Electronic Records Data Transfer Protocol Based On OWL And Research Of Middle Ware Interface

Compared with the traditional paper record,the electronic record has many advantages:simple for storage;capacity is huge;convenient for find and modify;quick for transfer and exchange,which have greatly improved the efficiency of the life and work..Because of these advantages,more and more people use electronic records in our daily life. At the present stage to record-keeping system,mostly we use the traditional relational database,which makes inconvenient to find records between the various types of records.And,if we introduce OWL into the record storage system, this problem can be solved light.OWL has a very powerful vocabulary,and it increase a lot semantices based on description logic,which making use OWL to describe or to build motology is very convenient.OWL-based electronic records system is an electronic records preservation system which basis on the OWL,it can achieve the preservation of the records and support the search for related records. After build a trusted electronic records,we need to solve the problem that how exchange the data between the cilent side and server side,including records search,records storage,records update and records delete.We need to develop a data exchange protocol to make the records exchange and transfer more unified. Electronic records data transfer protocol is a bridge between client applications and server-side support system for data transmission and exchange, which provides the client can use the ways in which server-side data transmission and exchange, as well as the input parameters and output parameters of these methods need to meet the data format. This paper is mainly to study the theory and to develop a transfer protocol for OWL-based electronic records,and devise a model which can exchange large amounts of records data between client and server accordance with the protocol.The innovation and characteristice of this paper can be summarized as the following three points:First,after research for the requirement of the application system,we extend the SPARQL protocol,so that the new protocol can meet the needs of the data exchange.Second,using RDF specification to describe the records and the relationship between the records.RDF specification has their own vocabulary,and it can easily be used to describe resources and their relationships.Third,using SPARQL specification to describe the query condition.The SPAQRL specification is a W3C recommended specification. The query condition can be described to a consistent format by SPARQL,which has highly versatile.
