Beth Plale Associate Professor School of Informatics and Computing Indiana University Metadata and Provenance Collection and Representation in eScience: Antecedent to Scientific Data Preservation There is significant attention today to the sharing of scientific data now and into the future. But scientific data is highly contextual. That is, to understand and use the data requires considerable contextual information. When sharing is between researchers that know one another, that context is conveyed verbally and through social clues. When the distance between researchers grows, the context must accompany the data in less ephemeral forms. In this talk I describe our efforts at the automatic collection of metadata and provenance for purposes of capturing context of scientific data. In particular we have developed the XMC Cat metadata catalog that actively collects and logs metadata during experiment execution. XMC Cat is a standalone web services persistent service that can work with back end storage resources to augment access to scientific data. The Karma provenance collection tool is the platform around which we are studying provenance collection in computer science ! applications and earth science applications. These two data sources provide critical information to form what we call the "preservation object", which encodes the contextual information needed to share scientific data. Biography Beth Plale is Director of the Data To Insight Center and is an Associate Professor of Computer Science in the School of Informatics and Computing Indiana University Bloomington. Professor Plale has a strong research interest in metadata and provenance of digital scientific data particularly for purposes of long term preservation and focuses on "the first mile" where collection is automatic and close to the generation source. Plale is deeply engaged in environmental and atmospheric science research and has substantive experience in developing stable and useable scientific cyberinfrastructure. _______________________________________________ Colloquium mailing list [email protected] https://secure.engr.oregonstate.edu/mailman/listinfo/colloquium
