摘要: Service-Oriented Architecture (SOA) and Web Services (WS) offer advanced flexibility interoperability capabilities. However they imply significant performance overheads that need to be carefully considered. Supply Chain Management (SCM) Traceability systems are an interesting domain for the use of WS technologies usually deemed too complex unnecessary in practical applications, especially regarding security. This paper presents externalized security architecture uses eXtensible Access Control Markup Language (XACML) authorization standard enforce visibility restrictions on trace-ability data a supply chain where multiple companies collaborate; assessed by comparing ‘raw’ implementations — Lists, Tokens, RDF Assertions with their XACML-equivalents.
