WEBDAV Harvesting¶
This harvesting type uses the WebDAV (Distributed Authoring and Versioning) protocol or the WAF (web accessible folder) protocol to harvest metadata from a web server. It can be useful to users that want to publish their metadata through a web server that offers a DAV interface. The protocol permits retrieval of the contents of a web page (a list of files) along with the change date.
Adding a WebDAV harvester¶
Site - Options about the remote site.
Subtype - Select WebDAV or WAF according to the type of server being harvested.
Name - This is a short description of the remote site. It will be shown in the harvesting main page as the name for this instance of the WebDAV harvester.
URL - The remote URL from which metadata will be harvested. Each file found that ends with .xml is assumed to be a metadata record.
Icon - An icon to assign to harvested metadata. The icon will be used when showing search results.
Use account - Account credentials for basic HTTP authentication on the WebDAV/WAF server.
Options - Scheduling options.
Run at - The time when the harvester will run.
Will run again every - Choose an interval from the drop down list and then select the days for which this scheduling will take place.
One run only - Checking this box will cause the harvester to run only when manually started using the
Run
button on the Harvesting Management page.
Options - Specific harvesting options for this harvester.
Validate - If checked, the metadata will be validated after retrieval. If the validation does not pass, the metadata will be skipped.
Recurse - When the harvesting engine will find folders, it will recursively descend into them.
Privileges - Assign privileges to harvested metadata.
Groups - Groups can be selected from the scrolling list. When the
Add
button is pushed, a row of privileges will be created below the scrolling list for each group. Privileges can then be checked/unchecked for each group as required.Remove - To remove a row click on the
Remove
button on the right of the row.
Categories
Select one or more categories from the scrolling list. The harvested metadata will be assigned to the selected categories.
Notes¶
The same metadata could be harvested several times by different instances of the WebDAV harvester. This is not good practise because copies of the same metadata record will have a different UUID.
in order to be successfully harvested, metadata records retrieved from the remote site must match a metadata schema in the local GeoNetwork instance
