This working group is concerned primarily with the scope, terminology, schema, and tools for defining physical sample identifiers and metadata, as well as addressing semantics for interoperability of data discovery, access & exchange. This work is interdependent with other working groups, especially WG2-Use Cases, and WG4-Workflow Applications. We need to be sure to coordinate with them.
We are emotionally invested in physical samples. People will want to use these standards/guidelines: collectors, researchers, and curators at, eg, universities, museums and agencies.
Assess and/or promote leading practices for relevant, commonly used, and/or emergent metadata and identifier guidelines for physical samples within Earth science communities, for interoperability that will result in improved discovery, access and understanding.
Key Questions (from Workshop 1 - 2015)
1. What is the scope of "physical samples" we will consider?
- Earth sciences, life sciences, space sciences
2. What are the minimum metadata fields required to facilitate functional & meaningful discovery of federated resources?
- Depends on use cases for field collection, curation, publishing, archive, search, and access for analysis of physical samples.
- Will differ by type of sample; need to develop multiple profiles
- Distinguish record content metadata and lifecycle/provenance metadata.
- Identify intersection & gaps across these standards and community conventions: ISO 19115, DataCite/DOI, IGSN, Darwin Core, Dublin Core
- Value-added metadata fields could help query filtering.
3. How will interoperability be facilitated and ensured?
- Using controlled vocabularies (CV's) - which are most widely used, or gaining traction?
- Using discovery & access brokering services for metadata crosswalks, format conversions, etc.
- Allowing the fewest options or exceptions in metadata guidelines; need to flexible but not at the expense of meaningful data exchange. Also have to recognize that we can't expect much uptake if we require "complete metadata".
- Using standard encodings, interfaces and protocols (OGC CSW, OAI PMH, etc.)
- Using unique, persistent sample identifiers & resolvers, building on community best practices (eg, IGSN, DOI and their possible convergence)
4. What are the leading practices we can learn from and share?
- Tools and practices for collecting & improving metadata throughout the physical sample lifecycle (eg, iPlant Collaborative, iDigBio; major collections curators; other EarthCube projects)
- Ensuring complete and accurate metadata from sample "handlers"
- Associating sampling protocols, documents, etc. to the sample record
Resources that would help
- Facilitated workshops to engage stakeholders
- Relationship with CODATA task force, IGSN, DataCite,
- EarthCube Office support for meetings and communications
