How Metadata affects QC - Julie Bosch

MMI Project - Notes about conference from Aug 2005. OWL-based ontologies.

COTS/ONR Project - …

QARTOD 1 - Dec 2003. QA/QC flags to be defined. Test cases for flags. Pros and cons of existing standards.

QARTOD 2- Feb-Mar 2005. Discipline specific metadata: waves, in-situ currents, remote currents.

POST QARTOD 2 - How to fit QC data into FDGC format?

Salinity Workshop - Aug 2005. QC for real-time salinity measurements. Drafted metadata record example of salinity data attributes.

Waves - Nov 2005. Significant advancements on QC requirements and recommendations. Identify best practices for continuing discipline scientific approach.

Katrina Analogy - Damaged bridge = gaps in scientific community. Build gaps to create fluid workflow…

Why are ontologies important? - Luis Bermudez

Wikipedia definition of ontology. Wikipedia is not that reliable of a source, but it
good’s enough. Next is a longer more philosophical definition. Too long to repeat here.

Keywords from definition: Specific Purpose of Practical Difference

Example of Google Directory - Practical use of organization

Specification of conceptualizations. Ex. lake vs river. Each has properties: body of water… similarites identified.
Concepts are created and expressed as a class: Body of water, Lake, River
Classes are related.

Properties of class relations: isPartOf, isTransitive

Why use ontologies? Share common understandings, for software agents. Enable reuse of domainn knowledge. Make domain assumptions explicit.

Why part of QARTOD? - quality levels, flags, sensors, instrument methodology, calibration procedures, QC software, validation and verification methods, etc.
Can we map two different QC codesets?

Semantic issues - direct relations and inferred relations.

Use OWL format to build ontologies. Web Ontology Language. Based on RDF.. blah blah blah

How to convert to OWL? created tool called VOC2OWL. Java-based input form takes values and performs conversion. Other tools: Protege.

VINE - Vocabularly Integration Environment (oh, that’s what it stands for!). Mapping relations… this is sooooo MMI.
Notes about MMI Conference. Mapping results…

Best Practices Workshop on Salinity - Jim Boyd

- stick with small group - too many people causes confusion, requires “educating” across topical areas
- specifically defined outcome
- breakout rooms for each topical area
- reconvene in plenary to share
