Registries and Clearinghouse
- Use of
clearinghouse for AIP-3 metadata record experiments
- Practice for
depositing / registering vocabularies / ontologies
Lieberman, Nadine Alameh, Steve Browdy, Joan Maso, Stefan Falke
needed between GEO ontology task and AIP-3 semantics group, but the GEO
task is going very slowly.
- Steve - presentations only change
- Steve - lots of
functional testing involved of all three clearinghouses, using the
Eliot Christian Z39.50 tool. USGS clearinghouse did much better. Not
clear why that work went into Yang's group.
clearinghouse requirements document - registries, clearinghouses,
- Connection to AIP-3:
- Can GEOSS Common
Record (GCR) metadata be harvested?
- Can the clearinghouse be
queried for GCR mapped from other harvested metadata?
- Addition of Data Quality Status -
- Joan -
connected to GEO "Label" expression of data quality for GEOSS use.
- tend to have the problem of needing "quality of metadata" measures,
or meta-metadata, which is not yet well standardized
- Stefan -
within air community, quality propagation and provenance is a concern.
QA4EO may be concerned with this, but focus and current activity seem to
be on cross-calibration, not propagation or documentation
- contextual metadata issue - who else has used data, what are its
limitations or intended use? Connection between quality and suitability.
Potential conflict with GEOSS goal of "unintended use".
- Josh -
in particular, data product may be correlated with / derived from
another product which someone else tests / corroborates with the first
product. Can we suggest test of these particular examples of
- Data quality flags from EPA --- need to see
whether those are general, and also useful. Tend to be for individual
values, such as "outside of calibration range"
- check with Doug Nebert / Phil Yang about clearinghouse support for
- Joan - review ISO Core values for completeness
- link to consolidated requirements
- Nadine - Check with George
on workshop outcomes - task coordination
- Stefan - more
generalized data quality flags
