[−][src]Crate rdftk_io

Traits for reading/writing Statements and Graphs as well as implementations for common file formats.

The following are some well-known formats (see Wikipedia for a description of different serializations), support is indicated in the final column with an R for read support and W for write support. One additional module, dot allows for the creation of GraphViz dot files for a visualization of a graph's structure.

Module	Name	MIME Type	Specification	R/W
`nt`		`application/n-triples`	W3C	W
`nq`		`application/n-quads`	W3C	W
`n3`		`text/rdf+n3`	W3C Submission
`turtle`		`text/turtle`	W3C	W
`xml`	RDF/XML	`application/rdf+xml`	W3C
`json`	JSON-LD	`application/ld+json`	W3C
TBD		`text/html`	W3C
TBD	RDF/JSON	`application/rdf+json`	W3C
TBD	TriG	`application/trig`	W3C
TBD	HDT	?	W3C Submission
TBD	BinaryRDF	`application/x-binary-rdf`	Community

Each module will also provide public constants NAME, FILE_EXTENSION, and MIME_TYPE.

Example

TBD

Modules

dot	Provides for writing a `Graph` instance in the GraphViz dot file format.
nq	Provides for writing a `NamedGraph` instance in the RDF 1.1 N-Quads, a line-based syntax for RDF datasets, format.
nt	Provides for writing a `Graph` instance in the RDF 1.1 N-Triples, a line-based syntax for an RDF graph format.

Traits

GraphReader	Read an entire `Graph` from the provided implementation of `Read`.
GraphWriter	Write all `Statement`s in the `Graph` using the provided implementation of `Write`.
NamedGraphWriter	Write all `Statement`s in the `NamedGraph` using the provided implementation of `Write`.

Functions

write_graph_to_string	A convenience function that will return a String containing the output of the `GraphWriter` for the given `Graph` instance.
write_named_graph_to_string	A convenience function that will return a String containing the output of the `NamedGraphWriter` for the given `NamedGraph` instance.
