Hi there,
As we implement a DWCA generator I've stumbled on a number of minor bits in reference to http://tools.gbif.org/dwca-validator/. I understand how to get around these things, but resolving them might lower the barrier to entry for others.
When I validate a DWCA
1) then I see a link 'Dublin Core' (http://code.google.com/p/darwincore/source/browse/trunk/dwca-reader/src/test...) that link is broken
2) and I have no metadata file then the instructions under Metadata as to what to do to resolve the problem (i.e. do next) are essentially unusable for the non-technically oriented
3) and I read this: "All null values are empty strings." in green and I get this immediately after "Error scanning records: java.lang.NullPointerException" then I am confused I would be less confused with a literal example of the issue
4) and I have an id column in [0], and that id column is mapped to nothing then I see under Darwin Core Occurrence 'Core Record ID mapped to nothing' and I think 'OK' then at the bottom of that list I see 'Unknown term http://purl.org/dc/terms/identifier mapped to column 0' and I am confused as to this (auto-mapping?) that has a namespace (http://purl.org/dc/terms/), and a term (identifier), both of which I have not referenced and I don't know what todo
Cheers, Matt
