Introduction

I had been doing a lot of work using librdf and wanted a way to easily browse tablular results of queries.

So I wrote this.

Prefixes

There's a few magics to manipulate a dictionary of default prefixes that will be added to sparql queries.

%lsns

show the list of current prefix to url mappings

%addns prefix url

defines prefix for the specified url. this is equivalent to having done PREFIX prefix: <url> at the start of your sparql query. (Other than the prefixes are also used to shorten output.

%delns prefix

removes a prefix from the dictionary of default prefixes

%%sparql

issues a sparql query. Providing at least a model or a source is required.

-m --model <arg>

specify model variable to run query against. If no model is set, it will use a new temporary memory model

-s --source <arg>

add source url to pre-load data from.

-o --output <arg>

specify variable to store result of query in

-c --count

display how many triples were returned

%load_source [source]*

load a list of sources into a model

-m --model <arg>

model name to store triples in

source

list of locations to load triples from

%save_model filename

serialize model in filename

-m --model

model to store.

-f --format

format to serialize model in (turtle, rdf/xml, etc)
