Harvest

• Web Service Methods
• Harvest()
• HarvestFrom(date)
• HarvestResource(VoResource)
• Harvest (OAI) HTTP Get.
• Harvest Web Services based on the MetaData
  Interface defined in the Grid Services group
  (other Resources) or these defined Interface
  methods for Registries.

Current Use Other

• Made all our Resources consistant ex ltResource
  xsitypeTabularSkyServicegt
• Changed to a XMLDB.
• Normally just Services with their endpoints are
  used.

XMLDB (eXist)

• Small Demo
• Seems to not be as good to use the xmlrpc with
  it, better to use REST style, or go through URL
  to cocoon.

Where we are heading

• Start populating the registry with real Data
  Center information.
• Sympathize with the audiences situation if
  appropriate
