SERD-VALIDATE 1 +.Os Serd +.Sh NAME +.Nm serd-validate +.Nd validate RDF data +.Sh SYNOPSIS +.Nm serd-validate +.Op Fl hVv +.Op Fl B Ar base +.Op Fl I Ar syntax +.Op Fl W Ar checks +.Op Fl X Ar checks +.Op Fl k Ar bytes +.Op Fl s Ar schema +.Ar input ... +.Sh DESCRIPTION +.Nm +validates RDF data against one or more RDFS or OWL schemas. +Unlike other serd tools, +.Nm +does not write any data, +it only prints messages and returns a status that indicates whether the data is valid. +.Pp +All inputs to check must be given as an +.Ar input . +Schemas can also be given as an +.Ar input , +in which case they will also be checked for issues. +Alternatively, schemas can be given using the +.Fl s +option, which will load the schema to check against, +but not initiate checks for schema statements themselves. +This roughly means that error messages will not be printed for the schema files, +although some may still appear if they are related to issues in the input files. +When using schemas in this way, it is highly recommended to ensure that the schemas are valid first, +otherwise the validator may not work correctly. +.Pp +The options are as follows: +.Pp +.Bl -tag -compact -width 3n +.It Fl B Ar base +Base URI or path. +See +.Xr serd-pipe 1 +for details. +.Pp +.It Fl I Ar syntax +Input syntax or option: +.Cm NQuads , +.Cm NTriples , +.Cm TriG , +.Cm Turtle , +.Cm lax , +.Cm variables , +.Cm relative , +or +.Cm labels . +See +.Xr serd-pipe 1 +for details. +.Pp +.It Fl W Ar checks +Warn about any issues found by the given +.Ar checks , +which is a regular expression that matches a set of check names to enable, +or a special name for standard sets of checks: +.Bl -tag -width 3n +.It Cm all +Enables all checks that should pass on typical well-formed data. +.It Cm everything +Enables all the checks of +.Cm all , +along with additional strict checks that are useful for making data simpler and more explicit. +.El +.Pp +See +.Sx CHECKS +below for a detailed list of all checks. +.Pp +.It Fl X Ar checks +Exclude +.Ar checks +from the set of checks enabled by a previous +.Fl W +option. +This is typically used after +.Fl W Cm all +or +.Fl W Cm everything +to suppress a few specific checks. +.Pp +.It Fl V +Display version information and exit. +.Pp +.It Fl h +Print the command line options. +.Pp +.It Fl k Ar bytes +Parser stack size. +See +.Xr serd-pipe 1 +for details. +.Pp +.It Fl s Ar schema +Schema input file. +The schema will be loaded like an input, +but into a separate graph that is not checked for issues. +.Pp +.It Fl v +Print verbose messages about loaded resources. +.El +.Sh CHECKS +.Bl -tag -compact -width 3n +.It Cm allValuesFrom +Checks that all properties with owl:allValuesFrom restrictions have valid value types. +.It Cm anyUri +Checks that the value of any property with range xsd:anyURI is a URI. +.It Cm cardinalityEqual +Checks that any instance of a class with a owl:cardinality property restriction has exactly that many values of that property. +.It Cm cardinalityMax +Checks that any instance of a class with a owl:maxCardinality property restriction has no more than that many values of that property. +.It Cm cardinalityMin +Checks that any instance of a class with a owl:minCardinality property restriction has at least that many values of that property. +.It Cm classCycle +Checks that no class is a sub-class of itself, recursively. +This ensures that the graph is acyclic with respect to rdfs:subClassOf. +If this check fails, all further checks are aborted. +.It Cm classLabel +Checks that every rdfs:Class has an rdfs:label. +.It Cm datatypeCycle +Checks that no datatype is a sub-datatype of itself, recursively. +This ensures that the graph is acyclic with respect to owl:onDatatype. +If this check fails, all further checks are aborted. +.It Cm datatypeProperty +Checks that datatype properties have literal (not instance) values. +.It Cm datatypeType +Checks that every datatype is defined as a rdfs:Datatype. +.It Cm deprecatedClass +Checks that there are no instances of deprecated classes. +.It Cm deprecatedProperty +Checks that there are no uses of deprecated properties. +.It Cm explicitInstanceType +Checks that every instance explicitly has every type required of it. +This is a (often overly) strict check that assumes a closed world and requires every instance to explicitly have the type(s) required of it. +.It Cm functionalProperty +Checks that no instance has several values of a functional property. +.It Cm instanceLiteral +Checks that there are no instances where a literal is expected. +.It Cm instanceType +Checks that every instance with an explicit type matches that type. +This is a broad check that triggers other type-related checks, but mainly it will check that every instance of a class conforms to any restrictions on that class. +.It Cm inverseFunctionalProperty +Checks that at most one instance has a given value of an inverse functional property. +.It Cm literalInstance +Checks that there are no literals where an instance is expected. +.It Cm literalMaxExclusive +Checks that literal values are not greater than or equal to any applicable xsd:maxExclusive datatype restrictions. +.It Cm literalMaxInclusive +Checks that literal values are not greater than any applicable xsd:maxInclusive datatype restrictions. +.It Cm literalMinExclusive +Checks that literal values are not less than or equal to any applicable xsd:minExclusive datatype restrictions. +.It Cm literalMinInclusive +Checks that literal values are not less than any applicable xsd:minInclusive datatype restrictions. +.It Cm literalPattern +Checks that literals with xsd:pattern restrictions match the regular expression pattern for their datatype. +.It Cm literalRestriction +Checks that literals with supported restrictions conform to those restrictions. +This is a high-level check that triggers the more specific individual literal restriction checks. +.It Cm literalValue +Checks that literals with supported XSD datatypes are valid. +The set of supported types is the same as when writing canonical forms. +.It Cm objectProperty +Checks that object properties have instance (not literal) values. +.It Cm plainLiteralDatatype +Checks that there are no typed literals where a plain literal is expected. +A plain literal may have an optional language tag, but not a datatype. +.It Cm predicateType +Checks that every predicate is defined as an rdf:Property. +.It Cm propertyCycle +Checks that no property is a sub-property of itself, recursively. +This ensures that the graph is acyclic with respect to rdfs:subPropertyOf. +If this check fails, all further checks are aborted. +.It Cm propertyDomain +Checks that any instance with a property with an rdfs:domain is in that domain. +.It Cm propertyLabel +Checks that every rdf:Property has an rdfs:label. +.It Cm propertyRange +Checks that the value for any property with an rdfs:range is in that range. +.It Cm someValuesFrom +Checks that instances of classes with owl:someValuesFrom property restrictions have at least one matching property value. +.El +.Sh EXIT STATUS +.Nm +exits with a status
