NAME

     sord_validate — validate RDF data

SYNOPSIS

     sord_validate [-hlv] input ...

DESCRIPTION

     sord_validate 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 a
     validation "error" here doesn't necessarily mean that data is invalid, since it isn't, for
     example, required to explicitly list types in RDF.  This validator implements a more strict
     and explicit set of rules, based on the realistic needs of simple real-world
     implementations.  For example, missing explicit type information may be warned about, even
     though even a simple inference engine would be able to deduce it.

     sord_validate never retrieves data from the web or special places on the file system, it
     only processes the 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 ranges (xsd:minimumInclusive and
     xsd:maximumInclusive).  Given an appropriate schema, this is enough to validate against most
     of the standard XSD datatypes.

     The options are as follows:

     -h   Print the command line options.

     -l   Print errors on a single line.

     -v   Display version information and exit.

EXIT STATUS

     sord_validate exits with a status of 0 if the input data is valid, or non-zero if there are
     issues with the data or if an error occurred.
