What is DEPUIS Design of Environmental-friendly Products Using Information Standards • The objective of DEPUIS is to improve the environmental friendly design of new products and services through the innovative use of new information standards. • Standards discussed in this presentation: • using URIs well (new ISO TC184/SC4 document) • RDF (Resource Description Framework) • Notation 3 (a concise and readable representation of RDF) • vocabularies from ISO 10303 (STEP), ISO 15926 (process plant)

Some metadata • Key information is: • either person readable text • or held by a PLM system • OK if: • you are completely informal; • you work solely through a PLM system • but what about the those us somewhere in between • Even a PLM system is not rigorous when it relates to outside systems an file formats • Who controls the identification of: • file format versions • analysis code versions • solution types • material behaviour types, etc. • What about files of data which remain outside the PLM system

Semantic Web "My document can point at your document on the Web, but my database can't point at something in your database without writing special purpose code. The Semantic Web aims at fixing that." Jim Hendler: former Chief Scientist of the Information Systems Office at the US Defense Advanced Research Projects Agency (DARPA).

What is a URI UniformResourceIdentifier – a unique ID for use on the Internet URN - UniformResourceName • use is highly controlled • ISO, ISBN, EPC have namespaces • only an identifier – no access mechanism is defined urn:iso:std:iso:15926:-4:tech:heat_exchanger HTTP URI(formerly URL - Uniform Resource Locator) • use is uncontrolled • starts with a domain name • HTTP access is defined http://www.esa.int/SPECIALS/Mars_Express/

Using URIs well • URIs identify things • an HTTP GET retrieves information about the thing, but not necessarily the thing itself http://www.esa.int/meetings/2007/nafems-esa/ identifier of the meeting – an HTTP GET returns an HTML page with a description of the meeting and links to other information such as agenda, hotels, transport – used as a keyword on timesheets

Using URIs well • URIs identify things • an HTTP GET retrieves information about the thing, but not necessarily the thing itself http://www.esa.int/meetings/2007/nafems-esa/invitation_letter identifier of the invitation letter – an HTTP GET returns the content

Using URIs well • URIs identify things • an HTTP GET retrieves information about the thing, but not necessarily the thing itself http://www.esa.int/meetings/2007/nafems-esa/presentation/ identifier of the set of presentations – an HTTP GET returns an HTML page with links to each

Mars Express: http://www.esa.int/SPECIALS/Mars_Express/ Using URIs well • URIs identify things • an HTTP GET retrieves information about the thing, but not necessarily the thing itself http://www.esa.int/meetings/2007/nafems-esa/presentation/SWTechForEA identifier of this presentation – an HTTP GET returns the content http://sci.esa.int/marsexpress/

shorthand for http://www.much_binding.gov.uk/road/MB_7 a unique identifier for the bridge assigned by the customer Telling a story mbcc:MB_7 rdfs:label ″Much Binding Bridge 7″ ; basic RDF vocabulary

shorthand for http://www.ice.org.uk/dictionary#Bridge “is a” or “of type” a concept defined and identified by a responsible organisation Telling a story mbcc:MB_7 rdfs:label ″Much Binding Bridge 7″ ; a civil:Bridge ;

http://www.nafems.org/dictionary#hasState An engineering analysis concept defined and identified by a responsible organisation Telling a story mbcc:MB_7 rdfs:label ″Much Binding Bridge 7″ ; a civil:Bridge ; ea:hasState adv:MB_7/HA_MidSpan .

Telling a story mbcc:MB_7 rdfs:label ″Much Binding Bridge 7″ ; a civil:Bridge ; ea:hasState adv:MB_7/HA_MidSpan . http://www.a.d.vance.co.uk/project/MB_7/HA_MidSpan a unique identifier for the state defined by the consulting engineer

If you don’t know what the term means you can go there with your browser. The vocabulary http://www.w3.org/1999/02/22-rdf-syntax-ns#type(or “a”) http://www.w3.org/2000/01/rdf-schema#label http://www.ice.org.uk/dictionary#Bridge http://www.nafems.org/dictionary#hasState

The objects http://www.much_binding.gov.uk/road/MB_7 If you go there, the council tells you about the bridge. There may be links to planning committee document. Some may be for planning committee members only. http://www.a.d.vance.co.uk/project/MB_7/HA_MidSpan This may be just an ID, so you can’t go there. This may take you into the A. D. Vance and partners project management system (for employees only).

part of a results data file within the A. D. Vance and Partners PLM system Telling a story – on to analysis adv:MB_7/HA_MidSpan a ea:State ; ea:hasStressDistribution adv:MB_7/run3/result#HA_MidSpan.stress .

http://www.hks.com/format/abaqus_v4.5/result A unique ID of an old file format Telling a story – what sort of file adv:MB_7/HA_MidSpan a ea:State ; ea:hasStressDistribution adv:MB_7/run3/result#HA_MidSpan.stress . adv:MB_7/run3/result a hks:abaqus_v4.5/result .

How this can happen – vendors 1 • Vendors • URIs for versions of analysis codes • URIs for versions of file formats • so you can record what you did and what you have http://www.hks.com/format/abaqus_v4.5/result for example: • perhaps just an ID - an HTTP access does not return anything • perhaps HTTP access returns: • which analysis code versions produced files of this format • information about the format

How this can happen – vendors 2 • Vendors • provide URI addressing into files for example: http://www.a.d.vance.co.uk/ project/MB_7/run3/result#HA_MidSpan.stress step_id.field_id • perhaps just a documented URI structure • perhaps used by visualisation software to go to the field to display

How this can happen – NAFEMS 1 • NAFEMS • define the basic vocabulary for analysis data • hasState • hasLoading • hasStressDistribution for example: http://www.nafems.org/dictionary#hasState • most work done in ISO 10303-104 • but hidden in an information model

How this can happen – NAFEMS 2 • NAFEMS • define the basic vocabulary for analysis workflow • createMeshFromGeometry for example: adv:task/MB_7-23 a ea:createMeshFromGeometry ; ea:usingTool http://www.siemens.com/nx/i-deas/v6.7 ; ea:hasInput adv:MB_7/masterGeometry ; ea:hasOutput adv:MB_7/mesh ; wf:performedBy adv-hr:FredBloggs ; wf:onDate ″2007-10-06″ . • most work done in ISO 10303-209 • but hidden in an activity model

How this can happen – others • engineering domains • define the basic vocabulary for civil engineering for example: http://www.ice.org.uk/dictionary#Bridge • materials • URIs for items in handbooks for example: http://www.dsp.dla.mil/Mil-HDBK-5/2014-AMS_4028-T6 • regulatory authorities • URIs for statutory design cases for example: http://www.dft.gov.uk/road/trunk/design/exceptional_load
