== Overview ==

We propose to add the ability to harvest from both
Z39.50 and WAF (web-accessible folders) and to modify/enhance the
harvest administrative interface.

 * '''App''': !GeoNetwork
 * '''Module''': Harvester

 * Vote proposed by A. Warnock on 2009-12-20.

----

== Motivations ==
GEOSS has a strong need to be able to harvest metadata from both Z39.50 sources and from simple web-accessible folders.  These
capabilities are not currently present in GeoNetwork but are straight-forward additions to the existing harvesting module.

== Proposal == 
We propose to add the ability to harvest from both
Z39.50 and WAF (web-accessible folders) and to modify/enhance the
harvest administrative interface.  WAF is quite simple - it's like
WebDAV only easier.  A simple wget-like function would suffice.

Experience in GEOSS indicates that not all desirable sources respond
correctly to blank queries, so we additionally propose that both Z39.50 and CSW ought
to include the capability to specify a query as part of the harvest
process.

=== Backwards Compatibility Issues ===
None forseen.

== Risks ==
None forseen.  Development will take place on a separate branch so that testing can take place before merging into the trunk.
