.SH NAME
rdfproc \- Redland RDF processor utility
.SH SYNOPSIS
.B rdfproc
.RB [ options ]
.IR "store-name"
.IR "command"
.IR "arg..."
.SH EXAMPLE
.nf
.B rdfproc test parse http://planetrdf.com/guide/rss.rdf

.B rdfproc test serialize ntriples

.SH DESCRIPTION
The
.B rdfproc
utility allows parsing, querying, manipulating and  serializing of
RDF content using the
.B Redland
RDF library.   The \fIstore-name\fR is a Redland store name, typically
a short identifier.  The arguments to \fIcommand\fR vary
and are explained in section COMMANDS below.
.SH OPTIONS
rdfproc uses the usual GNU command line syntax, with long
options starting with two dashes (`-') if supported by the
getopt_long function.  Otherwise the short options are only available.
.TP
.B \-h, \-\-help
Show a summary of the options.
.TP
.B \-c, \-\-contexts
Use a store with Redland contexts.
.TP
.B \-n, \-\-new
Make a new store, overwriting any existing one.
.TP
.B \-o, \-\-output \fIFORMAT\fR
Set the output FORMAT for sequences of triples, such as from a search
(find command) to a Redland serializer.  At present the alternatives
are  'simple' (the default one if this option is omitted), 'ntriples'
or 'rdfxml'.
.TP
.B \-p, \-\-password
Read the storage option 'password' from standard input.  Terminated
by end of line ('\\n') or end of file.  This is equivalent
to setting it using \-t or \-\-storage-options but does not
require exposing the password in the argument list.
.TP
.B \-s, \-\-storage \fITYPE\fR
Set the Redland storage type (default 'hashes').  Alternatives
are 'memory' which is always present
and '3store', 'file', 'mysql', 'sqlite', 'uri' when support for those
is compiled in If environment variable RDFPROC_STORAGE_TYPE is set,
the storage type given here will override it.
.TP
.B \-t, \-\-storage-options \fIOPTIONS\fR
Set options for the the Redland storage, default is "hash-type='bdb',dir='.'"
to match the default storage "hashes".  For storages types such as 'mysql'
that need extra options this would typically be something
like "host='hostname',database='dbname',user='abc',password='pass'".
If environment variable RDFPROC_STORAGE_OPTIONS is set, the storage
options given here will be applied afterwards.
.TP
.B \-v, \-\-version
Print the Redland version and exit.
.SH COMMANDS
Where a node is allowed, such as \fINODE\fP, \fISUBJECT\fP,
\fIPREDICATE\fP or \fIOBJECT\fP below, simple heuristics are used to
guess which are blank node identifiers, URIs or literals
(to add a statement with a literal, use add-typed).  If the
item starts with _: then it is assumed to be a blank node identifier,
otherwise if it matches something:// it is assumed to be a URI,
otherwise it is a literal.  Literals are only allowed as objects
of statements and blank nodes are not allowed as predicates.
.IP "\fBadd \fISUBJECT\fP \fIPREDICATE\fP \fIOBJECT\fP \fI[CONTEXT]\fP\fR"
Add the given triple to graph, in the optional Redland context
if the \fICONTEXT\fR node is given.

.IP "\fBadd-typed \fISUBJECT\fP \fIPREDICATE\fP \fIOBJECT\fP \fIOBJECT-LANG\fP \fIOBJECT-URI\fP \fI[CONTEXT]\fP\fR"
Add the triple with the datatyped literal object to the graph, in the
optional Redland context if \fICONTEXT\fR is given.

.IP "\fBarc \fISUBJECT\fP \fIOBJECT\fP\fR"
.IP "\fBarcs \fISUBJECT\fP \fIOBJECT\fP\fR"
Show one node/all nodes that match triples (\fISUBJECT\fP, ?, \fIOBJECT\fP)

.IP "\fBarcs-in \fINODE\fP\fR"
Show all properties of triples with \fINODE\fP as a subject.

.IP "\fBarcs-out \fINODE\fP\fR"
Show all properties of triples with \fINODE\fP as an object.

.IP "\fBcontains \fISUBJECT\fP \fIPREDICATE\fP \fIOBJECT\fP\fR"
Check if the given triple is in the graph.

