New in OIA Data Viewer 24B

We’ve been having fun with the various tools known as the OIA Data Viewer. As some may recall it started out as a simple tool to view the projectDataModel.xml file in graphical format, a little like the old v10 entity viewer. The OIA Data Viewer actually uses some of the same third-party components.

As you all probably know, in spite of it’s name, the projectDataModel.xml file does not contain all the …data model. It only contains a subset that meets certain conditions (mapped or named or given a value list for example). So the OIA Data Viewer was extended to get all the other attributes that are in the individual XGEN files for Excel and Word documents.

Once that was done, a decision was made to also read the Enumerations XML file to get the Value Lists, and gradually over time the OIA Data Viewer has added Decision Service Reference files (REF Files) and Custom Functions (new in this version). Export of these diagrams (fully customizable in terms of colours, style and so on is available to PDF, SVG and Excel. It can also read Decision Service JSON files and can display the structure of the interview if you have one.

The second set of “things that might be useful” is the Test Case Creator. It is designed to help create lots of iterations of values in Test Cases, so that you can spend more time testing and less time copying and pasting in Excel. In 24B, support has been extended to entities and entity instance identifiers and it comes with a sometimes lucid Help File.

Right now we use it purely for our own customer work, but one day we might actually release it for real. We’ve learned a massive amount about how OPM manages the policy modeling process, how the Excel Word and Excel plugins work, and what public code is available to leverage.

As we head towards 24C and 24D, the big goal is to now go backwards 🙂 – specifically, if you can draw an entity diagram, can the OIA Data Viewer create a project from that diagram – adding all the entities and attributes that you have drawn. This sort of tool has always been one of the most asked for from the business.

We’ll see. There is a lot going on at the moment and another book is in the works, so progress will not be too rapid. But we’re on it!
