MoonDB’s Goals

• advance preservation, access and utility of lunar sample data• help investigators ‘rescue’ (restore) and share

unpublished data

• compile data from the literature into a PetDB-type synthesis

• provide a platform for future data to be made openly accessible, while being seamlessly integrated with the historical data and equivalent data for terrestrial samples.

LPSC 2015 Workshop: Restoration and Synthesis of Planetary Geochemical Data 4

MoonDB’s Deliverables

• Development of MoonDB

• compile lunar sample data from the literature into an online searchable synthesis database

• Rescue of Lunar Sample Data at Risk

• rescue unpublished legacy data and metadata that are in danger of being lost to complement the published datasets

Two Steps to Make Data Useful

7

1. Restore the data

2. Synthesize the data

LPSC 2015 Workshop: Restoration and Synthesis of Planetary Geochemical Data

Restoration of “Data at Risk”

• "Data at Risk” are scientific data that are • not in formats that permit full electronic access to the information they

contain.

• Data at Risk may be • non-digital (e.g., handwritten or photographic),

• on near-obsolete digital media (such as floppy disks),

• or insufficiently described (lacking metadata).

• Some born-digital data are considered "at risk" if they cannot be ingested into managed databases because they lack adequate formatting or metadata.

Definition from the ICSU CODATA Data at Risk Task Group (DARTG)

LPSC 2015 Workshop: Restoration and Synthesis of Planetary Geochemical Data 8

Data Rescue Initiatives

• ‘Data at Risk’ Task Group @ CODATA• Phase I: Build inventory of data that are at risk

• Phase II: Design missions to rescue that information

• ‘Heritage Data’ Interest Group @ Research Data Alliance

• International Data Rescue Award in the Geosciences• Joint initiative of IEDA (Integrated Earth Data Applications) and Elsevier

• First award in 2013

• 2015 award to be announced at EGU 2015

• IEDA Data Rescue Mini-Awards

Lessons Learned

• Investigators Lessons• Take ownership of your own legacy

• Data curation by others may not be complete or correct

• Data rescue of an entire career does not need to be overwhelming • Start with small steps• Disciplinary repositories will help and guide you to what is needed

• Despite the time investment, data rescue is worth it• Others will now be able to re-use the data• Notes taken years ago actually explain anomalies

• Repository Lessons• For Long Tail Data, every project is different • A small incentive will motivate investigators• Data Rescue missions help the repository determine next steps for

development of tools and services

Getting the data for the synthesis

• Many challenges• Data are dispersed throughout the literature.

• Many data were never published.

• Data are not sufficiently documented (inconsistent or missing metadata).

• Solutions• Data rescue

• Data managers

• Students/interns

LPSC 2015 Workshop: Restoration and Synthesis of Planetary Geochemical Data 30

Data Restoration Needs

• Digitization – transcribe from analog media into spreadsheets; help from students?

• Documentation – samples, provenance (lab, instrument, etc.), data quality; EarthChem data templates

• Standardization – MoonDB vocabularies & data templates

• Accessibility – data publication (ECL), links between systems

• Citability – DOIs, example citations

• Guidance/Training – calls and emails with disciplinary repository staff, regular communication (meetings, webinars)
