Using Specimen Data in Scientific Workflow Environments to Connect to Metadata Archive and Discovery Services in Environmental Biology CJ Grady, J.H. Beach, A. Stewart, J. Cavner University of Kansas Biodiversity Institute

Geospatial Metadata Describes – What it is – What it looks like – Who assembled it – When it was collected – Etc

EML Ecological Metadata Language – XML Schema – Open Source – Community Driven – Describes ecological data Occurrence Data Climate Layers Species Ranges

Narratives Transformation of metadata into a story that is appropriate for the intended audience Same metadata can be used to create narrative for: – Scientists – Undergrads – K-12 students

Narrative Example

DataONE – Distributed system for: Queries Data replication – Initially supports EML

Study of Experiment Reproducibility Ellison, Aaron Repeatability and transparency in ecological research. Ecology 90.

There is a Solution!

Process Metadata Data about the process used Descriptive and prescriptive Documents process used to generate data / metadata – Quality control – SDM experiments – RAD experiments

Capabilities Reproducibility – Actions are documented Transparency – Experiments can be evaluated and validated Publishing – Metadata can be published along with results

What we have done EML for all of our Species Distribution Modeling services Simple process metadata – Documents how an experiment is ran through our cluster including what versions of software – Also describes what web services would be called to execute the experiment again

What we have done Clients – Python library – VisTrails – QGIS

What we are doing Publishing EML to a repository Client extensions Extending process metadata – HTTP message – XPath

Process Metadata Extensions HTTP Message – Documents any web resource call over HTTP XPath processing

What we will do next Use standard APIs to communicate with DataONE Continue to search for standard process metadata and include it whenever possible Contribute process metadata extensions back to the community Add additional conditional analysis elements to the schema (JSON, etc)

Reproducibility Simple process metadata EML process metadata extensions Lifemapper client EML reader

Transparency EML for all service objects Descriptive process metadata

Publishing Aid Client access to public data / metadata catalogs Publish buttons

Lessons Learned Had success starting with narrow, specific, process steps and generalizing them – Calls to our web services expanding to any HTTP call Easy to get carried away with all of the possibilities
