changed waf xml not updating during ckan harvest

[fostermh]

re-harvesting of WAF metadata does not update a dataset even though it has been changed on the waf. Perhaps an issue with how waf_modified_date is populated?

this Line 752 in the spatial harvester base checkes metadata_date of old and new harvested metadatra when doing an update. metadata_date is populated from "metadata-date" in spatial model harvester Line 713.

Currently metadata-date is populated by the following xpaths:

"mdb:dateInfo/cit:CI_Date[cit:dateType/cit:CI_DateTypeCode/@codeListValue='creation']/cit:date/gco:Date/text()",
"mdb:dateInfo/cit:CI_Date[cit:dateType/cit:CI_DateTypeCode/text()='creation']/cit:date/gco:Date/text()",
"mdb:dateInfo/cit:CI_Date[cit:dateType/cit:CI_DateTypeCode/@codeListValue='creation']/cit:date/gco:DateTime/text()",
"mdb:dateInfo/cit:CI_Date[cit:dateType/cit:CI_DateTypeCode/text()='creation']/cit:date/gco:DateTime/text()",

This does not take into account publication or revision dates. It probably should.

The current setup of the harvester requires a change to the dates in the metadata before a record will be updated. This is likely good metadata practice but may not be convenient for some workflows. More discussion needed.

update the metadata-entry-form now updates the lastUpdated data every time the form is saved so this is no longer an issue with metadata generated from the form. Correct metadata would be to update this date when changing the xml anyway so I think this is the appropriate workflow.
