Exporting Records

To Do: Update with addtional formats in GeoData

GeoNetwork has three different export options to export metadata. They operate on the selected sets of metadata from the search results. As such they are accessible from the “actions on selection” menu as shown in the following example:

Export as a ZIP archive

Note:: This is not a zip file containing just the metadata record. The primary purpose of this option is exchanging records with another GeoNetwork system.

When a selected set of metadata records is exported as a ZIP archive, each metadata record is inserted in the ZIP archive as a directory containing the metadata, any data uploaded with the metadata record and the thumbnails. This type of ZIP archive is the MEF (Metadata Exchange Format) Version 2.0.

Export as a CSV file

When a selected set of metadata records is exported as a CSV/TXT file, the following process takes place for each metadata record:

  • a brief summary of some of the elements from each selected metadata record is generated

  • the metadata elements that are included are predefined within GeoData for each metadata standard. As a result different ISO versions may have different column names.

  • summary elements customizations can be developed, contact NAL-GeoData@ars.usda.gov for details

  • in the brief summary are extracted (They may differ according to the metadata schema, for example different ISO versions)

  • a title record with comma separated element names is created

  • the content of each element is laid out in comma separated form. Where there is more than one child element in the brief element (eg. for geoBox), the content from each child element is separated using ‘###’.

An example of an ISO metadata record in CSV format is shown as follows:

"schema","uuid","id","title","metadatacreationdate","geoBox"
