A SOAP-Based Tool for User Feedback and Analysis
Simple Object Access Protocol (SOAP) is a new technology utilizing extensible markup language (XML) sent over the Internet via the Hypertext Transfer Protocol (HTTP). SOAP was used to implement a tool to elicit user feedback on a prototype web service developed at the Lister Hill National Center for Biomedical Communications, an R&D division of the National Library of Medicine (NLM). The service, called MyMorph, allows an end user to convert files in more than fifty different formats to the Portable Document Format (PDF). The MyMorph service uses client software running on the user's computer to send files via SOAP to a computer system at NLM called DocMorph, which converts them to PDF and returns the results to the user's computer. MyMorph can support document delivery, as well as file migration for electronic document preservation. To help determine its usefulness, the MyMorph software included an optional user survey that allowed users to provide feedback to the developers via SOAP. This paper describes how the SOAP-based survey was implemented, and analyzes the survey results.
