ask-jena-modelclj
(ask-jena-model g q)Returns true/false for ASK query q posed to Jena model g
Returns true/false for ASK query `q` posed to Jena model `g`
get-subjectsclj
(get-subjects jena-model)Returns a sequence of KWIs corresponding ot subjects in jena-model
Returns a sequence of KWIs corresponding ot subjects in `jena-model`
interpret-binding-elementclj
(interpret-binding-element elt)Returns a KWI or literal value as appropriate to elt
Where
eltis bound to some variable in a query posed to a jena model.
Returns a KWI or literal value as appropriate to `elt` Where - `elt` is bound to some variable in a query posed to a jena model.
make-jena-graphclj
(make-jena-graph)(make-jena-graph model)(make-jena-graph ds kwi)Returns an implementation of igraph using a model or a named model in ds named kwi
Where
modelis a jena model (optional; default is a jena default model)dsis a jena dataset to which we will declare a graph name withkwikwiis a keyword identifier translatable to the URI of a named graph inds
Returns an implementation of igraph using a `model` or a named model in `ds` named `kwi` Where - `model` is a jena model (optional; default is a jena default model) - `ds` is a jena dataset to which we will declare a graph name with `kwi` - `kwi` is a keyword identifier translatable to the URI of a named graph in `ds`
make-statementclj
(make-statement s p o)Returns a Jena Statment for s p and o
Returns a Jena Statment for `s` `p` and `o`
query-jena-modelclj
(query-jena-model g q)(query-jena-model query-op g q)Returns (binding-map, ...) for q posed to g using query-op
Where
binding-map:= {varvalue, ...}qis a SPARQL querygis a jena modelquery-opis the jena query operation (optional. defualt is #(.execSelect %)varis a keyword corresponding to a variable inqvalueis an interpretation of the value bound tovarthis will be either a KWI or a literal, as appropriate.
Returns (`binding-map`, ...) for `q` posed to `g` using `query-op`
Where
- `binding-map` := {`var` `value`, ...}
- `q` is a SPARQL query
- `g` is a jena model
- `query-op` is the jena query operation (optional. defualt is #(.execSelect %)
- `var` is a keyword corresponding to a variable in `q`
- `value` is an interpretation of the value bound to `var`
this will be either a KWI or a literal, as appropriate.
read-rdfclj
(read-rdf rdf-file)Returns g for rdf-file
Where
gis an igraphrdf-fileis an io/file in one of the RDF formats
Returns `g` for `rdf-file` Where - `g` is an igraph - `rdf-file` is an io/file in one of the RDF formats
write-rdfclj
(write-rdf g target fmt)(write-rdf g target fmt base)Side-effect: writes contents of g to target in fmt
Where
gis a jena igraphtargetnames a filefmtnames an RDF fmt, e.g. 'Turtle'base(optional) isthe base URI of any relative URIs. Default is nil.
Side-effect: writes contents of `g` to `target` in `fmt` Where - `g` is a jena igraph - `target` names a file - `fmt` names an RDF fmt, e.g. 'Turtle' - `base` (optional) isthe base URI of any relative URIs. Default is nil.
