LINKING THE DATA 13
5 STAR OPEN DATA 14https://5stardata.info/en/ Tim Berners-Lee, the inventor of the Web and Linked Data initiator, suggested a 5-star deployment scheme for Open Data: * make your stuff available on the Web (whatever format) under an open license ** make it available as structured data (e.g., Excel instead of image scan of a table) *** make it available in a non-proprietary open format (e.g., CSV instead of Excel) **** use URIs to denote things, so that people can point at your stuff ***** link your data to other data to provide context
LOD BASED ON GRAPHS 15 URI URI URI URI URI URI URI URI URI URI URI
LINKED OPEN DATA (LOD) 16 • distributed / decentralised information management • interactive information search and reasoning over the web • sharing partial data http://tomheath.com/blog/2009/03/linked-data-web-of-data-semantic-web-wtf/

MISSION STATEMENT 39 Bring together experts in the area of Building Information Modeling (BIM) and Web of Data technologies to: 1. define existing and future use cases and requirements for Linked Data based applications across the life cycle of buildings. 2. discuss best practices for publishing building data on the Web 3. propose ontology models to describe: ▸ Buildings and building elements (topology, associate values to properties) ▸ Products and product properties 4. discuss how they can be used together with other specifications: ▸ existing standards (IFC, GeoSPARQL, Semantic Sensor Network, ...) ▸ separate initiatives (schema.org, Haystack, BRICK, ...) http://w3.org/community/lbd/
