摘要
网格中有关资源的信息是网格的元信息,有效地存储、管理这些元信息是网格首先要解决的问题。使用半结构化数据模型ORA-SS描述网格元信息可以表达资源信息间的多元关系,明确地区分资源的属性和资源之间关系的属性,克服LDAP只能表达简单的树形结构的缺点。提出了一种将ORA-SS模型应用到织女星网格元信息管理的方法,并给出了具体的设计和实现方案。
The information about grid resources is the meta-information of the grid. Effective storage and management of these metainformation is the primary problem of the grid. The semi-structured data model ORA-SS can express the multiple relationships between grid resources and clearly distinguish attributes of the resources and attributes of the relationship. The shortcomings of the LDAP that can only express a simple tree structure is overcome. An approach applying ORA-SS to VEGA grid meta-information management and the detailed design and implementation of the system are presented.
