Introduction to the WUMM RDFData Subproject

• More about the General TRIZ Ontology Project

We assume that you are familiar with the basic RDF concepts. Our RDF data project consists of several areas

• Area of TRIZ activities (people, conferences, presentations, certificates)
• Area of TRIZ knowledge resources (TRIZ Body of Knowledge, TRIZ books)
• Area of TRIZ ontology (accompanying the TRIZ Ontology Project)

Detailed explanations of our modelling concepts can be found in the following publications:

• Hans-Gert Gräbe: Towards a Linked Open Data TRIZ Ontology. LIFIS Online, August 13, 2021. Accepted for Presentation at the TRIZ Future Conference 2021.
• Hans-Gert Gräbe: About the WUMM modelling concepts of a TRIZ ontology (pdf). Manuscript, April 2021.
• Tom Strempel, Hans-Gert Gräbe: Semantic Web Modelling of TRIZ System Evolution Concepts (pdf). Accepted for Presentation at the TRIZFest 2021.

Our RDF datasets can be found in the RDFData repo. For presentation and inspection of the data we run

• a Virtuoso based RDF Data Store with a SPARQL endpoint and
• a prototypical presentation site.

On this page the general settings are briefly described.

General Settings

1. URI and namespaces: For our own modelling we use the overall namespace prefix http://opendiscovery.org/rdf/.

2. Multilanguage concepts: RDF defines a generic concept to provide different language versions of Literals using standard language tags (en - English, de - German, ru - Russian). We use this concept to compile multilingual versions of different RDF graphs.

3. Naming Conventions: RDF graphs and the corresponding file names usually are in plural mode, the namespace prefix of the different instances described in this graph is in singular mode.

Another standard uses the prefix The to distiguish the names of the graph and the namespace prefix used for the instances described in this graph.

This avoids name clashes between the name of the graph and the names of the instances described within that graph.

4. Blank nodes: We do not use blank nodes since they are valid only locally within the graph thus complicating the resolution of references and refactorization.

Namespaces

We use the following project specific name spaces

• od: http://opendiscovery.org/rdf/Model# - the namespace of the WUMM model ontology
• tc: http://opendiscovery.org/rdf/Concept/ - the namespace for TRIZ concepts
• odp: http://opendiscovery.org/rdf/Person/ - the namespace for TRIZ people

and the following standard ontologies

• bibo: http://purl.org/ontology/bibo/ (bibliographical information)
• cc: http://creativecommons.org/ns# (licensing information)
• dcterms: http://purl.org/dc/terms/ (dublin core metadata)
• foaf: http://xmlns.com/foaf/0.1/ (people ontology)
• ical: http://www.w3.org/2002/12/cal/ical# (calendar ontology)
• skos: http://www.w3.org/2004/02/skos/core# (knowledge meta ontology)
• swc: http://data.semanticweb.org/ns/swc/ontology# (conferences ontology)

Organization of the RDF Graphs in Files

Different data is collected in different RDF Graphs in Turtle format. Each such graph http://opendiscovery.org/rdf/XXX is stored in a file XXX.ttl and described by an owl:Ontology object within this file.
