Facilitating and Improving Environmental Research Data Repository Interoperability
Environmental research data repositories provide much needed services for data preservation and data dissemination to diverse communities with domain specific or programmatic data needs and standards. Due to independent development these repositories serve their communities well, but were developed with different technologies, data models and using different ontologies. Hence, the effectiveness and efficiency of these services can be vastly improved if repositories work together adhering to a shared community platform that focuses on the implementation of agreed upon standards and best practices for curation and dissemination of data. Such a community platform drives forward the convergence of technologies and practices that will advance cross-domain interoperability. It will also facilitate contributions from investigators through standardized and streamlined workflows and provide increased visibility for the role of data managers and the curation services provided by data repositories, beyond preservation infrastructure. Ten specific suggestions for such standardizations are outlined without any suggestions for priority or technical implementation. Although the recommendations are for repositories to implement, they have been chosen specifically with the data provider/data curator and synthesis scientist in mind
Darwin Core: An Evolving Community-Developed Biodiversity Data Standard
Biodiversity data derive from myriad sources stored in various formats on many distinct hardware and software platforms. An essential step towards understanding global patterns of biodiversity is to provide a standardized view of these heterogeneous data sources to improve interoperability. Fundamental to this advance are definitions of common terms. This paper describes the evolution and development of Darwin Core, a data standard for publishing and integrating biodiversity information. We focus on the categories of terms that define the standard, differences between simple and relational Darwin Core, how the standard has been implemented, and the community processes that are essential for maintenance and growth of the standard. We present case-study extensions of the Darwin Core into new research communities, including metagenomics and genetic resources. We close by showing how Darwin Core records are integrated to create new knowledge products documenting species distributions and changes due to environmental perturbations
Simulated Annealing of Two-Dimensional Plant Canopies
Introduction The spatial arrangement of leaves in a plant canopy is governed by a number of factors such as radiative and diffusive couplings and architectural support. Concentrating on how the plant's canopy structure affects its carbon balance through its efficacy in trapping radiation, the aim of this research is to investigate nearoptimal arrangements of leaves using an optimizing simulation technique. A Monte Carlo simulation method called simulated annealing is being developed to perform the optimization. Leaves are modelled as line segments which join points on a regular two-dimensional lattice. A net carbon balance is computed for a given configuration of leaves as the sun transcends a number of sky sectors. To improve a given leaf configuration, a Poster presented at ESA95 -- Ecological Society of Australia Open Forum & Symposium, Hobart, 1995. small change is made to it which is then considered to be an improvement based on
DataONE Member Node Implementation Workshop
Workshop at Open Repositories 2014, Helsinki, Finland, June 9-13, 2014Workshops and TutorialsThis one-day workshop will a) provide a brief overview of the Data Observation Network for Earth project (DataONE; http://dataone.org), b) explain the benefits for groups and institutions of collaborating with DataONE as a Member Nodes, c) present different ways to participate as a Member Node, d) discuss the process of becoming a Member Node, and e) demonstrate how to use the DataONE web services to access content from client applications. By the end of the workshop, participants will understand the design of DataONE, the services that DataONE provides to its Member Nodes and the users of those Member Nodes, and the technical information needed to establish a Member Node at their organization.
Intended Audience: Information managers and technical staff at organizations that are interested in becoming DataONE Member Nodes or that have started the process of becoming a DataONE Member Node.Wilson, Bruce (University of Tennessee, Knoxville, TN, USA)Koskela, Rebecca (University of New Mexico, Albuquerque, NM, USA)Vieglais, David (University of Kansas, Lawrence, KS, USA)Jones, Chris (University of California, Santa Barbara, CA, USA)Budden, Amber (University of California, Santa Barbara, CA, USA)Moyers, Laura (University of Tennessee, Knoxville, TN, USA
