Long Description

A basic parser and a set of simple utilities to parse N-Triples data.

N-Triples provides a simple format for representation of Semantic Web/W3C RDF semantic data. CL-NTRIPLES provides a simple and easy to use parser for Common Lisp applications.

6.1 Public Interface


6.1.1 Ordinary functions

Function: literal-string (triple)

Returns the literal-string value of the triple’s object.

Package

cl-ntriples.

Source

nt-parser.lisp.

Function: predicate? (triples predicate &key lang data-type)

Given the list of triples produced by PARSE-NT returns a list of triples with predicates matching the given one.

Package

cl-ntriples.

Source

nt-parser.lisp.


6.1.2 Generic functions

Generic Function: parse-nt (src)

Parses N-Triples from the given source. This method
accepts a file pathname, a stream, or a string.

Returns a list of triples consisting of three elements: subject, predicate, object. Subjects can be either an ‘uriref’ or a ‘nodeID’. Objects can be of three types: ‘uriref’, ‘nodeID’ or a ‘literal’. Depending on the type of the object it is encoded into a list.

Package

cl-ntriples.

Source

nt-parser.lisp.

Methods
Method: parse-nt ((src pathname))
Method: parse-nt ((src string))
Method: parse-nt ((src stream))

Function: parse-ntriple-triple (stream)

The triple consists of a: subject, predicate, object. All they are separated by whitespace. There is also a terminating full stop point in the end of a tripple.

Returns a list consisting of three elements corresponding to the tripple.

The syntax is:
triple ::= subject ws+ predicate ws+ object ws* ’.’ ws*
