Attribute Convention for Data Discovery ISO Translation Notes
From Earth Science Information Partners (ESIP)
The translation between the Attribute Conventions for Data Discovery is subject to a number of assumptions or conventions described here.
People
The ACDD includes several types of people:
| ACDD Attributes | ISO Locations |
| creator_name, creator_email, creator_url, institution | citation/citedResponsibleParty role=originator |
| contributor_name, contributor_role | citation/citedResponsibleParty role=originator or author (may need adjustment) |
| publisher_name, publisher_email, publisher_url | citation/citedResponsibleParty role=publisher if in reference to traditional document publication MD_Distributor/distributorContact role=distributor if in reference to agent who is hosting the resource for access |
| project | Project keyword, aggregation information (initiative type = project) |
Keywords
The ACDD includes several attributes that make sense as keywords in ISO:
| ACDD Attributes | ISO Locations |
| keywords | theme keywords with thesaurus given by the keywords_vocabulary attribute |
| project | Project keyword with unknown thesaurus and aggregation information (initiative type = project) |
| publisher_name | Data Center keyword with unknown thesaurus |
| standard_names for parameters | theme keywords with thesaurus = standard_name_vocabulary |
Translation Revisions
Several changes were introduced into Version 2.0.2 of the stylesheet for transforming NcML to ISO in order to improve the rubric score for the resulting ISO metadata. The changes included:
- Including netcdf/@location in transform as distribution onlineResource
- Added tagname to writeResponsibleParty so that responsibleParties with
different UML roles could be supported (i.e. contact vs. distributor)
- Added urlName and urlDescription to writeResponsibleParty to add
content to the onlineResource
- Moved publisher from citation to distributor and included publisher_name as a dataCenter keyword.
- Added project as a keyword with type=project
- Added distributionInfo section to ISO if publisher or location exist.
