== Overview ==

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.

== Motivations ==
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 and their time-stamps are visible to a web browser or client. Crawlers are able to parse the file listings and date-time stamps 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.

== Proposal == 
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 can choose WAF harvest subtype.
