Virtual organizations of researchers need effective tools to work collaboratively with huge sets of heterogeneous data distributed over HealthGrid. This paper describes a mechanism of supporting Digital Libraries in High-Performance Computing environment based on Grid technology. The proposed approach provides abilities to assemble heterogeneous data from distributed sources into integrated virtual collections by using OGSA-DAI. The core of the conception is a Repository of Meta-Descriptions that are sets of metadata which define personal and collaborative virtual collections on base of virtualized information resources. The Repository is kept in a native XML-database Sedna and is maintained by Grid Data Services.
研究人员的虚拟组织需要有效的工具来与分布在HealthGrid上的大量异构数据进行协作。本文描述了一种基于网格技术在高性能计算环境中支持数字图书馆的机制。所提出的方法通过使用OGSA-DAI提供了将来自分布式源的异构数据组装成集成虚拟馆藏的能力。该概念的核心是元描述存储库，元描述是基于虚拟化信息资源定义个人和协作虚拟馆藏的元数据集。该存储库保存在原生XML数据库Sedna中，并由网格数据服务进行维护。
