Open Data Institute - Knowledge for everyone
Slides: http://files.meetup.com/1462944/welcome-to-odi-open-data-certificate.pdf
The Open Data Institute acts as catalyst for the evolution of an open data culture to create economic, environmental, and social value. It helps to unlock supply, generate demand, create and disseminate knowledge to address local and global issues.
Tom will begin this talk by introducing the "what, why and who" of the ODI, before describing a current project designed to help data owners understand and adopt social, legal and technical best practices for data publication.
Tom Heath, Data ScientistAs Data Scientist, Tom's job will be to support those teams, at the ODI and elsewhere, who want to find and exploit the value in Open Data. He will be doing this by wrangling and linking openly-licensed data sets to maximise their usability and utility, and by sharing the lessons learned. Tom was previously at the Talis Group, where he led internal research and data science programmes drawing heavily on Open and Linked Data, and consulted on these topics for large media and governmental organisations including the BBC. Having been an early and long-standing contributor to the Linking Open Data community Tom has witnessed first-hand the transformative potential of Open Data in enabling novel initiatives and communities, and is passionate about furthering this trend at the ODI. Academically Tom's background is in Psychology (BSc) and Computer Science (PhD), but he says that "nothing beats the tangible satisfaction of hands-on data crunching".
Mapping Relational Databases to RDF with the new W3C Recommendations: A Case Study based on MusicBrainz - Barry Norton
Slides: http://www.slideshare.net/EUCLIDproject/r2-rml-londonsemweb201304
Late last year the W3C released two recommendations for publishing Linked Data from relational data sources: the Direct Mapping and the RDB-to-RDF Mapping Language, R2RML. The mapping from the MusicBrainz dataset, which includes many 'advanced relationships' missing from previous mappings, is one of the largest applications of R2RML to date, and presents a near-unique opportunity for large-scale examples and benchmarking. Dr. Barry Norton, who was part of the team originally mapping the MusicBrainz Next Generation Schema with the MusicBrainz Foundation, and maintains the updated mappings and public SPARQL endpoint will present this case study and provide insight into the provision of a large dataset using the developing technologies supporting the standard.
As mentioned by Barry one of the tools produced by capsenta called Ultrawrap is available as a preview for Lotico members now here:

Dr. Norton is a Solutions Architect with Ontotext AD, and supports several other major deployments of Ontotext's OWLIM RDF database technology.
Training Event Info
In addition Barry is going to lead the Semantic Technologies Introduction, a free introductory seminar on April 11 from 4pm to 6pm. The course aimed at people who use or intend to use semantic technologies for data management, publishing, content analysis. It is targeted at senior managers, IT professionals and individuals who are interested in gaining a thorough understanding of the basic concepts and standards around the Semantic Web. It is also a foundation for the Semantic Technologies with OWLIM course offered the following day on April 12th as a professional training event. These training courses are going to take place at the Hac.
