Dear all, Apologies for cross posting. The IMS Query Services SIG which is run by Kerry Blinco of DEST and our very own Scott Wilson has recently posted a call for use cases on the IMS Public Website at: http://www.imsglobal.org/qscallforusecase.pdf The introduction to the call reads as follows: "29 March 2005 The IMS Query SIG is undertaking a pre-charter activity in writing a White Paper that explores the concepts associated with queries. The Query Services White Paper is being written for the purpose of eventually informing the development of specifications that use queries as part of their service definition. The requirement for this work is currently being driven by unmet requirements for Query identified by the IMS Enterprise, IMS Learning Design, and IMS Digital Repositories specifications. The intention of this call is to understand the requirements of the wider IMS community. For the purposes of the White Paper, a Query is a set of criteria that can be used to discover resources, and a Query Service is a specification for a service endpoint that, at a minimum, accepts a query and returns a set of results. A Query Service is distinct from a Resolver Service (which takes an identifier or a set of meta-data and returns a locator for the resource) and a Read Service (which takes an identifier and returns the resource identified). Therefore, IMS is making this wide and general announcement to the community for Use Cases that can be considered in preparation of the White Paper. A Use Case is a description of some activity usually involving a person and a computer system or between two or more systems. The proposed time-line is that the Query Services White Paper is targeted for completion in mid May 2005, and Use-Case contributions are requested by 15 April. " If you have a use case you would like the group to address you can submit it directly to IMS by emailing [log in to unmask] or via the “Use Case and Priorities” Forum at http://www.imsglobal.org/developers/ims/imsforum/ Alternatively I'm sure your ever helpful CETIS SIG coordinators would be willing to submit use cases on your behalf. If you have any questions about this call please don't hesitate to contact me and I will pass your query on to the appropriate IMS Query Service SIG member All the best Lorna -- Lorna M.
