GPSL: A Programming Language for Service Implementation
At present, there is a dichotomy of approaches to supporting web service implementation: extending mainstream programming languages with libraries and metadata notations vs. designing new languages. While the former approach has proven suitable for interconnecting services on a simple point-to-point fashion, it turns to be unsuitable for coding concurrent, multi-party, and interrelated interactions requiring extensive XML manipulation. As a result, various web service programming languages have been proposed, most notably (WS-)BPEL. However, these languages still do not meet the needs of highly concurrent and dynamic interactions due to their bias towards statically-bounded concurrency. In this paper we introduce a new web service programming language with a set of features designed to address this gap. We describe the implementations in this language of non-trivial scenarios of service interaction and contrast them to the corresponding BPEL implementations. We also define a formal semantics for the language by translation to the join calculus. A compiler for the language has been implemented based on this semantics.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
