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.

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.

After some deliberation, we decided to start with option 1 and make all changes in Drupal only. This would help us to start with a first prototype soon but would still allow as to additionally implement one or both of the other options. Fro Anchor_GoBack_GoBackm From a long-term perspective one single repository (option 3) would be desirable. Some tasks might be easier to archive in EA, so option 2 will be subject to further evaluation. At the moment we might not have enough development resources for option 2 and 3.
