Subject: Repository use cases::retrieval()
Terry: I recently received a report from the ebXML Repository groups' last conference call. It sounds like things are rolling ahead at break neck speed. I want to thank you for the invaluable work you have done and continue doing. In respect to the Submission, classification and retrieval of meta data in a repository, we (XML Global) have realized that the retrieval method will be greatly influenced by the classification methodology. IN general, retrieval methods fall into two categories: 1. A machine API which can accept a query, perform an RPC on the repository, and return the correct data. IT is imperative that the query be sent in a platform and O/S neutral syntax. Accordingly, the use of XML to build an XML Query Interface (XQI) for the goxml.com search engine was a logical choice. The details of the XQI are available at: http://www.goxml.com/xqi.htm I would like to submit this for discussion and test use for the repository group. 2. A human interface. This does not normally seem to be a necessity until you think about the use cases. Imagine a scenario whereby a party attempts to find a specific version of specific meta data such as a mapping template and fails via a machine API. The user should have a back up retreival mechanism to be able to perform a manual search on the repository. If they still cannot find a specific item (for arguments' sake a "mapping template"), they may be able to find a similar item or a different version of the same item which could be manually retrieved, modified and used. Also - in the case of SME's, not all parties may be able to afford the applications to automatically retreive the meta data. A manual system would definately lower the cost for entry into a global trading network. Thoughts... Duane Nickull
