Mapping ISO dates to GeoDCAT-AP

[uvoges]

There are three dates from the ISO metadata (metadata related to the data/Ressouce) that are mapped to DCAT-AP when present, the creation date, the publication date and the date of the last modification. I guess the corresponding XPath in ISO19115/19139 is: gmd:identificationInfo/(srv:SV_ServiceIdentification|gmd:MD_DataIdentification)/gmd:citation/gmd:CI_Citation/gmd:date.
The dates are mapped according to their CI_DateTypeCode. Different codeListValues are mapped to different elements in DCAT-AP.
Example: DCAT-AP: dct:issued - This is the Date of publication

 <dct:issued rdf:datatype="http://www.w3.org/2001/XMLSchema#date">2010-10-05</dct:issued>	

mapping from ISO19115-Xpath:

/MD_Metadata/identificationInfo/MD_DataIdentification/citation/CI_Citation/date/CI_Date/date/gco:Date[/MD_Metadata/identificationInfo/MD_DataIdentification/citation/CI_Citation/date/CI_Date/dateType/CI_DateTypeCode==‘publication‘]

The list below shows the different mappings to DCAT-AP:

codelListValue	DCAT-AP
creation	dct:created
publication	dct:issued
revision	dct:modified

@uvoges What you describe is also described in B.6.11 Temporal reference and metadata date –*Additional extent information for the dataset (vertical and temporal) and *Metadata date stamp and handled here in the XSLT.

What is your suggestion here?
