Scientific data represents a significant portion of the linked open data cloud and scientists stand to benefit from the data fusion capability this will afford. Publishing linked data into the cloud, however, doesn't ensure the required reusability. Publishing has requirements of provenance, quality, credit, attri-bution and methods to provide the(More)
The Taverna workflow tool suite (http://www.taverna.org.uk) is designed to combine distributed Web Services and/or local tools into complex analysis pipelines. These pipelines can be executed on local desktop machines or through larger infrastructure (such as supercomputers, Grids or cloud environments), using the Taverna Server. In bioinformatics, Taverna(More)
The Taverna workflow management system is an open source project with a history of widespread adoption within multiple experimental science communities, and a long-term ambition of effectively supporting the evolving need of those communities for complex, data-intensive, service-based experimental pipelines. This paper describes how the recently overhauled(More)
Knowledge-intensive applications pose new challenges to metadata management, including distribution, access control, uniformity of access, and evolution in time. This paper identifies general requirements for metadata management and describes a simple model and service that focuses on RDF metadata to address these requirements.
Grid resources such as data, services, and equipment, are increasingly being annotated with descriptive metadata that facilitates their discovery and their use in the context of Virtual Organizations (VO). Making such growing body of metadata explicit and available to Grid services is key to the success of the VO paradigm. In this paper we present a model(More)
RAPID AND RADICAL CHANGE in almost every facet of society has brought in its wake community anxiety, suspicion and hostility. Current examples in Australia include the impact of globalisation, the introduction of the goods and services tax, and the actions of the banks in phasing out local branches. Even the health industry faces increased levels of public(More)
This paper presents the rules used within the Open PHACTS (http://www.openphacts.org) Identity Management Service to compute co-reference chains across multiple datasets. The web of (linked) data has encouraged a proliferation of identifiers for the concepts captured in datasets; with each dataset using their own identifier. A key data integration challenge(More)
While single-user computing via the Internet has established a powerful global link between people, it offers little to individuals working intensively and collaboratively with an array of tools, documents and materials in one physical space. This shortcoming in the everyday employment of Information Technology (IT) has prompted the architect-author to(More)
BACKGROUND Data discovery, particularly the discovery of key variables and their inter-relationships, is key to secondary data analysis, and in-turn, the evolving field of data science. Interface designers have presumed that their users are domain experts, and so they have provided complex interfaces to support these "experts." Such interfaces hark back to(More)
