Capturing Provenance in the Wild
نویسندگان
چکیده
All current provenance systems are “closed world” systems; provenance is collected within the confines of a well understood, pre-planned system. However, when users compose services from heterogeneous systems and organizations to form a new application, it is impossible to track the provenance in the new system using currently available work. In this work, we describe the ability to compose multiple provenance-unaware services in an “open world” system and still collect provenance information about their execution. Our approach is implemented using the PLUS provenance system and the open source MULE Enterprise Service Bus. Our evaluations show that this approach is scalable and has minimal overhead.

StudyCapture myopathy in red deer and wild goat
This syndrome is a shock-like hyper metabolic myopathy triggered in susceptible animals by stress. Capture myopathy (C.M.) is a commonly occurring condition in mammals following trapping and transportation. In this case 12 to 24 hours after transportation of red deer (Cevus elaphus) and wild goats (Capra ibex) clinical signs such as: muscular tremor, ataxia, recumbency, hyperthermia, tachyca...
متن کاملThe essential oils compositions of Iranian Oregano (Origanum vulgareL.) populations in field and provenance from Piranshahr district, West Azarbaijan province, Iran
Objective: Origanum vulgare L. is rarely cultivated in Iran but it is the only species of the Origanum genus growing wild in this country. O.vulgare L. is widely spread all over the country. In this study, parameters of content, composition and antioxidant activity of the essential oils of domestic and wild Iranian Oregano populations were compared with one another. Materials and Methods: The...
متن کاملOn the Use of Abstract Workflows to Capture Scientific Process Provenance
Capturing provenance about artifacts produced by distributed scientific processes is a challenging task. For example, one approach to facilitate the execution of a scientific process in distributed environments is to break down the process into components and to create workflow specifications to orchestrate the execution of these components. However, capturing provenance in such an environment,...
متن کاملThe Aspect-Oriented Architecture of the CAPS Framework for Capturing, Analyzing and Archiving Provenance Data
With aspect-oriented programming techniques, modularity may be achieved via separating cross-cutting concerns. Data provenance can be considered as a crosscutting concern: code for collecting provenance data is usually scattered across various places in a software system. Aspect-oriented programming allows to seamlessly integrate cross-cutting concerns into existing software applications withou...
متن کاملDecoupling Provenance Capture and Analysis from Execution
Capturing provenance usually involves the direct observation and instrumentation of the execution of a program or workflow. However, this approach restricts provenance analysis to pre-determined programs and methods. This may not pose a problem when one is interested in the provenance of a well-defined workflow, but may limit the analysis of unstructured processes such as interactive desktop co...
