http_login(+Request)[private]

HTTP handler to associate the current session with a local user. If the login succeeds a 200 reply according to the resultFormat parameters is sent. If the result fails due to a wrong user/password, the server responds with a 403 (forbidden) message. Other failures result in a 500 (server error).

See also: - help('howto/ClientAuth.txt') for additional information on authetication.

http_logout(+Request)[private]

HTTP handler to logout current user.

evaluate_query(+Request) is det[private]

HTTP handler for both SeRQL and SPARQL queries. This handler deals with interactive queries. Machines typically access /sparql/ to submit queries and process result compliant to the SPARQL protocol.

evaluate_graph_query(+Request)[private]

Handle CONSTRUCT queries.

evaluate_table_query(+Request)[private]

Handle SELECT queries.

compile(+Language, +Query, -Compiled, +Options)[private]

Compile a query and validate the query-type

run(+Language, +Compiled, -Reply)[private]

extract_rdf(+Request)[private]

HTTP handler to extract RDF from the database. This handler separates the data into schema data and non-schema data, where schema data are triples whose subject is an rdfs:Class or rdf:Property. By default both are off, so one needs to pass either or both of the schema and data options as on.

export_triple(+Schema, +Data, +ExplicitOnly, -RDF)[private]

list_repositories(+Request)[private]

List the available repositories. This is only default for now

clear_repository(+Request)[private]

Clear the repository.

unload_source(+Request)[private]

Remove triples loaded from a specified source

unload_graph(+Request)[private]

Remove a named graph.

flush_journal(+Request)[private]

Flush the journal of the requested graph

modify_persistency(+Request)[private]

Change the persistent properties for the requested graph

upload_data(Request)[private]

Sesame compliant method to upload data to the repository, typically used to handle a POST-form from a web-browser (e.g., Load local file in the ClioPatria menu). If dataFormat is omitted, the format of the data is guessed from the data itself. Currently, this possitively identifies valid RDF/XML and assumes that anything else is Turtle.

create_tmp_file(+Stream, -Out, +Options) is det[private]

Called from library(http/http_multipart_plugin) to process uploaded file from a form.

Arguments:

`Stream`	- is the input stream. It signals EOF at the end of the part, but must not be closed.
`Options`	- provides information about the part. Typically, this contains `filename(FileName)` and optionally `media(Type, MediaParams)`.

upload_data_file(+Request, +FormData, +TempFile, +FileOptions)[private]

Load RDF from TempFile with additional form data provided in FormData. Options are the options passed from the uploaded file and include filename(Name) and optionally media(Type, Params).

upload_url(+Request)[private]

Load data from an HTTP server. This API is compatible to Sesame, although the verifyData option is not implemented (data is always checked for syntax). Unlike Sesame, the default format is not rdfxml, but derived from the Content-type reported by the server.

See also: - Calls rdf_load/2 for the actual loading.; - load_url_form/1 a form to access this API

ssl_verify(+SSL, +ProblemCert, +AllCerts, +FirstCert, +Error)[private]

Currently we accept all certificates. We organise our own security using SHA1 signatures, so we do not care about the source of the data.

remove_statements(+Request)[private]

Remove statements from the database

remove_triples(+List)[private]

Remove indicated triples from the database.

rdf_ntriple_part(+Type, -Value)//[private]

Parse one of the fields of an ntriple. This is used for the SWI-Prolog Sesame (rdf4j.org) implementation to realise /servlets/removeStatements. I do not think public use of this predicate should be stimulated.

add_prefix(+Request)[private]

attribute_decl(+OptionName, -Options)[private]

Default options for specified attribute names. See http_parameters/3.

result_format(+Request, ?Format) is det[private]

api_action(+Request, :Goal, +Format, +Message)

Perform some -modifying- goal, reporting time, triples and subject statistics.

Arguments:

`Format`	- specifies the result format and is one of `html`, `xml` or `rdf`.
`Message`	- is passed to html_write//1.

result_table(+CPU, +SubDiff, +TripleDiff)// is det[private]

HTML component that summarises the result of an operation.

authorized_api(+Action, +ResultFormat) is det[private]

Errors: - permission_error(http_location, access, Path)
