“…By implementing MOBY Central specifically for the PlaNet consortium, the relevance of discovered services could be greatly enriched for consortium members. Through the ongoing collaboration with my Grid, who have designed an extremely rich ontology for describing Web Services, this limitation of MOBY Central is being addressed, and the search and discovery mechanisms in future iterations of MOBY should be much richer and more focused (Lord et al, 2005).…”

The burden of noninteroperability between on-line genomic resources is increasingly the rate-limiting step in large-scale genomic analysis. BioMOBY is a biological Web Service interoperability initiative that began as a retreat of representatives from the model organism database community in September, 2001. Its long-term goal is to provide a simple, extensible platform through which the myriad of on-line biological databases and analytical tools can offer their information and analytical services in a fully automated and interoperable way. Of the two branches of the larger BioMOBY project, the Web Services branch (MOBY-S) has now been deployed over several dozen data sources worldwide, revealing some significant observations about the nature of the integrative biology problem; in particular, that Web Service interoperability in the domain of bioinformatics is, unexpectedly, largely a syntactic rather than a semantic problem. That is to say, interoperability between bioinformatics Web Services can be largely achieved simply by specifying the data structures being passed between the services (syntax) even without rich specification of what those data structures mean (semantics). Thus, one barrier of the integrative problem has been overcome with a surprisingly simple solution. Here, we present a nontechnical overview of the critical components that give rise to the interoperable behaviors seen in MOBY-S and discuss an exemplar case, the PlaNet consortium, where MOBY-S has been deployed to integrate the on-line plant genome databases and analytical services provided by a European consortium of databases and data service providers.

“…It has, however, been observed that bioinformatics web services have certain characteristics that can further hinder the process of their semantic annotation [2]. Since many services in the bioinformatics domain are developed on an as-needed basis, such web services typically have poor quality descriptions [3].…”

“…Such software can output poor quality WSDL files in which operations, parameters and datatypes are given meaningless identifiers. Also, as a result of their ad hoc creation, such web services can be deployed with little or no associated documentation [2]. The lack of an agreed upon data model in bioinformatics also means that such web services usually have weakly typed web service operation parameters [4].…”

Abstract. Semantic annotation of web services is achieved by associating parts of service interface descriptions to concepts defined in a semantic model, such as an ontology. Annotating web services with semantic metadata is currently a manual procedure that is conducted by human annotators. In practice, however, service annotation can be both timeconsuming and error-prone to implement on real-world web services. We have investigated this problem in the bioinformatics domain, where certain characteristics shared by many web services make them a difficult breed to annotate with semantics. By taking these characteristics into consideration, we present a probing-based technique that identifies upper and lower semantic bounds for the annotation of web service input parameters. The resulting bounds can serve as a useful starting point for human annotators and could help reduce the required effort in the semantic annotation process.

“…As a second, more general-purpose option, a semantic discovery facility called Feta [12] also offered natively as part of the Taverna distribution. Feta includes a semantic service registry that maintains annotated description of services, and can be searched using terms from a publicly available ontology.…”

Abstract. With the emergence of "service oriented science," the need arises to orchestrate various services to facilitate scientific investigation --that is, to create "science workflows." In this paper we summarize our findings in providing a workflow solution for the caGrid service-based grid infrastructure. We choose BPEL and Taverna as candidate solutions, and compare their usability in the full lifecycle of a scientific workflow, including service discovery, service composition, workflow execution, and workflow result analysis. We determine that BPEL offers a comprehensive set of primitives for modeling processes of all flavors, while Taverna provides a more compact set of primitives and a functional programming model that eases data flow modeling. We hope that our analysis not only helps researchers choose a tool that meets their needs, but also provides some insight on how a workflow language and tool can fulfill the requirement of scientists.
