Back to Preservation and Stewardship
Supporting the long-term preservation of Earth system science data and information is core of the Data Preservation and Stewardship Cluster. As such, a formalism is needed to codify the information. A future-looking approach is to leverage semantic web technologies to capture the knowledge representation and to enable flexible usage of this information.
We would like to start with practical use cases in preservation modeling, then work on a small and manageable model, and continually increment on a working design. Ideally, we should converge with support the information identified in the Provenance and Context Content Standard.
Some major steps planned:
1. Define what we would like from a "Preservation Ontology"
- Initially covered in the 2011-03-09 telecon.
2. Define practical Use Cases
3. Extract high-level requirements
4. Adopt/reuse existing provenance models
- A good starting point: OPMO: The Open Provenance Model OWL Ontology
5. Extend model with more focus on Earth science preservation
- Include provenance and context
6. Infuse model into data systems
- some aspects covered by ACCESS project(s)?
7. Updates and Refinements
Following the steps from the roadmap, the approach will also include the following:
- Follow closely the Provenance and Context Content Standard.
- e.g. processing history, data formats used, product development history, algorithms, ATBDs, product tools, QA, validation, software.
- On preservation, do we want to model with provenance and/or context?
- Mark P on provenance vs context:
- provenance is for reproducibility.
- context is for someone use the information for something else.
- Start with Open Provenance Model
- Explore if possible to map some of the preservation model information to ISO 19115 - Metadata for Geographic Data?
Here are some initial grouping place holders:
Capturing preservation information
- capturing data production provenance
- capture data product context
Using preservation information
- provenance for reproducibility
- context for reuse in other domains
