Tetherless World Constellation

Sessions

I would like to lobby for submissions to:

http://sites.agu.org/fallmeeting/scientific-program/session-search/542
Semantic Solutions and Linked Data for Science

and

http://sites.agu.org/fallmeeting/scientific-program/session-search/536
Metadata in Modeling Workflows

I am covening both of them.

I think our provenance and workflow work fits very well into 536
and i think our sesf / spcdis / s2s / semantically-enabled pretty much anything fits well into 542.

part of the AGU setting is that it is useful to get a number of contributions to one particular session so that that session can get an oral session. If there are too few submissions, then a session only gets posters. I would like to see both of the sessions i am convening get oral sessions so i am lobbying. also from a collaborator perspective, i will definitely be in those sessions to help answer questions or refer people.
If the material you are considering fits elsewhere, definitely submit elsewhere but if it fits here, definitely consider submitting here.

There's a new session called Science on Drupal that would be a good target for the website work.

1) Advances in Multi-disciplinary Information Systems
2) Semantic Solutions and Linked Data for Science
3) Software Reuse and Open Source Software in Earth Science

...Topics may include: role of OSS in software reuse; designing for reuse; reuse of web services, service oriented architecture; ...
4) Real Use of Open Standards and Technologies
...We invite demonstrations of ready-to-use applications for data discovery, integration and visualization using OpenSearch, OGC-based services and encodings,...

Invited to AGU Session IN04: Architectural Components for Science Data Repositories and Archives

Information Model Driven Semantic Framework Architecture and Design for Distributed Data Repositories (Peter Fox and the SeSF team)

In Earth and space science, the steady evolution away from isolated and single purpose data 'systems' toward systems of systems, data ecosystems, or data frameworks that provide access to highly heterogeneous data repositories is picking up in pace. As a result, common informatics approaches are being sought for how newer architectures are developed and/or implemented. In particular, a clear need to have a repeatable method for modeling, implementing and evolving the information architectures has emerged and one that goes beyond traditional software design. This presentation outlines new component design approaches bases in sets of information model and semantic encodings for mediation.

Invited to IN29. Semantic Solutions and Linked Data for Science

Facilitating Next Generation Science Collaboration: Respecting and Mediating Vocabularies with Semantics in Ecosystems Assessments.

Peter Fox, Andrew Maffei and the ECOOP team.

A newly funded initiative is developing and deploying an integrated ecosystem assessment (IEA) system using an information science and semantic technologies. The intention is to advance the capacity of an IEA to provide the foundation for synthesis and quantitative analysis of natural and socio-economic ecosystem information to support ecosystem-based management. In particular, the initiative is create the capacity to assess the impacts of changing climate on two large marine ecosystems: the northeast U.S. and the California Current. These assessments will be essential parts of the science-based decision-support tools used to develop adaptive management measures. Enhanced collaboration is required to achieve these goals: interaction and information sharing within and among diverse data providers, analysis tool developers and user groups that constitute the broader coastal and marine ecosystem science application community. This presentation indicates how semantic solutions are fundamental to this initiative.

The lack of development environments for interdisciplinary research conducted on large-scale datasets hampers research at every stage. Projects incur large startup costs as disparate infrastructure is assembled; experimentation slows when software components and environment are mismatched for specific research tasks; and findings are disseminated in forms that are hard to examine, learn from, and reuse. Behind these problems is a common cause — the lack of good tools. When large, heterogeneous and distributed data is added to the equation, further frustration, at the least, ensues. As a result using existing platforms, the programmers of 21st century interactive visualizations are reduced to working in the same fashion with the same tools as 20th century database programmers. Our contribution is to bring the tools of digital artists to bear on the aforementioned data analysis and visualization challenges. Here we report on the current state of progress in adapting Field for large-scale, web-based scientific data analysis and visualization with an emphasis on Linked Open Data and especially the current data hosted by RPI.

TITLE: A Semantic Representation of Product Quality and Evidence for Satellite Data
PRESENTATION TYPE: Assigned by Committee (Oral or Poster)
CURRENT SECTION/FOCUS GROUP: Earth and Space Science Informatics (IN)
CURRENT SESSION: IN31. The Challenge of Data Quality in Earth Observations and Modeling
AUTHORS (FIRST NAME, LAST NAME): Stephan Zednik1, Gregory G Leptoukh2, Peter Arthur Fox1, Christopher Lynnes2, Patrick West1, Suraiya P Ahmad2
INSTITUTIONS (ALL): 1. Tetherless World Constellation, Rensselaer Polytechnic Institute, Troy, NY, United States. 2. NASA Goddard Space Flight Center, Greenbelt, MD, United States.
ABSTRACT BODY: There is growing interest within the broad research community to leverage satellite data for cross-disciplinary analysis and to make use of the data in ways unanticipated by the data provider. Poorly documented or publicized product quality information is a significant barrier to the successful or confident integration of satellite data for many users. Researchers seek clearly and consistently characterized product quality to facilitate assessment of product fitness-for-use. We argue that data product discovery mechanisms should be augmented with facilities to present product quality information; targeted to provide a condensed and clear view of product quality and to support comparison with quality of other like products.

