Utilities to connect Raphael and Donatello.

*no-defaults* clj/s

A flag to indicate that nil bases or namespaces should result in no base or namespace to be written. The default is to maintain the existing base and namespace if none are specified.

add-all clj/s

(add-all idx st)

Inserts all triples in a sequence into a nested map

index-add clj/s

(index-add idx [a b c])

Merges a single triple into a nested map

parse clj/s

(parse s)

Parses input and creates a graph

parsed-graph clj/s

(parsed-graph {:keys [base namespaces triples] :as parsed})

Converts a graph parsed by Raphel into a nested map, with metadata for the prefixes and base.

round-trip-generator clj/s

(round-trip-generator)

Creates a new RoundTripGenerator

simple-graph clj/s

(simple-graph triples)

Creates a nested-map version of a graph from a sequence of triples

transform-file clj

(transform-file infile tx-fn outfile)

Transforms a TTL file. Accepts an input filename, a transforming function, and an output filename. The transforming function receives:

• graph: the graph to transform.
• namespaces: The prefix namespaces of of the graph.
• base: The base of the graph. The result may be one of:
• a vector of: [new-graph namespaces base]
• a graph with a meta map of :namespaces and :base Both the base and namespaces are optional to return. If they are not returned, then the previous base and namespaces will be used, unless no-default has been set.

transform-string clj/s

(transform-string in tx-fn)

Transforms a string containing TTL. Accepts an input string, and a transforming function. Returns a string containing the transformed TTL. The transforming function receives:

• graph: the graph to transform.
• namespaces: The prefix namespaces of of the graph.
• base: The base of the graph. The result may be one of:
• a vector of: [new-graph namespaces base]
• a graph with a meta map of :namespaces and :base Both the base and namespaces are optional to return. If they are not returned, then the previous base and namespaces will be used, unless no-default has been set.

uri clj/s≠

clj

(uri s)

cljs

write-graph clj/s

(write-graph out g)

(write-graph out g {:keys [namespaces base]})

(write-graph out g namespaces base)

Writes a parsed graph to a stream as Turtle. out - An OutputStream to write to. g - The graph to write. Tha base and namespace prefixes for the graph may included as:

• metadata (as a map with keys of :namespaces and :base).
• a map (as per the metadata map).
• as individual arguments.
