Semantically Documenting Virtual Reconstruction: Building a Path to Knowledge Provenance

Semantically Documenting Virtual Reconstruction: Building a Path to Knowledge Provenance

The outcomes of virtual reconstructions of archaeological monuments are not just images for aesthetic consumption but rather present a scholarly argument and decision making process. They are based on complex chains of reasoning grounded in primary and secondary evidence that enable a historically probable whole to be reconstructed from the partial remains left in the archaeological record. Thi...

The Path to Virtual Machine Images as First Class Provenance

The scientific community’s increased exposure to cloud computing has led to increased familiarity with the machine virtualization technology that underpins the cloud. Efforts to define and implement provenance for the cloud are under way. In the meantime, however, an orthogonal idea, aimed at quickly facilitating repeatability and curation, has taken shape. This is the idea of using virtual mac...

Knowledge Provenance in Virtual Observatories: Application to Image Data Pipelines

Scientific data services are increasing in usage and scope, and with these increases comes growing need for access to provenance information. Our goal is to design and implement an extensible provenance solution that is deployed at the science data ingest time. In this paper, we describe our work in the setting of a particular set of data services in the area of solar coronal physics. The paper...

Semantically-Enabled Virtual Observatories

We are developing a semantic data framework for virtual observatories. A Virtual Observatory provides online location, retrieval, and analysis services to a variety of heterogeneous scientific data sources. We employ semantic technologies to integrate data and provide “intelligent” services such as ontology-enhanced search, analysis, and data visualization. Our specific initial deployments are ...
