The purpose of this proposal is to allow users to harvest metadata from WAF catalog. In particular, the WAF contains XML files metadata or OGC Getcapabilities file.

Some catalogs are published by WAF protocal. A Web Accessible Folder (WAF) is an HTTP accessible directory of files, typically metadata files in XML format in which all files are visible to a web browser or client. Crawlers are able to parse the file listings and provide a search interface on these documents. In addition, some WAF contains OGC Service Getcapbilities file such as: http://mrdata.usgs.gov/wms.html, http://mrdata.usgs.gov/wfs.html
To allow users to get the metadata from the WAF catalogs, we added the WAF harvest to current GeoNetwork.
We extend the Web DAV server harvest to Web Access Folder/ Web DAV server harvest as below: To enable WAF harvest, a subtype list box is added to the Web Access Folder/ Web Dav server harvest management page. If the harvesting url is under WAF protocol, administrators may choose WAF harvest subtype. Some WAF url as below: http://capita.wustl.edu/DataspaceMetadata_ISO/ http://mrdata.usgs.gov/wms.html http://mrdata.usgs.gov/wfs.html
Backwards Compatibility Issues
New libraries added
jsoup.jar is used to parse the WAF page
