Putting the L in front: from Open Data to Linked Open Data

2. Open Government Data is a worldwide movement to open data (& information) of the government / public administration* - that is NOT personal (individual related) – in human- and maschine readable open formats (non proprietary) for use & re use! OPEN stands for lowering the barriers to ensure as broad as possible re-use (for everybody)! There is a new paradigm in publishing Open Government Data = look, take and play! * ….. data and information produced or commissioned by government or government controlled entities What is Open (Government) Data?

CC-BY-SA von campuspartybrasil (flickr) Linked Data realizes the vision of evolving the Web into a global data commons, allowing applications to operate on top of an unbounded set of data sources, via standardised access mechanisms. I expect that Linked Data will enable a significant evolutionary step in leading the Web to its full potential. The Vision of the new Internet

20. LOD – Huge Economic Potentials http://www.mckinsey.com/mgi/publications/big_data/index.asp Data have swept into every industry and business function and are now an important factor of production, alongside labor and capital . Harnessing big data in the public sector has enormous potential, too. If US health care were to use big data creatively and effectively to drive efficiency and quality, the sector could create more than $300 billion in value every year . Two-thirds of that would be in the form of reducing US health care expenditure by about 8 percent. In the developed economies of Europe , government administrators could save more than €100 billion ($149 billion) in operational efficiency improvements alone by using big data, not including using big data to reduce fraud and errors and boost the collection of tax revenues. And users of services enabled by personal location data could capture $600 billion in consumer surplus.

37. Interoperabilty & Standards Henry Maudslay (1771 – 1831) He also developed the first industrially practical screw-cutting lathe in 1800, allowing standardisation of screw thread sizes for the first time. This allowed the concept of interchangeability (a idea that was already taking hold) to be practically applied to nuts and bolts. Before this, all nuts and bolts had to be made as matching pairs only. This meant that when machines were disassembled, careful account had to be kept of the matching nuts and bolts ready for when reassembly took place. http:// en.wikipedia.org/wiki/Henry_Maudslay John Sheridan, OGD2011 Conference, Vienna, Austria: http://www.slideshare.net/semwebcompany/linking-uk-government-data-john-sheridan/
38. Also take the Metadata into account! Towards Open Government Metadata (Sept 2010) In the EU eGovernment Action Plan semantic interoperability is mentioned “…as an essential precondition for open, flexible delivery of eGovernment services ”. Metadata Ignorance Public administrations should become aware of the importance of Metadata in eGovernment and the need for coherent relevant management policies. Scattered or Closed Metadata Public administrations should organize the scattered Metadata in structured repositories, catalogues or libraries and provide open access to the collected resources. Open Metadata for Humans & Open Reuseable Metadata Public administrations should provide services to query, browse and export their Metadata in a machine-readable and preferably non-proprietary format (e.g. CSV, XML). Linked Open Metadata Public administrations should consider applying linked metadata policies, including use of RDF to document their Metadata, persistent design, use and maintenance of URIs, linking to external vocabularies/schemata, harmonize their resources to third parties' resources etc. http:// www.semic.eu/semic/view/documents/towards_open_government_metadata.pdf