.IP "\fBcontexts\fR"
List all the contexts in the graph (if contexts are enabled).

.IP "\fBfind \fISUBJECT\fP|- \fIPREDICATE\fP|- \fIOBJECT\fP|- [\fICONTEXT\fP]\fR"
Find matching triples to the given statement
where - stands for a blank that matches any node.  If \fICONTEXT\fP
is given, only search for triples in that context node.

.IP "\fBhas-arc-in \fINODE\fP \fIARC\fP\fR"
Check that there is a triple with \fINODE\fP as a subject
and \fIARC\fP as a predicate.

.IP "\fBhas-arc-out \fPNODE\fP \fIARC\fP\fR"
Check that there is a triple with \fINODE\fP as a object
and \fIARC\fP as a predicate.

.IP "\fBparse \fIURI|FILENAME\fP [\fISYNTAX|\fP [\fIBASE URI\fP]]\fR"
Parse syntax at \fIURI\fP into the graph using \fISYNTAX\fP which
can be one of \fIrdfxml\fP (RDF/XML, default), \fIntriples\fP, \fIturtle\fP,
\fIrss-tag-soup\fP (for all RSS and Atoms), \fIgrddl\fP and \fIguess\fP to
use content hints and protocol information to work it out. (This list changes
faster than this manual page)
If \fIFILENAME\fP is a existing file, the appropriate URI will be
generated for it.

.IP "\fBparse-stream \fIURI|FILENAME\fP [\fISYNTAX\fP [\fIBASE URI\fP [\fICONTEXT\fP]]\fR"
Streaming parse syntax at URI into the graph using \fISYNTAX\fP which
can be one of \fIrdfxml\fP (RDF/XML, default) or \fIntriples\fP.
If \fIFILENAME\fP is an existing file, the appropriate URI will be
generated for it.  If the optional \fICONTEXT\fI URI is given,
the triples are added to that context.

.IP "\fBprint\fR"
Print the graph triples in a simple format showing context nodes
if present.

.IP "\fBquery \fINAME\fP|- \fIURI\fP|- \fIQUERY-STRING\fP\fR"
Run \fIQUERY-STRING\fI query in language \fINAME\fR returning
variable bindings, a boolean or RDF graph depending on the query.
Query language can be 'sparql' or 'rdql'.

.IP "\fBremove \fISUBJECT\fP \fIPREDICATE\fP \fIOBJECT\fP \fI[CONTEXT]\fP\fR"
Remove the given triple graph, in the optional Redland context
if \fICONTEXT\fR is given.

.IP "\fBremove-context \fICONTEXT\fP\fR"
Remove all triples in the graph with the Redland context \fICONTEXT\fR.

.IP "\fBserialize [\fISYNTAX\fP [\fIURI\fP [\fIMIME-TYPE\fP]]]\fR"
Serializes the graph to a syntax with a particular \ISYNTAX\fI
\fIURI\fR or Internet Media Type/MIME Type.  The default is
RDF/XML (\fINAME\fR "rdfxml", MIME Type "application/rdf/xml")
if none of the above are given.  Other alternatives
are "ntriples" (no MIME Type).

.IP "\fBsource \fIPREDICATE\fP \fIOBJECT\fP\fR"
.IP "\fBsources \fIPREDICATE\fP \fIOBJECT\fP\fR"
Show one node/all nodes that match triples (?, \fIPREDICATE\fP, \fIOBJECT\fP)

.IP "\fBtarget \fISUBJECT\fP \fIPREDICATE\fP\fR"
.IP "\fBtargets \fISUBJECT\fP \fIPREDICATE\fP\fR"
Show one node/all nodes that match triples (\fISUBJECT\fP, \fIPREDICATE\fP, ?)

.SH "ENVIRONMENT"
RDFPROC_STORAGE_OPTIONS can be set to provide storage options
instead of using the option \-t, \-\-storage-options \fIOPTIONS\fR.
When both are given, command options are applied last.
.LP
RDFPROC_STORAGE_TYPE can be set to provide a storage type
instead of using the option \-s, \-\-storage \fITYPE\fR.
When both are given, the storage type from the command is used.
