---------------------------------------
Summary: NetCDF to ISO 19115:2014 mapping
Key: SIS-361
URL: https://issues.apache.org/jira/browse/SIS-361
Project: Spatial Information Systems
Issue Type: Task
Components: Storage
Affects Versions: 0.7, 0.6, 0.5
Reporter: Martin Desruisseaux
The {{org.org.apache.sis.storage.netcdf.AttributeNames}} class defines a
mapping from NetCDF attributes to ISO 19115:2003 metadata. This mapping is
defined by the following file:
*
https://github.com/Unidata/threddsIso/blob/master/src/main/resources/xsl/nciso/UnidataDD2MI.xsl
However as of June 2017, this file seems to have been defined for a mapping to
the 2003 version of ISO 19115. A mapping to the ISO 19115 revision published in
2014 could make some difference. This task enumerate some possible changes.
Ideally, those changes should be submitted to the UCAR community. Whether
Apache SIS should apply them on its own or not is an open question.
h2. ACDD {{history}} attribute
The NetCDF {{history}} attribute is documented as "Provides an audit trail for
modifications to the original data". It is currently indirectly mapped to data
quality information, which is defined in ISO 19115 as "overall assessment of
quality of a resource(s)":
{noformat}
Metadata.dataQualityInfo.lineage.statement = $history
Metadata.dataQualityInfo.scope.level = dataset
{noformat}
Since ISO 19115:2014, we could use the following instead. Documentation said
"Information about the provenance, sources and/or the production processes
applied to the resource", which seems more appropriate:
{noformat}
Metadata.resourceLineage.statement = $history
{noformat}
