1 The Role of Standards and Open Source Software in Student Information Systems Jerald Bracken April 4, 2012 AACRAO SPEEDE Committee

2 Open Source: software whose source code is published and made available to the public, enabling anyone to copy, modify and redistribute the source code without paying royalties or fees Development Process is Open Favors Agile, Pragmatic Development Active Community Support Commitment to Standards Innovation Higher Quality Software

3 Examples: Linux Operating System Apache Web Server Java Language & Virtual Machine Tomcat J2EE Application Server Glassfish J2EE Application Server MySQL Database Moodle Course Management System uportal jasig Portal Framework CAS jasig Central Authentication Service Kuali Student Modular Student System

4 Kuali Student (KS) is a community-source, next-generation information system designed to meet the business needs of students, faculty and institutions throughout the academic lifecycle. The software is being incrementally produced by a dedicated community of international higher education partners and distributed through the Open Source license. It achieves a rich user experience through user-centric design and offers a modular, scalable system through serviceoriented architecture. Because of this modular nature, it can be integrated with legacy and enterprise systems to meet your institution s current business needs. With its service oriented architecture, Kuali Student can be configured for how you do business today and how you'll want to do business tomorrow.

7 Things I liked about the Kuali Student Project: Early commitment to AACRAO SPEEDE Standards Early innovative thinking about how student systems should be built Commitment to Java and J2EE standards Commitment to web services Promise of an open development process But I worried about the sustainability of this effort

8 But... Not as Open as I would have hoped Pay to Play, Consortium development Design and Development of Infrastructure components like Rice (middleware) and authentication and authorization models consumed much of the early development effort Work is not to the point that we can see the proof of their commitment to AACRAO SPEEDE Standards Not to the point that we can see the degree of innovation that has made it into the project

9 But... Taking much longer and consuming more resources than I would have expected. Is this because of politics or prolonged discussions over governance, funding, architecture, project approaches, etc.? Did they choose a waterfall development methodology over an agile approach? Or, have I grossly underestimated the scope of work? Interoperable Modularity is very difficult to achieve in reality Web Services as a mechanism to provide interoperability is very difficult to do in reality The commitment of the Kuali membership has been nothing short of phenomenal

10 Is there Room for another Open Source Student System? Depends: Expertise Technical and Functional Community of passionate developers with time and resources Shared Vision Modules Modularity implies interoperability

11 How would I approach it? Open, vetted data model with build scripts and data conversion examples. A reasonable, coherent data model will drive the first round of innovation Early validation of the data model will pay dividends later on in the project. Part of the data model validation process is presentation prototyping. In some frameworks the prototypes become the real product as functionality gets added. Agile, iterative, pragmatic development. Interoperability through Data model conventions: Rails naming conventions Codes tables Business Rules (Rules Engine) Attribute Tables for optional and perhaps multiply-occurring data items Trees and Lists

12 Module Interfaces or Modular Interoperability Web services REST vs. SOAP, JSON vs. XML Where tighter, more complex interactions are needed or performance is an issue, more direct interactions must be provided for. API Design becomes important from the beginning?

13 Balance between Converging Business Practices vs. Flexibility in Configuring for Divergent Business Practices Easily Extended Source code has to be readily available, understandable and modifiable. Student Systems are Strategic to the mission of every institution Better said, some aspect or component of your student system will be directly related to the mission of your institution. You will need to modify those components to meet your mission.

17 Is There Room? YES. It is just a matter of will. Do we have the will?
