• Summary
3
A 10-year (2009-2019) initiative to intensify global attention and scientific effort in the burgeoning field of deep carbon science

• Faculty, staff and students from the Tetherless World Constellation (TWC) at Rensselaer Polytechnic Institute (RPI)
• Responsible for– DCO Architecture and technology infrastructure– DCO Computer Cluster– The Deep Carbon Virtual Observatory DCvO
Deep Carbon Observatory – Data Science

Deep Carbon Virtual Observatory
Scientists – actually ANYONE - should be able to access a global, distributed knowledge base of scientific data and information that:• appears to be integrated• appears to be locally available • is in a language (written, programming, or science)
that is understandable and can be sharedData intensive – volume, complexity, mode, scale,
heterogeneity, … in an OPEN WORLD
6
Deep Carbon Virtual Observatory
• A vision of the DCvO:– A conceptual model of the interplay between data, people,
publication, instruments, models, organizations, etc.– Identify, annotate and link all key entities, agents and activities – A repository for datasets and associated metadata– Unique and powerful data and metadata visualization for
dissemination of information– Facilitates the discovery of potential collaborations– An integrated portal for diverse content and applications

DCO Extension for Data Types
15
A Few Boundary Activities
• Given a DOI pull publication information from CrossRef
and/or Web of Science
• DCO IGSN Allocation Agent to work with the IGSN
Registry
• Integration with existing data portals and repositories
• Data Rescue activities

Modern informatics enables a new scale-free framework approach
• Use cases• Stakeholders• Modeling• Ontologies• Evaluation

RDA DTR and PIT adoption
The DTR primitives are comparable to a list of BASIC DATA TYPE CLASSES in the DCO ontology, e.g. Dataset, Image, Video, Audio, etc.
A registered DCO dataset is asserted as an instance of one of those basic data type classes.
It is possible to further annotate the dataset with the SPECIFIC DATA TYPES defined within a DTR, and each data type has a unique PID.
A Few Boundary Activities
Results of data type specification
• Updates to the DCO Ontology:– A new class dco:DataType. Each specific data type is an instance of it– An object property dco:hasDataType linking a dataset and a data type– A collection of other classes and properties associated with dco:DataType