We propose a method of provisioning product quality into aspects (e.g. completeness, consistency, accuracy, bias) and displaying computed and inferred facts as evidence to help characterize one or more aspects of the product quality. We describe the product quality ontology developed to facilitate this characterization of product quality. Finally, we illustrate the utility of this approach by showing how we have applied it to presenting product quality for the NASA MODIS Aerosol data product within a prototype implementation of the NASA Giovanni Data Access and Analysis Tool.

TITLE: OPeNDAP Hyrax: An extensible data access framework within the Earth System Grid Federation
PRESENTATION TYPE: Assigned by Committee (Oral or Poster)
CURRENT SECTION/FOCUS GROUP: Earth and Space Science Informatics (IN)
CURRENT SESSION: IN15. Envisioning Improvements for Earth Science Data Access
AUTHORS (FIRST NAME, LAST NAME): Patrick West1, Peter Arthur Fox1, James Gallagher2, Nathan Potter2, Daniel Holloway2, Stephan Zednik1
INSTITUTIONS (ALL): 1. Tetherless World Constellation, Rensselaer Polytechnic Institu, Troy, NY, United States.
2. OPeNDAP, Narragansett, RI, United States.
ABSTRACT BODY: There is an ever-growing need for the researcher to not only have access to research data, but to also execute aggregation and server-side analysis functionality against this data remotely, and to have this new data product available for further analysis and manipulation. This reduces the burden on the researcher of retrieving and maintaining large data files and streamlines common, repetitive pre-processing tasks. It also helps to standardize common pre-processing tasks by providing them as a service, maintained and tested by the data publisher.

OPeNDAP Hyrax is a multi-tier software framework and data access server that implements not only the DAP (Data Access Protocol) specification, but is also an extensible, modular framework that provides the data provider and researcher with the ability to perform on-demand server-side analysis, aggregation and manipulation of the data. The framework supports the installation of dynamically loaded modules that may be developed to add support for new data formats, data product responses, or server-side analysis operations.

This presentation covers the use of OPeNDAP Hyrax in the Earth System Grid Federation for access to climate research models and observations in order to meet the needs of the World Climate Research Programme (WCRP).

Title: Next Generation Environmental Informatics as exemplified by the Tetherless World Semantic Water Quality Portal
Section: earth and space science informatics
Session: in29 semantic solutions and linked data for science
Authors: Wang, P., Zheng, J., Fu, L., Patton, E., Lebo, T., Ding, L., Luciano, J.S., and McGuinness, D.L.
Orgs: RPI
Abstract: The need for flexible, extensible environmental monitoring is increasing. We are investigating semantically-enabled approaches that can support dynamic environmental informatics portals. We leverage open data from multiple sources and use semantic tools to consume, integrate, analyze, and present environmental data. Our demonstration domain is in water quality. We utilize a simple water quality ontology to help integrate data and identify regulatory thresholds for contaminant levels according to various federal and state agencies. Users can use the portal to identify polluted water sources and polluting facilities. The backend reasoner is using simple description logic supported recognition queries. The portal allows investigation by geographic region, regulation perspective and contaminant. It also maintains extensive provenance information so that it may provide provenance-aware search, discovery, and reasoning.

CONTROL ID: 1211229
TITLE: Semantic Representation of Temporal Metadata in a Virtual Observatory
PRESENTATION TYPE: Poster Requested
CURRENT SECTION/FOCUS GROUP: Earth and Space Science Informatics (IN)
CURRENT SESSION: IN29. Semantic Solutions and Linked Data for Science
AUTHORS (FIRST NAME, LAST NAME): Han Wang1, Eric A Rozell1, Patrick West1, Stephan Zednik1, Peter Arthur Fox1
INSTITUTIONS (ALL): 1. Rensselaer Polytechnic Institute, Troy, NY, United States.
ABSTRACT BODY: The Virtual Solar-Terrestrial Observatory (VSTO) Portal at vsto.org provides a set of guided workflows to implement use cases designed solar-terrestrial physics and upper atmospheric science. Semantics are used in VSTO to model abstract instrument and parameter classifications, providing data access to users without extended domain specific vocabularies. The temporal restrictions used in the workflows are currently possible via RESTful services made to a remote system with access to a SQL-based metadata catalog.

In order to provide a greater range of temporal reasoning and search capabilities for the user, we propose an alternative architecture design for the VSTO Portal, where the temporal metadata is integrated in the domain ontology. We achieve this integration by converting temporal metadata from the headers of raw data files into RDF using the OWL-Time vocabulary.

This presentation covers our work with semantic temporal metadata, including: our representation using OWL-Time, issues that we have faced in persistent storage, and performance and scalability of semantic query. We conclude with discussions of the significance semantic temporal metadata has in virtual observatories.
