  1. SIML A template language for an extensible data driven decision  support system to support policy making Presentation by Jordan Reese Slides adapted from Ren Bauer Supervised by Hye-Chung Kum

  2. Social workers needed a better way to extract useful information SIML: What’s it for? • Lots of data • Child Welfare • Food and Nutrition Services • Work First

  3. SIML: What’s it look like? ssw.unc.edu/ma

  4. SIML: How’s it work? • The SIML environment includes: • Templates • External files • Compilation engine • User writes a configuration file • SIML (XML based) • Specify template, dataset, variables, etc. • User runs compilation engine • Combines configuration and template files • Produces SAS/Internet output file • User opens output in a browser • Broker generates HTML from output and external files • Browser displays HTML to user

  5. SIML: How’s it work?

  6. Advantages • Extensibility • Adding new pages • Generating new views of existing data • Usability • Systems knowledge • Basic knowledge of SAS

  7. Future Work • Further Adaptability • Ease of integration • User Personalization • Adaptive Menus • More active support • Integration of policy data We’ve noticed a recent increase in your work first cases. Ashe county has experienced a sharp decrease since their implementation of policy WF-9000 in 2011Q1. Click herefor more details.

  8. The Project Now • Ren is working elsewhere for the summer • Big shoes to fill • Transition from old SAS to new SAS • Via compiling SIML files with Ren’s PHP engine • Writing SIML code and troubleshooting both the SIML code and PHP engine

  9. Challenges • Learning SAS, SIML, PHP • No prior experience • Understanding someone else’s code • Only a few hours a week to work on it • Some features not exactly right • Error in either the documentation or engine

  10. The Future • Goals: • Correctly produce HTML identical to that in the production version • Do this for Child Welfare, Work First, and Food and Nutrition Services • Ren has already done most of Child Welfare, except indexes, which is where the aforementioned bug lies

  11. At The Moment • Going through the PHP code trying to figure out why dropdown boxes are not displaying correctly. • Based on these findings, either edit PHP engine or SIML’s documentation • Still learning PHP and SAS as I go
