Several content management applications, both open and proprietary, have been created for undergraduate-level institutions. The SOM had special requirements. All first- and second-year students attend the same courses at the same time. Each course typically is taught by a number of different professors and clinicians, rather than one instructor. According to Hitlin, if customization was going to be a large part of the project, the CMS committee reasoned, why not go with an open-source version so that, at least, the code would be free? That way, the SOM could devote its limited resources to development and implementation.

"[The SOM] did look at commercial providers but felt that these commercial systems werent geared toward [a] graduate-level school. They realized they would have to do a custom solution no matter what," Thangavelu said. Given that, an open application seemed a very sound choice.

The CMS committee began to look at open-source projects in earnest, Hitlin said. It appraised Bricolage, Mason and OpenCMS but deemed them not quite right. Plone soon came to the forefront.

Plone is an open-source CMS built on Zope, an object-oriented application server written in the Python programming language. The Chapel Hill area has an active Plone user group, which was an advantage. Since the SOM was in the process of building up its developer staff after a few cutbacks, the committee believed it would not be difficult to find people with Plone skills in the area.

Thangavelu and a few Cignex colleagues were virtual team members in charge of development. They sent the SOM a series of alpha releases beginning in June 2005, and regression testing began.

Thats when the project ran smack into a major hardware problem. In the test environment, the application ran on an inexpensive Linux blade server and performed well, according to Hitlin and Thangavelu. But the project team got an unpleasant surprise when it installed the application on one of the SOMs Sun Microsystems Solaris SPARC boxes.

"As soon as we installed the application locally, we saw significant latency—10 seconds to load a page, where it had been 1 second in the development environment. It turned out the SPARC hardware doesnt run Python efficiently," Hitlin said.

Cignex advised the SOM to run the open Plone application on inexpensive Linux boxes, which would run a reasonable $2,000 to $3,000 each. But, according to Hitlin, the SOMs system support group was accustomed to supporting the Sun Solaris architecture and was reluctant to add a new platform to the mix.

"Our systems people didnt want to bring in something completely new and unfamiliar. On any large-scale project, you have to compromise. We chose to migrate to the Sun x86 architecture, which was new but more familiar to them," Hitlin said.

During June and July of 2005, the team dealt with last-minute bug fixes and user training, which turned out to be trivial, according to Hitlin and Thangavelu. The faculty members intuitively understood the user interface and took charge of updating their course materials with ease. But having lost time to the hardware snafu and software issues, the project came down to the wire. The first-year students were due to arrive for orientation the first week in August.

"It was a month later than our target date. There was a lot of stress, but we got it up and running just in time, three days before the students arrived on campus," Hitlin said. Both students and faculty immediately took to the application, soon demanding more—the price of all flourishing projects.

Both Hitlin and the UNC-CH are now converts to open source. The undergrad School of Arts and Sciences is implementing Plone, as is the UNC-CH hospital.

"Being part of the open-source community has been a big positive for us," Hitlin said.
