When referring more generally, OWL Family will be used.

In 2005, at the OWL Experiences And Directions Workshop a consensus formed that recent advances in description logic would allow a more expressive revision to satisfy user requirements more comprehensively whilst retaining good computational properties.

It was hoped that it would be simpler to provide tool support for OWL Lite than its more expressive relatives, allowing quick migration path for systems utilizing thesauri and other taxonomies.

In practice, however, most of the expressiveness constraints placed on OWL Lite amount to little more than syntactic inconveniences: most of the constructs available in OWL DL can be built using complex combinations of OWL Lite features.

RDF, OWL, meta-data are all schemes to try to hoard information about information and so require more information to be created and " managed.

Samuel John Gurney Hoare, 1st Viscount Templewood GCSI, GBE, CMG, PC, OWL ( 24 February 1880 – 7 May 1959 ), more commonly known as Sir Samuel Hoare, was a senior British Conservative politician who served in various Cabinet posts in the Conservative and National governments of the 1920s and 1930s.

In the future, tools based on semantic web languages such as Resource Description Framework ( RDF ), the Web Ontology Language ( OWL ) and standardized metadata registry will make data mapping a more automatic process.

Many RDFS components are included in the more expressive language Web Ontology Language ( OWL ).

OWL Full allows an ontology to augment the meaning of the pre-defined ( RDF or OWL ) vocabulary.

OWL Full is intended to be compatible with RDF Schema ( RDFS ), and to be capable of augmenting the meanings of existing Resource Description Framework ( RDF ) vocabulary.

FOAF is a descriptive vocabulary expressed using the Resource Description Framework ( RDF ) and the Web Ontology Language ( OWL ).

Brown's GUIDE ( marketed by OWL and released earlier that year ) and Brown University's Intermedia, led to broad interest in and enthusiasm for databases and new media.

It involves publishing in languages specifically designed for data: Resource Description Framework ( RDF ), Web Ontology Language ( OWL ), and Extensible Markup Language ( XML ).

Many of the techniques mentioned here will require extensions to the Web Ontology Language ( OWL ) for example to annotate conditional probabilities.

This submission was the starting point for the language ( later called OWL ) to be developed by W3C's web ontology working group, WebOnt.

One of the most recent is the Web Ontology Language ( OWL ) ( but ontologies are a very specialized kind of metadata, and OWL has no built-in support for most of the information represented in UML ).

The Overwhelmingly Large Telescope ( OWL ) was a conceptual design by the European Southern Observatory ( ESO ) organization for an extremely large telescope, which was intended to have a single aperture of 100 meters in diameter.

All proposed designs for the OWL are variations on a segmented mirror, since there is no technology available to build a monolithic 60-or 100-meter mirror.

Experience gained in existing segmented mirrors ( for example, the Keck telescope ) suggests that the mirror proposed for the OWL is feasible.

Among these, the Norwegian highest civilian award Medal for Outstanding Civic Service ( Medaljen for borgerdåd ) ( 1966 ), the Grand Cross of the Order of Dannebrog ( 1954 ) and Grand Cross of the Order of St. Olav ( 1953 ), Czechoslovak OWL ( 1948 ).

The Web Ontology Language ( OWL ) is a family of knowledge representation languages for authoring ontologies.

The natural acronym for Web Ontology Language would be WOL instead of OWL.

Development of OWL Lite tools has thus proven almost as difficult as development of tools for OWL DL, and OWL Lite is not widely used.

OWL DL includes all OWL language constructs, but they can be used only under certain restrictions ( for example, number restrictions may not be placed upon properties which are declared to be transitive ).

OWL Full is undecidable, so no reasoning software is able to perform complete reasoning for it.

for languages in the OWL family.

Each leads to a syntax for languages in the OWL family through this mapping.

Languages in the OWL family are capable of creating classes, properties, defining instances and its operations.

Languages in the OWL family support various operations on classes such as union, intersection and complement.

In OWL, all classes start with letter " T " ( e. g. TApplication ); there are several root classes, the most common is TWindow from which window classes ( e. g. TFrameWindow, TDecoratedFrameWindow, TDialog, TInputDialog, TFileOpenDialog, etc.

Many other logic-based languages could also be defined as subsets of CL by means of similar translations ; among them are the RDF and OWL languages, which have been defined by the W3C.

Topic Maps are a form of semantic web technology, and some work has been undertaken on interoperability between the W3C's RDF / OWL / SPARQL family of semantic web standards and the ISO's family of Topic Maps standards.

For example, the URI http :// www. w3. org / TR / 2004 / REC-owl-guide-20040210 / wine # Merlot is intended by its owners to refer to the class of all Merlot red wines by vintner ( i. e., instances of http :// www. w3. org / TR / 2004 / REC-owl-guide-20040210 / wine # Merlot each represent the class of all wine produced by a single vintner ), a definition which is expressed by the OWL ontology — itself an RDF document — in which it occurs.

Being based upon first-order logic, knowledge expressed using one variant of OWL can be logically processed, i. e., inferences can be made upon it.

Significant progress has also been made in bringing the world of UML modeling and the Semantic Web together through the adoption of the Ontology Definition Metamodel which relates UML models in a standard way with RDF and Web Ontology Language ( OWL ) models.

RDF, OWL, and XML, by contrast, can describe arbitrary things such as people, meetings, or airplane parts.

Much of the work in DAML has now been incorporated into OWL.

As RDFS and OWL demonstrate, additional ontology languages can be built upon RDF.

Object Windows Library ( OWL ) was released to compete with MFC, and offered a similar object-oriented wrapper.

The OWL could be expected to regularly see astronomical objects with an apparent magnitude of 38 ; or 1, 500 times fainter than the faintest object which has been detected by the Hubble Space Telescope.

Recent developments in KR include the concept of the Semantic Web, and development of XML-based knowledge representation languages and standards, including Resource Description Framework ( RDF ), RDF Schema, Topic Maps, DARPA Agent Markup Language ( DAML ), Ontology Inference Layer ( OIL ), and Web Ontology Language ( OWL ).

Development of the Semantic Web, has included development of XML-based knowledge representation languages and standards, including RDF, RDF Schema, Topic Maps, DARPA Agent Markup Language ( DAML ), Ontology Inference Layer ( OIL ), and Web Ontology Language ( OWL ).

Many XML-based applications now exist, including Resource Description Framework ( RDF ), XForms, DocBook, SOAP and the Web Ontology Language ( OWL ).

* Web Ontology Language ( OWL ), a family of knowledge representation languages

In Semantic Web languages, such as Resource Description Framework ( RDF ) and Web Ontology Language ( OWL ), a statement is a binary relation.

OWL DL was designed to provide the maximum expressiveness possible while retaining computational completeness ( either φ or ¬ φ belong ), decidability ( there is an effective procedure to determine whether φ is derivable or not ), and the availability of practical reasoning algorithms.

The Object Windows Library ( OWL ), designed for use with Borland's Turbo C ++ compiler, was a competing product introduced by Borland around the same time.

OWL applications supports ( non-exhaustive list ) Single / Multiple Document Interface ( SDI / MDI ), Doc & View Document Model, Drag & Drop, print and print-preview, GDI encapsulation, Windows Help ( Winhelp ), mail and messaging ( MAPI ), Internet ( OwlSock / WinSock ), OLE 1. 0 and OLE 2. 0 and other features.
