ISO the role of Façades

Program The five presentations are dealing with:  what are reference data (taxonomy) and what object information models (ontology)?  data and documents  what are templates, why and how do we use them? more on OIMs (Object Information Models)  mapping, hand-over, exchange, and query of data what is the role of the Façades? what is the role of the Façades? Presentations already given can be downloaded from here here

Data Ownership Data ownership means that the owner may: createpublishexchangeupdatedelete the data he/she owns The owner cannot update or delete his/her data once this has been exchanged

Present Situation Users of applications: use data created by othersuse data created by others create/update datacreate/update data publish/exchange data for use by otherspublish/exchange data for use by others This means pushing and pulling gazillions of data between applications, resulting in a lot of data duplication How do you know whether or not the imported data is still valid?

Data Exchange (& Duplication!)

Data Exchange For this (customary) data exchange normally XML is used In order to provide means for validation of data an XML Schema is designed, providing the rules for any compliant XML file XML files are self-contained and all-inclusive, i.e. anything you refer to must be included in the file This calls for data duplication In a globalized economy a more manageable way of lifecycle data sharing is required

New (ISO 15926) Situation Each owner publishes his/her owned data (no more, no less) on an ISO Part 7 Façade Using the standard Semantic Web technologies of the W3C (World Wide Web Consortium) any non-owner can access that data (provided he/she has read-only access rights!) and then use it as input for his/her application(s)

Using Façades

Data Sharing

Data Exchange [1] In cases where a precisely defined data set must be sent to someone else ISO provides the means to do that by sending a Message like this: TRM DOC DOC DOC TRM e.g. Purchase Order e.g. data sheet for P-101 e.g. data sheet for P-102A&B March 12th, 2006 at 2:58 pm GMT

Data Exchange [2] This Message is "pushed" to the addressee Upon receipt that addressee then can "pull" all data from wherever they are stored (depending on the URIs) by means of a predefined SPARQL query This then results (here) in three complete documents (e.g. purchase order + data sheets)
