The Web Mashup Scripting Language Profile

The Web Mashup Scripting Language (WMSL) enables an end-user working from his browser, e.g. not needing any other infrastructure, to quickly write mashups that integrate any two, or more, web services on the Web. The end-user accomplishes this by writing a web page that combines HTML, metadata in the form of mapping relations, and small piece of code, or script. The mapping relations enable not only the discovery and retrieval of the WMSL pages, but also affect a new programming paradigm that abstracts many programming complexities from the script writer. Furthermore, the WMSL Web pages or scripts those disparate end-users write can be harvested by crawlers to automatically generate the concepts needed to build aligned ontologies. These aligned ontologies are comprised of the local semantics of web services' data models, extentions of context ontologies (middle ontologies), and links, or mappings, between the data models and also to the middle ontologies.
