The Data Web and PLM

519 views

Published on

The Web is until now mostly considered to be a Web of documents, more specifically a Web of HTML pages. However, the inventor of the Web Tim Berners Lee considers the Web not to have reached its fullest potential. The Data Web and Linked Data will enable more precise search services transforming the Web into a smarter and richer Web. Google for example uses Linked Data concepts to realize its own knowledge graph to process voice commands and voice queries for users. Linked Data concepts are not limited to the public Web. They can also be used to capture private knowledge in private company Webs making them potentially applicable as the backbone for future PLM solutions.

  36. 36. Converting Existing Schemas Into RDF 36
  37. 37. Traditional Schema Schema XML Document Schema describes the structure of an XML document The purpose of an XML Schema is to define the legal building blocks of an XML document: ● the elements and attributes that can appear in a document ● the number of (and order of) child elements ● data types for elements and attributes ● default and fixed values for elements and attributes 37 <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="requirement"> <xs:complexType> <xs:sequence> <xs:element name="identifier" type="xs:string"/> <xs:element name="description" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> <requirement> <identifier>123</identifier> <description>X shall Y</description> </requirement>
  38. 38. Converting Schema into RDF Schema RDF Schema 38 <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="requirement"> <xs:complexType> <xs:sequence> <xs:element name="identifier" type="xs:string"/> <xs:element name="description" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> ?
  39. 39. Converting Schema types into RDF Schema element type RDF Resource Type 39 <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="requirement"> <xs:complexType> <xs:sequence> <xs:element name="identifier" type="xs:string"/> <xs:element name="description" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> <rdfs:Class rdf:about="http://open-services.net/ns /rm#Requirement"> <rdfs:label xml:lang="en-GB">Requirement</rdf s:label> </rdfs:Class>
  40. 40. Converting Schema properties into RDF Schema element property (e.g. of type String) RDF Resource property 40 <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="requirement"> <xs:complexType> <xs:sequence> <xs:element name="identifier" type="xs:string"/> <xs:element name="description" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> <rdf:Description rdf:about="http://purl.org/dc/terms/ide ntifier"> <rdfs:label xml:lang="en">Identifier</rdfs:label> </rdf:Description>
  41. 41. Converting Schema property multiplicities into RDF Schema element property multiplicity (e.g. identifier must occur once and only, default value in XSD for minOccurs and maxOccurs is 1 ) RDF Resource property 41 <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="requirement"> <xs:complexType> <xs:sequence> <xs:element name="identifier" type="xs:string"/> <xs:element name="description" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> <oslc:Property> <oslc:propertyDefinition rdf:resource="http://purl.org/dc/terms/ identifier"/> <oslc:occurs rdf:resource="http://open-service.net/ ns/core#Exactly-one"/> </oslc:Property>

  43. 43. „Universal“ specs vs Web specs „Universal“ Standards Web Standards Example SysML/STEP OSLC Specifications Scope Large (Example SysML: approx. 300 concepts) Minimalistic (Example OSLC RM Spec: 2 concepts) Effort until release High Small Time until release Long Short Ease of implementation Difficult Easy Ease of adoption Difficult Easy 43
