Beyond a Data Portal: A Collaborative Environment for the Deep Carbon Science CommunitiesHan Wang, Yu Chen, Patrick West, John Erickson, Xiaogang Ma, and Peter FoxRensselaer Polytechnic Institute 110 8th St., Troy, NY, 12180 United States

Semantic Representation of Information and Data in DCO Knowledge BaseDeep Carbon Observatory (DCO) is a decade-long scientific endeavor to understand carbon in the complex deep Earth system. Thousands of DCO scientists from institutions across the globe are organized into communities representing four domains of exploration: Extreme Physics and Chemistry, Reservoirs and Fluxes, Deep Energy, and Deep Life. Cross-community and cross-disciplinary collaboration is one of the most distinctive features in DCO's flexible research framework.

In order to expedite research collaboration between DCO scientists and communities, the DCO Data Science team developed an infrastructure that integrates multiple open source software including Drupal, CKAN, VIVO, Handle, etc. This infrastructure not only serves as a registry and a repository of DCO resources such as datasets, documents, images, and videos, it also formulates a rapidly growing knowledge base that interconnects people, organizations, publications, activities, locations, and other entities of research interest in DCO communities to enable better browsing, searching, visualizing, and reporting.

DCO CommunityGlobal community of ‘Carbon scientists’ contributing to theDeep Earth Computer (data legacy) comprising:• Global Earth Mineral Laboratory• Global Inventory of Deep Fluids• Global Volcano Gas Emissions• Global Census of Deep Microbial

Life• State of High Pressure and

Temperature Carbon and Related Materials

• Global Inventory of Diamonds with Inclusions

DCO Statistics:• Over 4,800 people across 575

organizations.• Over 2,100 publications.• Over 210 projects including field

studies.• Over 1,600 research topics.• Over 130 datasets.• Over 590 research locations.

DCO Knowledge Base Infrastructure

Abstract

DCO Resources (e.g. datasets, documents, images, videos, etc.) stored using CKAN Repository(data.deepcarbon.net)

All resources receive a unique handle, a DCO-ID(dx.deepcarbon.net)

Semantic representation of information stored and maintained in VIVO, a Knowledge Graph(info.deepcarbon.net)

Experience

We take heterogeneous data and information from multiple different science domains across different organizations and organize them into a knowledge graph with over 550,000 triples.

We take the raw data, have users augment that with additional information and context, link the data together, then present it to the user from the knowledge base.

VIVO - represents academic research communities• Every person, organization, or other data entity in

VIVO has a unique identifier• VIVO enables the discovery of research and

scholarship across disciplines at one institution or across many

• Records are both human-readable and machine-readable

• VIVO Extension - we’ve extended (yes, ontologies) VIVO to the science network – datasets, instruments, sites, etc.
