Unlike a relational database, a triplestore is optimized for the storage and retrieval of triples. Triplestore Much like a relational database, one stores information in a triplestore and retrieves it via a query language. Storing a (conceptually) “cached” version of the generated RDF, instead of referring to the live service, might also be an alternative to consider in trying to avoid overloading this server… What is it? If you intend to use this service regularly on large scale, consider downloading the package and use it locally. The package available for download, although it may be slightly out of sync with the code running this service. The distiller can also run in XHTML+RDFa 1.0 mode (if the incoming XHTML content uses the RDFa 1.0 DTD and/or sets the version attribute). RDFa 1.1 Distiller and Parser Warning: This version implements RDFa 1.1 Core, including the handling of the Role Attribute. Classes and Subclasses An rdfs:Class is a set of elements - it is an organisational construct rather than a tangible object. These help define concepts more explicitly and also allow for inferences to be generated with a reasoning engine. RDFS and Inferencing Resource Description Framework Schema (RDFS) extends RDF with simple organisational constructions. Discussions on a possible next version of RDF A number of textbooks have been published on RDF and on Semantic Web in general. Recommended Reading The RDF 1.1 specification consists of a suite of W3C Recommendations and Working Group Notes, published in 2014. This linking structure forms a directed, labeled graph, where the edges represent the named link between two resources, represented by the graph nodes. Using this simple model, it allows structured and semi-structured data to be mixed, exposed, and shared across different applications. RDF extends the linking structure of the Web to use URIs to name the relationship between things as well as the two ends of the link (this is usually referred to as a “triple”). RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed. Basic Protocol 1: Introducing a node from the canvas Basic Protocol 2: Introducing a node from the query builder Basic Protocol 3: Exploring molecular relationships between diseases Basic Protocol 4: Find proteins with protein kinase activity involved in a disease and explore the context around them Basic Protocol 5: Exploring the potential downstream effects after targeted inhibition of proteins Support Protocol: Installation of the BioGateway plugin through the Cytoscape App Manager and from source.Ĭytoscape App RDF triple store SPARQL queries exploratory network building transcription factor regulation resource.Overview RDF is a standard model for data interchange on the Web. ![]() ![]() ![]() ![]() The use cases also provide examples to explore network information in other species, as they become supported by BioGateway. Network refinement and display can be further optimized via the selection and filtering possibilities that the Cytoscape framework provides. As the BioGateway information content is most abundant for human proteins and genes, this article describes the utility of the tool through a series of use cases on these human data, starting from the most basic levels and then detailing applications that address some of the rich complexity of the integrated data. The BioGateway App facilitates the step-by-step creation of complex SPARQL queries through an intuitive Graphical User Interface, allowing users to build and explore biological interaction networks to assess, among other things, gene regulatory relationships, gene ontology annotations, and protein-protein interactions. BioGateway contains information from several curated resources including UniProtKB, IntAct, Gene Ontology Annotations, various datasets containing transcription-factor regulatory relations to specific target genes, and more. The BioGateway App is a plugin for the Cytoscape network editor, allowing users to interactively build biological networks by querying the Biogateway Resource Description Framework (RDF) triple store.
