52. A big work has to be done in order to semantize current data : - Different values for identifiation, ex Districts: '20e', 'XXe', '75020', 'PARIS 20', street names, etc.. - Many datasets not documented, semantization = meaning, is difficult - Some cells containing differently formatted values, multiple lines on multiple cells - ~80% of ESRI geo data without metadata Two main issues to resolve : Objects identification Types determination

54. ★ 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) ★★★ use non-proprietary formats (e.g., CSV instead of Excel) ★★★★ use open standards from W3C (RDF and SPARQL) to identify things, so that people can point at your stuff ★★★★★ link your data to other data to provide context http://www.w3.org/DesignIssues/LinkedData.html TBL : << The Semantic Web isn't just about putting data on the web. It is about making links, so that a person or machine can explore the web of data. With linked data, when you have some of it, you can find other, related, data. Like the web of hypertext, the web of data is constructed with documents on the web. However, unlike the web of hypertext, where links are relationships anchors in hypertext documents written in HTML, for data they links between arbitrary things described by RDF,. The URIs identify any kind of object or concept. But for HTML orRDF, the same expectations apply to make the web grow >>
