The goal of the Tsimmis Project is to develop tools that facilitate the rapid integration of heterogeneous information sources that may include both structured and unstructured data. This paper gives an overview of the project, describing components that extract properties from unstructured objects, that translate information into a common object model,(More)
The TSIMMIS project [I] provides an architecture and tools for accessing multiple heterogeneous information sources by translating source information into a common self-describing object model, called the Object Exchange Model (OEM) [2]. TSIMMIS provides integrated access to heterogeneous sources through a layer of source specific translators as well as "(More)

1 TSIMMIS and its Components A common problem facing many organizations today is that of multiple, disparate information sources and repositories, including databases, object stores, knowledge bases, le systems, digital libraries, information retrieval systems, and electronic mail systems. Decision makers often need information from multiple sources, but(More)

(sampled twice a day) of sea level pressure data (single precision oating point) generated by UCLA AGCM model with a 4 Latitude by 5 Longitude grid cell resolution is 9250560 bytes (730x44x72x4). Each grid \slice" is therefore 12672 bytes. In this example, the dataset was stored in a HDF le located on the same machine as the MD-CellularGridCoverage object,(More)
