Agenda/Minutes

Agenda

- Action Items & Progress reports

Jeff DLB sent in Use Case, Brief XML
George sent in term definitions
Compusult sent in Use Cases

- Term definitions

Discussion of Allan's email "Re: Service definitions from Topic 12" - Arliss suggests to put the word "neccesarily" back into the service definition.
Jeff DLB suggests that we should provide "final" definitions of terms for inclusion into WMS 1.1 prior to May 9.
Lou talks about a new UML Modelling book - Addison Wesley series, "Modelling XML applications with UML"
Operation = atomic unit
Interfaces are a group of Operations
Lou says we don't need Interfaces because we're not dealing with state. Arliss says we're talking about general terminology, we have to handle stateful cases.
George suggests we look at UDDI terms. Lou seconds this.
Lou says we have a 3 level model
George says we have 4: Service Prover, Service, Interface, Operations

Lou - let's look at a combo WFS/WMS. How does it map into any of our models?

- New business...

Doug's PPT slides (and .PDF version) - Slides 2 & 3 refer to the diagram Doug drew on the board at the last meeting. The basic idea is that you may look for data, then when you find data, you ask what services are available on the data you found. c.f. diagrams on lower right of Liege whiteboard picture. The underlying assumption is that the data holder decides which service instances the data is made available under. E.g. a data holder may only provide WMS access to it and that's the service UUID that you get back. Lou asks about the cases where data holders make their data available for other service providers to access and provide a value-added service on top of that data. The "3rd party" services, such as a reprojection service would probably not be attached to the data via the service UUID mechanism. These scenarios provide requirements on the metadata.

Doug's envelope message - read it and discuss it...

Bill Pope - is there anything lower than operation in terms of parameters of the operation? Answer - look at BSM discussion paper for initial discussion on that

Jeff Lansing's agent thread. Don't tie definitions into requiring a human as the end-user of a service/operation.

Servicemodel group would like to see rough draft of WMS 1.1

Meetings for OGC TC week for this group - tentatively Monday AM and Thursday PM.
