Benefits of Semantics
• Claim: S2S leverages semantics to provide a metadata vocabulary, and, in future versions, will use linked data practices for dereferenceable framework metadata.

Benefit of Semantics
• Claim: S2S provides explicit semantics for the relationships between web services, search parameters, and user interface widgets.

Benefit of Semantics

Benefit of Semantics
• Claim: S2S leverages RDFS reasoning to infer sub-class transitivity for type checking, and, in future versions, will use OWL-DL to perform instance integrity checking using cardinality and value qualifiers.

Benefit of Semantics
• For integrity checking…– …In component registration/validation
• OpenSearchService hasDescriptionDocument exactly 1 xsd:anyURI
• Widget hasGeneratorFunction exactly 1 xsd:string
– …In real-time user interface building• HierarchicalWidget forWidget only OrdinalParameter
• For sub-class reasoning…– …To answer queries like “select all widgets” when
many widgets are not directly classified as type s2s:Widget

Questions from Class
• Jin: See slides 8, 10, and 12• Peter:
– Claim 1: Vocabulary and metadata are not Semantic Web terms. For an explanation of linked data see: http://bit.ly/PmwsA
– Claim 2: Semantics is also not a Semantic Web term. Basically, I provide a directed graph where the vertices denote concepts and the arcs denote relationships between concepts in the framework. See: http://bit.ly/ebKcRV
– Claim 3: See slide 12

Questions from Class
• Scott: S2S uses only lightweight semantics. Basically:– Structured metadata– Explicit semantics– Automated integrity checking– …propose alternative solution for reusable user
interface and a federated search platform that spans web service standards?
• Ping: Swoogle searches for ontologies, S2S is a search platform. Yes, I created the metadata.
