Modular tool for constructing a link to a rights program from article information

摘要

A link to a rights advisor website can be constructed from article metadata by a non-programmer user by connecting together a chain of steps, each of which uses a pre-defined module or "widget" 108, which, in turn, performs a specific task. By selecting, configuring and arranging steps, different websites can be processed in different manners. However, since the modules are predefined, they cannot be changed and thus the overall process can be controlled to prevent problems with one program from affecting other programs. The modules may be constructed from Javascript code and receive input in the form of XML data 102. The system may provide the execution engine of the system 106 with means to test one or more modules before execution, for copyright clearance.
