ask-queryclj
(ask-query conn query-string)Returns true/false for query-string posed to conn
Returns true/false for `query-string` posed to `conn`
collect-kwis-and-literalsclj
(collect-kwis-and-literals macc k v)Returns macc' substituing v -> <v'>
Where
<macc> := {<k> <v'>, ...}, translated from a binding map from a query
<k> is a var in a query, :~ ':?.'
<v> is the raw value bound to <k> by the query response
<v'> is the translation of <v> into idiomatic igraph datatypes:
URIs -> KWIs
<data-time string> -> #inst ....
{:lang ... :string ...} #lstr <string>@<lang>
.^^transit:json -> decoded transit
Otherwise, just <v>
Returns `macc`' substituing `v` -> <v'>
Where
<macc> := {<k> <v'>, ...}, translated from a binding map from a query
<k> is a var in a query, :~ ':?.*'
<v> is the raw value bound to <k> by the query response
<v'> is the translation of <v> into idiomatic igraph datatypes:
URIs -> KWIs
<data-time string> -> #inst ....
{:lang ... :string ...} #lstr <string>@<lang>
.*^^transit:json -> decoded transit
Otherwise, just <v>collect-p-oclj
(collect-p-o graph-uri s acc p-o)Returns [<quad>, ...] with a quad added for s, p-o, graph-uri
Where
<quad> is a Grafter Quad
<s> is a URI for a subject
<p-o> := [<p-kwi>, <o-elt>]
<p-kwi> is the kwi for a predicate
<o-elt> is a kwi or literal object
<graph-uri> is a URI for some graph, or nil
NOTE: typically called to compose material to add to a graph.
Returns [<quad>, ...] with a quad added for `s`, `p-o`, `graph-uri` Where <quad> is a Grafter Quad <s> is a URI for a subject <p-o> := [<p-kwi>, <o-elt>] <p-kwi> is the kwi for a predicate <o-elt> is a kwi or literal object <graph-uri> is a URI for some graph, or nil NOTE: typically called to compose material to add to a graph.
date-time-regexclj
Matches the date-time-str encoded for #inst's, e.g. '2000-01-01T00:00:00Z'
Matches the date-time-str encoded for #inst's, e.g. '2000-01-01T00:00:00Z'
interpret-queryclj
(interpret-query conn query-string)Returns (<bmap'>, ...) returned from query-string posed to conn
Where
<query-string> is a SPARQL query
<conn> is a grafter connection implementing the proper interfaces for a query
<bmap'> := <bmap>, with datatypes translated to idiomatic igraph clojure objects
as appropriate, per the collect-kwis-and-literals function.
<bmap> is a binding map returned by posing <query-string> to <conn>
Returns (<bmap'>, ...) returned from `query-string` posed to `conn` Where <query-string> is a SPARQL query <conn> is a grafter connection implementing the proper interfaces for a query <bmap'> := <bmap>, with datatypes translated to idiomatic igraph clojure objects as appropriate, per the `collect-kwis-and-literals` function. <bmap> is a binding map returned by posing <query-string> to <conn>
make-graphclj
(make-graph conn graph-kwi)Returns an instance of GrafterGraph for conn and graph-kwi
Where
<conn> is a SailRepositoryconnection
<graph-kwi> is a keyword mapped to a URI by voc namespace metadata, or nil
to specify the DEFAULT graph.
See also the documentation for ont-app.vocabulary.core for discussion of
KWIs.
Returns an instance of `GrafterGraph` for `conn` and `graph-kwi` Where <conn> is a SailRepositoryconnection <graph-kwi> is a keyword mapped to a URI by voc namespace metadata, or nil to specify the DEFAULT graph. See also the documentation for ont-app.vocabulary.core for discussion of KWIs.
render-elementclj
(render-element elt)Returns either a URI or a literal to be added to a graph
Returns either a URI or a literal to be added to a graph
special-literal-dispatchclj
(special-literal-dispatch x)Returns :rdf-app/Instant, :rdf-app/DatatypeURI or nil for x.
Where
<x> is a literal value
:rdf-app/Instant triggers handling of an #inst
:rdf-app/DatatypeURI triggers handling as an xsd value or other ^^datatype.
nil signals handling with standard logic for literals per
rdf-app/render-literal-dispatch
Returns :rdf-app/Instant, :rdf-app/DatatypeURI or nil for `x`. Where <x> is a literal value `:rdf-app/Instant` triggers handling of an #inst `:rdf-app/DatatypeURI` triggers handling as an xsd value or other ^^datatype. `nil` signals handling with standard logic for literals per `rdf-app/render-literal-dispatch`
