Discussion
4/13/2015 SPM1.36
Samples are the source of observational data and measurements across disciplines.
Samples provide irreplaceable evidence of long-term historical trends.
Samples serve as standards or references.
Samples record unique events in history and/or unique opportunities to collect specimens (e.g. moon rocks).

Samples are often expensive to collect (drilling, remote locations).
Many samples are unique and irreplaceable. Re-analysis augments utility of existing data.

• “Poor and uneven access and management of sample collections”
• “Incomplete sample tracking and linking of samples to analyses in the literature and databases”
• “Poor discoverability of existing samples”

• Lack of resources: space, staff, tools• Lack of policies• Lack of leading practices & standards
connect the physical samples with the digital data create “virtual representations” of samples online
(digitization of existing collections)
ensure unique identification of samples so they can be properly cited and located
network catalogs and registries to allow discovery of samples across distributed systems
develop & implement best practices for consistent and comprehensive documentation of samples
preserve & curate the physical objects sustain storage facilities to curate actual physical objects;
use IT to facilitate digital collection management.

Find the sample and contact its owner
Find all publications that mention a specific sample
Find all data for that sample in easily usable, electronic format
Find other samples with similar properties geospatial
temporal
compositional

Online sample catalogs can dramatically improve discovery and access of collections for broad audiences.
Software tools can support and streamline collection management.
Interoperability provides unprecedented capabilities to Link data, samples, and publications
Link all data acquired on a single sample & subsamples
Integrate sample-based data with other data types

“The key measurement was the one backarc basalt called "PPTUW”...Subsequent efforts to confirm the observation ran into problems. The apparently-same sample was variously called PPTU, PPTUW/5, PPTUW-1, and TVZ19 in four other papers. None of those papers gave its latitude and longitude…!”(J. Gill and E. Todd, personal communication 2013, related to IEDA data rescue effort)

Accounts that registered
Metadata standards for samples: how generic, how specific?
At what granularity should samples be cited? (Credit to the original collector)
Can the IGSNs of an article be integrated into DOI metadata (related identifier) so they become searchable? Should samples be 'cited' in a distinct list?
What protocols can be used to make IGSNs in articles interactive? Can DOIs be used to resolve IGSNs?
How can we reach authors and editors to encourage use of IGSNs?
