> 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}
