Name: Dr. Wagner History First presentation of the need and requirements at the OGC meeting in Liège, March 2001 WPOS in GDI NRW Testbed I in 2001 Presentation of approach and concepts at the OGC meeting inLondon, June 2002 Discussion Paper OGC Doc: 02-39r1 L.A., Dec 2002 WPOS HTTP POST profile2003 Experience and Proof through multiple (paid) projects (LGB, LDS NRW, O.S.,Hamburg,..)

Name: Dr. Wagner Motivation: Geo-eBusiness Diversity with WPOS/XCPF

Name: Dr. Wagner Benefits There is a need to SELL geo-information to have revenues for further developments of SDIs !! XCPF: math. approach copes will a very wide range of pricing models & easy adjustments Support different protocols (a XSL file per protocol) Support of existing networks Implementation independent Automation of value chains Rationalization

Name: Dr. Wagner How does it cost? A non- trivial question Geo-Information products are not off-the- shelf products ! How to offer/price Geo-Services?

Name: Dr. Wagner Pricing in the Geo Domain Geo-product pricing is complex due to high value and very high prices wide range of configuration possibilities No suitable mainstream solution available ! Generic structures needed! The lowest common denominator for all pricing Ideas is the mathematical formula -Proofed- Product description in ISO 19115

Name: Dr. Wagner Example Position: 1 Top km² Shopping cart: Position: 3 Top 50 7 km² Pos. 2: f 2 (...) = 4340 Pos. 1: f 1 ((area(polygon), areaPrice(area), updatefactor dataformat, useCategory, userCategory, workstations, licensingTime, Taxes))= 1234 Pos. 3: f 1 ( ) = 987 Sum 6561 Position: 2 DHM 5 km² =>5982 Minimum Price, Taxes Scale Pricing: areaPrice = 17 km² * 0.9 /km² or areaPrice= 15 km² * 1 /km² + 2 km² * 0.9 =>1992 =>4340 Scaled areaPrice =>6341 => 5982

Name: Dr. Wagner XML Configuration & Pricing Format (XCPF) Object Axis XCPF hierarchy to group product items for complex group pricing integration of different catalogs optimizing with object inheritance product cascading

Name: Dr. Wagner XCPF: Product Object The smallest unit short description hosting the basic pricing formula hosting the product configuration(layer, style,pixel,...) workflow status all contract aspects

Name: Dr. Wagner XCPF: Calculation Object parameter groups multiple (intermediate) formulae external XCPF Web Service Calls formula encoding with W3C MathML

Name: Dr. Wagner WPOS Concept: Requirement no geo-data protocol interference, e.g. WMC WMS, WMS will never understand getPrice implementation independent no data service enhancement necessary but price calculation, ordering and accounting of requested geo-data support of additional configuration parameter, e.g. WMS request and configParam licenseTime multi-protocol support, e.g. WMS,WFS,WCS,… Protocol Packages and Layering

Name: Dr. Wagner Review After 4 solutions are carried out: No major problems appeared Therefore, only smart changes Usage of mathematic formulae a good decision Implementation- and protocol-independency is a key issue Other e-business approaches not helpful, e.g. UDDI, ECO, ebXML,XCBL We are confident enough to recommend the discussion paper to move on in the OGC acceptance process

Name: Dr. Wagner Preview Update OGC Discussion Paper 02-39r1 New HTTP POST profile with Schema Adjustments to latest Web Service Developments/Styles Façade Examples for WMS and WFS XCPF as description language in a separate Document Invitation to all interested institutions to join !
