Vancouver (figure 1) and identified a couple of issues (documented in the Wiki: IASSIST sprint, technical group). Because we were able to solve most of these issues during the sprint, this document focuses on only a subset of issues where the solution is important to document for subsequent work.
Out of our 11 issues, we selected one as our overall goal for this sprint: to produce a working prototype for the production workflow to prove the overall concept.

Joachim identified a method to roundtrip IDs from Drupal. This is an important preparatory step to actually shipping IDs forth and back. XMI allows the integration of custom attributes attached to any type of object
<ownedAttribute visibility="private" name="CustomLabel2" xmi:type="uml:Property" xmi:id="EAID_084B6228_A680_47fa_8985_F729C4CAD9D6" isDerivedUnion="false" isUnique="true" isOrdered="false" isDerived="false" isReadOnly="false" isStatic="false">
<type xmi:idref="EAID_7DF1F728_66C0_4376_A7EE_651E86DF2986"/>
<lowerValue xmi:type="uml:LiteralInteger" xmi:id="EAID_LI000015_A680_47fa_8985_F729C4CAD9D6" value="1"/>
<upperValue xmi:type="uml:LiteralInteger" xmi:id="EAID_LI000016_A680_47fa_8985_F729C4CAD9D6" value="1"/>
<defaultValue xmi:type="uml:LiteralString" xmi:id="EAID_LI000017_A680_47fa_8985_F729C4CAD9D6" value="QuestionnaireLabel2"/>
</ownedAttribute>

After substantial discussion of the production workflow (Vancouver version) we did some modifications to the design, documented in figure 2.

Handling updates in Drupal and EA
...
EA can version per package. XMI is used as transport format between EA and version control repository.

Drupal could use the version control repository as source for the own data base tables.
