5. Deep Carbon Virtual Observatory 5 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 shared Data intensive – volume, complexity, mode, scale, heterogeneity, … in an OPEN WORLD 5

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 (Fox et al., 2014) 6

29. 29 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

30. 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 30
