The Infrared Science Archive (IRSA) at the Infrared Processing and Analysis Center (IPAC) is charged with archiving data from NASA's infrared astronomy projects. Since 1997, IRSA has provided support to the massive datasets generated by the 2MASS project. Services have been developed to perform rapid querying of massive datasets, online real time access to a TB-size images database, and cross-correlations between massive datasets. IRSA is building on this work to develop a cross-archive access toolkit that will meet the needs of a National Virtual Observatory. In this paper we describe one aspect of this: OASIS, the On-line Archive Science Information Services astronomical archive integration Java client toolkit, which provides advanced visualization capabilities and distributed data access.
