The level of integration varies depending on the capability of the individual data provider. Some sources are simply viewed as file systems from which the VITMO selects data. Others provide a wealth of individual services that must be selectively integrated. The highest level of integration occurs with peer systems that support ontologies or other knowledge-based representations of data resources. These systems allow VITMO to move the search from a low-level one where VITMO must maintain knowledge about all of the products, to a high level one where VITMO makes high-level requests of the other system and receives the desired responses without knowledge of low-level details. This latter approach is the one that VITMO is using in its integration with the Virtual Solar-Terrestrial Observatory (VSTO), an ontology based system. In this talk we will compare and contrast the experiences of integrating with a system providing a large variety of individual services and one that provides a seamless system-level mapping using ontologies. inproceedings American Geophysical Union, Fall Meeting (AGU2007) morrison2007leveraging Leveraging Someone Else's Knowledge Based System 2007 Year Title Natural science Tag Eos Trans.
