  6. Using emerging technologies • Identifying things by HTTP URIs • getting data about them by “dereferencing” • Data as RDF statements • readable RDF as N3 • a little bit of formality from OWL • The importance of standard RDF vocabularies • This is what will make it work • This is our task

  7. About URIs • a URI is just a string of characters • They are unique identifiers for things, which are used on the web • A thing can have more than one URI, but a URI identifies only one thing • HTTP URI • formerly called a URL • The use of an HTTP URI implies that an HTTP (HyperText Transfer Protocol) access, e.g. from a browser, is valid • But you may be disappointed and get “error 404” – no answer was the stern reply • a URN • A URI which does not imply any form of access • used by some organisations – e.g. ISO, ISBN • urn:iso:std:iso:15926:-2 The Web is based upon HTTP URIs – don’t worry about URNs

  8. What a URI identifies Uniform Resource Identifier • a web page • http://www.iom3.org/index.htm • You can open it with your browser – data is downloaded • You can follow links to other web pages • an object • http://www.iom3.org • This is the organisation Institute of Materials, Minerals and Mining • It has a Royal Charter – it cannot be downloaded to a browser • a formula • http://www.iom3.org/formula.n3 • This is a computer interpretable file of RDF statements about the IoM3 • It can be process by Semantic Web browser or by an application

  9. Dereferencing a URI “dereferencing” means attempting to get some data. You can only dereference an HTTP URI. • If the URI identifies a web page – you get it • If the URI identifies an RDF formula – you get it • It the URI identifies an object .... • The object could be the Eiffel Tower, or the Institute of Materials – neither can be downloaded to your browser • either you get nothing (error 404), or you are redirected to a “representation” access to http://www.iom3.org is redirected to http://www.iom3.org/index.htm

  10. A webpage http://www.iom3.org/index.htm The IoM3 has not implemented this – yet click to view the formula

  11. A formula engineering institution type “Institute of Materials Minerals and Mining” title http://www.iom3.org “+44 20 7451 7300” telephone webpage http://www.iom3.org/index.htm organiser “Materials Congress 2008” title http://www.iom3.org/congress-2008 webpage http://www.iom3.org/congress-2008/index.htm

  12. Clever browsers http://www.iom3.org/formula.rdf - Mozilla Firefox http://www.iom3.org/formula.rdf http://www.iom3.org/formula.rdf http://www.iom3.org/formula.rdf http://www.iom3.org/index.htm Is organiser of 2008

  13. Suppose you want a formula • Usually redirection takes you to an HTML web page • This is good, because a person may need to know what a URI identifies – the web page can tell him or her • If an application want the formula, then there are two options: • content negotiation – the HTTP protocol allows the GET request to specify the required format – RDF can be specified • link from the HTML file – this is hidden in the header and is used by applications when required

  14. Suppose you want a formula http://www.iom3.org/index.htm <html> <head> <title>IOM3 - Institute of Materials, Minerals and Mining</title> <link rel="alternate" type="application/rdf+xml" title="RDF Representation" href="http://www.iom3.org/formula.rdf" /> <meta name="description" content="Institute of Materials, Minerals and Mining“/> <meta name="keywords" content="IOM3, IOM, IMM, materials, world, academy, profession, science, engineering, metals, ceramics, polymers, glass, rubber, minerals, mining, plastics, institute, careers, jobs, journals, education"/> ...... link to the formula

  17. dereference to get a formula about the model An individual product http://packing-machinery.cn/item/08-12345 http://packing-machinery.cn/item/08-12345/formula.rdf @prefix rzm: <http://packing-machinery.cn/> . @prefix iso: <http://www.tc184-sc4.org/vocabulary#> . rzm:item/08-12345 iso:manufacturedBy <http://packing-machinery.cn> ; a rzm:model/ML1800 .

  18. who defines the vocabularies? – an ISO or IEC committee – a trade association A class of product http://packing-machinery.cn/model/ML1800 The Ruian Zhuxin Machinery Co has not implemented this – yet – as far as I know http://packing-machinery.cn/model/ML1800/formula.n3 @prefix rzm: <http://packing-machinery.cn/> . @prefix iso: <http://www.tc184-sc4.org/vocabulary#> . @prefix packing <http://www.packing.association.org/vocabulary#> . rzm:model/ML1800 iso:hasMass [ scale:kilogram 14000] ; packing:maximum_rule_length [ scale:metre 50 ] ; packing:speed [ scale:perMinute 16 ] ; packing:motorPower [ scale:kilowatt 11 ] ; ......

  19. Semantic Web - a big opportunity • Intelligent product selection • A super Google™ - You can search on semantically precise attributes rather than text strings • Automatic download into data sheets • Enter the URI of the product, and the relevant fields are filled in by download from the vendor’s site • Automatic validation that a product is really suitable for a role • System can flag an error if the properties of the selected asset are incompatible with the properties of the intended facility

  20. Making it happen • Basic Semantic Web technologies in place • But still very new – some key documents this year • Standardisation bodies assign URIs • URIs will be added to ISO 15926-4 early in 2009 • Need to drag the rest of ISO (and ASTM, DIN etc.) into the 21st century • Who is working on it – Process Industry IDS project • Aker Kvaerner • • ALCIM • • AVEVA • • Bechtel Corporation • • Bentley Systems • • DNV • FIATECH • • Intergraph • • iXIT • Noumenon Consulting• • • OLF • POSC Caesar Association • Statoil • • University of Stavanger

  24. What is ISO 15926 for? • To record facts, by the use of reference data • To record changes • Each fact can have a separate audit trail • Support for data warehousing • Large scope requires simple and generic approach
