Problems solved by technology

RDF itself is an XML document, which conforms to the XML grammar structure, so although it can be parsed by a general-purpose XML parser, there is no class library for parsing and generating complex RDF format files for direct calling

Embodiment Construction

[0032] The present invention provides a method for parsing an RDF format file and a method for generating an RDF format file, wherein the parsing method for an RDF format file comprises the following steps:

[0033] 1) Initialize the StreamReader class to bring in the RDF file path, convert the RDF file into a Stream stream file, and then initialize the XmlDocument class object, and convert the file stream into the corresponding XmlDocument class through the object's Load method;

[0034]2) Call the DocumentElement method inside the XmlDocument class to convert the XmlDocument class into the corresponding XmlElement document class, and obtain N Node node blocks of the document through the internal attribute value ChildNodes. The node object represents a single node in the XmlElement document tree. For example: P 1 ,P 2 ,P 3 ......P n ;

[0035] 3) Obtain the name of the corresponding node through the attribute of LocalName in the split Node node block, and then obtain the ...

Abstract

The invention relates to an RDF format file analysis method and an RDF format file generation method. The analysis method comprises the following steps: initializing a StreamReader class to bring in an RDF file path, converting an RDF file into a Stream stream file, initializing an XmlDocument class object, and converting a file stream into a corresponding XmlDocument class; the XmlDocument classis converted into a corresponding XmlElement document class, N Node node blocks of the document are obtained, and a node object represents an independent node in an XmlElement document tree; and obtaining names of corresponding nodes from the obtained N Node node blocks through attributes of the point LocalName, obtaining an attribute set of the nodes, completing analysis of the RDF, and generating a corresponding RDF analysis class. The method has the advantage that software using metadata can be manufactured more easily and quickly.

Description

technical field [0001] The invention belongs to the field of data management, and relates to a file parsing method and a generating method, in particular to an RDF file parsing method and a generating method. Background technique [0002] RDF is the resource description framework, which is the abbreviation of Resource Description Framework. It is usually used to express metadata about Web resources. An RDF file contains multiple resource descriptions, and a resource description is composed of multiple statements. A statement is A triplet consisting of resource, attribute type, and attribute value represents an attribute of the resource. With RDF, any resource can be described using its own vocabulary. [0003] RDF is used when information needs to be processed by applications rather than just displayed for human viewing. RDF provides a general framework for expressing this information and enabling it to be exchanged between applications without loss of semantics. Since it...
