Export Descriptive Metadata From Dataset

[posixeleni]

Need to design an export metadata tool for datasets in Dataverse 4.0 which will allow an end-user the option to export the descriptive metadata of a Dataset into the following formats:

1. Native JSON Metadata
2. DDI 2.5 XML (not the full just the "study" metadata? For tabular metadata we may want to export this into a different file especially if dealing with files that are very large see Export File's Variable Metadata From Datasets With Tabular Data #908 )
3. Data Cite 3.0 XML
4. Dublin Core XML
   • Simple
   • DC-Terms
5. VO Metadata XML
6. ISA-Tab

Here's an example of a data repository offering multiple metadata export options from Data Univ of East London http://data.uel.ac.uk/3/:

I just wanted to remind everyone that a key function of the export is not only to share metadata but to store it in the file system in a preservation format.

Currently the version 4.2.1 we are testing only stores metadata in the database. For archives to use the Dataverse the metadata needs to be stored on disk as a preservable format like JSON or XML. That will allow it to be preserved with the digital objects in a preservation system.

I think I overlooked @posixeleni's spreadsheet in my issue #2357. However, it is still relevant in light of @jonc1438's comment.

@sekmiller - is this part of the export work? It's marked as part of 4.5 but I'm unclear on the status. Thanks!

[sekmiller]

Yes, This is part of the export work. As it stands now, all supported export formats (DDI, Dublin Core and json) will be saved to the file system at dataset publication time. We might need to run a script to catch everything that hasn't been exported to the file system at the time we deploy 4.5. I think Leonid was adding a timer job for this. (I know he added "lastExportTime" as a field for datasets.) I will check with him.

Thanks @sekmiller !
