+.TH SORD_VALIDATE 1 "21 Mar 2012"
+
+.SH NAME
+.B sord_validate \- Validate RDF data
+
+.SH SYNOPSIS
+sord_validate [OPTION]... INPUT...
+
+.SH OPTIONS
+.TP
+\fB\-h\fR
+Print the command line options.
+
+.TP
+\fB\-l\fR
+Print errors on a single line.
+
+.TP
+\fB\-v\fR
+Display version information and exit.
+
+.SH DESCRIPTION
+This is a simple validator which checks that all used properties are actually
+defined, and that the domain and range of properties is explicitly correct.
+Note that an "error" from this program does not necessarily mean data is
+invalid, since it is not required to explicitly list types in RDF, however it
+is a good idea to do so.
+
+This program never retrieves data from the web or magical places on the file
+system, it only processes files passed directly on the command line.  This
+means you must pass all used vocabularies to get a useful result.
+
+If an appropriate schema is available, literals are checked against datatype
+definitions (both the explicit datatype of the literal itself as well as any
+types implied by the corresponding property).  Three XML Schema Datatypes (XSD)
+constraints are currently supported: regular expressions (xsd:pattern), and
+inclusive range (xsd:minimumInclusive and xsd:maximumInclusive).  Given an
+appropriate schema, this is enough to validate against most of the standard XSD
+datatypes.
+
+.SH EXAMPLES
+sord_validate `find ~/schemas/ -name '*.ttl'` data.ttl
