2. Rolling Deck to Repository (R2R)
Overview
Mission:
Stewardship of environmental sensor data routinely acquired by U.S. academic research vessels
Services:
Publish master cruise catalog
Document, preserve, disseminate original field datasets
Assess quality of selected data types
Create post-field data products
Support at-sea event logging
Support:
NSF , ONR, NOAA, SOI, UNOLS

3. Cruise Catalog
Inventory of 6,500+ expeditions on U.S. research vessels, mainly since 2000
Enables linking of cruise-related data and documents at 16+ partner repositories

4. Motivation Old way: Data from U.S. cruises have historically been
stovepiped by program/discipline.
New way: Linking data across repositories drives the 3 “R” ’s
  Reproducibility (what journals want)
  Reuse (what funders want)
  Recognition (what scientists want)

Motivation
In an ideal world:

Paper

6. Solution R2R’s two-track implementation:
Publish entire Cruise Catalog as a Linked Data graph where each Cruise is a RDF Resource.
Publish a DOI for every Cruise where each Cruise has a DataCite XML Record.
In both cases, a Cruise is a Resource of Type=Event,
with links to Related Resources.

7. Identifiers For class/type vocabularies, R2R reuses terms from the
NERC Vocabulary Server:
L06 Platform Types
L05 Instrument Types
L22 Instrument Make/Models
C77 Shipboard Activity Types
P02 Data Types
P06 Unit Types
L05: SeaDataNet device categories (e.g. current meters)

8. Identifiers For instances, R2R links to registries:

Identifiers
For instances, R2R links to registries:
R2R - Cruise eg. we are the authority for US academic fleet
ICES - Platform (NVS:C17)
GRID - Organization
ORCID - Person
IGSN - Sample
DOI - Dataset, Document, Article
OFR - Funder
RE3 - Repository
SeaVoX - Waterbody (NVS:C19)
SDN - Port (NVS:C38)
OFR: Open Funder Registry (from CrossRef, IDs for grant giving organizations)

9. Partnerships
R2R has “reciprocal linking” arrangements with other repositories eg.
Biological and Chemical Oceanography Data Management Office (BCO-DMO)
CLIVAR and Carbon Hydrographic Data Office (CCHDO)
Interdisciplinary Earth Data Alliance (IEDA)
Index to Marine and Lacustrine Geological Samples (IMLGS)
Incorporated Research Institutions for Seismology (IRIS/OBSIP)
Shipboard Automated Meteorological and Oceanographic System (SAMOS)
System for Earth Sample Registration (SESAR)

10. Challenges Work in progress:
Community has not reached consensus on all Identifier types eg. Instruments, Projects, Organizations.
Significant backfill mapping required.
Identifier systems are not perfect, eg. a person can have more than one ORCID.
