| 摘 要： | UDDI要求实体在发布时必须被分配一key作为其唯一性标识。UDDIV2的key由UDDI节点生成,key的可读性差且不可移植。UDDIV3的uddiKey方案规定key必须采用URI格式,并通过引入key分区概念使发布者为新实体分配key成为可能。通过研究uddiKey的格式及两种分配方式,探讨了解决老版本key问题的办法,提出了单注册中心和多注册中心环境下的uddiKey分配策略,其核心内容是确保key的唯一性,特别是在多注册中心环境下,需要一根注册中心负责key空间的分配。

| Abstract: | UDDI requires that an entity should be assigned a key as its identifier for uniqueness when published. UDDI V2 keys are generated by UDDI nodes,so they lack readability and are non-portable.UDDI V3 uddiKey scheme prescribes that the form of keys must be URI,and the introduction of the conception of key partition make it possible for a new entity to be assigned a key by a pulisher.By studying uddiKey formats and its two assignment means,the solution to the old-version key issues was discussed and the key assignment policies in a single-registry and a multi-registry environment were suggested,the core of which is the guarantee of key uniqueness,especially in a multi-registry environment,a root registry is needed to take responsibility for key space assignment. |
