Variables

var ErrInvalidRDFFound = errors.New("invalid JSON-LD context")

ErrInvalidRDFFound is returned when normalized view contains invalid RDF.

Functions

func AppendExternalContexts

func AppendExternalContexts(context interface{}, extraContexts ...string) []interface{}

AppendExternalContexts appends external context(s) to the JSON-LD context which can have one or several contexts already.

func TransformBlankNode

func TransformBlankNode(row string) string

TransformBlankNode replaces blank node identifiers in the RDF statements. For example, transform from "_:c14n0" to "urn:bnid:_:c14n0".

Types

type Opts

type Opts func(opts *processorOpts)

Opts are the options for JSON LD operations on docs (like canonicalization or compacting).

func WithDocumentLoader

func WithDocumentLoader(loader ld.DocumentLoader) Opts

WithDocumentLoader option is for passing custom JSON-LD document loader.

func WithExternalContext

func WithExternalContext(context ...string) Opts

WithExternalContext option is for definition of external context when doing JSON-LD operations.

func WithFrameBlankNodes

func WithFrameBlankNodes() Opts

WithFrameBlankNodes option for transforming blank node identifiers into nodes. For example, _:c14n0 is transformed into <urn:bnid:_:c14n0>.

func WithRemoveAllInvalidRDF

func WithRemoveAllInvalidRDF() Opts

WithRemoveAllInvalidRDF option for removing all invalid RDF dataset from normalize document.

func WithValidateRDF

func WithValidateRDF() Opts

WithValidateRDF option validates result view and fails if any invalid RDF dataset found. This option will take precedence when used in conjunction with 'WithRemoveAllInvalidRDF' option.

type Processor

type Processor struct {
	// contains filtered or unexported fields
}

Processor is JSON-LD processor for aries. processing mode JSON-LD 1.0 {RFC: https://www.w3.org/TR/2014/REC-json-ld-20140116}

func Default

func Default() *Processor

Default returns new JSON-LD processor with default RDF dataset algorithm.

func NewProcessor

func NewProcessor(algorithm string) *Processor

NewProcessor returns new JSON-LD processor for aries.

func (*Processor) Compact

func (p *Processor) Compact(input, context map[string]interface{},
	opts ...Opts) (map[string]interface{}, error)

Compact compacts given json ld object.

func (*Processor) Frame

func (p *Processor) Frame(inputDoc map[string]interface{}, frameDoc map[string]interface{},
	opts ...Opts) (map[string]interface{}, error)

Frame makes a frame from the inputDoc using frameDoc.

func (*Processor) GetCanonicalDocument

func (p *Processor) GetCanonicalDocument(doc map[string]interface{}, opts ...Opts) ([]byte, error)

GetCanonicalDocument returns canonized document of given json ld.
